Growing Guide: Nasturtiums (Tropaeolum spp.)

 

Nasturtiums, those delightful trailing beauties, are not just a treat for the eyes but also a feast for the palate! With their vibrant blooms and peppery leaves, they add a splash of color and flavor to any garden. Whether you're a seasoned gardener or just starting out, growing nasturtiums (Tropaeolum spp.) is a breeze. Let's dive into this growing guide and unlock the secrets to cultivating these cheerful plants.

Getting to Know Nasturtiums

Before we get our hands dirty, let's acquaint ourselves with our star plant. Nasturtiums belong to the genus Tropaeolum and come in various species and cultivars. They're known for their round, shield-shaped leaves and brilliantly colored flowers that range from fiery oranges and yellows to soft creams and reds. Edible from leaf to petal, nasturtiums offer both ornamental and culinary appeal.

Planting Nasturtiums

Nasturtiums are champions of versatility and adaptability, thriving in various conditions. Here's how to get started:

Soil:

Nasturtiums aren't too picky about soil quality, but they do prefer well-drained, slightly fertile soil. However, they can tolerate poorer soils as well, making them excellent candidates for less-than-ideal garden spots.

Sunlight:

These sun-worshippers thrive in full sun but can tolerate partial shade. Aim for at least 6 hours of sunlight daily for optimal growth and blooming.

Planting:

When the threat of frost has passed and the soil has warmed up, sow nasturtium seeds directly into the ground. Space seeds about 10 to 12 inches apart and cover them lightly with soil. You can also start seeds indoors a few weeks before the last frost date and transplant them outside once the weather warms up.

Care and Maintenance

Once your nasturtiums are settled in, they require minimal care but reward you with abundant blooms. Here are some tips to keep them thriving:

Watering:

Nasturtiums are drought-tolerant once established but appreciate regular watering, especially during dry spells. Water them deeply when the soil feels dry to the touch.

Fertilizing:

Avoid overly rich soil or excessive fertilization, as this can result in lush foliage but fewer flowers. A balanced, all-purpose fertilizer applied sparingly in early spring is usually sufficient.

Pruning:

While not strictly necessary, deadheading spent blooms can encourage continuous flowering and keep the plants looking tidy. Plus, you can munch on the peppery petals as you go!

Pests and Problems

Nasturtiums are relatively pest and disease-resistant, but they can occasionally encounter some issues:

Aphids:

These tiny pests sometimes take a liking to nasturtiums. Blast them off with a strong jet of water or introduce beneficial insects like ladybugs to keep them in check.

Powdery Mildew:

In humid conditions, nasturtiums can fall prey to powdery mildew. Improve air circulation around the plants and avoid overhead watering to prevent this fungal disease.

Harvesting and Enjoying

The best part of growing nasturtiums? The harvest, of course! Here's how to make the most of your bounty:

Leaves:

Add a peppery punch to salads, sandwiches, and stir-fries by tossing in nasturtium leaves. They make a zesty addition to any dish.

Flowers:

Nasturtium flowers aren't just for show—they're a culinary delight! Use them to garnish salads, desserts, and appetizers for a pop of color and flavor.

Seeds:

Did you know nasturtium seeds are edible too? Pick them when they're still green and tender, then pickle them for a unique and tasty treat.

In Summary

Nasturtiums are the perfect addition to any garden, offering beauty, flavor, and versatility in one vibrant package. Whether cascading from a hanging basket or spilling over a garden bed, these cheerful plants are sure to brighten up your outdoor space. So go ahead, sow some seeds, and let nature's fireworks begin!
