    I think that you will have to talk with your local law enforcement on this one. We can't really help with things of this nature.

    The best thing you can apply under a tree is mulch out to the dripline. Trees have shallow feeder roots that shouldn't be disturbed by planting under it. Especially since you have a mature, 22 year old tree, I would just enjoy the shade.

    However, if you are committed to planting, here is an article that tells how to plant without disturbing the roots too much:

    Yes! Many can cross-pollinate with crab apples. This is a common practice on commercial orchards to increase pollination rates.

    If you just had a snow and frost last week, it may not be time to "wake up" yet. Are other trees in the area blooming yet? Other crabs? I think it is still dormant. It is within your hardiness zone so winter should not have hurt it. According to the Maine Extension publication below, crab apples bloom at the end of May or early June, so it should do something soon.

    This can be quite normal for a year or two, as it adjusts to planting. I would make sure and put a HANDFUL of DOLOMITIC LIME, and a TABLESPOON of WETTABLE SULFUR around the tree. Do this once a year, and fertilize it with a fruit tree fertilizer once per year in spring, or use mulch or compost each year.
