Are Uebelmannia difficult to grow? I would like to get one but don't want to spend the money if they are difficult to grow.

Wow, I had to look that one up....I want one!!!!!

Don't know anything about them. Will let you know if I discover anything.

So I found this:

Cultivation: Not easy; it has a large root and lives among rocks. This tropical cactus prefers loves warm, moist, humid conditions, and mist spraying is a must in summer. Water regularly during the growing season and use a very draining mineral potting substrate. At the onset of winter, do not water. Uebelmannias need heat all year round, and extra winter heat; minimum 10°C is best. Avoid any frost. Keep cool in summer. This plant proves to be root prone if kept too cold in winter. To help stop this, a good deep collar of pumice or lava grit is an excellent idea. It prefers a full sun position and possibly afternoon shade in summer. If you can place it so that this occurs, the plant will be much happier.

Propagation: By seeds. Germinating seeds can also be tricky. But plants are often grafted making them easier to grow, particularly through the winter. If possible, using a rootstock that is hardier than the Uebelmannia is the ideal.

Seems like finding a grafted one would be the safest bet!

Thank you for the info. The humid conditions and 'keep cool in summer' count me out. I won't slave over a plant by misting it every day and stuff like that.

lol, i don't think it really is necessary to mist it every day, unless you want a show specimen

'Keep cool in summer' is definitely out, though. For example, they are calling for 98F today. I think that's around 37C if I did my calculations correctly.
