wonder if you could tell me the best thing to feed gerberas with.
I have a lot of plants and this year they have not done so well.
They seem to have some sort of rust on their leaves and haven't
flowered as they did last year. As yet I haven't fed them anything.
gerberas have rust, a fungal disease which is prevalent in warm,
humid weather. Spray your gerberas with a fungicide such as Greenguard
or Fungus Fighter. Reapply at 7-10 day intervals. Pick up any fallen
leaves and burn or dispose of them in the rubbish bin. Badly infected
leaves should be removed.

Osmocote controlled-release fertiliser or Magamp. Follow the application
rate on the pack and water in well. Feed regularly throughout the
