Checking temp requirements for rhubarb indicates that winters need to be below 40F for meeting required chill hours. The almanac says:
"Rhubarb does best where the average temperature falls below 40ºF in the winter and below 75ºF in the summer."
Another site says:
"Ideal temperatures for growing rhubarb successfully are below 40 ° F, (5 ° C), in winter, and temperatures averaging less than 75 ° F (24 ° C) in the spring and summer months."
And a third says:
"...in
really hot climes, rhubarb must be grown as an annual crop, planted fresh each year. Hot-weather rhubarb fiends start their seeds indoors (just like
tomatoes) in August, transplant the starts outdoors at eight weeks of age into fertile, well-drained soil and harvest stalks December through April—after which the poor plants just burn up in the heat. "
It's gonna be fun trying!
I started three pots last night, 2 seeds to the pot after giving them a requisite two hour soak in water. Off we go!
