Propagation of Sweet Alyssum
Sweet Alyssum can be easily propagated from seeds, making it a popular choice for gardeners looking to add fragrance and delicate blooms to their landscapes. Here’s how to propagate and sow Sweet Alyssum:
If you have existing Sweet Alyssum plants in your garden, you can collect seeds from spent flowers once they have dried on the plant. Simply wait for the flower heads to dry out and turn brown, then gently remove them and collect the small seeds from inside.
Alternatively, you can purchase Sweet Alyssum seeds from nurseries or garden centers. Choose high-quality seeds from reputable sources for best results.
Sweet Alyssum seeds are tiny and should be sown directly into the garden bed or containers where you want them to grow. Prepare the soil by loosening it and removing any debris. Rake the soil to create a fine, level surface.
Sow Sweet Alyssum seeds in early spring after the last frost has passed. They prefer cool temperatures for germination and early growth.
Since the seeds are small, they should be sown very shallowly. Gently press the seeds into the soil surface or sprinkle them lightly over the prepared area.
If sowing in rows, space the seeds about 6 to 12 inches apart. For mass plantings or containers, scatter the seeds evenly across the surface.
After sowing, water the soil lightly to settle the seeds in place. Keep the soil consistently moist but not waterlogged during the germination period, which typically takes 7 to 14 days.
Once the seedlings emerge and develop their first true leaves, thin them to the desired spacing. This ensures proper air circulation and prevents overcrowding, which can lead to disease.
Sweet Alyssum is relatively low-maintenance but benefits from regular watering and occasional fertilization to promote continuous blooming.
By following these steps, you can easily propagate and sow Sweet Alyssum seeds to enjoy their charming blooms and sweet fragrances in your garden or containers.
Water Requirement
During the establishment period, which is typically the first few weeks after sowing seeds or transplanting seedlings, keep the soil consistently moist but not waterlogged. Water the plants gently to prevent disturbing the seeds or young roots. Once Sweet Alyssum plants are established, they still require regular watering, especially during dry spells or hot weather.
Fertilizer Requirement
Sweet Alyssum is not a heavy feeder and generally grows well in average to fertile soil. Before planting Sweet Alyssum, incorporate organic matter such as compost into the soil to improve fertility and soil structure. This provides a good foundation for the plants to thrive.
If growing Sweet Alyssum in containers, use a balanced, water-soluble fertilizer diluted to half-strength and apply it every 2-4 weeks during the growing season. Container plants may require more frequent fertilization than those grown in the ground due to the leaching of nutrients from watering.
