Growing herbs in Zone 10
Herbs are among the highest-value crops by square foot and among the easiest to grow. Most culinary herbs prefer well-drained soil and at least partial sun. Annual herbs like basil are direct-sown each season; perennial herbs like rosemary and thyme return year after year in mild zones.

Tips for growing herbs in Zone 10

Don't over-fertilise herbs — rich soil reduces essential oil concentration and flavour.
- 2
Harvest regularly to prevent flowering (bolting), which turns leaves bitter.

Mint spreads aggressively — always grow it in containers.

Plant cool-season vegetables (tomatoes, peppers) in October–February to avoid peak heat

Grow tropical vegetables year-round: calabaza, bitter melon, cassava
