As a gardening and landscaping expert, I can confidently say that marigold seeds do not require any treatment before planting. This means that soaking the seeds is not necessary for successful germination and growth.
Marigold seeds are relatively easy to handle and sow. They have a hard seed coat that does not need to be scarified or softened through soaking. Soaking seeds is often done for plants with hard seed coats to help speed up the germination process. However, marigold seeds have a natural ability to absorb moisture from the soil and initiate germination without any assistance.
If you choose to sow marigold seeds directly into the garden, there are a few things to keep in mind. Firstly, ensure that the soil is well-draining and rich in organic matter. Marigolds prefer a sunny location, so choose a spot that receives at least 6 hours of direct sunlight per day. Prepare the soil by removing any weeds or debris and loosening it with a garden fork or tiller.
Sow the marigold seeds at a depth of about 1/4 inch (6 mm) in the prepared soil. Space the seeds about 6-8 inches (15-20 cm) apart to allow for proper growth and airflow. Gently press the soil over the seeds to ensure good seed-to-soil contact.
Alternatively, you can start marigold seeds indoors in trays or containers before transplanting them to the garden. This can be advantageous if you want to get a head start on the growing season or if you live in an area with a shorter growing season. Sow the seeds in a well-draining seed starting mix, keeping them moist but not waterlogged. Place the trays or containers in a warm location, such as near a sunny window or under grow lights.
Once the marigold seedlings have developed a few sets of true leaves and are sturdy enough to handle, they can be transplanted to the garden. Harden off the seedlings by gradually exposing them to outdoor conditions over a period of a week or two. This helps them acclimate to the change in environment and reduces the risk of transplant shock.
When planting the marigold seedlings in the garden, dig a hole slightly larger than the root ball and gently place the seedling in the hole. Backfill the hole with soil, firming it gently around the roots. Water the newly transplanted seedlings thoroughly to help them establish in their new location.
Marigold seeds do not require soaking or any other treatment before planting. You can sow them directly into the garden or start them indoors and transplant the seedlings. Regardless of the method you choose, provide them with well-draining soil, ample sunlight, and regular watering for successful growth. Enjoy the vibrant and cheerful blooms of marigolds in your garden!
