How to sow calendula

Sowing time

Calendula is usually sown in late September . Before sowing, the soil must be disinfected and exposed to the sun for a few days so that there are no diseases or insects, which is more conducive to the growth of calendula.

Seed treatment

Before planting, the seeds must be germinated by soaking them in warm water for 3 to 10 hours until they absorb water and swell. This operation can be omitted for some very common seeds that are easy to germinate, but to increase the germination rate of calendula, appropriate soaking is required.

Sowing method

For tiny seeds that are difficult to pick up with your hands or other tools, you can wet one end of a toothpick with water and stick the seeds one by one on the surface of the substrate, covering the substrate to a thickness of 1 cm.

Then put the flowerpot for sowing into water. The depth of the water should be 1/2 to 2/3 of the height of the flowerpot. Let the water slowly seep up to avoid washing the seeds away.

Post-sowing care

After sowing in autumn, to avoid cold waves and low temperatures, you can wrap the flower pots in plastic bags to keep them warm and moist. After the seedlings emerge from the soil, remove the film and allow the seedlings to receive sunlight before 9 am or after 3 pm every day, otherwise the seedlings will grow very weakly.

After the seeds have fully germinated, they can be thinned out appropriately, leaving a certain distance between each plant, and pulling out the seedlings that are growing poorly. When most of the seedlings have grown more than 3 leaves, they can be planted in pots.
