Biennial — feeds moderately. Monthly balanced feed. Avoid high nitrogen which reduces flavour intensity.

Example product: Espoma Herb-Tone
Reminder: every 28 days after feeding

Succession Planting

Sow every 4 weeks

Sow a second batch 4 weeks after the first. Parsley is slow to germinate (3–4 weeks) and biennial — in its second year it bolts immediately. For practical purposes treat it as an annual and sow a fresh batch mid-season. The second sowing will be producing vigorously through autumn and into early winter in mild zones. Soak seeds overnight before sowing to improve germination speed.

Indoors — 10 weeks before last frostHarden off required
Start 10–12 weeks before last frost — slow germination (3–4 weeks). Soak seeds overnight. Transplants fine. Harden off over 5 days.
Container friendly · Minimum 1 gallons
Excellent container herb. 8 inches deep minimum (taproot). Window boxes work well.

Pests & Diseases

Know what to look for before it gets out of hand — early identification is the most important step.

What to look for
Clusters of tiny soft insects on new growth and leaf undersides. Leaves curl, yellow, or become sticky with honeydew. Sooty black mold may follow.
Cause
Multiple aphid species. Populations explode rapidly in warm weather.
Organic treatment
Blast off with strong water jet. Apply insecticidal soap or neem oil directly to colonies. Introduce ladybugs or lacewings.
Prevention
Plant marigolds and nasturtiums nearby. Avoid excess nitrogen fertilizer which creates soft, aphid-attractive growth. Encourage beneficial insects.
What to look for
Root damage and wilting. Cilantro and dill are in carrot family and attract same pests.
Cause
Psila rosae. Affects all members of the carrot family.
Organic treatment
Grow under fine insect mesh.
Prevention
Insect mesh. Grow away from carrots and parsnips.
What to look for
Dark brown spots on leaves. Affected leaves yellow and die.
Cause
Bacterial or fungal leaf spot. Favoured by wet conditions.
Organic treatment
Remove affected leaves. Copper-based fungicide.
Prevention
Water at soil level. Good spacing.

Recommended Varieties

  • Italian Giant (flat-leaf, superior flavour)
  • Forest Green (curly, decorative)
  • Hamburg (root parsley — both root and leaf edible)
Flat-leaf (Italian) parsley has significantly more flavour than curly types — use curly for garnish only.
Crop Rotation — rotate every 2 years
Carrot family (Apiaceae)
Avoid planting after: Carrots, parsnips, celery, dill — share carrot fly and diseases
Good to follow: Legumes, brassicas, alliums
Parsley is in the carrot family — rotate away from other Apiaceae crops.

Storing Your Harvest

Room temp
3–5 days in water
Fridge
2 weeks in water in the fridge covered with a bag
Freezer
Blanch briefly, squeeze dry, freeze — or blend into oil cubes
Flat-leaf parsley stores better than curly. The water-glass fridge method is highly effective.
