When was the last time you repotted? You may need to refresh the soil. Be sure your plant pot and soil has good drainage. I put some orginary gravel in the bottom of the plant pot to ensure good drainage, when I plant in dirt. I now use lava rock and clay gravel to grow my moms as it is easier to maintain. I don't F&D my moms; I use electronic valves, a pump and a timer(s) to water my moms and I plant them in a catch trough from a disgarded constant flow system. At least I found a realistic use for this thing. It came with an attached resivoir. I cheated and put about an inch of ordinary gravel in the trough before I added the lava rock and clay gravel. The total depth of the rock is eight inches.
