I am relatively new to Austin and I do not know where to buy some goods like ammonium sulfate (I have an old pear tree with what seems phosphorus-induced iron deficiency)
Can anybody help me?
I could have sworn I saw them at Lowes or Home Depot. I don't think it is recommended that they be used during hot temperature???
Lowes at N35 and West Parmer has 20lb bag. I just pick one up last week.
