How to Water a Cactus in Nevada
The Las Vegas R-J gets questions.
Q: I bought a Mission cactus last year. The tag said to water it well until it “was established,” but I didn’t really know how much water to give it after that. I looked up Mission cactus on the Internet and most sites said little or no water, or arid dry. It has grown quite a bit since I planted it, and even now has small new growth on a few ends. Lately though it has twists and folds with a yellowish color in the middle of the “hands.” I have no idea whether I am watering it enough or too much as it doesn’t respond much differently. I really like this plant, and it is a focal point when anyone comes through our gate into the courtyard.
