*raises hand* Zone 8b or 9 deep coastal south
I have a question about trees. I have mentioned several times in my garden journal that I live on what was once a tobacco farm. They builder just brought in loads of builders sand to level the spot for the houses and built on them. We have a lot of trouble growing certain things, and even though most agricultural chemicals are supposed to leach out of the soil after a period of ten years of rain AND sun, there are still some issues, and it may not be chemically related. At any rate, on one side of my house I have trouble growing any kind of native tree. Period, it doesn't matter what it is, redbud, dogwood, peach, apricot, pine, etc. they die. It just so happens that is the area that I have tried to put the orchard. :/ That is the background to my question. Close to that area I planted a gingko tree five years back, and it has come back every year, until this one. They are notoriously slow growing trees, so although I was concerned about it, I didn't worry once it leafed out for the year. This year however the top has died over the dormant season and it only has suckers at the bottom. Those suckers have come out every year, but have withered and died over the growing season, when the regular leaves came out on the trunk. I had one clump of leaves come out on the main trunk about a foot off the ground, but it withered within a few weeks. One other thing, there are lichens growing on the six foot trunk, and on some of the branches. I don't know as much about trees as I do about some other things, and know next to nothing about gingko. Should I cut the trunk off, to help the suckers grow, or will that kill them? Should I try to dig the suckers up and separate them, and grow them elsewhere? Should I leave it alone.. and if I do is there a possibility that it will resprout next year from the trunk that seems to be dead right now? I love this tree.. and want to do what will most likely result in its survival in some form or other.
