Staking tuberous begonias
Have any of you come up with strategies for staking big, multi-stemed begonias? Last year I lost half of the plants because later in the season the bamboo stakes wouldn't support the weight of the plants and they broke off. The trouble is that with the loose soil mix one needs, the stakes bend with the plant. One site suggested cutting down those round tomato cage things and letting the plants grow through the wires. Any ideas?
