Eryngium, commonly known as sea holly, is a genus of herbaceous perennial plants that are valued for their unique, spiky flowers and attractive foliage. Growing eryngium from seeds is a rewarding and straightforward process that can be enjoyed by gardeners of all skill levels. This comprehensive guide will provide you with all the necessary information and tips to successfully sow and grow eryngium plants from seeds.
Selecting the Right Seeds
The first step in sowing eryngium seeds is to select high-quality seeds from a reputable supplier. Look for seeds that are fresh and have a high germination rate. You can also choose from a variety of eryngium species, each with its own unique characteristics and growing requirements.
Preparing the Soil
Before sowing the seeds, it is important to prepare the soil properly. Eryngium plants prefer well-drained, sandy soil with a pH of 6.5 to 7.0. If your soil is heavy or clay-like, amend it with organic matter such as compost or peat moss to improve drainage.
Sowing the Seeds
Eryngium seeds can be sown indoors or outdoors, depending on your climate.
Indoor Sowing:
- Sow the seeds in a seed tray or pot filled with a well-draining seed starting mix.
- Cover the seeds lightly with soil and gently firm them down.
- Keep the soil moist and provide bottom heat of 65-70°F (18-21°C).
- The seeds will germinate in 14-21 days.
Outdoor Sowing:
- Sow the seeds directly in the garden in the fall or early spring.
- Choose a sunny location with well-drained soil.
- Scatter the seeds on the surface of the soil and rake them in lightly.
- Water the seeds and keep the soil moist until germination.
Caring for Eryngium Seedlings
Once the eryngium seeds have germinated, they will need to be cared for properly to ensure healthy growth.
Light: Eryngium seedlings require plenty of sunlight. Place them in a sunny window indoors or move them outdoors as soon as possible.
Water: Water the seedlings regularly, but avoid overwatering. Allow the soil to dry out slightly between waterings.
Fertilizer: Fertilize the seedlings every few weeks with a balanced liquid fertilizer.
Transplanting Eryngium Seedlings
When the eryngium seedlings have developed their first set of true leaves, they are ready to be transplanted into individual pots or into the garden.
Transplanting Indoors:
- Harden off the seedlings by gradually exposing them to outdoor conditions for a few hours each day.
- Transplant the seedlings into individual pots filled with a well-draining potting mix.
- Water the seedlings thoroughly and place them in a sunny location.
Transplanting Outdoors:
- Choose a sunny location with well-drained soil.
- Dig holes that are twice the width of the root ball.
- Place the seedlings in the holes and backfill with soil.
- Water the seedlings thoroughly and mulch around them to retain moisture.
Growing Eryngium Plants
Once the eryngium plants are established, they are relatively easy to care for.
Watering: Water the plants regularly, especially during hot, dry weather.
Fertilizer: Fertilize the plants every few weeks with a balanced liquid fertilizer.
Pruning: Remove spent flower heads to encourage new growth.
Eryngium Pests and Diseases
Eryngium plants are generally resistant to pests and diseases, but they can be susceptible to aphids, spider mites, and powdery mildew.
Aphids: Small, green insects that feed on the sap of plants.
Spider Mites: Tiny, web-spinning pests that can cause leaves to turn yellow and drop.
Powdery Mildew: A fungal disease that causes a white, powdery growth on leaves.
Control these pests and diseases by using insecticidal soap or neem oil.
