Mirror Plant Seeds:
Guide to Storing, Sowing and Germination

Mirror plants (Coprosma repens) are popular ornamental shrubs known for their glossy, mirror-like leaves. These plants can add a touch of elegance and beauty to any garden or landscape. If you’re lucky enough to have mirror plants in your garden, you may be interested in storing, sowing, and germinating their seeds to propagate new plants. In this guide, we’ll walk you through the process of handling mirror plant seeds to ensure successful propagation.

Storing Mirror Plant Seeds

Before we dive into the details of sowing and germinating mirror plant seeds, it’s important to understand how to properly store them. Mirror plant seeds are typically produced in small berries that turn from green to orange or red as they ripen. Once the berries have reached their mature color, they can be harvested.

To harvest mirror plant seeds, gently pluck the berries from the plant when they are fully ripe. It’s important to note that mirror plant seeds have a relatively short viability period, so it’s best to sow them as soon as possible after harvesting. However, if you’re unable to sow them immediately, you can store them for a short period.

To store mirror plant seeds, carefully remove the fleshy pulp from the berries and rinse them thoroughly with water. This will help prevent any fungal growth during storage. Once clean, spread the seeds out on a paper towel or a mesh screen in a well-ventilated area. Allow them to air dry for a few days until they become hard and brittle.

After drying, transfer the seeds into an airtight container such as a ziplock bag or glass jar. It’s essential to keep the container in a cool, dark place with stable humidity levels. If stored properly, mirror plant seeds can remain viable for up to six months.

Sowing Mirror Plant Seeds

When the time comes to sow mirror plant seeds, you have a few options. You can choose to sow them directly into the ground or start them in containers indoors. Both methods can be successful, so it ultimately depends on your personal preference and the conditions in your garden.

Sowing Directly into the Ground

If you decide to sow mirror plant seeds directly into the ground, it’s crucial to choose a suitable location. Mirror plants prefer well-draining soil that is rich in organic matter. Clear any weeds or debris from the area before sowing.

To sow the seeds, create small holes in the soil about 1/4 inch deep. Space the holes at least 12 inches apart to allow room for growth. Place one seed in each hole and cover it lightly with soil. Water the area gently to ensure good seed-to-soil contact.

Starting Seeds Indoors

If you prefer to start mirror plant seeds indoors, you’ll need containers such as seed trays or pots. Fill the containers with a well-draining potting mix and moisten it slightly before sowing the seeds.

Sow one seed per container by placing it on top of the soil and lightly pressing it down. Cover the seed with a thin layer of soil and mist it with water to keep it moist.

To provide optimal conditions for germination, cover the containers with plastic wrap or place them in a clear plastic bag to create a mini greenhouse effect. Keep them in a warm location with temperatures around 70-75°F (21-24°C).

Germinating Mirror Plant Seeds

Mirror plant seeds typically germinate within 2-4 weeks if provided with suitable conditions. During this time, it’s important to maintain consistent moisture levels without overwatering.

For direct-sown seeds, water the area regularly to keep the soil moist but not waterlogged. In contrast, for indoor-started seeds, mist them with water as needed to keep the soil slightly damp. Avoid saturating the soil, as this can lead to rot.

As the seeds germinate, you’ll notice small seedlings emerging from the soil. At this stage, it’s crucial to provide adequate light to ensure healthy growth. Place the seedlings in a bright location, such as a sunny windowsill or under grow lights. Aim for at least 6-8 hours of direct sunlight per day.

Once the seedlings have developed a few sets of true leaves and are strong enough to handle, they can be transplanted into larger pots or directly into the garden. Be gentle when transplanting to avoid damaging the delicate root system.

Conclusion

Storing, sowing, and germinating mirror plant seeds can be a rewarding experience that allows you to propagate new plants and expand your garden. By following the guidelines outlined in this guide, you can increase your chances of successful seed propagation. Whether you choose to sow them directly into the ground or start them indoors, mirror plant seeds have the potential to grow into beautiful mirror-like shrubs that will enhance the aesthetic appeal of your garden.
