My Cattleya's won't bloom
Hello:
I have 3 cattleya"s that are blooming size and I cannot get them to bloom. I fertalize weekly at 1/2 strength. I give them as much sun short of burning. I water well. etc.
So I am wondering if my grow lights in the fall/winter are the problem.
I put them under grow lights 12 hours a day from October- April. Do I need to fine tune the lights to the natural winter day length? I simply cannot figure of what the problem is. They are healthy and thriving other than blooming.
Should I try to cut back on winter light? The species I have bloom in late winter, early spring.
Thanks
