My Saguaro is a least 200 years old with 6 arms and a few offshoots. Recently, the entire base of the tree up to the arms seems to have lost its outer skin and is brown in color. Am I losing this tree or is this normal?
As far as I know, this is not normal. The plant is very old and may simply be dying from plain old age. But I would encourage you to contact your local extension service and discuss this with them. They may have information on how to save this beautiful plant. Here is the contact information for your local office: https://extension.arizona.edu/maricopa
I have a mature saguaro that has a large arm damaging the roof of my home. Is it permitted to cut the 1 arm off and will it permanently harm the plant? I own the property and the cactus has been here since I took ownership. I don't want to do anything wrong or damage the plant.
Do to the protected nature of the Saguaro Cactus, I would encourage you to contact a professional.
The size and age of your plant may have special considerations for pruning.
Saguaro Cactus are one of the few cactus that will not root from cuttings, so replanting the pruned arm is not possible.

Saguaro arm dropped of cactus. Is it possible to replant the arm? What steps would be necessary to do so? This arm is quite large measures four feet has been detached for and on the ground for about one month?
The broken end should have been cut and dipped or rooting hormone applied before allowing the end to scar over.
This will help from rot setting in.
You could still try applying rooting hormone to the end before placing it in a cactus mix and wait and see.
If successful it will take some time.
I have a very old Saguaro that is leaning south so much I am afraid it may fall over. It is close to 20-25' tall. I live in Green Valley AZ. Is there anyone who could come out and access the situation? Any way to prop it up or re-plant it? Thanks so much My camera batteries are dead, so I'll have pictures in about an hour. 720pm now on the 19th of April 2016
I would contact your local County Extension Office and inquire if they have any local experts that can examine the cactus for you.

I have four Saguaros in my yard in various stages of maturity ranging from a large one that has been flowering for years to a small one that has some previous freeze damage and is very slow growing. All except the small appear to be very healthy. We live in NW Las Vegas, NV. My question pertains to the infrequent periods normally not exceeding a couple of weeks where the winter temperature gets into the 30 degree area. Should I cover the plants with burlap as a precaution?
Saguaros are supposed to be able to tolerate brief temperatures as low as 14 degrees F. Some experts warn against wrapping saguaros in burlap, because in wet weather it can trap water against the cactus and cause rot. A better protection method is to cover the tips of the arms with a styrofoam cup or similar, since they are the most easily damaged.
Saguaro cactus grown in a garden pot for approx. 25 yrs. Provides white blooms yearly. Seems healthy. Now it has a round red bulb growing on its side which is a new development. It does not resemble a bloom. Any suggestions as to what this could be? I cannot put a picture on the internet to display the cactus. It is a lovely plant and I would like to repot it into a larger container. It is probably close to 10 ft. tall.
This sounds like the bloom was pollinated. This will lead to a red fruit, where the seeds will be located. There is nothing that needs to be done, as this is part of the natural life cycle.

I bought a saguaro while I was in Az last month. It came with two cacti, one larger and obviously more healthy than the other. I repotted them separately and gave the healthy one to my mother. Hers is doing fine. The little one was gray and shrively, so I watered it. Now it is soft and losing the little nubs that have the spines on them. I wonder if FungiCure spray would help, if I spray the roots before repotting it to dry soil? It has a nice, large root bunch, just the top is all squishy. Help? I don't want to let this treasure die! Thank you!
It sounds like it is far beyond repair. You can attempt the spray, but if it is gray and mushy, then it is probably on its way out. Just make sure, in the future, that the cactus is allowed to dry out between waterings. This will prevent fungal infections.
