We have 12 1/2 acres, so space is ample here! Not all of it usable acreage though, since it is rather steep because it's a river canyon. But, there is at least 5 acres for tree planting, so I will get several River Birch. Birch seem to do well here too, which is a bonus! I'm just trying to get ideas on different trees, since if they were all the same, that would be a little boring!
We have several wild elderberry down the hill, and they are HUGE! I'm thinking about growing some of those, too, if I can get them started from cuttings. I brought a couple of small ones from my last house that I started from cuttings, but they will probably only get about 10 to 12 feet high. They make nice filtered shade! I just haven't figured out where to put them yet.
Sorry to hear about your weeping cherry, but it's good that it's bouncing back. Those trees are so beautiful!
