Have a kolanchoe blossfeldiana bought in full bloom. Lasted bloom for 6 months. Cut it back to 4" stalks (3) in 6 " pot. Growing it in artificial light. Tops of stalks which are 1/2" wide are filling out. But nothing in middle or bottom of stalks. Is this correct? 3 stalks too much for 6" pot? Recently re-potted to this new pot. Like these plants because they hold their bloom soo long.
Thanks
