Birch question, any Tree People?
We have just had to really disturb/prune a lot of Birch roots to get the ground ready for an underplanting of perennial Geraniums. It is a small grove of Birches planted in the center island (approx. 38' x 18') of a circle driveway.
I am wondering what i can do to minimize the shock damage to the Birches. With another kind of tree I wouldn't be too worried and would just take the water to them, but I know that Birches are shallow rooted and don't particularly like to have their feet wet.
The soil in the island is mostly on the sandy side which is good, but we are having an extraordinarily WET summer.
Any suggestions? Xtra water or not? Xtra mulch maybe? or not?
The help is very much appreciated.
