Managing a Deep Crack in a Pseudopilocereus Cactus After Shipping

A 2.5-foot Pseudopilocereus arrived from Arizona with one of three stems cracked 3/4 through, 7" up. Risk of rot is high. Best: cut at the joint or 1–2" below break with sterilized knife, fungicide on cut. Start new plant from the cutting (cut 2" above break, fungicide, callous, root). Alternative: pack fungicide into crack, monitor for mush/yellowing—risky. If it were mine: cut at base for aesthetics, then cut above break for a cutting. Small arms may sprout at base cut.
