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
Metallic striped beetles eating leaves and flowers. Most active autumn and spring.
Cause
Chrysolina americana. Affects lavender, rosemary, sage, thyme, marjoram.
Organic treatment
Hand-pick adults and larvae. Shake over a sheet. Pyrethrum spray.
Prevention
Check plants regularly. Avoid hiding spots at base.
What to look for
White coating on leaves. Leaves yellow and drop. Common on sage and mint.
Cause
Various Erysiphe fungi.
Organic treatment
Remove affected leaves. Improve airflow. Neem oil spray.
Prevention
Water at soil level. Ensure good spacing.

Recommended Varieties

  • Common Chives (standard)
  • Garlic Chives (flat leaf, garlic flavour)
  • Siberian Chives (very cold-hardy)
Garlic chives (Allium tuberosum) are a distinct species with flat leaves and a gentle garlic flavour — excellent for Asian cooking.
Crop Rotation — rotate every 3 years
Allium family (Alliaceae)
Avoid planting after: Onions, garlic, leeks, shallots — share white rot
Good to follow: Brassicas, root vegetables, tomatoes
Same rotation rules as onions — white rot can persist long-term.

Storing Your Harvest

Room temp
2–3 days in a glass of water
Fridge
1–2 weeks wrapped in damp paper towel
Freezer
Snip and freeze in ice cube trays with water or olive oil — excellent
Frozen chives lose texture but keep flavour perfectly for cooking.
