We planted 7 cypress trees this past weekend (they were in 15gal pots and about 4-5 ft tall) and on few of them some of the lower branches started to droop. I'm not sure if it's simply because of rough handling at the time of planting or something else. They did all look OK when we bought them. Unfortunately they were all left out in the pot in the sun (hot and dry So.Cal.) for about 6 days after purchasing them, which I now do realize was a mistake (although that's how they were sitting in the nursery, too) Could that have caused anything irreversible?
Also this morning I did a more thorough check on them and almost all of them have tiny spiderweb things mostly around the top, likely indicating spider mites.
I do hope there are some steps I can take from this point on to maximize the chances of recovery. Can someone give me a "to-do" and "not-to-do" list please?
