Q.Why doesn’t my crinum produce more bloom?
I have it planted in a large pot with space between the bulbs, followed all Culture direction that I could find. The pot is getting dappled sun under my mesquite tree. I am not sure my three photos were sent and will try again.

Your bulb may not be getting enough sunlight. Plus the bulbs get huge. You will have to monitor your container size.
