I know that I planted some sinningias deeper to get some roots on the multiple stems. I not only got roots, I got multiple bulbs. The stems increased above the original bulb to form additional bulbs (properly tubers) at the correct depth for the plant. I removed the secondary tubers and planted them seperately. And since, the original tuber has sprouted again. So, I can get multiple plants from 1. I am very excited about this. ===== John Ingram in L.A., CA.
