In this comprehensive guide from Garden Aider, we will walk you through every step of cultivating healthy, vibrant chamomile. From choosing the best varieties to mastering watering techniques and troubleshooting common issues, you’ll gain the confidence to grow this beloved herb like a seasoned pro.
Understanding Chamomile: Varieties and Growth Habits
Before diving into the specifics of cultivation, it’s helpful to know a little about the two main types of chamomile you’ll typically encounter. Both offer similar benefits but have distinct growth patterns.
German Chamomile (Matricaria chamomilla or Matricaria recutita)
This is the most common type grown for tea and medicinal purposes. German chamomile is an annual, meaning it completes its life cycle in one growing season.
It grows upright, reaching 1-2 feet tall, producing numerous small, white flowers with yellow centers. It readily self-seeds, often returning year after year as if it were a perennial.
Roman Chamomile (Chamaemelum nobile)
Often called English chamomile, this variety is a true perennial. It forms a low-growing, mat-like groundcover, typically only 6-12 inches tall.
Roman chamomile flowers are slightly larger and less abundant than German chamomile, but its foliage is highly aromatic. It’s excellent for chamomile lawns or planting between stepping stones.
Choosing the Perfect Spot: Light, Soil, and Location
The foundation of healthy chamomile begins with selecting the ideal planting site. These plants are relatively unfussy but truly flourish when their basic needs are met.
Sunlight Requirements
Chamomile thrives in full sun exposure, meaning at least 6-8 hours of direct sunlight per day. While it can tolerate partial shade, too little sun will result in leggy growth and fewer flowers.
For optimal bloom production and plant vigor, choose the sunniest spot in your garden. This ensures robust growth and a strong aroma.
Soil Preferences
Chamomile prefers well-draining sandy loam. It does not like heavy, waterlogged soils, which can lead to root rot. If your soil is heavy clay, amend it with organic matter like compost or sand to improve drainage.
Aim for a slightly acidic to neutral soil pH, ideally between 6.0 and 7.5. A simple soil test kit can help you determine your soil’s pH and nutrient levels.
Ideal Garden Placement
Consider planting chamomile in herb gardens, cottage gardens, or as a fragrant border. Roman chamomile is perfect for pathways or areas where you want a scented groundcover.
German chamomile works well in raised beds or containers, especially if you plan to harvest frequently. Ensure good air circulation around the plants to prevent fungal issues.
Planting Your Chamomile for Success
Once you’ve chosen your site, it’s time to get your chamomile plants into the ground. Both varieties are typically grown from seed.
Starting From Seed
Chamomile seeds are tiny and require light to germinate. For German chamomile, direct sowing outdoors after the last frost is often the easiest method.
- Prepare a finely tilled seedbed.
- Scatter seeds lightly over the soil surface.
- Gently press them in, but do not cover them with soil.
- Keep the area consistently moist until germination, which usually occurs within 7-14 days.
For an earlier start, particularly with Roman chamomile or in cooler climates, you can start seeds indoors 4-6 weeks before the last frost. Place them on top of seed-starting mix and keep them in a bright location. Cultivating thriving greenery indoors for seed starting can give your plants a head start.
Transplanting Seedlings
If you started seeds indoors or purchased young plants, transplant them carefully. Dig a hole as deep as the root ball and twice as wide.
Space German chamomile plants about 6-12 inches apart, as they will grow into fuller bushes. Roman chamomile can be spaced 6-8 inches apart to encourage a dense mat.
Essential Watering Techniques for Chamomile
Proper watering is crucial for healthy chamomile, especially during establishment and dry periods. While chamomile is somewhat drought-tolerant once mature, consistent moisture promotes better flowering.
Initial Watering
After planting seeds or transplanting seedlings, water thoroughly to settle the soil around the roots. Ensure the soil remains consistently moist, but not waterlogged, for the first few weeks.
Established Plants
Once established, chamomile plants prefer the soil to dry out slightly between waterings. Check the soil moisture by sticking your finger about an inch deep into the soil.
If it feels dry, it’s time to water. Deep watering is better than frequent shallow watering, as it encourages stronger root development.
Monitoring for Drought Tolerance
Mature chamomile exhibits good drought tolerance. However, prolonged dry spells, especially during flowering, can reduce bloom production and plant vigor.
During hot, dry weather, you may need to water more frequently, perhaps every few days. Observe your plants for wilting leaves, which indicate a need for water.
Nourishing Your Plants: Fertilization and Soil Health
Chamomile is not a heavy feeder and generally thrives in average garden soil without excessive fertilization. Too much fertilizer can encourage leafy growth at the expense of flowers.
Minimal Fertilization
If your soil is reasonably fertile and amended with compost at planting, additional fertilizer may not be necessary. Chamomile prefers nutrient-poor to moderately fertile soil.
If your soil is very poor or you notice stunted growth, a balanced, all-purpose liquid fertilizer (e.g., 5-10-5 or 10-10-10 NPK ratios) can be applied once or twice during the growing season at half strength. Apply it during active growth, not when the plant is just establishing or nearing the end of its cycle.
Mulching for Soil Health
Applying a thin layer of organic mulch, such as straw or shredded leaves, around your chamomile plants can be beneficial. Mulch helps to:
- Retain soil moisture.
- Suppress weeds.
- Regulate soil temperature.
- Slowly add organic matter to the soil as it decomposes.
Keep mulch a few inches away from the plant stems to prevent moisture buildup and potential stem rot.
Pruning and Deadheading for Continuous Blooms
Regular maintenance, particularly pruning and deadheading, will keep your chamomile looking tidy and producing an abundance of flowers.
The Art of Deadheading
Deadheading is the practice of removing spent or faded flowers. For chamomile, this is highly recommended for German varieties.
- Pinch or snip off the faded flowers just above a leaf node or new bud.
- This prevents the plant from expending energy on seed production.
- Instead, it channels that energy into producing more flowers.
Deadhead regularly, ideally every few days, during the peak blooming season for a continuous supply of fresh flowers.
Light Pruning
For German chamomile, light pruning throughout the season can encourage bushier growth. If plants become leggy, you can trim them back by about one-third.
Roman chamomile, used as a groundcover, benefits from occasional mowing or shearing to keep it tidy and encourage denser growth. Do this after the main flush of flowering.
Protecting Your Chamomile: Common Pests and Diseases
Chamomile is generally quite resilient, but like all plants, it can occasionally encounter pests or diseases. Vigilance is your best defense.
Common Pests
- Aphids: These small, soft-bodied insects cluster on new growth and the undersides of leaves, sucking plant sap.
- Spray affected plants with a strong stream of water to dislodge them.
- For heavier infestations, use insecticidal soap, ensuring good coverage.
- Thrips: Tiny, slender insects that feed on flower petals and leaves, causing silvery streaks and distortion.
- Introduce beneficial insects like ladybugs or lacewings.
- Use sticky traps to monitor and reduce populations.
Fungal Diseases
- Powdery Mildew: Appears as white, powdery patches on leaves and stems, especially in humid conditions with poor air circulation.
- Ensure good air circulation by proper spacing.
- Remove affected leaves.
- Spray with a fungicide approved for organic gardening, like neem oil or a baking soda solution.
- Root Rot: Caused by overly wet soil. Symptoms include wilting, yellowing leaves, and stunted growth.
- Prevent by planting in well-draining soil.
- Avoid overwatering. Once root rot sets in, it’s often difficult to save the plant.
How to Care for Chamomile Plants Through the Seasons
Understanding the seasonal needs of chamomile helps ensure its vitality year-round, even if German chamomile is an annual.
Spring: Awakening and Planting
Spring is the time for starting new German chamomile plants from seed. As temperatures rise, prepare your garden beds with rich compost.
For Roman chamomile, spring is when it emerges from dormancy. Provide it with a light feeding of compost if needed.
Summer: Peak Growth and Harvest
This is the main growing and flowering season. Ensure consistent watering, especially during dry spells.
Regular deadheading is crucial for continuous blooms. Monitor closely for pests and diseases, addressing any issues promptly. This is when you’ll truly see how to care for chamomile plants pays off with abundant flowers.
Fall: Winding Down
For German chamomile, flowering will slow, and plants will begin to die back after setting seed. You can collect seeds for next year’s planting.
Roman chamomile will continue to provide groundcover until the first hard frost. Cut back any leggy growth to maintain its shape.
Winter: Dormancy or End of Life Cycle
German chamomile will die completely with the first hard frost. Its seeds will remain in the soil, ready to germinate next spring.
Roman chamomile is cold hardy in many zones. It will go dormant, losing some foliage but returning in spring. In very cold climates, a layer of mulch can provide extra winter protection.
Harvesting and Enjoying Your Chamomile
The best part of growing chamomile is undoubtedly the harvest! Knowing when and how to pick the flowers ensures you get the most potent and fragrant yield.
When to Harvest
Harvest chamomile flowers when they are fully open but before they start to wilt or turn brown. This is typically when the petals are flat or slightly reflexed.
The ideal time of day is usually in the morning after the dew has dried but before the midday sun becomes too intense.
How to Harvest
Gently pinch or snip off the flower heads, leaving a small portion of the stem attached. Avoid pulling, which can damage the plant.
Harvest regularly, every few days, to encourage more blooms.
Drying and Storage
To dry chamomile, spread the fresh flowers in a single layer on a clean screen, mesh tray, or paper towel in a warm, dry, well-ventilated area out of direct sunlight.
They are fully dry when the petals and centers feel crisp. Store dried flowers in an airtight container in a cool, dark place. They will retain their potency for about a year.
Troubleshooting Chamomile Plant Problems
Even with the best care, sometimes your chamomile might throw you a curveball. Here’s a quick guide to common issues and their solutions.
Chamomile Troubleshooting Checklist
| Symptom | Possible Cause | Solution |
|---|---|---|
| Leggy, sparse growth; few flowers | Insufficient sunlight | Move to a location with full sun (6-8+ hours). |
| Yellowing leaves, wilting despite watering | Overwatering / Poor drainage (Root Rot) | Ensure well-draining soil. Reduce watering frequency; allow soil to dry between waterings. |
| Flowers turning brown quickly, plant looks stressed | Underwatering / Drought stress | Increase watering frequency, especially during hot, dry periods. Mulch to retain moisture. |
| White, powdery patches on leaves | Powdery Mildew | Improve air circulation. Remove infected leaves. Apply neem oil or fungicidal spray. |
| Small green insects on new growth; sticky residue | Aphids | Blast with water. Apply insecticidal soap. Encourage beneficial insects. |
| Stunted growth, leaves curling or distorted | Nutrient deficiency (rare) or Pest infestation | Perform a soil test. Apply a balanced liquid fertilizer at half strength. Check for pests like aphids or thrips. |
| Plant dies back completely in fall | Normal for German Chamomile (annual) | This is expected. Collect seeds for next year or allow to self-seed. Roman chamomile is perennial. |
FAQs About Chamomile Plant Care
Can I Grow Chamomile in Pots or Containers?
Yes, both German and Roman chamomile grow well in containers. Choose pots with good drainage holes and use a quality potting mix. Ensure they receive ample sunlight and water more frequently than ground-planted chamomile, as containers dry out faster.
Is Chamomile Safe for Pets?
German chamomile (Matricaria chamomilla) is generally considered non-toxic to cats and dogs, and is even used in some herbal remedies for pets. However, Roman chamomile (Chamaemelum nobile) can be mildly toxic if ingested in large quantities. Always exercise caution and consult a vet if you have concerns.
Why Are My Chamomile Flowers Not Fragrant?
Lack of fragrance can be due to several factors: insufficient sunlight, poor soil, or harvesting at the wrong time. Ensure your plants receive full sun and are growing in well-draining soil. Harvest flowers when they are fully open for the best aroma.
Do I Need to Fertilize My Chamomile Plants?
Chamomile is not a heavy feeder. In most cases, if your soil is reasonably healthy and amended with compost, additional fertilization is unnecessary.
