How many days after sowing do flower seeds germinate?

Flower seeds, that is, the seeds of flowers, are one of the important ways of plant reproduction. Different flower seeds vary in shape, size and colour and can be sown to create new plants. So how many days after sowing do flower seeds germinate? Let’s take a look with the editor below.

1. How many days does it take for flower seeds to germinate after sowing?

1. Quick-germinating seeds: These seeds usually start to germinate within 5 to 10 days after sowing. For example, vegetable seeds such as peas, gourds, and alfalfa, as well as some flower seeds such as petunias, snapdragons , and cosmos, are all fast-germinating seeds.

2. Seeds with medium germination speed: This type of seeds takes a little longer to germinate, and usually begins to germinate in about 10 to 21 days. Including flower seeds such as zinnia, cornflower, carnation, tulip, sunflower , etc.

3. Slow-germinating seeds: Some flower seeds germinate slowly and may take weeks or even months to grow into seedlings. For example, seeds of allium , some perennial flowers or tropical plants, and seeds that need a period of low temperature treatment to break dormancy. In addition, some large seeds, such as iron tree, kapok, etc. and hard-shelled seeds, such as lotus and water lily, are also slow-germinating seeds.

2. Flower seed sowing method

1. Choose potting soil

Choose an appropriate container for planting seeds, such as a pot, planting box or seedbed. The container should have adequate drainage holes to prevent water accumulation, which can cause the seeds to rot. Prepare fertile, loose and well-drained soil. You can use a pre-mixed flower soil, or make your own soil mix suitable for growing flower seeds. Add an appropriate amount of organic matter to the soil to improve soil quality and provide nutrients.

2. Seed treatment

Some flower seeds require special treatment before sowing, such as refrigeration, soaking or scratching the seed coat to promote germination. Check the instructions on the seed package to see if pretreatment is necessary. Before sowing, water the soil thoroughly and leave it for a while to allow the water to penetrate completely.

3. Planting seeds

Choose the appropriate sowing method based on the size and growth habits of the seeds. Small seeds can be sown directly on the soil surface, while larger seeds need to be sown at a certain depth. After sowing, lightly cover the seeds with loose soil or fine sand to avoid too thick a covering layer that affects germination.

4. Watering to keep moist

After planting, lightly mist with water using a spray bottle or watering can to keep the soil moist but not too wet. Avoid using too much water flow, which can wash away the seeds or disrupt their location. In the early stage of sowing, you can cover it with a layer of plastic wrap or plastic film to keep it moist, but you need to pay attention to regular ventilation to prevent the seeds from getting moldy due to lack of oxygen.

The above is an introduction to how many days it takes for flower seeds to germinate after sowing. The germination time after sowing varies depending on many factors such as flower type, seed freshness, seed treatment method, soil conditions, temperature, humidity and light.
