| How do you grow double tuberose bulbs? I just planted some for more than a month now, but I see no green sprouts come out yet. Why?

|You should certainly see some growth by now. They usually begin to grow when the temperatures warm up in the spring. If you planted them too deeply, though, they may not come up. Tuberrose begonias should be planted only about 2" beneath the soil. Why not dig one up and see what's going on?
