When & How to Harvest Rhubarb
Rhubarb should be harvested when stalks are fully grown but still crisp and juicy. Good timing also helps protect the plant so it stays productive for future harvests.
How to tell it is ready
Stalks are usually ready when they reach about 10 to 15 inches long, depending on the variety and growing conditions. Look for firm, well-colored stalks with fully expanded leaves, but do not judge ripeness by color alone.
How to harvest
Pull stalks by grasping near the base and giving a gentle twist and tug, or cut them cleanly at the base with a knife. Remove the leaves right away and do not eat them. Leave some stalks in place so the plant keeps growing strongly.
Timing
Harvest is usually in spring and early summer, beginning once plants are established and stalks reach usable size. Pick in the cool part of the day and harvest in several rounds rather than stripping the whole plant at once. Avoid late-season heavy harvests so plants can recover.
After the harvest
Cut or pull off the leaves immediately and discard them. Keep stalks cool and dry, and refrigerate promptly for best quality. Wash just before use if possible.
Tips
Do not take all the stalks from one plant at once. Thick, fully grown stalks usually give the best harvest.
