Last year my begonias were half a success, this year I'm having another go.
I bought 4 healthy large plugs from the GC. They have been repotted and sitting on a gravel tray in the GH. The pot is moist and I keep the leaves dry, but still they manage to droop and fall off. I'm left with one stump and three sparsely leaved begonia plants.
What am I doing wrong!
