Chamomile, known for its calming properties and beautiful daisy-like flowers, is a beloved herb that thrives in various climates. In Oregon, with its diverse weather conditions and fertile soil, growing chamomile can be a rewarding endeavor. Whether you are a seasoned gardener or a beginner, this guide will provide you with all the information you need to successfully cultivate chamomile in Oregon.
There are two primary varieties of chamomile that you can grow: Roman chamomile (Chamaemelum nobile) and German chamomile (Matricaria chamomilla).
Roman Chamomile: This variety is a perennial herb, meaning it can return year after year. It typically grows to about 12 inches tall and has a more intense flavor.
German Chamomile: This variety is an annual plant that usually grows taller, reaching up to 24 inches. It has a sweeter fragrance and is commonly used for tea.
Both varieties can successfully grow in Oregon, but your choice may depend on whether you prefer a perennial or annual crop.
Oregon has a temperate climate that varies from coastal regions to more arid inland areas. Chamomile thrives best in full sun and well-drained soil.
Select a site that meets the above requirements:
Sun Exposure: A south-facing garden bed or area that receives ample sunlight throughout the day.
Air Circulation: Good air circulation helps prevent fungal diseases; avoid overcrowding plants.
Accessibility: Choose a location that is easy to access for maintenance, watering, and harvesting.
Before planting chamomile, prepare your soil to ensure optimal growth.
Conducting a soil test can provide valuable insights into nutrient levels and pH balance. Chamomile prefers slightly acidic to neutral soil (pH 6.0 to 7.0).
Based on your soil test results:
Organic Matter: Incorporate compost or well-rotted manure into the soil to enhance fertility and drainage.
pH Adjustment: If your soil is too acidic, consider adding lime; if too alkaline, sulfur can help lower pH levels.
Till the soil to a depth of at least 12 inches. This process improves aeration and allows roots to spread more easily.
You can opt to start your chamomile seeds indoors or directly sow them outdoors.
Timing: Start seeds indoors about 6 to 8 weeks before the last frost date in your area.
Containers: Use seedling trays or pots filled with seed-starting mix.
Sowing Depth: Scatter seeds on top of the soil and press them lightly—chamomile seeds require light for germination.
Conditions: Keep the soil moist but not soggy and maintain a temperature of around 70°F (21°C).
Timing: Wait until after the last frost date to sow seeds directly into outdoor beds (usually around mid-April in much of Oregon).
Spacing: Sow seeds about 12 inches apart, as chamomile will spread as they grow.
Watering: Gently water the area after sowing, ensuring not to wash away the seeds.
Chamomile seeds usually germinate within 7 to 14 days under ideal conditions. Once seedlings emerge, thin them out so that they have enough space to develop properly.
Chamomile prefers moderate watering—neither too dry nor overwatered is essential for healthy plants.
Water Frequency: Water once a week during dry spells, allowing the top inch of soil to dry out between waterings.
Technique: Focus on deep watering at the base of plants rather than overhead watering to prevent fungal issues.
Chamomile does not require heavy fertilization; too many nutrients can result in lush foliage at the expense of flower production.
Organic Fertilizers: Use organic options like fish emulsion or seaweed extract during early growth stages.
Application Rate: Follow package instructions for dilution rates, applying every four to six weeks throughout the growing season.
Regular maintenance helps support healthy growth and flowering throughout the season.
Removing spent blooms encourages further flowering:
Snip off flowers once they start wilting (ideally before they go to seed).
This practice promotes bushier growth and prolongs blooming time.
Regularly check for weeds competing with your chamomile plants for nutrients and water:
Chamomile generally attracts beneficial insects such as ladybugs, but it can occasionally be affected by pests like aphids or spider mites:
Knowing when and how to harvest chamomile ensures you get the most flavor and benefits from your plants.
The best time to harvest chamomile flowers is during late morning when the dew has dried but before noon:
Use scissors or garden shears to cut off flowers just above where they connect with stems.
Place harvested flowers in a basket or container while avoiding crushing them.
To enjoy your chamomile throughout the year:
Spread harvested flowers in a single layer on drying racks or paper towels in a well-ventilated area away from direct sunlight.
Allow them to dry completely (about one week) until brittle before storing in airtight containers away from light and moisture.
Growing chamomile in Oregon can be both productive and enjoyable with proper knowledge and care. By understanding the different species, preparing your garden site adequately, providing appropriate care through watering and fertilization, maintaining plant health through pruning and pest management, and harvesting correctly, you’ll be well on your way to enjoying your homegrown chamomile tea or using it in herbal remedies.
Whether you choose Roman or German chamomile, this delightful herb can enhance your garden’s beauty while providing natural wellness benefits—an excellent choice for any Oregon gardener!
