Saguaro Is Leaning And Has Developed A Crack
At the beginning of last summer I noticed that a 10' tall saguaro in my yard had started to lean. I reduced the water to the plant and moved the drip lines further away from the base. When we returned to our home this fall we noticed that it had developed a large crack at the base of the plant. I understand that this could be from over storage of water. Is there anything besides stopping the irrigation all together that I should do about the leaning or the crack?

Unfortunately, overwatering needs to be mitigated, immediately, with a fungicide. If action isn't taken, you will start to notice symptoms like these.
Leaning might be corrected by propping it with a board, or tying it up to something sturdy.
Correcting the crack won't happen. What you will have to do, though, is to control the bacteria that will take that spot over.
