Thanks Fluffy! Everything is doing quite well, with one exception. That pot in the foreground left in the second photo. It was a beautiful blue green all summer and then start yellowing out of nowhere. I unpotted it and it was pot bound sideways, not down. But the roots were growing into the pot, no dirt, just a mess. I didn't have a shallow pot so it's been repotted in that pot there. It's starting to grow blue green again so I think it's ok. I need to find a shallow wide pot. It's a Sedum, Himalayan Skies. And it really belongs in the garden where it can creep like a carpet.
I love your Gymnos too, I'm just fascinated with all the varieties. Mine is a Gymnocalycium saglionis. I just love it to pieces, one of my favorite plants!
I have since learned that if you repot every few years, fertilizer is not needed in cacti. They like poor soils. I had used a fertilizer for succulents and cacti but it had too much nitrogen. Too much nitro makes them grow fast and etiolated. I had fertilized my Rebutia after she put out 30 blooms! I was trying to help her but she grew weird. But she's ok and grew pups too. She's flawless and healthy! I couple others got a bit etiolated a bit after fertilizing, so never again with that stuff!
Yep, Euphorbia ferox! I love this too and along with the Euphorbia obesa, I love Euphorbias! The Obesa is STILL flowering, she's gone all summer! She's still a nice green color (the photo makes her appear to have yellow along the bottom but that's false). She is still spotless as well!
Sometimes plants spend their summers working on their roots instead of growing larger. I have a few that didn't do much this year either and I even unpotted a couple and Holy Crow, their root systems got huge since last year! I was going to reduce the size of their pots, but no way, they are stuffed in their pots already! So I wouldn't be too quick to fertilize, don't force them. I believe they will grow when conditions are right to do so. Some species are fast growers, others grow at glacial speeds. If I find a good fertilizer, I will let you know, but I think I'm just going to repot them with new dirt every couple years instead. I'm leary of fertilizer now.
