Ryan has been out of that fertilizer since last year, I keep checking back but it always says sold out.
I do have a few thousand individually wrapped tree-prep tablets that are just for this purpose I will likely use. I just got frustrated looking online for any clear information on this. I found an article from Oregon State University that says --> "Nitrogen or other macronutrients should be applied in the second year. Research indicates that applying fertilizers
in August or early September maximizes nutrient uptake and is more efficient than late winter fertilization. Early season fertilization is often leached. Late summer to fall fertilization at the time of your last irrigation is taken more directly into the tree, helping to make healthy buds, spurs and shoots for the coming year without stimulating late growth."
That goes against the grain of everything else I have read regarding when to fertilize trees.
Fruit trees like apples, pears and prunes generally need fertilizer. Learn how to match your orchard's needs with the macronutrients the soil can provide.
