I've had several bushes (7) in ground for several years. I followed the most common online information - acidifying the soil with iron sulfate, fertilizing with ammonium sulfate. They have produced some, with lack luster growth. Please don't ask the varieties, although I bought them and there are different ones for cross pollination, I never labelled them.
This year I am watering by hand with acidified water, and ammonium sulfate added once a week, hopefully to help them grow and produce.
So the questions -
How much water does each bush need? Some of them are small (2 ft, 3 branches) while others are "large" (3-4 ft tall, 2-3 ft across).
How much fertilizer does each bush need? I've been giving each 1 Tbs ammonium sulfate per week.
I've adjusted the pH of the water to 4.0 - 4.5... too low?
Each bush gets some compost every year, as well as compost tea on occasion, and is well mulched. I have about 6" of good topsoil with dense clay under that. I assume most of the roots stay in the topsoil. Since they are really just starting this year, I cannot tell if the acidified water is helping.
Thanks!
