Sulcorebutia rauschii, the purple, spineless cactus

Look how much my Sulcorebutia rauschii has grown in 2 months! This pot will be too small for it very soon. I feel like this cactus grows like weeds in a lawn.
This one is perfect for the impatient cactus lover. It seems like it grows faster than many other types of cactus (at least after they reach a certain size). Each pup grows a set of babies, which then grow another set of babies etc. Eventually you will have a giant pot of purple bulbs in your garden.
I didn’t get any flowers on my Sulcorebutia this year. Technically, it can still happen, but right now is the time to be careful about watering the outdoor cacti. I wouldn’t want these guys to rot.

The Sulcorebutia rauschii exploded with growth

Maybe it was the new pot or maybe it happened because I started to fertilize. But the Sulcorebutia rauschii exploded with growth in spring and especially here in summer.
I love this one because of its color and because they grow in big clusters, filling out the entire pot in no time. A couple of years ago I saw one in a garden center labeled as “rare cactus”. The cluster was just about the size of mine and it cost DKK 300 ($40). I bought mine as a mini-plant with only one head for DKK 25 ($3) in 2017. I’m glad I didn’t buy it back when I first saw it.

Repotting day!

It’s repotting day for my cactus seedlings, Gymnocalycium mihanovichii and Sulcorebutia rauschii. My cactus seedlings and the Sulcorebutia should have been repotted a long time ago, even though they seem to be thriving in their way too small pots.

I chose to keep the three biggest cactus seedlings and send the rest off towards someone who might want to adopt them. All of them have been potted in pure Diatomaceous earth cat litter with no potting soil. That way, they’re easy to repot next time, and there’s very little reason to worry about root rot and overwatering.

Just gotta say.. when you mess with spiny cacti, remember to wear gloves or use a tong. Not just your hands. Let’s just say it’s very difficult and painful to remove broken cactus spines from the soft skin under your nails.

Repotting time for my fast growing cacti

Had to save my Sulcorebutia rauschii and Gymnocalycium mihanovichii from being squished by my now giant Mammillaria spinosissima “un pico” (phew, scientific names are hard). They were all planted in one pot, but that didn’t work very well. I’ve never seen a cactus grow that fast.
On the bright side, the Sulcorebutia and Gymnocalycium are doing great. One is growing multiple pups and the other is flowering soon.
