How to sow and raise seedlings of flowers

Preparation before sowing flowers

1. Soaking seeds

Seeds with thinner seed coats can be soaked in cold water, those with thicker seed coats can be soaked in warm or hot water, and very small seeds do not need to be soaked.

2. Prepare the seedling box/pot

The advantages of seedling pots are saving seeds, uniform nutrients, neat germination, easy transplanting, and convenience for counting seed germination rates. When sowing seeds directly in the ground, the temperature and humidity of the soil are difficult to control, and the soil may contain microorganisms that are not conducive to the germination and growth of seeds.

3. Seedling medium

Choose a soil substrate that is loose, breathable, good at retaining fertilizer and water, and clean. You can mix peat soil, coconut coir, vermiculite, etc.

4. Potting

After mixing the substrate evenly, put it into the pot. There is no need to compact it, just level the soil surface.

5. Watering

Control the amount of water and water the potting soil thoroughly. After watering, you can apply fungicides to disinfect the soil.

Flower sowing process

1. Seeding density

When sowing in hole pots, sow 1 or more seeds per hole; when sowing in seedling pots, sow 1-2 seeds per square meter.

2. Planting seeds

When the flower seeds are large, they can be evenly scattered on the substrate, or they can be sown in rows or spots. When the flower seeds are small, they can be mixed evenly with clean fine sand and then sown.

3. Sowing depth and soil covering

The sowing depth is determined by the seed size and the light requirement for seed germination. Generally speaking, the sowing depth of seeds is 2-3 times the seed diameter.

4. Water spray

After sowing and covering the soil, water with a fine mist sprinkler and make sure it is watered thoroughly.

5. Cover

Covering the seed tray with glass, mulch or plastic film can maintain air humidity and keep the air warm in winter. In the summer when the temperature is high, the film does not need to be covered, but when the film is covered, ventilation must be maintained on both sides.

Management of flowers after sowing

1. Temperature

Generally speaking, the germination temperature of seeds is between 20-25 degrees, and appropriate temperature environment should be provided according to the requirements of the flower variety.

2. Humidity

Add less water when raising seedlings in winter, and add water at any time according to actual conditions when raising seedlings in summer.

3. Lighting

Generally speaking, seeds germinate easily under light conditions. If the seeds do not receive light after germination, the seedlings will grow too tall.

4. Remove the covering

After the seeds germinate, the covering should be removed in time, but the temperature of the substrate should still be maintained to allow the ungerminated seeds to shed their shells.

5. Transplantation

When the seedlings grow to a certain size, they must be transplanted and cultivated in time, otherwise the seedlings will grow too tall or production will be delayed.
