Dahlia is a beautiful flowering plant that is popular among gardeners because of its vibrant colors and long blooming season. It comes in many different varieties, each with unique features and growth requirements. If you are looking to grow dahlias, then you need to know how to store, sow and germinate their seeds. In this article, we will provide you with a guide to help you get started.

Storing Dahlia Seeds

Storing dahlia seeds is essential if you want to plant them later on. Here are some steps to follow when storing your dahlias seeds:

  1. Wait for the flowers to die off – Once the flowers have died off and the petals have fallen, the seed pods will start to develop.

  2. Harvest the seed pods – Cut the seed pods from the plant once they have turned brown and started to dry out.

  3. Dry the seed pods – Place the seed pods in a dry and well-ventilated area for several weeks. Once the pods are completely dry, they will open up, revealing the seeds inside.

  4. Store the seeds – Store the seeds in a cool and dry place, away from direct sunlight or moisture.

Sowing Dahlia Seeds

Once you have stored your dahlia seeds properly, it’s time to sow them. Here are some steps to follow:

  1. Choose a pot – Choose a pot that is large enough for your dahlia seedlings. Make sure that it has drainage holes at the bottom.

  2. Fill the pot with soil – Fill the pot with soil up to about 1 inch below the rim.

  3. Sow the seeds – Sow the seeds on top of the soil, spacing them about 1 inch apart.

  4. Cover the seeds – Cover the seeds with a thin layer of soil, about 1/8 inch deep.

  5. Water the soil – Water the soil gently, making sure not to disturb the seeds.

  6. Place the pot in a warm and bright spot – Place the pot in a warm and bright spot, but away from direct sunlight.

  7. Wait for the seeds to germinate – Germination can take anywhere from 5 to 14 days. Once the seedlings have grown a few leaves, you can transplant them into individual pots or in your garden.

Germinating Dahlia Seeds

If you want your dahlia seeds to germinate successfully, you need to provide them with the right conditions. Here are some factors to consider:

  1. Temperature – Dahlia seeds need warm temperatures to germinate. Ideally, the soil temperature should be between 70°F and 75°F.

  2. Moisture – Dahlia seeds need consistent moisture to germinate. Make sure that the soil is moist but not waterlogged.

  3. Light – Dahlia seeds do not require light to germinate, but they need bright light once they have sprouted.

  4. Soil – Dahlia seeds grow best in well-draining soil that is rich in organic matter.
