How to Start It
Take a softwood cutting from an existing plant — fast and reliable.
Seed is slow and unreliable; cuttings root in a few weeks. Below zone 7, grow it in a pot and overwinter it indoors.
When To Start
First Chance to Plant
After last frost — rosemary is frost tender
Last Chance to Plant

Planting & Sprouting
Growing Tips
- 1Rosemary is slow and unreliable from seed — start it from a cutting instead.
- 2Give it gritty, sharply-drained soil and let it dry between waterings; soggy roots are what kills it.
- 3In zones below 7, grow it in a pot and bring it to a bright, cool spot indoors over winter.

Harvesting
When to Pick
Snip sprigs anytime once established; flavour is strongest just before flowering
How to Harvest
- 1Once a plant is established, cut 8–10 cm sprigs from the soft new growth as needed, never taking more than a third of the plant at once.
- 2Cutting often keeps it bushy.
- 3Strip the needles from woody stems for cooking.
