What shapes the seasons here

Frost is brief in Phoenix: the frosty spell typically runs only from about Jan 3 to Jan 5, and 1 year in 10 it stretches from Dec 18 to Jan 22. Tender crops can go in most of the year; summer heat, not frost, is the main limit.

Summer nights average 84°F in July. Above about 75°F, tomatoes and peppers stop setting fruit, so the best tomato planting here is Feb 10–24, Sep 18–26, timed so plants fruit before or after the hottest weeks.

Phoenix gets about 7 inches of rain a year, most of it in January, July and August. Plan on regular watering: most months get less than 1 inch.

161 of the 174 crops in the app grow here; 13 need a different climate (listed near the bottom).

Crops that struggle in Phoenix

These need a climate Phoenix doesn't have. Pots, shade cloth or a greenhouse can stretch the rules.

Banana: The frost-free season (about 363 days) is shorter than the 420 days it needs.
Blueberry: It needs acid soil, and dry-climate soil is usually alkaline. Grow it in a large pot of acid potting mix.
Ginger: The frost-free season (about 363 days) is shorter than the 270 days it needs.
Lemongrass: The frost-free season (about 363 days) is shorter than the 88 days it needs.
Muscadine grape: It needs acid soil, and dry-climate soil is usually alkaline. Grow it in a large pot of acid potting mix.
Papaya: Has to live outdoors through winter and needs nights no colder than about 48°F; the coldest month here averages 45°F.
Peanut: The frost-free season (about 363 days) is shorter than the 130 days it needs.
Pineapple: The frost-free season (about 363 days) is shorter than the 635 days it needs.

How these dates are worked out

Each crop has temperature limits and timing from university extension guides: how cold a night it can take, how much heat it can stand, how long it takes to mature, and how far before or after the last frost it goes in. Those are checked day by day against the Phoenix Sky Harbor Intl Airport station's NOAA 1991–2020 climate normals (average highs, lows, rain and frost dates). Dates are estimates for a typical year; a sheltered yard, a slope or a cold pocket can shift them by a week or two.
