Hello,  
We live in Rocklin, CA. In the backyard there are 4 redwood trees. One of them has had trouble every summer (this is our 3rd summer here.) The top of the tree looks great, but from about 10 feet up down to the lowest branches on the West side the needles are drying up and falling off, in the past it has looked much worse, but I am concerned that it is continuing to happen. Each summer it happens all around the tree, but is always concentrated on the west side. Our neighbors have the same trees and have no had any of the trouble we have had. We have a drip system for watering: 2GPH with 4 drip heads for 2 hours 3x per day. All of the other trees are tied into this system and are doing great. We do get very hot weather here which is why we water them so much. Our soil is very rocky and does not drain well. Any advise would be much appreciated.

Hi Jessica, thanks for the question. I want to direct you to the Master Gardener program in your county. They would be your best resource for region specific advice.  
You can find them on their website - http://pcmg.ucanr.org/Got_Questions/  
Or you can reach their help line at 530-889-7388.  
Best of luck!
