Growing Guide

When to Grow

Start thyme seeds indoors 8-10 weeks before the last frost, then transplant outdoors after the frost date. In USDA zones 5-9, this is usually between late March and May; check your local area’s frost dates for an accurate planting schedule. Alternatively, you can direct sow in the garden 2 weeks before the last frost. If you’re not sure how to find your area's first and last frost dates, consult our blog post 'Our Experts Answer Questions, Share Resources.'

How to Sow and Plant

Surface sow the seeds without covering them, as they need light to germinate. Keep soil moist and maintain a temperature of 60-75 F until seeds germinate. Space plants 6-9 inches apart and transplant to a full sun location once seedlings are sturdy.

How to Grow

Thyme loves heat and thrives in sunny, warm areas. If growing indoors, keep plants in a sunny window. Water thoroughly but sparingly, letting the soil dry between waterings. Use light mulch for moisture retention and weed control. Avoid over-fertilizing to preserve its pungent flavor. Thyme works well as a companion plant, attracting pollinators and deterring pests.

How to Save Seeds

  • Allow flowers to dry and turn brown.
  • Gently rub the browned flower stalks into a bag and winnow to separate.
  • Store in a cool, dark, dry place.
