Sunlight
How well it does at each level of direct sun per day.
Soil depth
Root room it needs — useful for sizing raised beds and containers.
Soil pH
The soil acidity it grows best in — most crops sit just below neutral, so this mostly matters for heavily amended or long-reused beds.
- Preferred range
- pH 4.0–8.0
Spacing
Room each plant needs — along the row and between rows — for sizing beds.
- In-row
- 12–24 in
- Between rows
- 12–24 in
Growth habit
The shape it makes in the bed and how tall it gets — what tells you whether to give it a trellis, a stake, or just room.
- Habit
- Low mound
- Mature height
- 6–12 in
Low and self-supporting — no staking needed.
Growing in containers
Whether it does well in a pot, planter, or window box — the SF balcony-and-deck question, weighing its footprint, form, and staying power, not just root depth.
Happy in a pot, planter, or window box — no garden bed required.
How to start it
Sow it where it grows, or raise it under cover and set it out — and how far ahead to start the seedlings if it's the latter.
- Usually
- Transplant
Goes in as a rooted start, cutting, or division rather than raised from seed.
Getting started
How it goes in the ground — how deep to sow or set it, and the soil temperature it needs to wake up. The cold-soil floor is the real limiter for direct-sowing in a foggy SF spring.
- Started from
- From seed
- Ideal soil temp
- 59–68°F
- Sow depth
- 0–0.125 in
- Time to emerge
- 7–14 days
Germinates between 59–68°F; happiest around 59–68°F.
Watering & feeding
How thirsty and how hungry it is — the water it wants and how much feeding the bed needs to keep it producing. In the fog belt even a thirsty crop drinks less than it would inland.
- Water need
- Low
- Feeding
- Light feeder
Gets by on less — water deeply, then let it dry out between; forgiving of a missed day.
Undemanding — good soil is plenty; a rich, fed bed does more harm than good.
A drought-tolerant Mediterranean herb — water sparingly, letting the soil dry between; it dislikes wet feet. Needs little to no feeding.
Pests & diseases
What tends to trouble this crop — what it is, what you'll see, and what to do about it, least-toxic first.
Our sources document no specific pests or diseases for this crop; it's generally grown without major pest trouble in home gardens.
Harvest & storage
How to tell it's ready to pick, and how to keep it once it's in.
- Keeps
- WeeksHolds a week or two in the fridge.
- Ready to harvest
- Snip fresh stems any time for cooking, best just before the blossoms open; leave the tough basal growth.
- Storing
- Fresh thyme keeps one to two weeks wrapped and refrigerated; it also dries and freezes very well.

Pollinators & wildlife
What this crop offers the garden's wildlife once it flowers — often the payoff for letting a bolting plant stand.
- Bees
- Honeybees and natives — bumble, mason, and sweat bees — working the flowers for pollen and nectar.
- Beneficial insects
- Hoverflies, lady beetles, and parasitoid wasps that keep aphids and caterpillars down.
A thyme allowed to bloom carpets itself in flowers so small and shallow that bees and hoverflies both feed easily; harvest sprigs all season and you never see it.
Companion planting
What grows well nearby, and what to keep apart.
No research-backed companion pairings for this crop — folk pairings without evidence are left out on purpose.
Earns its keep among brassicas — thyme helped reduce cabbage worms in broccoli, and with sage it knocked back diamondback moth on Brussels sprouts.
