Rhubarb and leeks

Leeks are another cool season crop. Leeks are very sensitive to a sudden warming
trend and will set seed very quickly after overwintering ... part of their
northern heritage, perhaps? On the NW Coast we'll often get a very warm spell in
February, and the leeks will go to seed easily ARGH! 

For your warmer climate, I'd advise to try a couple of strategies:
Begin your seeds late summer/early autumn, in the coolest spot you can find,
then plant them out AFTER the heat goes out of the autumn but before first
frost. Let them overwinter. In early spring, as soon as you see some bud break
in the garden, feed them LIGHTLY with a strong nitrogen fertilizer like a bit of
blood meal. This gets them growing well & quickly. Within a couple of weeks,
feed again but still before the weather warms up -- use another nitrogen
fertilizer but one that its long lasting and less high in the N number: I used
canola seed meal mixed with a little bit of chicken manure... where you live,
cottonseed meal is a good substitute. 

The nitrogen brings them out of dormancy quickly and promotes green growth,
enhancing the biennial's natural tendency to put on a good spurt of growth prior
to seeding fruit. The 2nd dose of nitrogen promotes a slower growth, and does
the rest of the Nitrogen's job: suppresses woody growth and (most important)
blossoming/flower set. When it is an early warm spring I forego the first
feeding, and just go to the second, longer-release nitrogen-based fertilizer.
I've used it quite successfully over the years, but always watch that
late-winter/early spring weather trend so I know when to feed or withhold the
food for the leeks.

As for your rhubarb, I've never tried to grow it in a warm climate. I did,
however, find a good link that might be useful

All: I am new to the society, so excited about it all and so interested.
I live in Arkansas, spent 12 years in the UK growing rhubarb, but can't get it
to survive a summer here.  If anyone has seeds for a 'warm weather' rhubarb, or
offsets, please contact me.  I can trade hippeastrum seeds/bulbs.
(drkuonen@hotmail.com)  Also trying to manage leeks here.  Any advice from
anyone?
Don
