Care and maintenance of barclaya longifolia?
Hi. The subject pretty much capsulizes my question.
I've go a couple b. longifolia that I bought as bulbs (or tubers,
whatever). They grew into beautiful, delicate plants, spread out a lot
and are busily trying to bloom.
So far they have put seven buds up on stalks - one got above the surface,
and the rest stopped below it. None of the buds have opened. They start
to open, then stop developing. What do I need to do to get them to open?
Do they need to go entirely above the surface to bloom? Is there a limit
to how high the stalks can reach? Mine are in 15 inches of water.
The plants have put a lot of energy into putting up the flower stalks and
in the mean time some of the older leaves are dropping. Is this normal?
Can I expect the plants to go dormant after a while? If so, will it be
necessary to take the tubers out and give them a resting period, or will
they do it on their own?
