I live in a relatively new housing development and the builder was kind enough to plant three trees in my yard. They range from 9-15 ft tall but they are all rather wimpy, each having a trunk diameter of a few inches.
Not having an entire lifetime for these to grow to full size naturally, I'd like to help them along. I'm considering plumbing several of those tree irrigation spikes into my irrigation system and watering the trees weekly for a TBD duration of time. That said, If I won't see much growth improvement, I'm not terribly interested in the hassle -- The trees are health, just not very big. Would these type of setup help speed up the tree growth?
