Growing Rhubarb in Scottsdale

Scottsdale's Zone 10a desert climate at the edge of the McDowell Mountains combines Phoenix-area heat with slightly more varied terrain. The gardening approach is the same as across the greater Phoenix metro: maximize the cool winter-spring window and plan carefully around the brutal summer. Raised beds, quality soil, and drip irrigation allow Scottsdale gardeners to produce impressive yields of vegetables, herbs, and even some subtropical fruit.

In Scottsdale (last frost around January 28), rhubarb can go out around January — 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.
