l've heard that the longer the caudex stays under the soil the faster they grow. Then raise the caudex when you get the size you want. They'll still grow above the soil, but not as fast. I don't know if this is true or not.
This doesn't apply to all caudiciforms. More towards the ones that start underground.
Fockea edulis and F. crispa are better left under the soil until they get larger.
I want to buy a young Fockea and plant it with some stones in the pot to see if the caudex would develope some contours. Hopefully to have an unusually shaped caudex years later.
