Two years ago we had straight line winds one day and two day later a tornado, lost 6 trees and a garage. So last year the garage was rebuilt so heavy equipment was used to excavate an area to rebuild and so forth. So I have a southern red oak that was close to all the excavation, one side was covered with red clay and some compaction. So to prevent any more damage and keep the tree healthy I like to get some advice. The ph is 6.5, P pound per acre is 99, K pound per acre is 226, Ca is 4221, and Mg is 398. P & K is high, Ca and Mg is sufficient.
