My fuchsias, I have about 40 plants, are slowly dying. I cut them back and now their growth is stunted. I've lost 2 and I really hope I don't lose any more. I feed them Osmocote and treat them with Bayer mite contol when they have the gall mite.

If their growth is stunted after being cut back, I would look at the roots for the issue. It could be a fungal form of root rot, which has spread to all the plants or it may be that you have a pest attacking the roots. Treating the soil with a fungicide can't hurt, but if you can find out what is getting at the roots, then you will be better able to treat the issue.
