When to look
How to protect
- Prevention
- Plants in a hot, dry, overcrowded greenhouse suffer more: increase humidity and airflow.
- In autumn, remove heavily infested plants and clear away debris, canes and ties; disinfect the greenhouse thoroughly.
- Weed around the greenhouse; weeds are hosts.
- Biological March to OctoberPredatory mites (from a biological control supplier) are the most common biological control against spider mites.
- Chemical — only when nothing else helps according to the product labelLast resort only: a product authorised in your country against mites. Try non-chemical methods first.
