This bush was in a bad place. Dry, north side of the house, shaded on 3 sides. It was droopy and not enough room. I grew it from a cutting about 7 years ago. This bush had branches too tall for me to reach the top, so about 9 feet tall. But all of the leaves were wilted. They have been repeatedly wilter most of the summer. I don't water it enough.
Doesn't look great, but on planting and watering, the few remaining leaves perked up nicely. My theory is that forsythia is so tough, and cuttings root so easily, and it does have a good root mass. So I think it will have a set back, and of course won't bloom next spring. But I think it will establish and be a nice bush by next summer.
Pic to add tomorrow after it has the cool night to soak up water.
Added the next am:
The forsythia leaves perked up nicely. I think it will do OK.
