RE: Fertilizing Crab apple trees??
duckwacker -
What are you calling "crabapples"?
I'm curious - because in my neck of the woods - people oftern refer to American Hawthorn (thornapple) as crabapples.
If that were the case for you - I'd say - don't spend to much time on those thorny "apple" trees. I've yet to see a deer that will seriously eat this fuit - though I'm sure others will say they have - it probably depends on what else is available.
If the crabapple are just "wild apple trees" - then I'd place 10-10-10 around the drip line - about 1 handful per inch diameter of the trunk - like I do for regular apple trees.
