Growing Sweet Potato 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), aim to direct sow or transplant sweet potato outside around February — approximately 2 weeks after your last expected frost. Starting seeds indoors 6 weeks before the last frost date gives you a significant head start.

Sweet Potato thrives between 70°F and 95°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 90–120 days from transplant to first harvest. Needs very warm, long season.
