When is the best time to sow petunia seeds?

Petunia seed sowing time

Petunia seeds have a relatively good germination ability, so as long as the temperature is right, they can be sown all year round. However, relatively speaking, the most suitable season is around October to November in autumn. The climate temperature at that time is most suitable for seed germination, and they will germinate about 3-7 days after sowing.

Petunia seed planting method and steps

1. Potting soil: Before sowing petunias, you need to prepare the potting soil. The soil used must be loose and breathable. You can mix leaf mold, garden soil and river sand. This way, the soil will have better drainage. The planting pots must also be loose and breathable.

2. Seeds: Petunia seeds can be purchased in specialty stores or picked by yourself. However, you must choose mature, plump and healthy seeds so that the germination rate will be higher and they can grow quickly after planting.

3. Sowing: When sowing petunias, you need to spread the seeds evenly on the surface of the soil. There is no need to cover the soil. Just expose the seeds directly to the air. In the later stage, you need to water them in time and then cover them with a layer of plastic wrap.

4. Maintenance: After planting, the potting soil needs to be moved to a place with good ventilation. There must be a good ventilation environment. It can be transplanted when 2-3 pairs of leaves grow after germination.
