Hedychiums - flowering too fast?
When I bought my Hedychium Coronariums (white), the flowerheads were about the size of a medium-sized lemon when they started to bloom, the blooming continued for a week or more as the head put out more and more flowers.
After a couple of weeks of inactivity, they've bloomed again as some of the younger canes have grown up. However, this time the flowerheads were quite small when they started to flower, about the size of big thumb. They put out about 6 blooms or so over a period of a couple of days, and then stopped. Oh dear!
They get plenty of sun and water, the leaves look fine, not burned or anything, so I don't think they're getting too much sun. I haven't given them any fertiliser yet.
Does anyone know why they bloom in this manner? I'd love to get them to bloom as abundantly as they did when I'd first got them.
I'd greatly appreciate any advice y'all can give,
Thanks and regards
