Growing essentials

What rosemary need to thrive.

Use the practical details below with your Zone 6 timeline. Current weather and the variety you choose can shift timing.

LightFull sun
SoilVery well-drained soil or a coarse container mix
Planting depthPlant at the same depth as its nursery pot.
Spacing24–36 inches apart; larger varieties need more space
WaterLet the upper soil dry between deep waterings; never leave the pot standing in water.
Best conditionsMatch planting to local frost dates; mature hardiness and summer heat tolerance vary.

How to plant

Plant it well.

Start with a nursery plant or rooted cutting. Plant after frost in sharply drained soil or a container with drainage holes.

Indoors or containers

Overwinter in the brightest cool window or under lights; indoor light and overwatering are common challenges.

Keep it growing

Care through the season.

  • Clip soft green tips lightly to maintain a bushy shape; leave some stems to flower.
What to avoid

Keeping roots constantly wet or cutting back into bare old wood.

Ready to harvest

Know the cue, not just the date.

  • Snip short leafy tips as needed after new growth appears; avoid taking more than about one-third at a time.
