Maryland’s Chesapeake Bay effect creates microclimates that shift chamomile planting times by several weeks across the state. Finding the best time to plant chamomile in Maryland depends on where you live and whether you start from seed or transplants.
Chamomile is a cool-season herb that thrives in Maryland’s spring and fall weather. Plant it too early and frost can kill seedlings. Plant it too late and summer heat will stunt growth.
This guide covers exact planting windows for every Maryland region, from the mountains to the coast. You’ll get step-by-step timing, soil prep tips, and common mistakes to avoid.
Best Time To Plant Chamomile In Maryland
The best time to plant chamomile in Maryland is early spring, about two weeks before the last expected frost date. For most of the state, that means mid-March to early April. Fall planting works well too, from late August to mid-September.
But these dates shift depending on your specific location. Let’s break it down by region.
Western Maryland Mountains
Western Maryland includes Garrett, Allegany, and Washington counties. These areas have colder winters and shorter growing seasons.
- Last frost date: Late April to early May
- Spring planting window: April 1 to April 20
- Fall planting window: August 15 to September 1
Start seeds indoors 4-6 weeks before your last frost date. For western Maryland, that means starting seeds in late February or early March.
Central Maryland
Central Maryland covers Baltimore, Howard, Montgomery, and Frederick counties. This region has moderate winters and reliable springs.
- Last frost date: Mid-April
- Spring planting window: March 20 to April 10
- Fall planting window: August 20 to September 10
Direct sowing works well here. Just wait until soil temperatures reach at least 60°F.
Eastern Shore And Southern Maryland
The Eastern Shore and southern Maryland have milder winters and earlier springs. The Chesapeake Bay moderates temperatures here.
- Last frost date: Late March to early April
- Spring planting window: March 10 to March 30
- Fall planting window: September 1 to September 20
These areas can sometimes plant chamomile as early as late February if the weather cooperates. Watch for late frosts though.
Why Timing Matters For Chamomile
Chamomile is sensitive to temperature. It germinates best when soil is between 60-70°F. Seedlings can handle light frost but not hard freezes.
Hot weather above 85°F causes chamomile to bolt and stop producing flowers. That’s why spring and fall planting work best in Maryland.
If you plant too late in spring, your chamomile might not flower before summer heat arrives. If you plant too early in fall, seedlings may not establish before winter.
Soil Temperature Check
Before planting, check your soil temperature. Use a simple soil thermometer inserted 2 inches deep.
- Wait for soil to reach 60°F consistently
- Check at the same time each morning
- Don’t plant if soil is below 50°F
- Ideal range is 60-70°F for germination
Maryland soil warms up faster in sandy loam than in clay. If you have heavy clay soil, wait an extra week after the recommended date.
How To Plant Chamomile In Maryland
Chamomile is easy to grow from seed. You have two options: direct sow or start indoors.
Direct Sowing Outdoors
Direct sowing is simplest. Follow these steps.
- Choose a sunny spot with well-draining soil
- Loosen soil to 6 inches deep
- Scatter seeds thinly on the surface
- Press seeds gently into soil – they need light to germinate
- Water gently with a fine spray
- Thin seedlings to 6-8 inches apart once they have 2 true leaves
Seeds germinate in 7-14 days. Keep soil moist but not waterlogged.
Starting Indoors
Starting indoors gives you a head start. This is useful for western Maryland where spring is short.
- Use seed starting mix in small pots
- Sow seeds on the surface, don’t cover them
- Mist with water and cover with plastic wrap
- Place in a warm spot (65-70°F)
- Remove plastic once seedlings appear
- Provide bright light, 14-16 hours daily
- Harden off for 7 days before transplanting
Transplant outdoors after the last frost date. Space plants 8-10 inches apart.
Fall Planting For Spring Blooms
Fall planting is less common but works well in Maryland. Chamomile planted in fall overwinters and blooms earlier the next spring.
For fall planting, sow seeds 6-8 weeks before the first expected frost. In Maryland, that’s typically:
- Western Maryland: August 15 to September 1
- Central Maryland: August 20 to September 10
- Eastern Shore: September 1 to September 20
Fall-planted chamomile needs mulch to protect roots over winter. Apply 2-3 inches of straw or shredded leaves after the ground freezes.
These plants will bloom in May, weeks before spring-planted chamomile. You’ll get a longer harvest period.
Maryland Microclimates And Adjustments
Maryland’s geography creates microclimates that shift planting times. Here are specific adjustments.
Urban Heat Islands
Baltimore and other cities are warmer than surrounding areas. Urban heat islands can shift planting dates by 1-2 weeks earlier in spring.
If you garden in Baltimore city, plant chamomile in early March instead of late March. Monitor soil temperature to be safe.
Bay Breezes
Properties near the Chesapeake Bay experience milder winters and cooler summers. The bay moderates temperature extremes.
Near the bay, spring planting can happen 1 week earlier than inland areas. Fall planting can extend 1-2 weeks later.
Elevation Changes
Higher elevations in western Maryland have shorter growing seasons. For every 1,000 feet of elevation, add 1 week to your planting delay.
Deep Creek Lake area (2,500 feet) should plant 2 weeks later than the rest of western Maryland.
Common Mistakes When Planting Chamomile
Avoid these errors to get the best results.
Planting Too Deep
Chamomile seeds need light to germinate. Never cover them with soil. Just press them gently into the surface.
If you bury seeds, they won’t sprout. This is the most common mistake new gardeners make.
Overwatering
Chamomile prefers consistent moisture but hates wet feet. Overwatering causes root rot and fungal diseases.
Water only when the top inch of soil feels dry. In Maryland’s humid summers, you may only need water every 2-3 days.
Planting In Shade
Chamomile needs full sun for best growth. Six to eight hours of direct sunlight is ideal.
In partial shade, plants get leggy and produce fewer flowers. Choose the sunniest spot in your garden.
Ignoring Soil Prep
Chamomile grows in poor soil but thrives in well-draining loam. Heavy clay soil needs amendment.
Mix in 2-3 inches of compost before planting. This improves drainage and adds nutrients.
Chamomile Varieties For Maryland
Two main types of chamomile grow well in Maryland. Choose based on your needs.
German Chamomile (Matricaria Recutita)
German chamomile is an annual. It grows quickly and produces lots of flowers. This is the best choice for tea and medicine.
- Grows 2-3 feet tall
- Blooms in 60-70 days from seed
- Self-seeds readily
- Best for spring planting
German chamomile is more tolerant of Maryland’s humidity than Roman chamomile.
Roman Chamomile (Chamaemelum Nobile)
Roman chamomile is a perennial. It forms a low-growing mat and works well as a ground cover.
- Grows 6-12 inches tall
- Blooms in 90-100 days from seed
- Hardy in zones 4-9
- Best for fall planting
Roman chamomile needs more winter protection in western Maryland. Mulch heavily after the first frost.
Harvesting Chamomile In Maryland
Harvest chamomile flowers when the petals start to curl back. This is when essential oils are most concentrated.
For spring-planted chamomile, harvest starts in June and continues through August. For fall-planted, harvest begins in May.
- Pick flowers in the morning after dew dries
- Pinch stems just below the flower head
- Harvest every 2-3 days for continuous blooms
- Dry flowers in a well-ventilated area out of direct sun
Store dried flowers in an airtight jar. They last up to one year.
Pests And Problems In Maryland
Chamomile is generally pest-resistant. But Maryland’s humid summers can cause issues.
Aphids
Aphids sometimes attack chamomile. Spray them off with a strong stream of water. Insecticidal soap works too.
Powdery Mildew
Powdery mildew appears in humid weather. Space plants for good air circulation. Water at the base, not on leaves.
Slugs And Snails
Slugs love moist chamomile beds. Use beer traps or diatomaceous earth. Remove mulch temporarily if slugs are bad.
Companion Planting With Chamomile
Chamomile benefits many garden plants. It attracts beneficial insects and improves flavor of nearby herbs.
- Plant near cabbage, onions, and cucumbers
- Avoid planting near mint or fennel
- Chamomile repels cabbage moths
- Attracts hoverflies and ladybugs
In Maryland gardens, chamomile works well as a border plant. It’s low-maintenance and adds delicate flowers.
Frequently Asked Questions
Can I plant chamomile in Maryland in summer?
Summer planting is risky in Maryland. Heat above 85°F stresses plants. If you must plant in summer, choose a spot with afternoon shade and water consistently.
How late can I plant chamomile in Maryland fall?
Plant at least 6 weeks before the first frost. For most of Maryland, that means no later than mid-September. In western Maryland, stop planting by September 1.
Does chamomile come back every year in Maryland?
German chamomile is annual and dies after one season. But it self-seeds freely, so new plants appear next year. Roman chamomile is perennial and returns for 3-4 years.
What’s the best soil pH for chamomile in Maryland?
Chamomile prefers slightly acidic soil with pH 5.6-7.5. Maryland soil is often acidic, so you may need lime. Test your soil before planting.
Can I grow chamomile in pots in Maryland?
Yes, chamomile grows well in containers. Use pots at least 8 inches deep. Move pots to a sheltered spot during heavy rain or frost.
Final Tips For Maryland Gardeners
Start small with chamomile. A 4×4 foot patch provides plenty of flowers for tea all summer. You can always expand next year.
Keep a garden journal. Note your planting dates and weather patterns. Over time, you’ll learn the perfect timing for your specific microclimate.
Join a local gardening group. Maryland has active Master Gardener programs in every county. They can give you hyperlocal advice.
Remember that chamomile is forgiving. Even if you miss the ideal window, you’ll likely get some flowers. Just adjust next season.
With the right timing and care, you’ll have chamomile blooming from late spring through early fall. Enjoy your tea garden.
