When is the best time to sow zinnia seeds?

Zinnia seed sowing time

Zinnias are usually sown in the spring of each year, specifically between March and April. The climate and temperature during this period are most suitable, and the growth of the plants will be better. However, if there is sufficient light, sowing can also be done in advance.

Zinnia seed planting method and steps

1. Seeds: When sowing zinnias, you need to choose healthy and plump seeds, preferably those harvested in the same year. They need to be disinfected before sowing. Put the seeds in potassium permanganate solution and soak them for 30 minutes before taking them out and drying them.

2. Soil: Zinnia does not have very high requirements for the soil for planting, but if you want it to germinate and grow faster, it is best to use loose, breathable, and well-drained soil. You can prepare it yourself, but it needs to be sterilized before use.

3. Sowing: Spread the prepared zinnia seeds evenly in the soil with reasonable planting spacing. Then cover them with a thin layer of soil and sprinkle water appropriately to keep the soil moist, which can promote germination.

4. Maintenance: After sowing, the temperature of zinnia seeds needs to be kept between 20-23 degrees, and there must be sufficient sunlight. They will germinate in about 20-25 days, and then they need to be placed in a well-ventilated place for maintenance.
