I ordered two reg and 'rosea' from Kartuz this year and want to pot them. I know they can get big- what size pot would be good- I'm thinking 12in. Is that big enough? I'm in La. if that makes a difference.
You dont want to over pot them ... work your way up like any other plant. My biggest one is in a 15 inch but it took a few years before it got to that stage and has been in that pot for a few years. In the wild they are known to get to nearly 10 ft but mine are only about 3ft. I have about 5 different forms and each one is different plus one hybrid. They are all pretty plants that bloom in the winter. These are not cold hardy plant btw so you will have to bring them in for the winter. If you have a cool shady spot in the summer that would be ideal.
Ok- so I will scale the pot size back. Also, do they need to be pinched? They are still in the pots that they came in and single stemmed. However, I noticed today that there are shoots starting at the nodes- should I just leave them alone?
