Introduction
Calendula, commonly known as pot marigold, is a delightful addition to any garden. With its bright yellow and orange blossoms, calendula not only brings vibrant color to your outdoor space but also offers numerous health benefits. Known for its healing properties, calendula is often used in herbal remedies, natural skincare products, and teas. Moreover, it attracts pollinators, making it a great companion plant in your vegetable or flower garden.
Growing calendula from seed is an easy and rewarding process, even for beginner gardeners. This resilient and low-maintenance plant thrives in various conditions, and with the right steps, you can enjoy its beauty and benefits throughout the growing season. In this article, we’ll walk you through how to grow calendula from seed, ensuring a successful and bountiful bloom.
Why Grow Calendula?
Before diving into the process, let’s explore why calendula is such a beloved plant among gardeners:
- Medicinal Uses: Calendula has been used for centuries for its medicinal properties, particularly in healing wounds, reducing inflammation, and soothing skin irritations. Calendula-infused oils and salves are popular in natural skincare.
- Pollinator-Friendly: Calendula attracts beneficial insects such as bees and butterflies, which help pollinate your garden. It’s a great plant to grow alongside vegetables to encourage a healthy ecosystem.
- Easy to Grow: Calendula is a hardy plant that grows well in various conditions, making it ideal for beginner gardeners. It can tolerate cool weather, poor soil, and even light frost.
- Self-Seeding: Once calendula is established, it will often self-seed, meaning it will continue to come back year after year with minimal effort.
How to Grow Calendula from Seed: A Step-by-Step Guide
Growing calendula from seed is a straightforward process that doesn’t require any special equipment or expertise. Here’s how to get started:
Step 1: Choose the Right Location
Calendula thrives in areas with full sunlight, but it can tolerate partial shade, especially in warmer climates. To ensure the healthiest growth and most abundant blooms, choose a spot in your garden that receives at least 6-8 hours of direct sunlight per day.
Calendula is relatively forgiving when it comes to soil, but it performs best in well-draining, moderately fertile soil. If your garden soil is heavy or clay-like, consider adding some compost or organic matter to improve its structure and drainage.
Tip: If you’re short on space, calendula also grows well in containers. Just be sure to select a pot with good drainage and place it in a sunny location.
Step 2: Prepare the Soil
To give your calendula seeds the best start, you’ll want to prepare the soil before sowing. Here’s how:
- Loosen the soil: Use a garden fork or tiller to loosen the soil to a depth of about 12 inches. This helps create a welcoming environment for the roots to grow.
- Add organic matter: If your soil is lacking in nutrients, mix in compost or well-rotted manure. This will enrich the soil and provide the young calendula plants with the nutrients they need to thrive.
- Ensure good drainage: Calendula doesn’t like soggy soil. If your garden tends to retain water, you may need to add some sand or grit to improve drainage.
Tip: Calendula can tolerate poor soil conditions, so if you’re planting in less-than-ideal soil, don’t worry too much. The plant’s resilience will help it adapt to a variety of conditions.
Step 3: Sow the Seeds
Calendula seeds can be sown directly into the garden bed or started indoors if you prefer to get a head start on the growing season. Here’s a breakdown of both methods:
Direct Sowing Outdoors:
- When to sow: Calendula seeds can be sown outdoors in early spring as soon as the soil is workable. It tolerates cooler temperatures and light frost, making it one of the first flowers you can plant in the growing season.
- How to sow: Scatter the seeds over the prepared soil and lightly press them into the surface. Cover the seeds with a thin layer of soil (about 1/4 inch) and water gently to keep the soil moist during germination.
- Spacing: For a full, bushy plant, space the seeds about 6-12 inches apart. This will give each plant enough room to grow and spread out.
Starting Indoors:
- When to start: If you want to get a head start on the growing season, you can start calendula seeds indoors 6-8 weeks before the last expected frost date.
- How to start: Plant the seeds in seed trays or small pots filled with seed-starting mix. Lightly cover the seeds with soil and keep them moist until they germinate. Once the seedlings are about 3 inches tall, they can be transplanted into the garden after the danger of frost has passed.
Step 4: Watering and Maintenance
Calendula is relatively low-maintenance, but it does require consistent moisture to thrive. Here’s how to care for your calendula plants:
- Watering: Keep the soil evenly moist during the germination period and throughout the growing season. Water the plants deeply but avoid overwatering, as calendula doesn’t like soggy conditions. Once established, calendula is somewhat drought-tolerant but still benefits from regular watering.
- Mulching: Apply a layer of organic mulch around the base of the plants to help retain moisture and suppress weeds. Mulching also helps regulate soil temperature, keeping the roots cool in hot weather.
- Fertilizing: Calendula doesn’t require heavy feeding, but a light application of balanced organic fertilizer or compost tea once or twice during the growing season can encourage more blooms.
- Deadheading: To prolong the flowering season, regularly deadhead (remove spent blooms) your calendula plants. This prevents the plant from putting energy into seed production and encourages new flower growth.
Step 5: Harvesting Calendula Flowers
Calendula flowers can be harvested for their medicinal properties or simply to enjoy their beauty in a vase. The flowers are at their peak potency just as they begin to fully open, so this is the best time to harvest for herbal use.
- How to harvest: Use clean scissors or pruners to cut the flower heads just above the first set of leaves. Harvest in the morning after the dew has dried for the best quality flowers.
- Drying: If you’re using calendula for medicinal purposes, you’ll want to dry the flowers. Spread the harvested flowers on a clean surface in a warm, dry location with good airflow. Once the petals are completely dry and crisp, they can be stored in an airtight container for later use.
Step 6: Save Seeds for Next Season
Calendula is a self-seeding plant, meaning it will naturally drop seeds and come back the following year. However, if you want to save seeds to plant in another area or share with friends, it’s easy to collect them.
- How to save seeds: Allow some of the flowers to remain on the plant and develop into seed heads. Once the seed heads are fully dry and brown, gently pull them from the plant. Break open the seed pods and collect the seeds for storage in a cool, dry place until the next planting season.
Common Issues and How to Address Them
Calendula is a hardy plant, but it can occasionally face some challenges in the garden. Here are a few common issues and tips for addressing them:
- Pests: Aphids and whiteflies are common pests that may attack calendula. To keep these pests at bay, use a strong stream of water to knock them off or apply an organic insecticidal soap.
- Powdery Mildew: In humid or overly shaded conditions, calendula may develop powdery mildew on its leaves. To prevent this, ensure your plants have good air circulation and avoid overhead watering.
- Leggy Growth: If your calendula plants become tall and leggy, it may be due to insufficient sunlight. Make sure the plants receive adequate sunlight to maintain compact, bushy growth.
Conclusion
Calendula is a beautiful, versatile, and easy-to-grow flower that offers both aesthetic and practical benefits to your garden. Whether you’re growing it for its medicinal properties, attracting pollinators, or simply adding a pop of color to your outdoor space, calendula is a rewarding plant to cultivate.
By following these simple steps, you can successfully grow calendula from seed and enjoy its vibrant blooms throughout the season. Don’t hesitate to give this amazing flower a place in your garden—you’ll be rewarded with a continuous supply of blossoms, whether for herbal remedies, natural beauty products, or just for their radiant charm.
