Full question:
I have a TERRIBLE infestation of aphids all over my pumpkins, courgettes, and cucumbers. I have had to pull out the pumpkins because it was like a carpet all over the back of the leaves. I have sprayed with the soapy water several times. Is there anything that can be done or should I just pull all the plants out?

Our response:
Spraying with neem oil will do the job. Spray all over your plants, lifting up the undersides of the leaves – 3 times, 3 days apart each time, in the evening.
No need to pull your crop out. This should do it.
Have you got any flowers nearby? Flowering plants attract the beneficial predators which will deal to the aphids, so always a good idea to have either a bed of flowers (which we call an insectary) near your veges or flowers planted in and around the veges.
All the best!
