I have about 100 oak trees. I took the 100 oak trees out the ground and planted them into 5 gallon buckets. The trees were very healthy when i took them out the ground and about 3ft tall. I used a soil sand mix i bought at a local nursery to use to replant them in the 5 gallon bucket. After about a week the trees in the 5 gallon bucket looked as they were dying. I used a root simulator about 2 weeks in. So its now been about 2 months and the trees look almost dead. I notice at the base a sprout is coming up. What should I do altogether?
