Nasturtiums are vibrant, easy-to-grow plants that add a splash of color to any garden. Propagating them from seeds is a simple and rewarding process. This guide will walk you through the steps to successfully grow nasturtiums from seeds and create a lush, colorful display in your garden.
Gathering Your Materials
- Fresh nasturtium seeds
- Garden soil or potting mix
- Seed trays or small pots
- Watering can or spray bottle
- Mulch (optional)
Preparing the Seeds
Start by selecting healthy, mature seeds. Nasturtium seeds are large and easy to handle. Soaking the seeds in water for 12-24 hours before planting can help speed up germination, especially if the seeds are old or hard.
Planting the Seeds
Fill your seed trays or pots with moist soil or potting mix. Plant the seeds about 1 inch deep and space them a few inches apart. Cover lightly with soil and gently water to settle the soil around the seeds.
Caring for Your Nasturtiums
Place the trays or pots in a sunny location. Nasturtiums thrive in full sun but can tolerate partial shade. Keep the soil consistently moist but not waterlogged. As the seedlings grow, thin them out to give each plant enough space to develop.
Transplanting and Growing
Once the seedlings have developed at least two sets of true leaves and the weather is warm enough, transplant them into your garden. Choose a sunny spot with well-draining soil. Space the plants about 10-12 inches apart to allow for growth and airflow.
Additional Tips for a Lush Display
- Mulch around the plants to retain moisture and suppress weeds.
- Regularly water during dry spells, especially after transplanting.
- Fertilize lightly with a balanced fertilizer if needed.
- Encourage climbing by providing trellises or supports if you want vertical growth.
With proper care, nasturtiums will flourish, providing vibrant blooms and edible leaves that add flavor to salads. Propagating from seeds is a cost-effective way to enjoy these beautiful plants year after year.
