Growing vegetables in Zone 12
Zone 12's hot, nearly frost-free climate flips the vegetable calendar: fall, winter, and spring are the prime growing seasons, while brutal summer heat is the off-season for most crops. Focus on heat-tolerant varieties in summer and grow the widest range in the cooler months.
The vegetables below grow well in Zone 12. Use the zone's frost dates — last frost None, first frost None — to time sowing and transplanting right.
Vegetables are the backbone of most food gardens. Success comes down to matching crop requirements — days to maturity, heat or cold tolerance, spacing — to your zone's growing window. Short-season zones prioritise fast-maturing varieties; long-season zones can grow almost anything.
