When to sow petunias

1. When

The temperature suitable for germination of this type of plant is about 18-25℃, and the most suitable temperature for its growth is 22-34℃. As long as the maintenance temperature is appropriate, new buds will generally sprout in 3-7 days. Therefore, if sowing is done in a natural climate, it is recommended to sow in the spring when the temperature warms up every year. The seeds sown at this time will be able to bloom in the summer. Of course, if the maintenance conditions are in place, you can also choose to plant in advance.

2. Precautions

Flower soil: It is recommended to use mixed soil that has been sterilized at high temperature. The mixed soil can be prepared with garden soil, leaf mold and a little sand. There is no need to turn the soil after sowing. Just press it lightly and place it in a cool and ventilated place, and it will germinate.

Watering: Before sowing, the flower soil needs to be watered thoroughly. After sowing, ensure the moisture of the seedlings to avoid affecting the normal germination of the plants due to the flower soil being too dry.
