Nasturtiums are beautiful, vibrant flowers that not only add a pop of color to gardens but are also edible, making them a fantastic choice for both aesthetics and culinary adventures. Growing nasturtium from seeds is a rewarding and straightforward process, perfect for novice gardeners. In this article, we'll explore how to grow nasturtium seeds effectively, with added insights and tips to ensure a successful growing experience.
Understanding Nasturtium
Before diving into the growing process, it's essential to know a bit about nasturtiums. They are annual plants belonging to the Tropaeolum family, known for their bright orange, red, or yellow flowers and round leaves. Nasturtiums thrive in various conditions and are often used in borders, containers, or as ground cover.
What You’ll Need:
- Nasturtium seeds: Choose from a variety of types such as 'Empress of India' or 'Alaska Mix.'
- Potting soil: High-quality potting mix with good drainage.
- Containers or garden space: Depending on your preference, nasturtiums can be grown in pots or directly in the ground.
- Watering can: For consistent moisture.
- Sunlight: A location that gets at least 6 hours of sunlight daily.
Step-by-Step Guide to Growing Nasturtium Seeds
1. When to Plant Nasturtium Seeds
Nasturtium seeds can be sown directly into the soil after the last frost or started indoors 4-6 weeks before the last frost date. When starting outdoors, the soil temperature should be around 60°F (15°C) for optimal germination.
2. Prepare the Soil
Nasturtiums prefer well-draining, slightly poor soil. Rich soil can lead to more foliage than flowers. To prepare your planting area, loosen the soil and mix in some compost, which will provide nutrients without making the soil too rich.
3. Planting the Seeds
- Direct sowing: If you choose to plant directly in the garden, sow seeds 1/2 inch deep and space them 10-12 inches apart.
- Indoor sowing: If starting indoors, plant seeds in peat pots filled with potting soil. Sow the seeds about 1/2 inch deep.
4. Watering
After planting, water the seeds thoroughly but avoid overwatering. Nasturtium seeds require consistent moisture until they germinate, which typically takes 7-10 days. Once established, these plants are quite drought-tolerant.
5. Providing Sunlight
Nasturtiums thrive in full sun, so ensure they receive at least 6 hours of direct sunlight each day. However, they can tolerate partial shade in hotter climates.
6. Care and Maintenance
Once your nasturtiums are growing, ensure you:
- Water them regularly, especially during dry spells.
- Pinch off spent flowers to encourage more blooms.
- Watch for pests such as aphids and take action if necessary, using organic methods like insecticidal soap.
7. Harvesting Seeds and Flowers
Both the flowers and leaves are edible and can be used in salads, while the seeds can be harvested and used as a substitute for capers. To harvest seeds, wait until they turn brown and dry on the plant.
Additional Tips for Success
-
Companion Planting: Nasturtiums are known to deter pests, making them great companions for vegetable gardens. Consider planting them near tomatoes, cucumbers, or other plants susceptible to aphids and beetles.
-
Varieties: Explore different varieties of nasturtium seeds, as each has unique colors and growth habits. 'Tall' varieties are excellent for climbing trellises, while 'dwarf' types are ideal for borders or container gardening.
-
Season Extension: If you live in cooler climates, consider using row covers to extend the growing season, allowing nasturtiums to flourish even in chilly weather.
