Discover expert tips and tricks for nurturing your dogwood seedlings into thriving trees. Perfect for gardening enthusiasts of all levels.

Why Grow Dogwood from Seed?

Dogwood trees ( Cornus species) are prized for their stunning blooms, vibrant fall foliage, and interesting bark textures. While purchasing established saplings is an option, growing dogwood from seed offers a rewarding and unique gardening experience. It's also a more cost-effective method, especially if you're planting multiple trees. However, it's important to note that growing dogwood from seed requires patience; it's a slower process than planting a seedling.

Collecting Dogwood Seeds

The first step in growing dogwood from seed is collecting viable seeds. This typically involves waiting until the dogwood berries ripen fully in late summer or early fall. The berries will turn a deep red or dark blue-black, depending on the dogwood variety.

Tips for Seed Collection:

Choose healthy berries: Select ripe, plump berries from healthy, disease-free trees.
Collect in dry weather: Avoid collecting seeds after rainfall, as wet berries are more prone to rotting.
Multiple sources: Collect seeds from multiple trees to increase genetic diversity in your seedlings.

Preparing Dogwood Seeds for Germination: Stratification

Dogwood seeds require a process called stratification before they will germinate. Stratification mimics the natural conditions the seeds would experience over winter. It breaks down the seed coat and allows the embryo to begin growing.

What is stratification?

Stratification is a crucial step that involves exposing the seeds to cold, moist conditions for a period of time. This process breaks down the seed's hard outer shell and encourages germination. There are two main methods:

Method 1: Cold Stratification (Recommended):

Clean the seeds: Remove the pulp from the berries and rinse the seeds thoroughly.
Mix with moist medium: Combine the seeds with a damp medium such as vermiculite, peat moss, or sand. The mixture should be moist but not soggy.
Store in a cool location: Place the mixture in a sealed container or plastic bag and store it in a refrigerator (35-40°F or 2-4°C) for 60-90 days.

Method 2: Warm Stratification (Less Effective):

Prepare seed mix: Mix seeds with a moist medium (as described above).
Warm storage: Place the mixture in a warm location (approximately 70-75°F or 21-24°C) for 30-60 days.
Cold storage: After the warm storage, move the container to the refrigerator (as described in Method 1) for another 60-90 days. This method is less reliable but could still lead to germination.

Sowing Dogwood Seeds

After stratification, it's time to sow your dogwood seeds. The best time for sowing is usually in spring.

How to Sow:

Prepare seed starting mix: Use a well-draining seed starting mix. Avoid using garden soil, as it may contain pathogens.
Sow seeds: Sow the seeds about ¼ inch deep in small pots or seed trays.
Keep moist: Keep the soil consistently moist but not waterlogged.
Provide light: Place the containers in a location that receives bright, indirect light.

Dogwood Seedling Care

Once your dogwood seeds germinate, continue to provide consistent care for healthy growth.

Watering: Water regularly, keeping the soil moist but not saturated. Allow the top inch of soil to dry slightly between waterings.
Fertilizing: Fertilize lightly with a balanced fertilizer once the seedlings have developed a few sets of leaves. Avoid over-fertilizing.
Hardening off: Before transplanting outdoors, gradually acclimate the seedlings to outdoor conditions over a period of several weeks. This process, known as hardening off, helps them adjust to the changes in temperature, sunlight, and humidity.
Transplanting: Transplant the seedlings into larger containers or directly into the garden once they are large enough to handle. This usually occurs after one or two growing seasons. Choose a location with partial shade and well-drained soil.

Troubleshooting

Slow germination: If germination is slow or nonexistent, it might be due to insufficient stratification or poor seed quality.
Damping-off: This fungal disease can kill seedlings. Ensure good air circulation and avoid overwatering.
Pest and disease issues: Monitor for pests and diseases and take appropriate action if necessary.

Growing dogwood from seed is a worthwhile, albeit time-consuming, project. By following these steps and providing proper care, you can successfully cultivate beautiful dogwood trees that will grace your garden for years to come. Remember patience is key, and enjoy the journey of watching your seedlings grow.
