I live in kansas city and was gifted this beauty for mothers day.. I want to take the best care possible of this gorgeous cactus! Our home has tons of natural light and we were told by the nursery we purchased it from that the spot we have it in is a good one even though it doesn’t received direct sun. I’m terrified of under/over watering. With a plant this size, how often should I be watering , and when I do, how much should I give? Do I fertilize? It’s about 8 ft tall. Thank you for your expertise.. Love your blog!
That’s quite large! In general I would recommend some direcgt sun, though these Euphorbias can sometimes handle a bright room with no direct light, but it’s tricky.
Basically, with lower light levels you want to water less. A lot less. I would try starting with watering every 2 months – try to soak the soil as much as possible without the plant sitting in water. I would fertilize just a little bit once per year in the spring. You want to slow down its growth so it doesn’t grow more than 2 or 3 inches in a year.
However it would be best if you can move it to where it gets some directct sun and then you can water more often.
