Growing vegetables in Zone 9
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.
