Here's my first 2 mothers in 3" pots. I'll only let them get a couple inches taller than they are now then I'll trim them back again. In theory I can get 12 in a 1ft x 1ft space.
6" tall Fat Purple....
4" tall Purple Trainwreck....
So far I've not had any problems keeping them this small. I'm still experimenting though
Sweet! That might be the way I can get going with a few more. I'll have a permanent 1x3 space for them, I guess in a 6" pot I could squeeze in 12, 8" pot would get me about 8.
If they get too big over time, I can take a clone and start again if I had to.
