Pests and diseases

Common problems and what to do.

The most common problems in Central Europe. Protection is listed from the gentlest option.

What you will see

Irregular holes in soft leaves and young shoots and slime trails; they feed at night.

How to protect

  1. Prevention
    • Plant sturdy potted plants, not delicate young seedlings.
    • Water in the morning, not the evening (evening watering helps them move around).
    • Encourage their natural enemies: birds, hedgehogs, toads, ground beetles.
  2. By hand evening, after rainPick them off by hand on damp evenings and take them far away. Traps: hollowed-out citrus halves placed cut side down, or sunken containers of beer; check in the morning.
  3. Biological when the soil is warm and moistSlug-specific nematodes (from a biological control supplier) are watered into the soil.
  4. Chemical — only when nothing else helps according to the product labelLast resort only: a product authorised in your country against slugs and snails. Try non-chemical methods first.

What you will see

Pale spots on leaves that turn into spore pustules mainly on the underside of leaves (orange, yellow, brown, black or white); in severe attacks yellowing and early leaf drop.

How to protect

  1. Prevention
    • Grow in warmth, sun and free-draining soil; tarragon dislikes damp, so do not overwater.
    • Clear fallen leaves, remove diseased parts quickly, clean tools and weed.
    • Do not over-feed with nitrogen — soft new growth is quickly attacked.
  2. By handFor light attacks, strip off affected leaves early; remove large amounts carefully. Do not compost summer/autumn debris (spores overwinter).
  3. Chemical — only when nothing else helpsFungicides are not recommended; for edible crops, gardeners have no fungicides available with good efficacy against rust.
