Q.Azaleas
We have an Azalea, of which did flower Ok last year. This year the buds appear and then just rot away before they open out and flower. We did fertilize the plant with Azalea grow, also fed it with Epsom Salts and Aquasol. Would like to know what we should do to get it back to normal flowering.
Thanking you.
Allan.
This could be caused by the boytritis virus or is could be due to Thrips.
Avoid overhead watering of your plant.
