How to use Ammonium Sulfate on blueberries
I have a large bag (Lily Miller) of Ammonium Sulfate, and I want to use it to fertilize blueberry plants I have in different size containers (1 gal, 5 gal, 15 gal). Because I'm mindful of damaging the blueberries by over fertilizing them, I'd like to ask for some specific instructions on how much to use with each container. The general instructions (on the bag and elsewhere)for plants in general is to toss a handful around the plant. I'm hoping for something a bit more detailed than that. Any ideas about this?
