Growing Corn in Las Vegas

Las Vegas's Zone 9b Mojave Desert climate is defined by extreme summer heat — well above 110°F in July — and mild, pleasant winters. The gardening calendar runs opposite to most of the country: cool-season vegetables thrive October through March, and warm-season crops are best planted in spring (March–May) before the furnace of summer arrives. Drip irrigation and shade cloth are non-negotiable in Las Vegas gardens.

In Las Vegas (last frost around February 15), 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.
