Growing Corn in Glendale

Glendale's Zone 10a climate northwest of Phoenix follows the same desert gardening calendar as the rest of the greater Phoenix area. Winter and spring are the prime growing seasons for most vegetables, with cool-season crops thriving from October through April and warm-season crops fitting into the February–May window before summer heat intensifies. Efficient irrigation is the cornerstone of any successful Glendale garden.

In Glendale (last frost around January 28), aim to direct sow or transplant corn outside around February — approximately 2 weeks after your last expected frost.

Corn thrives between 65°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 60–100 days from transplant to first harvest. Needs warm soil. Plant in blocks.
