Known for its soothing and healing properties, calendula is often used in teas, salves, tinctures, and skin-care remedies. Harvesting calendula correctly ensures that the flowers retain their therapeutic qualities, vibrant color, and aroma, providing maximum benefits for both culinary and medicinal uses. This article provides a comprehensive guide on harvesting calendula for teas and salves, including selection, timing, harvesting techniques, drying, storage, and preparation methods.
Why Harvest Calendula?
Calendula is a versatile herb with numerous benefits:
- Medicinal Uses: Calendula flowers contain anti-inflammatory, antifungal, and antibacterial compounds, making them ideal for skin salves and soothing teas.
- Culinary Uses: Adds color, mild flavor, and nutrition to salads, soups, and herbal teas.
- Home Remedies: Calendula is often used in balms, salves, and infused oils to treat minor cuts, burns, and skin irritations.
- Sustainability: Home harvesting reduces dependence on store-bought dried flowers and ensures freshness and purity.
- Economic and Educational Value: Growing and harvesting calendula can be a cost-effective way to produce herbal remedies while learning about plant life cycles.
Step 1: Selecting the Right Calendula Plants
The quality of harvested flowers starts with selecting healthy plants:
Traits to Consider:
- Healthy Growth: Choose plants free from pests, diseases, and discoloration.
- Vibrant Blooms: Look for large, brightly colored yellow, gold, or orange flowers.
- Continuous Flowering: Select plants that produce multiple blooms for an extended harvest season.
- Open-Pollinated Varieties: Ideal for seed saving if you wish to continue growing calendula in subsequent years.
Tip: Ensure your calendula garden is in full sun with well-draining soil to maximize flower production.
Step 2: Understanding Calendula Flower Development
Knowing the right stage to harvest ensures maximum potency and color retention:
Flower Maturity:
- Calendula flowers are at peak potency when fully open but not over-mature.
- Petals should be vibrant, firm, and free from wilting.
- Avoid harvesting flowers with signs of damage, disease, or browning petals.
Timing:
- Harvesting is best done in the morning after the dew has evaporated, when essential oils and active compounds are most concentrated.
- Regular harvesting encourages further blooming throughout the season.
Step 3: Tools and Preparation for Harvest
Gather the necessary tools and materials for a smooth harvesting process:
- Sharp scissors or garden shears: For cleanly cutting flower heads without damaging the plant.
- Baskets or paper bags: To collect flowers gently without crushing petals.
- Gloves (optional): Protect hands from rough stems or sap.
- Drying racks or trays: Prepare a ventilated area for air drying.
Tip: Avoid plastic bags for collection, as they can trap moisture and cause flowers to mold.
Step 4: Harvesting Calendula Flowers
Proper technique ensures flowers retain their color, aroma, and medicinal properties:
Step 1: Cutting the Flowers
- Cut the flower head with 1–2 inches of stem attached.
- Handle flowers gently to avoid bruising or tearing petals.
Step 2: Sorting and Quality Control
- Remove damaged, wilted, or insect-affected blooms.
- Use only firm, vibrant flowers for teas and salves to maximize potency and visual appeal.
Step 5: Drying Calendula Flowers
Drying is crucial to preserve calendula’s color, flavor, and medicinal properties:
Air Drying:
- Spread flowers in a single layer on a drying rack, tray, or screen.
- Keep in a cool, dark, well-ventilated area away from direct sunlight.
- Drying usually takes 1–2 weeks, depending on humidity.
- Turn flowers occasionally for even drying.
Alternative Drying:
- Hang small bundles upside down in a dark, ventilated area.
- Ensure good airflow to prevent mold and discoloration.
Tip: Flowers are ready for storage when petals are crisp, dry to the touch, and stems snap easily.
Step 6: Storing Dried Calendula Flowers
Proper storage maintains freshness and medicinal properties:
Storage Containers:
- Glass jars with airtight lids
- Paper envelopes or cloth bags for short-term storage
- Avoid plastic containers unless airtight and moisture-free
Storage Conditions:
- Cool, dark, and dry location
- Avoid humidity and temperature fluctuations
- Label containers with harvest date and variety for easy tracking
Tip: Dried calendula flowers can retain their potency for up to one year when stored correctly.
Step 7: Using Calendula Flowers in Teas
Calendula teas are soothing, anti-inflammatory, and aromatic:
Step 1: Preparation
- Use 1–2 teaspoons of dried petals per cup of hot water.
- Steep for 5–10 minutes, depending on desired strength.
- Strain flowers before drinking.
Health Benefits:
- Calendula tea may aid digestion, soothe sore throats, and provide mild anti-inflammatory effects.
- Combining with herbs like chamomile, mint, or lemon balm can enhance flavor and medicinal properties.
Step 8: Using Calendula Flowers in Salves
Calendula-infused oils are the base for medicinal salves:
Step 1: Making Calendula Oil
- Place dried or fresh petals in a jar with a carrier oil such as olive or almond oil.
- Infuse using a slow heat method (double boiler or sun-infused) for 2–6 weeks.
- Strain petals to obtain a golden, aromatic calendula oil.
Step 2: Making Salve
- Combine infused oil with beeswax in a 4:1 ratio (oil:beeswax).
- Melt gently, stir, and pour into containers.
- Let solidify to create a healing salve for cuts, burns, and dry skin.
Tip: Store salves in cool, dark places to maintain effectiveness.
Step 9: Tips for Continuous Calendula Harvest
- Succession Planting: Sow seeds every 2–3 weeks to ensure a continuous bloom and harvest.
- Deadhead Regularly: Encourage more flowers and prolonged harvesting season.
- Avoid Chemical Sprays: Ensure flowers are pesticide-free if used for teas or salves.
- Record Keeping: Track bloom times, flower size, and oil/salve yields for future planning.
- Companion Planting: Plant near vegetables or herbs to attract pollinators and support garden health.
