Vinca Plant Seeds: Guide to Storing, Sowing and Germination

Vinca plants are a popular choice for gardeners due to their beautiful, long-lasting blooms in shades of pink, purple, white and red. If you’re interested in growing Vinca plants from seed, it’s important to know how to properly store and sow the seeds for the best germination rates. In this guide, we’ll cover everything you need to know about Vinca plant seeds.

Storing Vinca Plant Seeds

Before you can consider sowing Vinca plant seeds, you’ll need to make sure that you have viable seeds. Vinca plant seeds can be stored for several years if they’re kept in a cool, dark and dry place. The ideal temperature for storing Vinca seeds is between 32-41°F (0-5°C). A refrigerator is a great place to store Vinca plant seeds.

It’s important to keep Vinca plant seeds dry as moisture can cause them to rot or mold. You may want to store your seeds in airtight containers or ziplock bags with desiccant packets to absorb any excess moisture.

Sowing Vinca Plant Seeds

Vinca plant seeds can be sown indoors or outdoors depending on your preference and climate. If you live in an area with a short growing season or cold winters, starting your Vinca seeds indoors can give them a head start and increase their chances of germinating successfully.

To sow Vinca plant seeds indoors:

1. Fill small pots or seed trays with a well-draining potting soil.
2. Moisten the soil slightly.
3. Place 1-2 Vinca seeds on top of the soil.
4. Cover the seeds with a thin layer of soil.
5. Water the soil gently.
6. Place the pots or trays in a warm and bright location but out of direct sunlight.
7. Keep the soil moist but not waterlogged.

Vinca plant seeds typically germinate in 10-14 days. Once the seedlings have grown to a few inches tall, you can transplant them into larger pots or outdoors.

To sow Vinca plant seeds outdoors:

1. Choose a well-draining area with full sun or partial shade.
2. Work the soil to a fine texture and remove any debris and rocks.
3. Scatter the Vinca seeds evenly over the soil surface.
4. Cover the seeds with a thin layer of soil.
5. Water the soil gently.
6. Keep the soil moist but not waterlogged.

Germinating Vinca Plant Seeds

Vinca plant seeds require warmth and moisture for successful germination. The ideal temperature for Vinca seed germination is between 68-77°F (20-25°C).

If you’re starting your Vinca seeds indoors, you may want to use a heat mat to keep the soil warm. You can also cover the pots or trays with plastic wrap to create a humid environment.

Once your Vinca seeds have germinated, you’ll need to provide them with plenty of light. If you’re growing them indoors, place them near a sunny window or under grow lights.
