Peach Trees and fertilizers
What fertilizers are y'all using for container peaches. I have a tropic snow that seems to be stalled out. It hasn't put in any more growth since the spring flush and its in a 30 gallon pot. I've been using Micro Life fert but I also have Ammonium sulfate, Aluminum sulfate, and Citrus Avacado fert that I could use. It does seem to be a little N2 deficient as the the mature interior leafs are lighter shade of green while the newer leafs are dark green. Would the one teaspoon Ammonium sulfate in 2 1/2 gallons of water be appropriate here?
