hello, We planted a Katsura tree in our front yard about 15 years ago. In hindsight the tree is probably too big for our front yard but I don’t know if that’s a big problem. What’s been happening over the last three years is that the leaves turn yellow and drop early. This year about half the leaves are already yellow on August 1. We live in Vancouver and there are other very tall trees near us so our Katsura does get some shade. I’ve read that the Katsura is not very drought tolerant and 15 years ago I didn’t guess that would be an issue for us. The soil around the tree is very dry. The tree is maybe 35ft tall. Would watering help the tree or is it too big for watering? Any estimates on how much water it would require? I’m not sure it makes sense to dump a bunch of water into a tree that is going to continue to struggle.
