This guide answers when to plant chamomile zone 7 with timing worked out from USDA Zone 7 frost-date averages, not guesswork. Chamomile is the small, daisy-like herb of calming teas and cottage gardens, and in Zone 7 it is an easy, hardy annual that self-sows freely once you have grown it once. It needs little: sun, ordinary soil and a light hand. Sow it in spring, let it flower through summer, and pick the little white-and-yellow flowers for tea as they open.
Zone 7 at a glance
Zone 7 covers areas where average annual minimum temperatures run 0 to 10°F. The average last spring frost falls in the Mar 15–Apr 1 range and the average first autumn frost in the Nov 1–15 range — these are USDA zone averages from USDA and NOAA frost records, not exact dates for any one garden, so check your local extension service before planting tender crops outside. Use the frost date calculator to work out dates for your own garden, and browse the planting calendar hub for the full Zone 7 year.
When to plant chamomile in Zone 7
| Step | Timing in Zone 7 |
|---|---|
| Start indoors | February to March indoors, or direct sow |
| Direct sow outdoors | March to April, about 2 to 4 weeks before the last frost — sow on the surface |
| Transplant outdoors | April, once seedlings are sturdy |
| Autumn / second sowing | August for a late crop |
| Harvest | June to August, picking flowers as they open |
The table above is the short answer. The detail matters because chamomile is hardy — a hardy crop that tolerates light frost, so it can go out weeks before the last frost. Start indoors when the table says so, using the seed-starting calculator to count back from your last frost, and harden seedlings off for a week before they go outside. The Zone 7 April guide shows what else is happening in the garden in that month.
How to plant chamomile
Sow indoors in February to March, or direct sow in March to April, about 2 to 4 weeks before the last frost. Seed needs light to germinate, so sow on the surface and press it gently into the soil without covering it; germination takes 7 to 14 days. Space plants 6 to 12 inches apart in well-drained soil with a pH of 5.5 to 7.0, in full sun. Chamomile self-sows, so let a few plants set seed for next year.
Give chamomile full sun — at least six hours of direct sun a day for full-sun crops, or morning sun with afternoon shade where part shade is listed. Prepare the bed by forking in compost and removing stones and weeds, and check the soil pH: chamomile prefers 5.5–7.0. Space plants 6–12 inches apart — the spacing in the table below — and sow seed at the depth on the packet, keeping the seedbed moist until germination, which takes 7–14 days.
| Fact | Range |
|---|---|
| Sun | full sun |
| Days to germination | 7–14 |
| Days to maturity | 60–90 |
| Spacing | 6–12 inches |
| Soil pH | 5.5–7.0 |
| Sowing method | both |
| Cold tolerance | hardy |
| Water needs | moderate |
Watering and feeding
Chamomile has moderate water needs: keep the soil moist until plants are established, then water only in dry spells. It needs little feeding — compost at planting is enough — and too much nitrogen makes leafy plants with few flowers. It grows well in poor soil, which is part of its charm as a cottage-garden plant.
A layer of mulch — straw, shredded leaves or compost — helps on both fronts: it holds moisture in the soil, keeps roots cool, and stops soil splashing onto leaves and fruit. Keep mulch a few inches away from stems so it does not trap damp against them.
Companion plants and rotation
Good companions for chamomile include tomatoes, peppers, marigolds, cabbage. Use the companion planting finder to plan combinations for your whole bed. Rotate crops each year: do not plant chamomile where the same family grew last year, and keep a simple note of what grew where so you can rotate properly next season. Also see our guide to when to plant lavender in Zone 7, which pairs well with chamomile in a Zone 7 bed.
Pests and problems
The common pests for chamomile are aphids, slugs, thrips. Chamomile has few pests; slugs may nibble young seedlings, so protect them until established. Check plants weekly, looking under leaves as well as on top — most problems are easy to deal with if caught early. Good air flow helps: do not crowd plants, water at the base rather than over the leaves, and clear away dead leaves and debris where pests hide.
Harvesting and storing
Pick flowers as they open, usually 60 to 90 days after sowing, pinching the flower heads off in the morning when they are dry. Pick often — regular picking encourages more flowers. Dry the heads in a single layer in a shady, airy place, then store in a sealed jar away from light; dried chamomile keeps for months and makes a gentle tea.
For the best flavour, harvest in the morning, when plants are cool and their moisture and oils are at their best, and use a sharp knife or scissors for a clean cut that heals quickly.
Frequently asked questions
When should I plant chamomile in Zone 7?
March to April, about 2 to 4 weeks before the last frost — sow on the surface. As a rule, work back from the average last frost range of Mar 15–Apr 1 for spring planting, and back from the average first frost range of Nov 1–15 for autumn planting. These are zone averages, so check your local extension service for your area.
Can I grow chamomile in containers?
Yes, in most cases — choose a pot at least 12 inches deep with drainage holes, fill it with good potting mix, and water more often than beds, since pots dry out faster. Container growing suits chamomile well, especially where garden soil is heavy or space is limited.
How long does chamomile take to grow?
About 60–90 days to maturity from sowing or transplanting, depending on variety and weather. Germination takes 7–14 days. Warm, sunny weather speeds growth; cold or cloudy weather slows it, so treat these as ranges, not exact dates.
What soil pH does chamomile need?
A pH of 5.5–7.0 is ideal. Test your soil before planting and amend it if needed — your local extension service can test a sample and advise on what to add.
What grows well with chamomile?
Good companions include tomatoes, peppers, marigolds, cabbage. Avoid planting it where the same family grew last year, and give it the spacing and sun listed in the table above so companions do not crowd it out.
