When can I start harvesting newly planted rhubarb?
After planting rhubarb, it’s best to wait 2 years (growing seasons) before harvesting any stalks. The two year establishment period allows the plants to become strong and productive.
Rhubarb can be harvested over a 4 week period in the third year. In the fourth and succeeding years, stalks can be harvested for 8 to 10 weeks.
