My cane-stemmed Begonia flowers are falling off and there is little sign of any new growth. It is two stemmed - about 6 foot tall and in a 12 inch pot. Up until recently was showing great flowers and very healthy looking. No new growth appearing at the base - few new leaves beginning to show but looking stringy. Any help please ??
Hi Graham, I have the same problem. Mine is in the ground and in shade house.I believe the answer may be to much water in my case. They don"t need a lot of water.
