I planted red rhubarb, but it's now only green....how can I get the red color?
Polk County Nebraska
Anthocyanin is a pigment that makes the stalks of rhubarb red, with the purpose of this pigment to photosynthesize. Weather conditions, temperature variations, and a difference in moisture levels will influence how much of these pigments are produced and ultimately how red the stalks of rhubarb will be. Beyond general plant care, there is nothing that can be done to force the plant into producing more red stalks. As the season progresses, you should see more red pigmentation develop. Keep in mind the green stalks are still edible. Generally speaking, the green-stalked varieties of rhubarb are more vigorous and productive than their red-stalked counterparts.
Thanks, appreciate the quick response!
