Shark Tooth Plant Seeds:
Guide to Storing, Sowing and Germination

Shark Tooth Plant (Dichondra argentea), also known as Silver Ponyfoot, is a unique and attractive groundcover plant with small, tooth-shaped leaves. Its low-growing habit and silver-green foliage make it an excellent choice for borders, rock gardens, or as a filler between stepping stones. Growing Shark Tooth Plants from seeds can be a rewarding experience, and this guide will walk you through the steps of storing, sowing, and germinating these fascinating seeds.

Storing Shark Tooth Plant Seeds

Before you can start sowing Shark Tooth Plant seeds, it’s essential to store them properly to maintain their viability. Here’s a step-by-step guide on how to store Shark Tooth Plant seeds:

1. Harvesting: Collect the mature seeds from the plant when they are dry and brown. You can do this by gently shaking the seed heads over a container or by cutting the seed heads off with pruning shears.

2. Drying: Spread the collected seeds in a single layer on a paper towel or a clean, dry surface. Allow them to air dry for about a week in a cool and well-ventilated area. Make sure there is no moisture present, as it can lead to mold or rot.

3. Cleaning: Once the seeds are dry, remove any debris or chaff by gently rubbing them between your fingers or using a fine-mesh sieve. This step ensures that you only store clean and viable seeds.

4. Storage container: Place the cleaned seeds in an airtight container, such as a glass jar or a resealable plastic bag. It’s recommended to label the container with the date and seed variety for easy identification.

5. Storage conditions: Store the container in a cool, dry, and dark place. A temperature between 35-50°F (2-10°C) is ideal for maintaining seed viability. Avoid storing them in areas prone to temperature fluctuations or high humidity, as it can reduce seed quality.

By following these steps, you can store your Shark Tooth Plant seeds for up to two years while maintaining their germination potential.

Sowing Shark Tooth Plant Seeds

Once you are ready to sow your Shark Tooth Plant seeds, it’s important to provide them with the right conditions for successful germination. Here’s how to sow Shark Tooth Plant seeds:

1. Soil preparation: Prepare a well-draining potting mix by combining equal parts of peat moss or coconut coir and perlite or vermiculite. This mixture will ensure good drainage and aeration for the developing seedlings.

2. Containers: Fill shallow seed trays or individual pots with the prepared potting mix. Alternatively, you can sow the seeds directly in a prepared garden bed with loose soil.

3. Sowing depth: Shark Tooth Plant seeds are tiny, so they should be sown on the soil surface without covering them. Gently press the seeds into the soil to ensure good contact.

4. Moisture: Mist the soil surface lightly with water to settle the seeds in place. Avoid overwatering, as excessive moisture can lead to fungal diseases or rotting of the seeds.

5. Covering: To maintain humidity and protect the seeds from drying out, cover the containers with a transparent plastic lid or place them inside a clear plastic bag. This mini greenhouse effect will create a favorable environment for germination.

6. Germination temperature: Place the containers in a warm location with a temperature between 65-75°F (18-24°C). A heat mat can be used to provide consistent warmth if necessary.

7. Lighting: Shark Tooth Plant seeds require indirect light for germination. Place the containers in a well-lit area, but avoid direct sunlight, as it can cause overheating or drying of the soil.

8. Germination period: Shark Tooth Plant seeds usually germinate within 7-14 days under optimal conditions. However, germination can take longer, so be patient and maintain consistent moisture throughout the process.

Germination and Care

Once the Shark Tooth Plant seeds have germinated, it’s important to provide them with proper care to ensure healthy growth. Here are some tips for germination and care:

1. Remove covering: Once the seedlings emerge, remove the plastic cover or bag to allow better airflow and prevent damping-off diseases.

2. Lighting: Provide bright, indirect light for the seedlings. If growing indoors, place them near a south-facing window or use artificial grow lights.

3. Watering: Keep the soil evenly moist but avoid overwatering. Allow the top inch of soil to dry out slightly before watering again.

4. Transplanting: When the seedlings develop their second set of true leaves, they can be transplanted into individual pots or spaced 6-8 inches apart in the garden bed.

5. Fertilizing: Feed the seedlings with a balanced liquid fertilizer diluted to half strength every two weeks during the growing season.

6. Maintenance: Trim or mow the Shark Tooth Plant regularly to encourage compact growth and maintain its shape as a groundcover.

By following these guidelines, you can enjoy a beautiful carpet of Shark Tooth Plants in your garden or landscape.

In conclusion, growing Shark Tooth Plants from seeds can be an exciting and rewarding experience. By properly storing, sowing, and caring for these unique seeds, you can successfully germinate them and enjoy their beauty as a groundcover plant. So why not give it a try? Happy gardening!
