Hi Chuck,
Thanks for the info.  SDBs peak around mid March (later this year) TBs peak around the third week in April.  Is that less then up there?
Thanks again for the insight.
Best regards

An interesting piece of information. Definatly climatic. I havn't
noticed any bloomout on SDB in my climate. Actually I don't get much
bloomout but when I do it is on larger plants, TBs and occasionally an
IB. Usually if I just leave rhizome alone, it will put up something
next spring. It is odd having a rhizome sit througth the season with
no foliage and come back to life the next year.

I have a couple of suspicion of that what happens that might cause

One is that the longer growing season that you have results in a lot of
mature plants by the time the weather is cold enough to initiate buds.
Thus all the rhizomes bloom in spring.

The other possibility is that the plants start groing actively in
spring before there is long enough daylight to initiate flower bud
growth. Thus all the daughter rhizomes have grown too much to respond
to bio-chemical inhibitors from dominant mother rhizome.

When do SDB and TB peak for you? I'm wondering about time between the
two peaks. I suspect it is much less then what we get in Ontario Canada

Hey Griff (and everyone else) it seems like SDBs and MDBs
are much more prone to bloomout here. We usually don't have too many
TB bloomouts but many in the SDBs. Has anyone else noticed this or is
just climatic?
