Whats causing the brown leaves and dead flowers on azalea?
Hi there, my friend has a standard azalea planted in each of 2 long planters amidst some bedding plants. Think they have only been in a couple of weeks. On one, the leaves have started to turn brown and the flowers dying off. I thought it may be fungal or over-watering, but he says he has watered both same amount. Asked him if planted in ericacious or just multipurpose compost, he doesn't know as a friend gave him some leftover (I think this means it may just be multipurpose). I advised to remove the worst of the leaves and any on the soil for now. Have attached couple of photos. Would be very grateful if anyone can help with a solution to rescue this beautiful plant. Many thanks Cath (sorry, first time on one of these forums so sorry if I've not done it right!)
