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.
John from Maryland sends along a photo of his blooming Stapelia and a very nice Echinopsis hybrid.
I just wanted to say hi, and share a couple of photos of my plants with you. I came across your site a while ago and check your blog often. I live in Salisbury Maryland…all the way across the country.
I have a lot of cactuses and succulents. We cannot grow many of them in the ground here (except some prickly pears) so I have to bring them in and out each summer.
Anyway, attached are 2 photos – the first is my favorite cactus. I cannot help but laugh at its beautiful shape. The second is a Stapelia gigantea. It had one flower so far this year. The flower was about 15 inches across and very stinky.
I love your blog. Next time I’m out that way, I’ll come into your shop.
Well obviously you can plant cactus and succulents in your front yard to reduce your watering. Why else are you re4ading my blog? Cactus are also the future of desert-grown food supplies. Well you knew that already too, anyway. But now IO9, the sci-fi website, wants you to know that Cactus may be the future of bio-fuels. Who knew!?!
As drought strikes broad regions of the world, farmers are focusing on the crops that can feed people—not the crops that can power their cars. But what if there was an energy crop that could grow where traditional crops can’t? Even in a drought? Enter the cactus.
The prickly pear cactus is one of the more common cacti in our world. It’s also a member of a unique group of plants that use an unusual photosynthesis pathway that evolved due to extreme growing conditions, in arid climates with long, hot, dry days and cool nights….
CAM plants have a special way of going about the business of photosynthesis: They only absorb carbon dioxide when it’s cool out, which means they don’t lose as much moisture as they would during the sunny, hot daylight hours. Then, when the sun comes up, they close their stomata—their pores….
Though there’s plenty of research to be done on how these plants would do as bioenergy fuel, Mason and his co-authors suggest that prickly pear could help make biogas—or gas which is made when organic matter is broken down without oxygen—along with other forms of bioenergy like bioethanol.
We get press releases! So we can heartily recommend a visit to Santa Monica, where I used to go to school, and while you’re there there’s a Happy Cactus! Also, don’t forget to visit Abbott Kinney in Venice.
I’ve attached a photo of a new piece coming to Daniel Rolnik Gallery by Tripper Dungan of a happy cactus. It would be epic if you could share it on your blog. The show, “Pacific & Northwest” opens on July 18th.
