It may be advisable to suspend or reduce fertilizing during the latter parts of the growing season for some hybrids since they show a tendency to split along the groove between the plant s ribs at this time. In southern California, splitting can begin in August or later, but as early as July for some hybrids. Another possible solution to the problem is to use a quick-draining potting mix for such hybrids, as mentioned above. The great majority of the hybrids readily develop pups, some very freely. If you find this exuberance undesirable, simply snap off the pups when they are tiny and discard the little critters.
Young pups detach quite easily and without visible damage to the plant.
I prefer leaving a few at the plant s base and permitting them to grow. The plant will appear more handsome with the pups and a greater number of flowers will eventually be produced when the pups reach flowering size. There is also the possibility that their retention will help discourage further undesirable pupping.
