|when do you harvest rhubarb? my stalks dont seem to ever turn red, remain green...|
|That may be the variety as some are greener than others. Start harvesting the year after planting in early spring when the stalks are 12 to 18 inches long and leaves completely unfold to a flat surface. If a seed stalk forms in the midst of the plant, cut it off to extend the harvest season.
When the plants are established (after 3 years), the harvest period should run 8 to 10 weeks, or until the stalks become thin, a sign that the plants' food reserves are low.
At least one third of the stalks should be left on the plant after the harvest.
The petioles (leafstalks) are edible; the leaves are poisonous.
