Now that you have a better understanding of calendula seeds, let’s explore the optimal time to sow them for a successful growing season.

Determining the Ideal Planting Time

The ideal planting time for calendula seeds depends on your specific climate and the average temperature in your region. Calendula thrives in cooler temperatures, making it a suitable flower to grow in spring and fall in most areas.

If you reside in a region with mild winters and cool springs, you can sow calendula seeds directly in the garden in early spring, as soon as the soil can be worked. This allows the seeds to take advantage of the cool weather and longer days to establish themselves and grow into healthy plants.

In areas with hot summers, it’s best to avoid planting calendula seeds during the peak heat. Instead, wait for the temperatures to cool down in late summer or early fall to sow the seeds. This will provide the plants with ideal growing conditions, avoiding stress from excessive heat.

Keep in mind that calendula seeds germinate best when the soil temperature is around 55-65°F (13-18°C). If the soil is too cold, the seeds may have difficulty sprouting, resulting in poor germination rates. To ensure the right soil temperature, you can use a soil thermometer to monitor the conditions.

Furthermore, if you prefer to start your calendula seeds indoors, you can begin the process 6-8 weeks before the last expected frost date. Start the seeds in small pots or seed trays filled with a well-draining potting mix. Place them in a sunny location or under grow lights and keep the soil consistently moist. Transplant the seedlings into the garden once all danger of frost has passed and the soil has warmed up.

In summary, the ideal planting time for calendula seeds varies depending on your climate. Sow the seeds in early spring in regions with mild winters and cool springs, or wait for late summer or early fall in areas with hot summers. By choosing the optimal planting time, you can ensure the best conditions for your calendula plants to thrive.
