Pests Guide
Yellowing and discoloured leaves on runner beans, French beans and peas
They generally live underneath plant leaves and suck the chlorophyll from the foliage causing the leaves to change colour
Use neem oil or insecticidal oil
Use garlic spray to deter pests.
Crush 5-6 cloves of garlic and pour over 1 litre of boiling water.
Leave to cool and strain into a spray bottle.
If you add a teaspoon of liquid soap, this can help the spray stick onto the leaves.
Spray this liberally onto your plants and repeat in a couple of days time.
There is no danger of overdosing garlic spray so reapply whenever you like!
Mist the greenhouse with a fine water spray during hot weather.
Mites prefer dry conditions.
Higher humidity may encourage diseases though, so watch for signs of mildew.
Remove unwanted plants from greenhouse in autumn.
Cleome – these grow quite large so only one or two might be needed.
Bugs will hide out in flowers and foliage
