Does anybody have any idea if there are growing conditions that affect
fertility in hippeastrums? I am aware that many perennials initiate
blooming better under stress than when well nourished so I don't fertilize
or water them much before buds appear. But does a similar effect affect
capsule abortion?
I often see the capsules begin to enlarge and then shrivel up and I wonder
if I didn't fertilize them if the same thing would happen. Right now I'm
seeing about 85% of hand pollinated ovaries begin to enlarge but only about
10% continue to maturity, Any ideas?
Thanks
Tim
