I notice that my Victoria plum trees have a very sticky substance on leaves and fruit. Could you please let me know what is causing this and if there is anything I can do now to remove it. There is a very heavy crop which I have already thinned.

The sticky substance is probably the honeydew from greenflies which can infest a plum tree and cause reduced growth and cropping.
These may need to be controlled with an insecticide, if the tree is not too big, but usually they disappear about mid-summer, predators and parasites having arrived.
Keep under review.Â
