I have had several plants with withered lower leaves, as well as many roots that dry up. After considering the excellent replies I think that I will try smaller pots with net pots upside down in the center or Aircone pots. I have a cube of CHC already on hand. I will use it with some lava rock as a medium and get them re-potted. With a clear pot I should be able to time my watering so they don't stay wet. Thank you for the help. Ivy
