Nasturtiums, with their cheerful blooms and easy-growing nature, are a favorite among gardeners. But beyond their beauty, these remarkable plants offer numerous benefits, from repelling pests to being edible delights. Whether you’re a beginner gardener or a seasoned pro, nasturtiums are a must-have for any garden. In this article, we’ll delve deep into the world of nasturtiums—how to grow them, care for them, and reap their many benefits.
What Are Nasturtiums?
Nasturtiums (genus Tropaeolum) are flowering plants that come in vibrant shades of yellow, orange, and red. Native to South and Central America, these plants are not only beautiful but also versatile. They grow well in gardens, containers, and even hanging baskets. Known for their edible flowers, leaves, and seeds, nasturtiums bring both aesthetic and culinary value to your garden.
Why Choose Nasturtiums for Your Garden?
- Stunning Appearance:
Their bright, trumpet-shaped flowers and trailing vines add a burst of color to any space. - Low Maintenance:
Nasturtiums are hardy plants that thrive with minimal effort, making them perfect for busy gardeners or those new to gardening. - Natural Pest Repellent:
They repel pests like aphids, whiteflies, and squash bugs, protecting your vegetable garden naturally. - Attract Pollinators:
Bees, butterflies, and hummingbirds love nasturtiums, ensuring better pollination for your crops. - Edible and Delicious:
The flowers, leaves, and seeds have a peppery flavor, perfect for salads, garnishes, or pickling. - Soil Improvement:
Nasturtiums can grow in poor soil, preventing erosion and enhancing its overall health.
How to Grow Nasturtiums
Step 1: Selecting the Right Spot
Nasturtiums prefer full sun but can tolerate partial shade. Choose a location with well-draining soil. They thrive in poor soil conditions, making them perfect for areas where other plants may struggle.
Step 2: Planting Nasturtium Seeds
- Sow nasturtium seeds directly in the garden after the last frost date.
- If starting indoors, plant seeds in biodegradable pots 2-4 weeks before the last frost.
- Space seeds about 10–12 inches apart to allow the plants room to spread and grow.
Step 3: Watering
Water regularly, especially during dry spells, but avoid overwatering. Nasturtiums prefer slightly dry soil. Overwatering can lead to root rot and hinder flowering.
Step 4: No Fertilizer Needed
Nasturtiums thrive in nutrient-poor soil. Adding fertilizer can cause lush foliage but fewer blooms.
Step 5: Pest Control
Use nasturtiums as companion plants near vegetables like tomatoes, cucumbers, and squash. They act as a trap crop, attracting pests away from your main plants.
Step 6: Supporting Trailing Varieties
For vining nasturtiums, provide a trellis or support to allow them to climb. This not only saves space but also showcases their vibrant blooms.
Step 7: Deadheading and Maintenance
Remove spent flowers regularly to encourage continuous blooming. If the plants start to look scraggly, trim back the vines to promote bushier growth.
Creative Uses for Nasturtiums
In the Kitchen
- Edible Flowers: Add nasturtium flowers to salads for a splash of color and a peppery flavor.
- Leaves: Use young leaves as a substitute for arugula or spinach.
- Seeds: Pickle immature seeds as a caper alternative.
As Natural Pest Control
Plant nasturtiums near cabbage, broccoli, and kale to deter pests like cabbage worms.
