It is obviously too late now to save my Brussels sprouts and broccoli from the ravages of caterpillars. We used netting, but it was apparently not a fine enough mesh. But what about next year? I do NOT want to use the insecticides you suggest... a bit surprised that you did! Am always concerned about any poisons with food - but also fear their effects on non-target species... and the birds etc. which eat the larvae.

Our garden is recently becoming infested with clusters of tiny, slim black worms (12mm max) feeding on tunnel strawberries, fallen apples, tunnel and outside lettuces - any soft fruit/vegetable in contact with ground. Are these a kind of eelworm and how can they be controlled.

I have a well established Pyracantha hedge. Over the last year I have noticed that a portion of it has begun to yellow and it seems to be dying off a little. The leaves have what look like scorch marks. It is a south facing hedge so I thought it might be sun scorching but the problem only seems to be effecting one portion of the hedge. I have included a photo of the problem. It is probably worth mentioning that I took about two foot of the top of the hedge a few years back. Maybe it was damaged then.What is your opinion?
