Caring for Mini Sinningia
I have two mini sinningia, S. Dollbaby and S. Leo, purchased from Albert Buell when he still had his greenhouse in Eastford, CT. These have been in 3" pots for years and not given any special treatment. Their tubers have grown to 1-1/2"x2-1/2" and 2"x3", respectively, and are healthy-looking and rot-free. However, neither plant grows very vigorously when they are actively growing, and only sprout from one central location on each tuber. Should I simply re-pot these and give them a little more TLC when they sprout in the spring, or would dividing the tubers perhaps re-invigorate them? Are there dormant eyes on the perimeter of the tuber that would sprout if first divided? Thanks.
