Neglected to fertilize this year
I haven't yet fertilized my rhody this year, I'm assuming I should have done this early spring...I have Rhody Cunninghams White. Lots of buds last year (1st year, no blooms), no buds this year that I've seen, but nice new growth, some winterburn.
The only thing I did this year was add small amount of gypsum to the soil...I was told this would increase acidity and promote looser soil in future years.
Should I fertilize now? No fertilizing after June for my zone?
