Best Time To Plant Chamomile In New Jersey

New Jersey’s coastal influence moderates temperatures, allowing chamomile to be planted slightly earlier than inland areas. Knowing the best time to plant chamomile in New Jersey is key to getting a healthy, fragrant harvest. This guide covers everything you need to know for successful planting in the Garden State.

Chamomile is a hardy, low-maintenance herb that thrives in New Jersey’s climate. Whether you choose German annual or Roman perennial chamomile, timing matters. Let’s break down the ideal planting windows for every region.

The absolute best time to plant chamomile in New Jersey is early spring, about two to four weeks before the last expected frost. For most of the state, this means mid-March to early April. In coastal areas like Atlantic City, you can start as early as late February.

Fall planting is also possible, but it requires more care. Aim for late August to mid-September, giving plants time to establish roots before winter. Spring planting is more reliable for beginners.

Understanding New Jersey’s Growing Zones

New Jersey spans USDA hardiness zones 6a to 7b. Northern counties like Sussex and Bergen are in zone 6a, with last frost dates around April 15–30. Southern counties like Cape May are in zone 7b, with last frosts as early as March 15–30.

Coastal areas benefit from the ocean’s warming effect, reducing frost risk. Inland areas, especially in the northwest, face colder snaps. Always check your local frost dates before planting.

Zone-Specific Planting Windows

Zone 6a (Northern NJ): Plant seeds indoors 6–8 weeks before last frost (late February). Transplant outdoors in early April.
Zone 6b (Central NJ): Direct sow seeds in mid-March to early April. Transplants can go out in late March.
Zone 7a (Southern NJ): Direct sow in early March. Transplants are safe by mid-March.
Zone 7b (Coastal): Start seeds indoors in January. Transplant outdoors in late February.

Spring Planting: The Preferred Method

Spring planting gives chamomile the longest growing season. For German chamomile, which flowers in 60–65 days, an early start means blooms by late May. Roman chamomile, a perennial, will spread and flower from June through September.

Start seeds indoors 6–8 weeks before your last frost date. Use seed-starting mix and keep soil moist. Chamomile seeds need light to germinate, so press them gently into the soil surface without covering.

Fill trays with moist seed-starting mix.
Sprinkle seeds thinly on top.
Mist with water to settle seeds.
Place under grow lights or in a sunny window.
Keep temperature around 65–70°F.
Seeds germinate in 7–14 days.
Harden off seedlings for a week before transplanting.

Direct Sowing in Spring

Direct sowing is simpler but riskier. Wait until soil temperature reaches at least 60°F. In most of New Jersey, this happens by mid-April. Scatter seeds on prepared soil and rake lightly to cover them with a thin layer of soil.

Water gently and keep soil moist until seedlings emerge. Thin plants to 6–8 inches apart once they have two true leaves. Chamomile self-sows readily, so you may get volunteers next year.

Fall Planting: For The Adventurous Gardener

Fall planting works best for Roman chamomile, which is perennial. Plant in late summer so roots establish before frost. In northern NJ, aim for late August. In southern NJ, early September is ideal.

German chamomile can be fall-planted, but it may not survive harsh winters. If you try, mulch heavily after the first frost. The plants will go dormant and regrow in spring.

Choose a site with well-draining soil.
Water deeply after planting.
Apply 2–3 inches of straw or leaf mulch.
Remove mulch in early spring.

Coastal Vs. Inland Planting Differences

New Jersey’s coastal influence is a game-changer. Along the shore, temperatures are milder in spring and fall. This allows for earlier spring planting and later fall planting. Inland areas, especially the Pine Barrens and northwest hills, have more extreme temperatures.

Coastal gardeners can plant chamomile seeds outdoors as early as late February. Inland gardeners should wait until mid-April. The difference is about 3–4 weeks.

Microclimates Matter

Your garden’s microclimate can shift planting times. A south-facing slope warms faster than a north-facing one. Urban areas like Newark and Jersey City are warmer than rural Sussex County. Observe your garden’s conditions and adjust accordingly.

If you live near the Delaware Bay, you get a similar moderating effect. The bay keeps temperatures stable, reducing frost risk. This allows for a longer growing season.

Soil Preparation For Chamomile

Chamomile prefers poor to average soil. Rich soil leads to leggy growth and fewer flowers. Test your soil pH; chamomile likes slightly acidic to neutral soil (pH 5.6–7.5).

Amend heavy clay soil with sand or compost to improve drainage. In sandy soil, add a little organic matter to retain moisture. Chamomile does not need fertilizer; too much nitrogen reduces essential oil content.

Remove weeds and rocks from the planting area.
Loosen soil to 6–8 inches deep.
Rake smooth before sowing seeds.
Water the soil before planting.

Watering And Care After Planting

Keep soil consistently moist until seeds germinate. Once seedlings are established, water deeply but infrequently. Chamomile is drought-tolerant once mature. Overwatering can cause root rot.

Water at the base of plants to avoid wetting leaves. Wet foliage encourages fungal diseases. In New Jersey’s humid summers, good air circulation is crucial.

Thinning and Spacing

Thin seedlings to 6–8 inches apart for German chamomile. Roman chamomile spreads via runners, so space plants 12 inches apart. Crowded plants are more prone to powdery mildew.

If you’re growing chamomile for tea, give plants extra space. More space means more air flow and healthier leaves. Harvest leaves and flowers regularly to encourage bushier growth.

Common Mistakes To Avoid

Planting too early is the biggest mistake. Chamomile seeds need warmth to germinate. Cold, wet soil causes rot. Wait until soil temperature is consistently above 60°F.

Another mistake is planting in rich soil. Chamomile thrives in lean conditions. Skip the compost and fertilizer. Over-fertilized plants produce lots of foliage but few flowers.

Don’t plant in heavy clay without amending.
Don’t let soil dry out during germination.
Don’t cover seeds with thick soil; they need light.
Don’t transplant without hardening off.

Harvesting Chamomile At The Right Time

Harvest flowers when petals start to curl back. This is when essential oils are highest. For German chamomile, this is about 60–65 days after planting. For Roman chamomile, flowers appear in late spring.

Harvest in the morning after dew dries. Pinch off flower heads with your fingers or use scissors. Dry them in a well-ventilated area out of direct sunlight. Store in an airtight container.

Check flowers daily once buds appear.
Pick flowers when petals are fully open but not drooping.
Spread flowers on a screen or paper towel.
Dry for 1–2 weeks until crisp.
Store in a dark, cool place.

Pests And Diseases In New Jersey

Chamomile is relatively pest-free. Aphids and spider mites can appear during dry spells. Spray them off with water or use insecticidal soap. Powdery mildew is common in humid weather; improve air circulation.

Slugs and snails may attack young seedlings. Use diatomaceous earth or beer traps. In wet springs, watch for damping-off disease. Avoid overwatering and use sterile potting mix for indoor starts.

Companion Planting with Chamomile

Chamomile is a great companion plant. It attracts beneficial insects like hoverflies and parasitic wasps. Plant it near cabbage, onions, and cucumbers. It also improves the flavor of herbs like basil and mint.

Avoid planting chamomile near potatoes or other nightshades. It can compete for nutrients. Chamomile’s shallow roots make it ideal for interplanting with deeper-rooted vegetables.

Year-Round Care Calendar For New Jersey

Here’s a month-by-month guide for chamomile care in New Jersey:

January–February: Start seeds indoors for spring planting.
March: Harden off seedlings; direct sow in coastal areas.
April: Transplant seedlings outdoors; direct sow inland.
May: Harvest first flowers; mulch around plants.
June–August: Regular harvesting; water during dry spells.
September: Plant Roman chamomile for fall; collect seeds.
October: Cut back dead foliage; apply winter mulch.
November–December: Protect plants with straw or leaves.

Choosing Between German And Roman Chamomile

German chamomile (Matricaria chamomilla) is an annual that grows 2 feet tall. It produces more flowers per plant and is best for tea. It self-sows readily, so you’ll get new plants each year.

Roman chamomile (Chamaemelum nobile) is a perennial ground cover. It grows 6–12 inches tall and has a creeping habit. It’s great for lawns or borders but produces fewer flowers. Both types can be planted in New Jersey.

German chamomile: Best for tea, annual, tall.
Roman chamomile: Best for ground cover, perennial, short.

Container Growing For Small Spaces

Chamomile grows well in containers. Use a pot at least 6 inches deep with drainage holes. Fill with well-draining potting mix. Place in full sun (6+ hours daily).

Water container plants more frequently than garden plants. Pots dry out faster. Fertilize lightly with a balanced liquid fertilizer once a month. German chamomile is especially suited for containers.

Overwintering Chamomile in New Jersey

Roman chamomile is hardy to zone 4, so it survives New Jersey winters easily. Cut back dead foliage in late fall and mulch with straw. In spring, remove mulch to allow new growth.

German chamomile dies after frost. Collect seeds in fall for next year’s planting. Let some flowers go to seed; they’ll self-sow in spring. You may get volunteer plants without any effort.

Frequently Asked Questions

Can I plant chamomile in July in New Jersey?
It’s not ideal. July is too hot and dry for successful germination. Wait until late August for fall planting, or start seeds indoors for next spring.

What is the best time to plant chamomile in New Jersey for fall harvest?
Plant in late August for a fall harvest. German chamomile will flower in 60 days, giving you blooms by late October. Roman chamomile will flower the following spring.

Does chamomile grow back every year in New Jersey?
Roman chamomile is perennial and returns each year. German chamomile is annual but self-sows, so it appears to come back. Both are reliable in New Jersey.

How late can I plant chamomile seeds in New Jersey?
You can direct sow seeds until mid-September in southern NJ, but early August is safer. Late planting may not give enough time for flowers before frost.

Should I soak chamomile seeds before planting?
No. Chamomile seeds are tiny and need light to germinate. Soaking can cause them to rot. Just press them into moist soil and keep them damp.

Final Tips For Success

Start small. Chamomile is forgiving, but beginners should plant a few seeds first. Once you see how easy it is, expand your patch. The scent alone is worth the effort.

Keep a gardening journal. Note your planting dates, frost dates, and harvest times. Over a few seasons, you’ll fine-tune the best time to plant chamomile in New Jersey for your specific location.

Share your harvest with neighbors. Chamomile tea is a wonderful gift. Dried flowers last for months. Enjoy the process and the peaceful ritual of tending these delicate plants.
