Fish fertilizer question

whidn

I like to use a Miracle Grow auto mixing thing to feed my trees, You know the one you hook on a hose and put fertilizer in the bottom of it. I usually put about 2 caps full of Alaskan Fish Fertilizer in the container and feed about every 2 weeks.

My question is, Is this too much or not enough?
I seem to be getting good results with this mixture but if I can put more food to my trees without harming them than I will.

"I seem to be getting good results with this mixture"...over what time period have you been using the technique?

I believe the Alaska Fish fertilizer is pretty weak, (i.e.,5-2-2), when used full strength. Placing a small amount in a hose end sprayer ( to fertilize how many trees??) would make it hard to determine what concentration you were actually providing to the trees... If this has been your practice for a long while, I guess it works! If this is a recent method with no track record, I'd be on the lookout for signs of deficiency eventually.
I use full strength ( according to package directions) Peter's, Miracle Grow, or similar every two weeks during the active growing season, and they seem to like the attention. I may supplement with higher phosphorus for flowering trees, use a special formulation for acid loving trees, or eliminate most nitrogen during fall and winter.

Some like to fertilize "weakly, weekly"...half of the package directions more frequently. I suppose that would also work. Bill Valavanis looked into his methods of soluble fertilizer use in the past and felt full strength was the best option.
