Collin, Your idea for overpotting of pelargoniums to increase caudex size is good bacause they want to get a lot bigger than they normally become in small pots. The question I have is whether you can get a well shaped caudex or one that branches as it gets larger. Those I have seen in the ground get large but not 'bulked up'. What do you do?
