Organ Pipe Cactus

One of the arms of my in ground cactus is getting tall (10 feet) and is hitting the wall of our house. Can I cut it in half and plant the limb for a new cactus? If so, what is the best way to do it?

What Are Guidelines for Trimming Organ Pipe Cactus

What are the steps for trimming an Organ Pipe cactus?

ANSWERS
AnnsGreeneHaus

This cactus is very slow growing, but can reach a 10 foot diameter in 150 years. If it has been planted too close to it's neighbor, someone didn't take later growth into consideration.
To trim an arm, (branch) on this cactus, you should use a very sharp saw and cut as close to the base of the plant as possible.
If you are asking about trimming the entire plant, this is what I would suggest. If the plant is too tall, and there is a subspecies that grows to only 10' tall, take out the tallest arms. DO NOT saw off the arms to shorten the plant. The plant will initiate new growth at the injury site. The new growth will be too heavy and weigh the arm down, causing more injury, or an unsightly appearance.

This is likely Scale pests.

They can be scraped away from the plant.

Neem Oil can also be used to treat Scale.

A Mature Organ Pipe Cactus Where Limbs Are Starting to Fall Over

I have a mature old organ pipe cactus and in this last year many of the limbs are starting to fall over. Was wondering what can I do in this case? Is it normal for them to do this? Or do I have a problem such as over or under watering? thanks!

This actually sounds like a case of over-watering. These are very drought tolerant, and will not tolerate "wet feet" for very long. I would let the potting material dry out pretty well in between waterings. You might apply a few drops of rosemary oil in the water for the next watering, just in case an infection is trying to start in.

My organ pipe cactus has a problem on one arm
See photo.
Where is wrong and how do I fix it?
Thank you.

ANSWERS

It looks like it has sustained damage at one time. If this spot doesn't spread, then it will not harm the cactus. If it is spreading, then it could be an infection. If this is the case, then I would recommend applying peroxide to the wound. Also use some wettable sulfur around the base according to the instructions on the package.
