Growing Notes

  • Rosemary seeds can be difficult to germinate, and should started and overwintered in USDA hardiness zones 7 and lower. Starting your seeds indoors, or on a heat mat, will also result in higher germination rates and better overall results.
  • It is recommended to soak the seeds for 4-6 hours before sowing to soften the seed coat and prime the seeds to germinate.
  • Rosemary is tolerant of a relatively wide range of soil conditions, and as an evergreen is somewhat drought tolerant. Wilting, sagging branches are a sign that the bush is stressed and requires water.

Once established, Rosemary is a hardy evergreen that is somewhat tolerant to mild frost. The recommended hardiness USDA zones are 8-10, but rosemary can be grown in a sun room or greenhouse. If growing in a climate below zone 8, the plants should be kept indoors until the night temperatures exceed at least 55 degrees Fahrenheit. Overwinter in a south or south-eastward facing window.

If growing in co, you will need to transplant to larger containers. A full grown rosemary bush may need a 10 gallon pot or larger at maturity.

Rosemary can be shaped and manicured to promote a more attractive, compact addition to your herb garden.


Leaves and stems can be harvested anytime approximately 85 days after germination. For smaller quantities, the tip of the branch can be cut with a snip. Larger amounts can be collected by cutting stem to within 2-3 nodes of the main woody base.
