|my arborvitae was turning light green;I found spider mites & sprayed. I've hosed it off a few times to keep it bug free & resprayed;I see no bugs now. We have a drainage problem there but I dug around it a bit & the soil seems all right. Yet the ends of the leaves are now turning brown. Should I dig deeper? Would bad drainage kill it? what else? The other 1 is fine on the other side of the bed.

|Poorly draining soils can cause root rot which will show up first on the tips of the branches. Now that you've taken care of the spidermites and improved the drainage the symptoms will eventually subside. It's just taking the arborvitae a little time to recover from the assaults. Just be a little more patient with it! Best wishes with your landscape!
