I have a Thyrsifolia Kalanchoe (pancake leaves) which I have chosen to keep in a pot rather than plant in the ground. It is in a 15" high pot. The bottom 6" is filled with fine beach sand and the top 9" is filled with potting soil. Am I right in assuming that because the sand in underneath, it won't adversely affect the plant or will the sand affect the roots?
I realize I am quite late in responding to this thread, however, this method of placing sand in the bottom of a pot with potting soil in the top portion is no longer recommended. It can create a perched water table where the water will stay in the potting soil until the saturation level is reached to go into the sand. This could create a deficit of oxygen to the roots. Better to have the appropriate potting medium the same throughout the pot.
This plant is a succulent,
Kalanchoe thyrsifolia, so I would have used a specific potting blend suited for these special plants.
An obvious question, but I will ask it anyway...you do have a drain hole in this pot, correct?
