  My pyracantha has produced loads of berries and been fairly healthy I think, but I notice that in parts there are lots of brown leaves and wonder is this is the nature of the plant or does it need feeding. If so, what and when?
  
  Many thanks.

  There shouldn't really be a lot of brown leaves - have you checked for insect infestations such as scale?

  Thanks for reply. I've been to take a look and can't see any sign of scale insect but the plants are very sad - dry crispy leaves and berries and some fine 'cobwebs' Could it be pyracantha scab and what do I do to treat it? Also could recent hard frosts have caused the damage? The plants are well established - does old age bring this kind of problem?
  
  Thanks again

  The cobwebs suggest that the problem might be the caterpillars from a particular moth, which cover branches in a thick mass of cobwebs; the branch will then die. The caterpillars themselves are brown and very difficult to spot. I'd suggest that you take out the dead wood and look out for any sign of cobwebs. When you see these, brush them off and spray with Provado Ultimate Bug Killer.
  In the meantime, give your plant a good feed (anything will do - Growmore, MiracleGrow, etc..).

  I have got 12 of them and quite a few got badly damaged by the severe temperatures of last winter and the winter before, largely through snow settling on them and then freezing hard. Last spring I had to cut away a lot of dieback but much of what I left had lost all leafage but produced new leaves in spring. You should see new growth in a few weeks and that may give an indication as to whether the damage is superficial.

  Thanks both for your advice - you've given some me hope for recovery - will be out there tomorrow with the secateurs, a bug spray and a large tub of Growmore!
  
  Thanks again
