Symptoms

- Buds fail to open but stay on the bush looking silvery, and later in spring develop black 'bristles'. The buds remain on the plant for two or three years, but don't rot. The 'bristles' are the spore bodies of a fungus which is believed to be introduced by the rhododendron leafhopper laying its eggs in flower buds. Adult leafhoppers occur on the foliage from mid-July until October. They are 8mm long with yellow head and legs, a blue-green thorax, and forewings striped with red.

Rhododendron dies off

Question from Toni Fernandez

Hi,

I seem to have a problem with my plants, they seems to be OK until the top leaves sort of dry out and curl up and this affects the flower buds too, one died already last year, the other two are producing new green leaves from the top (where the buds were), but not sure they'll not get the problem too!

I think I am doing everything right (mulching, pH, moisture, etc), but plants are simply not happy!! Please help!!

I'll try to add some pics asap

Thanks a lot!
