Re: CULT: Bloomout Revisited
Laureen-
A rhizome produces only one bloomstalk. If every single fan
produces a bloom, and does not produce any more fans, it is
said to bloom out. If a clump produces new fans, but just fails
to bloom, tht is not bloomout. A fan that sends up a bloomstalk
does one of two things--it either dies, or produces new rhizomes
(fans) for the following years' bloom. The trick with rhizomes that
bloomout is suspected in is figuring out if they are just slow in
growing new rhizomes, or slow to go ahead and die :).
The old "woody" rhizomes can be put in sand and kept moist, and
often they will send up new growth. This is a good way to make
more plants quickly, and since it was going to be thrown away anyway,
is well worth the time and effort.
