Vitamins for trees?
June 1, 2014 8:48 AM Subscribe
I've planted a variety of trees around my house - kwanzan cherries, tulip trees, flowering crabapples - and many seem to have shared problems. These are 1) extra thick trunks for their size, 2) a tendency toward something like witch's brooming, and 3) a tendency to grow off vertical. No basic nutrient problems on soil testing, but haven't done trace minerals. Should I break up with them, or is there someway to work this out?
