Introduction to Nasturtiums
Nasturtiums (Tropaeolum majus) are annual flowering plants native to South America, particularly Peru and surrounding regions. They belong to the Tropaeolaceae family and are renowned for their vibrant flowers and round, shield-shaped leaves. Nasturtiums are easy to grow and are prized not only for their ornamental beauty but also for their culinary uses.
Cultivation and Care
Growing Conditions
Nasturtiums thrive in moderate climates and prefer well-drained soil with moderate fertility. They can tolerate various soil types but perform best in slightly sandy or loamy soil. Choose a sunny location for optimal flowering, though they can tolerate partial shade.
Planting
- Seeds: Nasturtium seeds are large and easy to handle, making them ideal for direct sowing. Plant seeds directly into the soil after the last frost date, spacing them about 10-12 inches apart.
- Transplanting: Alternatively, you can start seeds indoors 4-6 weeks before the last frost and transplant them outdoors once the weather warms up.
Care
- Watering: Keep the soil consistently moist but not waterlogged. Water deeply when the top inch of soil feels dry.
- Fertilization: Nasturtiums are light feeders. A balanced fertilizer applied once a month during the growing season is usually sufficient.
- Pest and Disease Control: Nasturtiums are generally pest-resistant but can occasionally attract aphids. Companion planting with marigolds or herbs like basil can help deter pests naturally.
