As a gardening and landscaping expert, I can confidently say that calendula seeds do not require any treatment before sowing. Unlike some other seeds that may benefit from soaking or stratification, calendula seeds are ready to be planted directly into the garden or raised in trays for later transplantation.
Soaking seeds before planting is a common practice for certain plant species. This process involves placing the seeds in water for a specific period of time to soften the seed coat and promote germination. However, calendula seeds do not have a particularly hard or tough seed coat, so soaking is unnecessary.
In fact, soaking calendula seeds may actually be detrimental. Excessive moisture can lead to seed rot or fungal growth, which can impede or prevent germination altogether. Therefore, it is best to avoid soaking calendula seeds and instead plant them directly into the soil.
When it comes to sowing calendula seeds, you have two options: direct sowing or raising seedlings in trays. Direct sowing involves planting the seeds directly into the desired location in your garden. This method is simple and convenient, especially if you have a large area to cover.
On the other hand, starting calendula seedlings in trays or containers allows for more control over their growth and development. This method is particularly useful if you want to get a head start on the growing season or if you have limited space in your garden. By starting the seeds indoors, you can ensure optimal conditions for germination and early growth before transplanting them to their permanent location.
To start calendula seedlings indoors, fill seed trays or containers with a well-draining seed-starting mix. Moisten the soil and sow the seeds by gently pressing them into the surface, ensuring they are not buried too deep. Cover the trays with a plastic dome or plastic wrap to create a mini greenhouse effect and maintain moisture.
Place the trays in a warm and well-lit area, such as a sunny windowsill or under grow lights. Calendula seeds typically germinate within 7 to 14 days, depending on the conditions. Once the seedlings have developed their second set of true leaves, they can be transplanted into the garden.
Before transplanting, harden off the seedlings by gradually exposing them to outdoor conditions over the course of a week. This helps them adjust to the differences in temperature, light, and wind. Once hardened off, plant the seedlings in well-prepared soil, ensuring they are spaced adequately to allow for proper growth and airflow.
Calendula seeds do not require any pre-sowing treatment such as soaking or stratification. They can be directly sown into the garden or started indoors as seedlings. Soaking calendula seeds is unnecessary and may even be detrimental. By following these guidelines, you can successfully grow calendula plants from seed and enjoy their vibrant blooms in your garden.
