Growing Rhubarb in Buffalo

Buffalo's Zone 6a climate on the eastern end of Lake Erie is famously influenced by lake-effect weather — heavy winter snows but also a moderated spring and fall. The frost-free window is about 161 days, among the shorter in this list. However, summer temperatures are comfortably warm for tomatoes and peppers when they finally arrive. Short-season varieties and indoor starting in early April are critical strategies.

In Buffalo (last frost around May 3), rhubarb can go out around April — approximately 2 weeks before the last expected frost, making it an early-season opportunity.

Rhubarb thrives between 40°F and 75°F. It tolerates temperatures as low as 20°F, making it a candidate for early spring planting before the last frost date. Expect 365–730 days from transplant to first harvest. Do not harvest in the first year. Leaves are toxic — eat stalks only. Thrives with cold winters.
