Growing Rhubarb in Toledo

Toledo's Zone 6a location at the western end of Lake Erie gives gardeners about 179 frost-free days. The lake effect can bring cloudy conditions but also moderates the worst temperature extremes. Warm-season crops like tomatoes and peppers need an indoor start in late March. The region's flat terrain and historically rich agricultural soils — part of the old Lake Erie lakebed — are naturally excellent for vegetables.

In Toledo (last frost around April 22), 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.
