Growing herbs in Zone 1
In Zone 1, the herb garden leans on annuals and the toughest perennials. Tender perennials like rosemary won't survive Zone 1 winters outdoors, so grow them in pots to bring inside; hardy thyme, chives, mint, and oregano return reliably. Annual basil, dill, and cilantro thrive once the soil warms after Late May – mid June.
The herbs below grow well in Zone 1. Use the zone's frost dates — last frost Late May – mid June, first frost Late July – mid August — to time sowing and transplanting right.
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 1
- 1
Don't over-fertilise herbs — rich soil reduces essential oil concentration and flavour.
- 2
Harvest regularly to prevent flowering (bolting), which turns leaves bitter.
- 3
Group drought-tolerant herbs (rosemary, thyme, sage) together and moisture-loving herbs (basil, mint, parsley) separately.
- 4
Mint spreads aggressively — always grow it in containers.
- 5
Use raised beds filled with imported soil mix to bypass permafrost
- 6
Start all vegetables indoors 6–8 weeks before last frost
