Growing in pots
I'm sure that most members here are growing thir Sans. in pots, as I must in Zone 6 (New Jersey). I've been wondering about the proper pot size to use. I know that my S. trifasciata and laurentii can stay pretty crowded in an azalea pot, but some of my plants get pretty heavy rhizomes, and seem to want to spread out a little bit more (like my S. masoniana in a 10" pot with 15 leaves, or S. cylindica, or even S. hallii). I've always been heasitant to put sans in very large pots because I am afraid of watering problems - especially in the winter. I also really don't want to divide them, as I am just starting to get mature growth patterns on some of these plants, and I think dividing them will keep them juvinile.
Anyone have any suggestions?
