I know nothing about redwoods but with any other tree, you water when the tree needs water. That means checking the soil down a few inches to see how dry it is.

Make sure that that pot has drainage holes. Most trees do not like to 'sit' in water very long.

The dog pee can be washed off when you see it happen and by now should not be a problem.

I wouldn't use any fertilizer or anything else in the water at this time.

Someone more knowledgeable with Reds should come along with some expertise on the subject.

your not thinking in tree time ..

the damage could have been done.. when he was over watering .... and its just now showing

Seems to be overpotted. This can cause water to be "perched" at the core and keep the roots too moist.

This is a coastal tree. Tough to grow in Sacramento.

So is there any thing I can do to save it? It seems overwatered is the consensus? Smaller pot?

I know people have grown this tree in Sacramento. It's hot but we do have water here.
