Ditto on not cutting any of those beautiful trees!
Also... I wouldn't attempt bringing in soil in a vain attempt to create planting areas in the tree root zones.
Easy to smother the trees...
Personally... I'd be looking at covering everything in a nice woodchip mulch.
You don't need that turf in your beautiful woodland garden!
Unfortunately, bleeding hearts are not a good southern garden plant.
Chinese wisteria is a tree killing thug.
Possibly you have a native wisteria... Does it bloom before it leafs out or later?
I took down the page I used to have up with a southern shade garden... But there are a ton of wonderful plants for the shade... But... NOT AGAINST the trees!
You seem to want to plant the trees's root zone... And that isn't going to work.
