Elderberry

in Zone 3, this week

Elderberry is a large, easygoing native shrub that gives big clusters of small dark berries for making juice, syrup, jelly, and pies. It is very cold-hardy, handles wet soil, and starts producing in just two or three years. Remember two things: plant two different varieties so you get plenty of fruit, and always cook the berries, because raw berries, leaves, and stems can make you sick. Elderberry is a big, fast, tough native shrub grown for its clusters of small dark berries, which are cooked into juice, syrup, jelly, wine, and pie (and its flowers are used too). It is one of the easiest fruits to grow: very cold-hardy, wet-tolerant, and productive within two or three years. Two things are non-negotiable: plant two different cultivars for good yield, and always COOK the berries, because raw or unripe fruit, leaves, and stems are mildly toxic.

Chill hours

Will your winter chill these blueberries?

Elderberry needs a cold winter rest, but not much, and you do not pick varieties by chill the way you do with blueberries; there is basically one kind of elderberry. The only place low winter cold matters is the frost-free deep South, where it can make fruiting less reliable.Elderberry is a deciduous shrub that rests dormant each winter and needs a period of cold to do so, but its chill requirement is low and, unlike blueberry, is NOT how you choose a cultivar: there is essentially one type (American elderberry) grown everywhere. In practice, winter dormancy is a given across its hardy range, and the low-chill point only matters at the frost-free warm edge, where too little cold can make bloom and fruiting erratic.

Your elderberry year, month by month

Deciduous, drops its leaves in winter Northern Tier, Zone 3

Your elderberry is a long-lived, very cold-hardy bush you plant once and keep for years. It loses its leaves and rests in winter, grows fast in spring, flowers in early summer, and ripens dark berries in late summer. Prune the oldest stems in late winter, and plant two different varieties for plenty of fruit.Elderberry is a permanent, very cold-hardy deciduous shrub, planted once and renewed in place for many years. It rests bare and dormant through winter, leafs out and grows fast in spring, blooms in early summer, and ripens clusters of dark berries in late summer, after which you renew the oldest canes in late winter. Plant two different cultivars for good fruit set.

Once established, your blueberries follow the same yearly rhythm. Choose a cultivar by chill class above, then use this calendar for the season-to-season timing.

From seed to fruit

The growing journey

Stage 01 · Planting

Planting

Your new elderberry going into rich, moist soil, at the same depth it was growing before.A dormant bare-root plant or rooted cutting going into moist, fertile soil, typically late winter to spring; container plants can also go in during fall.

Plant in rich, damp soil at the same depth it was before, water it well, and mulch around it. Plant two different varieties near each other.Plant in moist, fertile soil at the depth it grew, water in well, and mulch. Plant at least two different cultivars for cross-pollination.

FROM PLANT · Plant at least two different varieties near each other (within 60 feet) so they pollinate and give you much more fruit. Pick a moist, sunny spot with room to spread.Plant two or more DIFFERENT cultivars within about 60 feet for cross-pollination; elderberry is only partially self-fertile and yields far more with a partner. Choose a moist, sunny, roomy site.

Establishment (year 1)

Your young elderberry growing roots and stems, not a real crop yet. This lasts about the first year.A young plant putting its energy into roots and new canes rather than fruit. Elderberry establishes fast, so this stage is short.

Pinch off the flowers the first year so the plant grows strong instead of fruiting. Keep it watered and mulched.Remove the flower clusters the first year so the plant builds roots and canes. Keep the soil evenly moist and mulched.

FROM PLANT · Pinch off the flowers the first summer so the plant grows strong. It grows quickly, so you will get berries soon anyway.Remove the flower clusters in the planting year so the plant builds roots and canes. Elderberry establishes fast, so this brief restraint costs little and pays off in year two.

Spring growth and budbreak

Each spring the plant leafs out and sends up fast new growth from the base.Vigorous new shoots and canes leafing out from the base and from last year's wood each spring. Growth is fast now.

In spring, feed with a balanced fertilizer or compost (starting year two), and keep the soil damp.Feed once in early spring (from year two) with a balanced fertilizer or compost, and keep the soil moist as growth takes off.

FROM PLANT · In spring, feed with a balanced fertilizer or compost (starting year two) and keep the soil damp. Go easy, since too much fertilizer makes weak, floppy stems.Feed once in early spring (from year two) with a balanced fertilizer or compost, and keep the soil evenly moist as the fast new canes emerge. Do not over-feed, which makes floppy growth.

Bloom

Big flat clusters of creamy-white flowers open in early summer. Bees visit them, and a second variety nearby means more fruit.Broad, flat, creamy-white flower clusters (cymes) opening in early to midsummer. They are wind-pollinated and worked by many insects, and need a second cultivar nearby for good set.

Let the bees work, and make sure another elderberry variety is blooming nearby. You can pick a few flower clusters to use, but leave most to become berries.Make sure a second, different cultivar is blooming nearby. You can harvest some flower clusters for cordials or fritters, but leave most to set fruit.

FROM PLANT · The flower clusters are edible; pick a few for cordials if you like, but leave most to become berries. Make sure another variety is blooming nearby.The broad creamy cymes are edible too: you can cut a few for cordials or fritters, but leave most to set fruit, and make sure a second cultivar blooms alongside for good pollination.

Fruit set and sizing

The flowers turn into tiny green berries that grow into full clusters, turning from green to purple over a few weeks.Pollinated flowers set small green berries that fill out over several weeks into heavy clusters, deepening from green to red to purple-black. The most water-sensitive window.

Keep the soil damp while the clusters grow, and get netting ready before the berries darken.Keep moisture steady while clusters size, and net the shrub or plan bird control before the berries color.

FROM PLANT · Keep the soil damp while the clusters fill out, and net the shrub before the berries darken, because birds can strip them quickly.Keep moisture steady while clusters size, and get bird protection in place before the berries color; birds are the top competitor and can clear ripe clusters fast.

Ripening and harvest

Clusters turn deep purple-black in late summer. Cut off whole clusters when most berries are dark and soft. Always cook the berries.Clusters ripen to deep purple-black in late summer. Cut whole cymes when most berries are dark, plump, and soft; berries do not ripen further after picking and must be cooked.

Snip off whole ripe clusters, pull the berries off the stems, throw out unripe berries and stems, and cook or freeze them soon.Cut whole ripe clusters with pruners, strip the berries from the stems, discard green or red berries and all stems, and cook, freeze, or dry promptly.

FROM PLANT · Snip off whole clusters when most berries are dark and soft, pull the berries off the stems, and always cook them. Never eat raw or green berries, or the leaves and stems, which can make you sick.Cut whole clusters when most berries are deep purple-black and soft, strip them (chilling the clusters helps), discard green or red berries and all stems, and ALWAYS cook before eating: raw and unripe fruit, leaves, and stems are mildly toxic.

Post-harvest growth

Once the berries are done, the plant keeps growing leaves and building up for next year.After harvest the plant keeps growing and stores energy in its canes and roots for next year. Late-season growth should slow and harden before frost.

After picking, keep it watered, but stop feeding by late summer so it toughens up for winter.Keep the plant watered and healthy; stop feeding by late summer so growth hardens off before winter.

FROM PLANT · After picking, keep the plant watered but stop feeding by late summer so it toughens up for winter. A healthy plant now means more berries next year.Keep the plant watered and healthy after harvest, but stop feeding by late summer so the canes harden off before frost. A vigorous plant now sets up next year's heavy crop.

Winter dormancy

In winter the plant loses its leaves and rests. It is very cold-hardy and needs little attention.The shrub drops its leaves and rests dormant through winter, fully cold-hardy. In frost-free regions it slows but may not go fully bare.

Not much to do in winter. Keep mulch on, and give a little water only in a dry, mild winter.Little is needed: keep mulch in place and do not let the roots sit bone-dry in a mild, dry winter.

FROM PLANT · Elderberry rests over winter and is very cold-hardy, so there is little to do. Keep mulch on and plan your late-winter pruning.Elderberry is fully cold-hardy and needs little winter care; keep mulch in place and only water in an unusually dry, mild winter. Late winter is the time to plan pruning.

Dormant-season pruning and cane renewal

In late winter, while the plant is bare, cut out the oldest canes (over about three years old) and any dead or crowded stems. An overgrown plant can be cut to the ground to start fresh.In late winter, while the shrub is leafless, do the annual pruning: remove canes older than about three years, plus dead, weak, or crowded stems, keeping vigorous young canes. Neglected clumps can be cut to the ground to renew.

Cut the oldest canes off at the base and thin out crowding, leaving strong young stems. Throw away the trimmings to keep borers down.Remove the oldest canes at ground level and thin the clump for a balance of one-, two-, and three-year-old wood. Destroy prunings to reduce borers.

FROM PLANT · In late winter, cut out the oldest canes (over about three years) and any dead or crowded stems, leaving strong young ones. A neglected plant can be cut right to the ground to start fresh.Each late winter, remove canes older than about three years plus dead and crowded stems, keeping a mix of young wood. An overgrown, unproductive clump can be cut to the ground to renew it.

Beginner

Know your soil

Your soil

Identify yours

Not sure what soil you have? Grab a small handful of damp soil from your garden bed and squeeze it. If it crumbles apart easily, it's sandy. If it holds together but breaks when you poke it, it's loam (what most vegetables want). If it stays in a hard, slippery ball, it's clay.

What this crop wants

Elderberry wants rich, moist soil and is happy in spots that are too wet for most fruit. Work in plenty of compost, keep it damp, and it will thrive; the only soil it really dislikes is dry, droughty sand.

If your soil doesn't match

You have sandy soil

Mix 2-3 inches of compost into the top 6 inches of your bed before planting. Compost holds moisture (which sandy soil drains too fast) and adds the nutrients sandy soil tends to lack. Repeat each season. Compost breaks down over time.

You have clay soil

Mix 2-3 inches of compost AND a few inches of coarse sand or perlite into the top 6 inches of your bed. The compost feeds the plants; the sand breaks up the clay so air and water can move through. Don't add sand without compost. It can compact like concrete.

Containers and raised beds

If amending your soil sounds like too much work, or if your soil is heavy clay, full of rocks, or contaminated, build over it. A raised bed at least 12 inches deep filled with a 50/50 mix of compost and sandy loam gives you ideal growing soil with no battles. A 5-gallon container with quality potting mix does the same for one plant at a time. Both bypass your native soil entirely.

Preferred

5.5 to 6.5

Tolerated

5.5 to 7.5

Elderberry is relaxed about soil pH, doing well anywhere from about 5.5 to 6.5 and tolerating up to around 7.0. Unlike blueberries, it does not need acidic soil, so no special treatment is required. A basic soil test is all you need.Elderberry prefers a soil pH of about 5.5 to 6.5, but it is easygoing and grows well from slightly acidic up to near-neutral (roughly 5.5 to 7.5). Unlike blueberry, it needs no special acidification: a soil test and ordinary garden pH management are plenty. If anything, keep it out of strongly alkaline ground.

Steady hand on the hose

Watering

When & how much

Frequency

Water regularly so the soil stays damp, about 1 to 2 inches a week and more in hot, dry weather. Elderberry likes moisture and does not handle drought well.Keep the soil consistently moist. Elderberry is a streambank plant with shallow roots and a real thirst; it wants steady moisture through the whole growing season and especially while berries are sizing. Roughly 1 to 2 inches of water per week, more in heat and on sandy ground.

Amount

About 1 to 2 inches a week, including rain, and more when it is hot and dry.1 to 2 inches per week, adjusted for rainfall, heat, and soil; more on sand.

Method

A soaker hose or drip line at the base works best, and a thick mulch keeps the soil damp between waterings. Elderberry is fine with wet soil, so err on the side of more water, not less.Drip or soaker irrigation keeps the shallow root zone evenly moist; a thick mulch holds moisture and keeps the roots cool. Elderberry tolerates wet soil, so the usual risk is under-watering, not over-watering.

Signs of trouble

Too much water

Elderberry rarely drowns; only dead-still, swampy soil causes yellow leaves and rot. Most of the time you cannot give it too much water.Elderberry tolerates wet ground, so overwatering is rarely a problem; only in truly stagnant, airless soil will you see yellowing and root decline.

Too little water

Wilting leaves, crispy edges, and small, shriveled berries mean the plant is too dry. Elderberry is one of the first plants to sulk in a drought.Drought stress shows as wilting, scorched leaf margins, undersized berries, and early leaf drop, worst on sandy soil and during the fruit-sizing window.

Balanced, with nitrogen

When to start

in early spring as growth begins

Feed elderberry once a year in early spring, starting the second year, with a balanced fertilizer like 10-10-10 or a good layer of compost. Do not feed at planting time. Elderberry grows fast on its own, so go easy; too much fertilizer makes weak, floppy stems.Elderberry is a moderate feeder that responds well to nitrogen and organic matter. Do not fertilize at planting; from the second year on, apply a balanced fertilizer such as 10-10-10, or a generous topdressing of compost or aged manure, once in early spring as growth begins. A vigorous plant that is putting up strong new canes usually needs little more; over-feeding just makes soft, floppy growth.

Who grows well together

Companion planting

Elderberry does not need companion plants. It is a large shrub, so give it plenty of space and keep it from shading smaller plants. Its one real planting rule is to put a second, different variety nearby so the two can pollinate each other. Elderberry is not a companion-driven crop; it is a big, vigorous shrub best sited for its own sake. The main rules are practical: give it room (it reaches 8 to 12 feet and suckers), keep it where its size will not shade smaller sun-loving crops, and lean into its strengths as a pollinator and wildlife plant and a tolerator of wet, low ground. Its most important 'companion' is simply a second, different cultivar nearby for cross-pollination.

Other

Native pollinator flowers

Elderberry flowers feed bees and other insects, and its berries feed birds. Planting native flowers nearby supports all that life and looks good together.Elderberry is a strong wildlife and pollinator plant: its broad cymes are worked by many insects and its fruit feeds birds. Interplanting native flowering perennials nearby broadens the pollinator support around bloom and fits elderberry's role as an edge or hedgerow shrub. This is companionship by shared habitat, not a tested yield boost. Well-grounded

Harvest signals

When to pick

Elderberries are ready when most berries in a cluster are deep purple-black, plump, and soft. Snip off the whole cluster with pruners instead of picking one berry at a time, then pull the berries off the stems (freezing the clusters briefly makes this easy). Skip any green or red berries, keep the stems out, and always cook the berries before eating.Harvest whole flower-cluster heads (cymes) when most of the berries in a cluster have turned deep purple-black and are plump and soft, usually late summer. Cut the entire cluster with pruners rather than picking berries one by one, then strip the berries from the green stems (chilling or briefly freezing makes this easy). Leave green or red under-ripe berries, and never include stems. Berries do not sweeten after picking, and they must be cooked.

Yield

What to expect

A mature elderberry bush usually gives about 10 to 15 pounds of berries a year, more with good soil, plenty of water, and a second variety nearby for pollination.A mature, well-grown elderberry commonly yields roughly 10 to 15 pounds of berries per year, sometimes more on the most productive modern cultivars in good, moist soil. Yield climbs quickly as the shrub fills in and is heavily dependent on cross-pollination and moisture.

Elderberry produces quickly. You will get a small crop the second year and close to a full crop by year three or four, then good harvests for years with regular pruning.Elderberry is fast: expect a light crop the second year and something close to full production by years three to four, far quicker than blueberry. A well-managed, renewed planting stays productive for many years. Do not expect berries the first year, and pinch off the flowers that first summer so the plant grows strong. Elderberry is quick, so you will be picking real crops by year two or three.Expect little or no harvest the first year, and remove the flower clusters that season so the young plant builds roots and canes. It grows so fast that this costs you almost nothing: real crops arrive by the second or third year.

What changes yield

Cross-pollination: two or more different cultivars with overlapping bloom sharply raise yield.Cultivar: modern selections such as Bob Gordon and Wyldewood out-yield the older standards.Consistent moisture: drought during fruit sizing cuts both cluster size and total yield.Full sun: fruiting is heaviest in full sun; shade reduces the crop.Cane renewal: annual removal of the oldest canes keeps a balance of productive young wood.Fertility: a moderately rich, well-fed soil supports the heavy growth that carries the crop.

Pick your variety

Recommended varieties

There is really just one kind of elderberry to grow, American elderberry, so pick varieties by how much they yield and when they ripen, not by your climate. The important thing is to plant two different varieties near each other so they pollinate and you get far more fruit. Good pairs are Adams with York, or Bob Gordon with Wyldewood.Elderberry is not split into climate types the way blueberry is: nearly every home and commercial cultivar is American elderberry (Sambucus canadensis), and you choose by yield, ripening season, and habit rather than by chill. The one rule that matters is to plant at least two DIFFERENT cultivars with overlapping bloom for cross-pollination, which sharply raises yield. Classic pairings are Adams with York, or a modern Missouri pair like Bob Gordon with Wyldewood. European elderberry (S. nigra) cultivars exist and can be grown too, but the American types are hardier and better adapted across most of the country.

Storing your harvest

Room temp

Do not leave fresh elderberries out; use or refrigerate them the same day. And do not snack on them raw, because raw elderberries can make you sick. They are meant to be cooked, juiced, or dried.Fresh elderberries are highly perishable and should not be held at room temperature; process or refrigerate them the day you pick. Remember they are NOT a fresh eating fruit: raw ripe berries are unpleasant and mildly toxic, so plan to cook, juice, or dry them rather than store fresh.

Fridge

In the fridge, elderberry clusters keep only a few days, so plan to use them quickly. A handy trick: freeze the clusters for a bit, then the berries pop off the stems easily with a fork. Keep the stems out of whatever you make.Refrigerated on the stem in a breathable container, elderberry clusters hold only a few days (roughly 2 to 5). It is best to strip and process the berries promptly. To de-stem easily, chill or briefly freeze the whole clusters, then rake the berries off with a fork; keep the green stems out of your finished product.

Freezer

Elderberries freeze well. Freeze the clusters, then rake the frozen berries off the stems into a bag; they keep about a year. Cook them before eating.Freezing is the easiest way to hold elderberries. Freeze the clusters whole, then rake off the berries while frozen (they come off cleanly), bag, and store; frozen berries keep good quality for about a year. Always cook them before eating, whether fresh or thawed.

When something goes wrong

Common problems

Little or no fruit

01 of 05

What happened Your elderberry grew fine but made few berries. Usually this means it has no second variety to pollinate with, it is too shaded, or frost hit the flowers.The shrub grew well but set few or no berries. The usual causes are a lone plant with no second cultivar to cross-pollinate, too much shade, or a late frost on the flowers. Next season Plant a second, different variety within about 60 feet, give it full sun, and cover the flowers if a rare late frost threatens.Plant at least two different cultivars with overlapping bloom within about 60 feet, site it in full sun, and protect early bloom from a rare late frost.

Fruit disappearing as it ripens

02 of 05

What happened The berries disappeared right as they ripened. This is almost always birds getting at unprotected fruit.Clusters vanished just as they ripened. This is almost always birds, the number-one competitor for elderberries, reaching unprotected fruit. Next season Cover the shrub with netting before the berries darken, or grow a drooping-cluster variety like Bob Gordon, and pick as soon as ripe.Net the shrub before berries color next season, or grow an inverting-cyme cultivar such as Bob Gordon that hides the fruit, and harvest promptly.

Feeling sick after eating the berries

03 of 05

What happened Someone got an upset stomach from the elderberries. Raw or unripe berries, and the leaves and stems, can make you sick because they contain natural toxins. Cooking the ripe berries makes them safe.Someone felt nauseous or unwell after eating elderberries. Raw or unripe (green or red) berries, and any leaves, stems, or seeds, contain cyanogenic compounds that can cause nausea, vomiting, and diarrhea. Cooking the berries destroys these. Next season Always cook elderberries before eating. Use only fully ripe dark berries, keep the stems and leaves out, and never eat them raw or eat green or red unripe berries.Always cook elderberries before eating. Use only fully ripe purple-black berries, keep all stems and leaves out, and never eat the berries raw or the green or red unripe ones.

Individual canes wilting and dying

04 of 05

What happened A cane suddenly wilted and died, and the stem was hollow inside. This is a borer grub tunneling in the cane.One or more canes suddenly wilted and died back, with hollowed, tunneled stems when cut. This is cane and shoot borers whose larvae tunnel inside the wood. Next season Cut off and throw away the wilting canes right away, and cut out old canes each winter to keep borers down.Prune out and destroy affected canes below the damage as soon as you see wilting, and renew old canes each dormant season to break the borers' cycle.

Overgrown thicket with poor fruiting

05 of 05

What happened Your elderberry turned into a big tangled thicket that makes few berries. Elderberry fruits best on younger canes, so old ones need removing.The plant became a dense, tall, tangled thicket that fruits poorly. Elderberry canes fruit best when young; without renewal, old canes dominate and yield falls. Next season Prune it: each late winter cut out the oldest canes, or cut the whole overgrown plant to the ground and let it regrow fresh and fruitful.Renew the planting: each late winter remove canes older than about three years, or cut a badly neglected clump to the ground to force fresh, productive growth.

The usual suspects

Pests & diseases

Pests

Birds

P · 01

Symptoms Birds eating the berries, sometimes clearing a bush fast once the fruit ripens.Ripe and ripening berry clusters stripped from the shrub, often the whole crop in a few days as the fruit blackens. Cause Birds love ripe elderberries and are the biggest pest for the fruit.Elderberries are a favorite of many birds, which are widely the number-one competitor for the crop. Organic treatment Cover the bush with bird netting before the berries darken, and tuck it in at the bottom. Some varieties (like Bob Gordon) droop their clusters and lose fewer berries to birds.Drape bird netting over the shrub or a frame before the clusters color, secured at the base. Cultivars whose cymes invert (droop) after fruit set, such as Bob Gordon, hide the berries and lose less to birds. Prevention Put netting up each year before the fruit ripens, and pick as soon as clusters are ready. Shiny tape and fake owls stop working once birds get used to them.Net before ripening every season; harvest promptly and completely so ripe fruit is not left hanging. Scare devices help only briefly.

Spotted-wing drosophila and sap beetles

P · 02

Symptoms Tiny maggots in soft ripe berries, or little beetles on overripe fruit, with clusters going mushy.Small maggots inside softening ripe berries (spotted-wing drosophila), and small dark beetles feeding on overripe or damaged fruit (sap beetles); clusters ferment and leak. Cause A small invasive fly that lays eggs in good ripe berries, plus beetles that show up on overripe fruit.Spotted-wing drosophila (an invasive vinegar fly) lays eggs in healthy ripe fruit; sap beetles are drawn to overripe and split berries. Organic treatment Pick ripe clusters often and clean up any dropped or overripe berries. Chill the harvest fast. A cup of apple cider vinegar makes a simple monitoring trap.Harvest ripe clusters frequently and completely, and remove fallen or overripe fruit (bag it, do not compost). Cool the harvest quickly. Monitor with apple-cider-vinegar traps. Prevention Pick often, keep the ground clear of fallen berries, and refrigerate promptly.Tight, frequent harvest and good sanitation are the core controls; do not let ripe or overripe fruit sit on the plant or ground.

Elder shoot and stem borers

P · 03

Symptoms A cane or shoot suddenly wilting and dying, with a hollowed-out, tunneled stem.Wilting or dying individual canes and shoot tips; hollowed, tunneled stems, sometimes with sawdust-like frass at entry holes. Cause Beetle and moth larvae that bore into and hollow out elderberry canes.Native borers, including the elder shoot borer and the elderberry longhorned borer, whose larvae tunnel inside canes and shoots. Organic treatment Cut off and throw away any wilting, tunneled canes right away to remove the grubs inside. Keep the plant healthy and prune out old canes.Prune out and destroy wilted or infested canes below the damage as soon as you spot them; this removes the larvae. Keep plants vigorous and renew old canes. Prevention Prune out old and damaged canes each winter and get rid of the trimmings, which removes overwintering borers.Annual removal of old and damaged canes during dormant pruning breaks the borers' cycle; destroy prunings rather than leaving them nearby.

Aphids

P · 04

Symptoms Tiny soft bugs on new shoots and leaf undersides, sometimes with sticky residue.Clusters of small soft-bodied insects on tender shoot tips and leaf undersides, sometimes curling new growth and leaving sticky honeydew. Cause Small sap-sucking insects that cluster on new growth.Several aphid species feed on elderberry sap; heavy colonies distort growth and can spread viruses. Organic treatment Spray them off with water, let ladybugs help, or use insecticidal soap for heavy outbreaks. Do not over-fertilize.Knock light infestations off with a strong spray of water, support natural predators like ladybugs, and use insecticidal soap if needed. Avoid excess nitrogen. Prevention Do not over-feed, welcome helpful bugs, and check new growth in spring.Keep plants healthy without over-feeding, encourage beneficial insects, and inspect new spring growth.

Japanese beetles

P · 05

Symptoms Leaves chewed to lace by shiny beetles in summer.Skeletonized leaves (chewed to lacework between the veins), usually in early to midsummer, sometimes on the flower clusters. Cause Shiny green-bronze beetles that eat the leaves in summer.Adult Japanese beetles feed on elderberry foliage and flowers where the pest is established. Organic treatment Pick the beetles off into soapy water in the morning. A healthy elderberry shrugs off most of the damage.Hand-pick beetles into soapy water in the cool morning; a vigorous elderberry usually outgrows the damage. Skip lures, which draw more beetles in. Prevention A strong elderberry handles a few beetles fine; keep it healthy and pick off the worst.Tolerate light feeding on established shrubs; keep plants vigorous. Grub management in nearby lawn reduces local populations.

Diseases

Elderberry rust

D · 01

Symptoms Orange spots and odd swollen growths on leaves and stems, with some leaves curling.Bright yellow-orange spots and swollen, distorted growths on leaves, stems, and flower clusters; affected leaves may curl. Cause A rust fungus that moves between elderberry and nearby sedge plants.A rust fungus (Puccinia) that alternates between elderberry and nearby sedges as its other host. Organic treatment Cut off and throw away the infected parts, and clear out any sedge weeds growing nearby. Keep the bush open and airy.Prune out and destroy infected shoots and clusters, and remove sedges growing near the planting to break the fungus's cycle. Good airflow helps. Prevention Give the bush room and airflow, keep sedge weeds away, and cut out any infected growth you see.Site plants in the open with good air movement, keep sedges away, and remove infected tissue promptly.

Powdery mildew

D · 02

Symptoms A white powdery coating on the leaves, mostly late in summer.A white to gray powdery film on leaves, usually late in the season; heavy cases can dull foliage but rarely harm an established shrub. Cause A common leaf fungus that shows up on crowded plants in late summer.Powdery mildew fungi, favored by crowded growth and poor air movement in late summer. Organic treatment Open up the bush by pruning so air moves through. It rarely does real harm.Prune to open the canopy for airflow and remove badly affected growth; established elderberries usually tolerate it without treatment. Prevention Keep the bush open and do not over-feed it.Space and prune for good air movement and avoid excess nitrogen that fuels dense, soft growth.

Cane canker and dieback

D · 03

Where to plant next year

Crop rotation

Crop rotation is for vegetables you replant each year. Elderberry is a shrub that lives in one spot for years, so just pick a good moist, sunny site and leave it there.Rotation does not apply to elderberry. It is a long-lived perennial shrub that occupies the same spot for many years, so choose a moist, sunny, roomy site up front, since you will not be moving it.

Avoid following

This does not apply to elderberry. You plant it once and it stays put for years, so there is nothing to rotate.Not applicable. Elderberry is a permanent woody shrub planted once and kept in place for many years, so it is not part of any crop rotation and there is no prior crop to avoid following.

When plant taps you on the shoulder

The plant app sends a timely reminder at every critical moment of your elderberry season. The wording adjusts to whichever you pick: beginner or seasoned. Here are three you'll see in Zone 3.

plant

0 days after planting

Plant two different varieties

Plant at least two different kinds of elderberry near each other (within about 60 feet) so they pollinate each other. You will get far more berries.

plant

0 days after first growth

Feed and water in spring

When the plant leafs out in spring, feed it with a balanced fertilizer or compost (from year two) and keep the soil damp.

plant

0 days after establishment

Pinch off flowers the first year

The first summer, pinch off the flowers so the plant grows strong roots and stems. You will be picking real crops by next year or two.
