you guys helped me earlier so here's another problem. i just did a large install. in which i planted two (3 1/2" trunk diameter) bradford pears. One white cascade crab, and one prairie fire crab. They were all transported by me and tarped in drive. All were planted same day and were in good shape then. We'll now one week later they are all wilting BADLY. The soil was about 6" of dirt then clay. There has been a decent amout of rain and the root balls are still very damp WHATS GOING ON!
