Q.Fertilizer
I am transplanting asparagus from seed trays to multiple cell trays. When, how much, how to apply, and what type of fertilizer (including superphosphate) do you recommend? Can I apply it as a liquid?
You can start fertilizing your asparagus seedlings once they develop their second set of true leaves. Give them a weak general purpose water-soluble fertilizer mixed 1/4 strength. Fertilize only once a week.
