I have two Caladiums in my bed room in little teracota pots. They are doing very good but the leaves tend to grow to big and cause the stem to fall over. I have them tied but doing it to much bunches the leaves together and makes it ugly. So today i just cut the huge sagging stem off because there is plenty of new growth to compensate. i was just wondering if i was doing the right thing... and am doing anything wrong that would cause the stems to be weak?
