When will they bloom?
I got some unkonwn tubers from someone last winter and have this gorgeous dark burgundy foliage but no flowers yet. There is yet another leaf coming on each plant. I planted with 2 layers of Bulbtone, and just fertilized with Messenger and Mighty Plant this week for the first time. They are planted in about 20-25 gallon ceramic pots and look very healthy. How often should I fertilize going forward?
