Q.Can I Fertilize Multiple Times?
I have a maple that likes 55/15/30. I also have a bag of 18/6/12 fertilizer. Can I use that bag on my maple, fertizing three times since 18/6/12 x3 = 54/18/36? I had planned to fertilize in March, April, and May.

Fertilizing trees is not an annual chore. It should be done on an as-needed basis. If you've been fertilizing yours yearly, I would hold off on any more for a few years. You can take a soil test to see if anything is amiss. Here is more information:
