Long story but because of a landscaper error, we had this block wall built and trees and other plants in it. It then had to be raised by a foot. The 4 cypress trees are huge and I am worried they will not survive digging them up and replanting them. We are adding soil to the block wall (one foot) and the gardener I hired is putting all that soil around them. I think it will kill the trees. He says it will be ok. Any ideas of what I could do? Thank you!
