I have some Sinningias I grew from seed (sown last May). They really did great and I have several varieties. These are not the miniature type. Some of them are really floppy. I was afraid to use sticks to prop them up for fear of damaging the developing tuber. Should I worry about this, or just let them flop over their pots? Some seem pretty spindly and leggy. Others are developing stronger main stems. I am really pleased with them, I am a newbie though, so didn't know if some are just naturally floppy. Thanks for any input.
