All of my indoor plants are infested with tiny flies in the compost. They really are becoming unbearable as they can be found all over the house. Fairly sure they are mushroom flies as I can see the larvae in the compost. I know that keeping soil dry might help but I have cucumber,chilli and squash that need regular water. Had the same problem last year. Have tried spraying with general bug repellent but no good. Is there anything I can use to get rid of these horrible pests?

I have been growing tomatoes for many years in a greenhouse. In the last few years I am loosing a lot of tomatoes in the early stages as they fall from the plant at the knuckle just before the truss. Not all are lost but certainly the majority fall as if they had been cut off. Can you advise?

2 Pears trees with promising crop now show serious mosiac like splitting on some and brown spotting on all fruits. Is this weather related or disease?

Our Beech hedge is about 13 years old and we (ourselves) have kept at a height of 12 foot. Its about 500 feet long but does not have a tapered shape. It looks beautiful and gives great privacy but from a maintenance point of view we really find it too high and we feel we need to reduce its height by 2 to 3 feet. The trunk is pretty thick and I'd say the easiest way out is to take chain saw to it (hope I'm not frightening you!) or take the winter to gradually saw each plant by hand. How would you go about this? Many thanks.

I have a skimmea japonica repotted in a large pot recently, but now i have noticed the top surface of the leaves seem to be ate away by something they are left with white patches as if the green surface was eaten away. i cant see any insects on it anywhere.
