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.

Selenicereus grandiflorus, 3 months old

My Selenicereus seedlings had a bit of an accident and I lost most of them. White mold got in and killed off the roots on my babies, and these are all I have left. At least they look somewhat healthy. Especially the one in the middle!
Right now they’re growing on my window sill and not under grow lights. The airflow here is better, but it’s slightly colder. Hopefully they survive the colder air in winter.

A much needed pot upgrade for my Mammillaria spinosissima “un pico”

I finally had the guts to upgrade the pot for my Mammillaria spinosissima “un pico”. This thing is very prickly! You know your cactus needs a pot upgrade when you give it a ton of water and the pot is bone dry the next day. Apparently my dear Mammillaria was very root bound. The root ball was perfectly intact when I removed it from its old pot.
The first thing I did was to carefully loosen the roots and remove as much soil as I could, especially near the soil line. This makes the cactus very unstable when you repot into fresh soil, but it also allows water to actually penetrate the root ball. This is the first thing I do when I buy a new cactus, as well.

It looks so much happier now! The size of the new pot makes it look so small.

Mammillaria plumosa, 3,5 years old

These seed grown 3,5 years old Mammillaria plumosa are now bigger than my hand. They’re currently staying in a 15 cm pot, but it won’t be long before they need an even bigger pot. This is the fastest growing cactus I have ever grown from seeds. There are actually two plants in there. The big bulb on the second picture (top right near the white string hanging from the wall) is the brother of the big mass that turned out to be the faster growing seedling.
I wonder how big this plant is going to get.

Selenicereus grandiflorus babies!

I found these seed packets with Stapelia gigantea and Selenicereus grandiflorus a month ago and decided to give it a try. I don’t think the Stapelia seeds will germinate, because I couldn’t keep the seeds from being overtaken by black mold, even after a good hydrogen peroxide soak. The Selenicereus grandiflorus are doing okay right now. A month after germination, a couple of them have grown these little spikes and they’re adorable!
Selenicereus grandiflorus are known for their huge, beautiful flowers, but the plants themselves can be kind of bland. This is why I love cacti, though. They can blend in with the background, sometimes even be downright ugly for years, but when they finally decide to bloom, they’re magnificent. Even if the flower only lasts for one day.

Astrophytum coahuilense x ornatum, 2 months old

Look how adorable my little CO x OR hybrids are today! They’re like little fluffy stars.

I recently took them out of the little greenhouse, I kept them in. Some of the old seed shells started to grow some sort of white fungus, which would have killed the nearby seedlings very quickly if I hadn’t removed the top of the greenhouse. Astrophytum seedlings are notorious for dying from damping off, so maybe it was about time I introduced them to lower humidity.

Right now I keep the soil from drying out by watering a couple of times a week. They’re still under grow lights and probably will be until next spring. They’re still way too small to experience the late summer sun.

Hildewintera colademononis flowers!

I’ve been waiting for my Hildewintera colademononis to bloom since 2017 when I bought them as small unrooted cuttings. When I bought them, each of the cuttings were no larger than a pinky.
I really like this cactus, probably even more than most of my other cacti. I’m just a really big fan of hanging plants, especially when they don’t have to be grown indoors to thrive.
This Hildewintera loves whatever you throw at it. It loves a good amount of water in summer and also to be kept completely dry in winter. It does stretch if it’s placed in less than ideal lighting and it can burn if given too much direct sun. The placement I chose for it on my balcony seems to be perfect, with direct afternoon sun and indirect light the rest of the day in summer. In winter, when the sun hangs lower in the sky, it gets (weak) direct light all day.
