Pseudolithos cubiformis, 4 years + 4 months old

I wanted to check the roots on my Pseudolithos cubiformis to make sure they were doing okay. A couple of months ago the roots were almost dead and the plant was shriveling up. I don’t know exactly what happened, so I just dipped the roots and the base of the plant in rooting gel, put it back in its pot under grow lights and hoped for the best. It seems to have worked! Not only have the roots started to grow back, but the Pseudolithos has started a growth spurt. It even looks like a flower bud is forming as well.

Right now it’s just about 5 cm wide from one corner to the opposite one. I’m so happy right now! My Pseudolithos is my most precious plant, and it may also be the most valuable plant in my collection.

Pseudolithos migiurtinus and P. cubiformis, 3 months old

4 Pseudolithos seedlings are still alive. I planted some of them together to save space and they didn’t seem to mind being carefully repotted anyway. One of them is a Pseudolithos cubiformis (top right in the first photo) and the rest are P. migiurtinus.
The little bubbles have started to show on top of most of the seedlings. It will be a while before they’re completely covered in frog-like skin, but right now they’re so cute!

Pseudolithos migiurtinus and cubiformis, barely 2 months old

Look how adorable they are now! A couple more Pseudolithos migiurtinus seedlings have germinated since I last took a picture of them. Now I’m up to 2 P. cubiformis and 4 P. migiurtinus seedlings. Unfortunately, the sickly migiurtinus died.
I took a chance and repotted the two biggest plants. If anything goes wrong with the community pot, these two babies will be safe and away from mold/damping off etc. A 5 cm pot will be the perfect home for at least 4-5 years.
Right now, they’re all still living in my mini greenhouse under grow lights. They seem to be doing okay for now, but I will probably have to move them to my south facing window eventually.

Pseudolithos cubiformis, 4 years old

This Pseudolithos cubiformis hasn’t grown at all since.. I think.. 2018. I just wanted to take another photo of it to show that it’s still very much alive. I considered shoving it under the grow lights with my small seedlings, but it might be too much of a risk to change its environment now. I mean.. this incredibly sensitive plant has survived 3 years in this South facing window, probably because it likes it. Why it stopped growing will probably have to stay a mystery.

Growing Pseudolithos cubiformis from seeds

I made a little care/germination guide, now that I know what I’m doing. I hope this helps.

If you’re interested, heres a link to a collection of blog posts about my Pseudolithos seedlings from germination to the latest post.

Pseudolithos from seeds:
Finding P. cubiformis seeds is probably the hardest part. P. migiurtinus and P. eyelensis are easier to find, but it’s still a bit of a challenge. Koehres in Germany and eBay may be your
best bet. Never buy seeds from China.

I was able to germinate all of the 5 seeds I bought. I placed the seeds on top of some moistened diatomaceous earth cat litter (pumice, crushed lava rock or turface is impossible to find here, so I used the next best thing) and used the baggie method to keep everything moist in there. I placed the bags in an eastern window (grow lights work as well) and the seeds germinated one by one over a period of 1 month.
Now, keeping the seedlings alive is a hit and miss. I took my seedlings out of the bag a week after germination and kept them moist for the first couple of weeks. Then i experimented with letting them dry out for a couple of days before watering again. Some seedlings grew very fast and some stalled and died over the first 5 months, so I put it down to luck.

Pseudolithos care:
Soil
I still use pure diatomaceous earth cat litter as soil for my adult plants. Again, pumice, crushed lava rock or turface would be perfect. Never use peat for these unless you live in an arid climate. It’s much easier to manage watering when you know that the soil dries out quickly instead of staying wet for a week.

Watering
In summer I water mine approx. every 2 weeks depending on how much sun they get and how long the soil has been completely dry. In winter I water once every 3 weeks-1 month.
Because I don’t use peat, I add quarter strength indoor plant fertilizer to my water once every 2 months. A small pot with drainage holes is a must.

Lighting
My plants are in a south-facing window with 7-8 hours of direct/filtered sunlight. Always indoors, even in summer with temps around 20-30 degrees C.

I’ve seen people use fans, thermometers, hygrometers and expensive lighting setups to keep their Pseudolithos under 100% controlled conditions, but I’d say unless you have inadequate lighting in your house, that stuff isn’t necessary.
