Fertilizing trees -- better late than never?
Bought some tree-fertilizer spikes recently and found out, that they are supposed to be used in "early spring" or "late autumn".
Is using it now still better than nothing at all, is it a waste of fertilizer, or is it, perhaps, even worse than not fertilizing at all?
One box of the stuff is meant for fruit trees (I have cherry, sour cherry, apricot, and pear) and the other box -- for evergreens (cypress trees)...
Any suggestions? Thanks!
