Growing Nasturtium Flowers: A Beginner's Guide
=====================================================
As a gardener, I've always been fascinated by the unique and colorful Nasturtium flowers. Not only are they a delight to behold, but they also have a number of practical uses in the garden and kitchen. In this article, I'll share my experience and tips on how to grow Nasturtium flowers from seed, from sowing to harvest.
Choosing the Right Variety
When selecting a Nasturtium variety, there are several factors to consider. These include the size and shape of the flowers, the color palette, and the growing requirements. Some popular varieties include 'Empress of India', 'Jewel of Africa', and 'Crimson King'. 'Empress of India' is a popular choice for its large, delicate flowers and compact growth habit, while 'Jewel of Africa' offers a more compact and spreading form. 'Crimson King' is a favorite for its deep red flowers and ability to thrive in cooler temperatures.
Sowing the Seeds
Nasturtium seeds are relatively easy to sow, but it's essential to get the timing right. In most regions, it's best to sow Nasturtium seeds in late spring to early summer, when the soil has warmed up to at least 60°F (15°C). You can sow the seeds directly in the ground, or start them indoors 4-6 weeks before the last frost date.
To sow the seeds, follow these steps:
- Fill a seed starting tray or small pots with a well-draining seed starting mix.
- Sow the seeds about 1/8 inch (3 mm) deep and 1-2 inches (2.5-5 cm) apart.
- Water the seeds gently but thoroughly.
- Provide the seedlings with plenty of light, either from direct sunlight or supplemental lighting.
Germination and Growth
Nasturtium seeds typically take 7-14 days to germinate. Once the seedlings emerge, they'll need plenty of light and warmth to grow. Keep the soil consistently moist but not waterlogged, and fertilize the seedlings with a balanced fertilizer once they reach 2-3 inches (5-7.5 cm) tall.
To promote healthy growth, provide the seedlings with the following conditions:
- Full sun to partial shade: Nasturtiums love the sun, but can tolerate some shade.
- Well-draining soil: Nasturtiums prefer a slightly acidic to neutral soil pH (6.0-7.0).
- Consistent moisture: Keep the soil consistently moist, but not waterlogged.
Supporting the Plants
As the Nasturtium seedlings grow, they'll need support to prevent them from flopping over. You can provide support using a trellis, stake, or cage. This will also help to keep the plants upright and encourage vertical growth.
Pest and Disease Management
Nasturtiums are generally a low-maintenance crop, but they can be susceptible to pests and diseases. To manage pests, use natural methods such as introducing beneficial insects or using neem oil. For diseases, use copper-based fungicides or remove infected leaves.
Harvesting and Using Nasturtium Flowers
Nasturtium flowers are a great addition to salads, sandwiches, and other dishes. They can also be used as a garnish or in floral arrangements. To harvest the flowers, simply snip off the individual blooms or remove the entire flower head. Use scissors or pinch off the flowers with your fingers.
Conclusion
Growing Nasturtium flowers is a rewarding experience, and with the right tips and techniques, you can enjoy these beautiful flowers in your own garden. Remember to choose the right variety, sow the seeds at the right time, provide the right conditions, and harvest the flowers at the right moment. Happy gardening!
Additional Tips and Variations
- Companion Planting: Nasturtiums can be used as a companion plant to repel pests and attract beneficial insects. Planting marigolds, calendula, and basil alongside Nasturtiums can enhance their growth and flavor.
- Cultivation: Nasturtiums can be grown in a variety of containers, from small pots to large tubs. They prefer well-draining soil and full sun to partial shade.
- Variation: There are several varieties of Nasturtiums, including 'Jewel of Africa', 'Crimson King', and 'Empress of India'. Each variety has its own unique characteristics and growing requirements.
Common Issues and Solutions
- Yellowing Leaves: Overwatering can cause yellowing leaves in Nasturtiums. Adjust your watering schedule to ensure the soil is consistently moist but not waterlogged.
- Pests: Aphids, whiteflies, and spider mites can infest Nasturtiums. Use neem oil or insecticidal soap to control these pests.
- Diseases: Powdery mildew and leaf spot can affect Nasturtiums. Use copper-based fungicides or remove infected leaves to prevent the spread of disease.
