Climate Save my Cedars!!

Designated Grumpy Old Fart
We live in the San Bernardino National Forest in Southern California at about 5,500 feet above sea level. We have mature Oaks and Cedars on our property, a little under an acre. The Oaks seem to be doing fine, they have deep tap roots, but I've just started to notice our mature Cedars are showing some browning on the outer sections of their leaves or whatever you call them. Not a lot, but enough that I'm concerned and feel the need to take some sort of action.

I know that periodic deep watering can have a major impact on protecting our Cedars during this drought period, but I want to do it correctly and not damage trees in the process. I don't want to do to much or too little. We're talking mature big arse tall Cedars, from 60 inches in diameter to over double that.

I'm looking any links, documents, anything on the "proper" and "safe" way to do this. My searches haven't turned up anything of value. Very frustrating! I have two major reasons for this. The first is to save my trees from drought stress. The second is to keep them healthy as possible and protect them as much as possible from fire. Which of course is a major concern this time of year.

I think what I want to do is put down some "Deep Drip Tubes"...well 36" deep and slow water the stressed trees several feet out from their trunks at the drip line. I think that three of these spaced around each tree and feeding them water once every week or two should get them through this rough period.

Thoughts, Links, Ideas, Suggestions?

I would contact the state extension office or forestry and ask them. I would think a 5 to 10 ft dia tree is going to take a lot of water to make a difference. Could it be diseased?

The dying cedars due to drought is becoming a problem here in Northwestern Arizona. People in the Seligman, Ashfork, Williams areas are all saying the cedars are dying.

Honestly... if they are that big, they've survived multiple human lifetimes and drought cycles. I'm not sure you could provide enough water to make much difference. But figuring out what the equivalent to an inch of rain over the area the roots extend is should give you a ballpark figure of how many gallons they'd need weekly.

The browning is a sign they are feeling the drought, but probably not a sign of impending doom.
