Local data

Why this date changes by ZIP

Phoenix frost history and USDA zone 10a shift the safe planting window. GrowZone uses a local representative station instead of one national rule.

University of Arizona Extension is the kind of local source to verify against when a crop is expensive, weather is unusual, or your yard has a cold pocket.

Crop note

Cucumbers timing notes

Use a trellis if space is tight and keep soil evenly moist. Cucumbers prefers full sun, 12-18 in spacing, and soil near 65 F+.

For fall, count backward from Dec 15. A conservative last sowing target is around Oct 16.
