Whether you’re a seasoned gardener or just starting out, nasturtiums offer a unique opportunity to incorporate color and flavor into your garden and kitchen. In this article, we will explore everything you need to know about growing and using nasturtiums, from planting and care to delicious recipes and health benefits.
Introduction to Nasturtiums
Nasturtiums (Tropaeolum majus) are hardy annual plants native to South America, particularly Peru and Chile. They are celebrated for their vibrant, trumpet-shaped flowers that come in various colors, including orange, yellow, and red. The plant’s leaves are round and slightly waxy, and both the flowers and leaves are edible, adding a distinctive flavor to dishes. Beyond their culinary uses, nasturtiums are also known for attracting beneficial insects, making them a great addition to any garden.
Why Grow Nasturtiums?
- Aesthetics: With their bright colors and unique shapes, nasturtiums can enhance the visual appeal of your garden.
- Culinary Use: Both the leaves and flowers have a peppery taste, similar to arugula, and can be used in a variety of dishes.
- Companion Planting: Nasturtiums can help deter pests in the garden. Their strong scent can repel aphids and whiteflies, making them great companions for vegetables.
- Health Benefits: Rich in vitamins A, C, and K, nasturtiums can boost your immune system and support overall health.
Growing Nasturtiums: A Step-by-Step Guide
1. Selecting the Right Varieties
There are two main types of nasturtiums: bush varieties and climbing varieties. Bush nasturtiums tend to grow compactly and are ideal for borders or containers, while climbing varieties can spread and may need support to grow vertically. Choose the variety that best fits your garden space and aesthetic preferences.
2. Choosing the Right Location
Nasturtiums thrive in well-draining soil and prefer full sun to partial shade. Aim for at least six hours of sunlight per day for optimal growth. If you’re planting in containers, choose pots with drainage holes to prevent waterlogging.
3. Soil Preparation
Nasturtiums prefer poor to moderately fertile soil. Avoid overly rich soils, as too much nitrogen can lead to lush foliage at the expense of flowers. Work in some organic matter, such as compost or well-rotted manure, to improve soil structure and drainage without adding too many nutrients.
4. Planting Seeds
You can start nasturtium seeds indoors 4-6 weeks before the last frost or sow them directly outdoors after the last frost date. If planting directly, space seeds about 10-12 inches apart, as they can spread widely. Plant seeds about half an inch deep in the soil, and water them gently.
5. Watering
Nasturtiums prefer slightly dry conditions and are somewhat drought-tolerant once established. Water them thoroughly but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot and other issues, so be cautious.
6. Fertilization
Because nasturtiums thrive in poor soil, fertilization should be minimal. If you must fertilize, use a balanced, low-nitrogen fertilizer once or twice during the growing season. This will encourage flowering without promoting excessive foliage growth.
7. Pruning and Maintenance
Regularly deadhead spent flowers to encourage continuous blooming. If you notice any pests, such as aphids, remove them by hand or wash them off with a strong stream of water. Keep an eye on the plants and trim any dead or damaged leaves to promote healthy growth.
8. Harvesting
You can start harvesting nasturtiums as soon as the flowers and leaves are big enough to use. Pick leaves and flowers in the morning when their flavor is at its peak. Rinse them gently under cool water and dry them on a paper towel before use. You can store fresh nasturtiums in the refrigerator for a few days.
Culinary Uses of Nasturtiums
Nasturtiums are incredibly versatile in the kitchen. Their peppery flavor adds a delightful kick to salads, sandwiches, and various dishes. Here are some creative ways to use nasturtiums:
1. Fresh Salads
Add nasturtium leaves and flowers to salads for a burst of color and flavor. Combine them with mixed greens, tomatoes, and cucumbers for a refreshing summer salad. Their peppery taste complements creamy dressings beautifully.
2. Sandwiches and Wraps
Use whole leaves as a garnish or spread them on sandwiches and wraps. They add an intriguing flavor that pairs well with meats, cheeses, and spreads.
3. Garnishes
Nasturtium flowers make stunning garnishes for soups, appetizers, and main dishes. Their vibrant colors elevate the presentation of any plate.
4. Vinegar Infusion
Create a unique salad dressing by infusing vinegar with nasturtium flowers. Place clean, dry flowers in a jar, cover with vinegar, and let it sit for a week. Strain out the flowers before using the vinegar in dressings or marinades.
5. Pesto
Blend nasturtium leaves with nuts, cheese, garlic, and olive oil to create a flavorful twist on traditional pesto. Use it as a spread, dip, or pasta sauce.
Health Benefits of Nasturtiums
Nasturtiums are not only delicious but also packed with nutrients. They contain:
- Vitamin C: Essential for immune function and skin health.
- Vitamin A: Important for vision and skin health.
- Antioxidants: Help protect the body from oxidative stress.
- Minerals: Such as iron and calcium, which support various bodily functions.
Incorporating nasturtiums into your diet can boost your overall health and provide a natural way to enjoy their benefits.
Common Issues and Solutions
While nasturtiums are generally easy to grow, they can face some common challenges:
1. Pests
Aphids and whiteflies may be attracted to nasturtiums. If you notice infestations, wash the plants with water or use insecticidal soap to control the problem.
2. Powdery Mildew
In humid conditions, nasturtiums can develop powdery mildew. Improve air circulation around the plants and avoid overhead watering to prevent this fungal issue.
3. Poor Growth
If your nasturtiums are not growing well, check the soil drainage and make sure they are not over-fertilized. Adjust watering practices as needed.
