The Growers Guide to Nasturtium

Growing Nasturtium: The Grower's Guide

Ah, nasturtium. This vibrant, sprawling beauty is a joy in the garden. I remember the first time I planted nasturtium seeds; I didn’t expect much. However, their unfussy nature quickly proved they were more than just pretty petals.

Why Choose Nasturtium?

These flowers aren’t just decorative; they’re practical, too. Nasturtiums are known for their peppery taste, making them a delightful addition to salads. Their bright blooms attract pollinators, and they serve as a natural pest repellent.

"Nasturtium leaves and flowers are entirely edible, earning them a spot in both the garden and the kitchen."

Optimal Growing Conditions

Soil and Sunlight

Nasturtium thrives in poor soil. Yes, you heard that right! In rich soil, they tend to produce more leaves than flowers. All they ask for is good drainage and plenty of sunlight. Aim for at least six hours of direct sun daily.

Watering Needs

While they’re drought-tolerant, nasturtiums appreciate consistent moisture. Avoid waterlogging, though — they dislike standing in soggy soil. I found a weekly watering schedule sufficient for a thriving display.

Planting Nasturtium

Direct sowing is the way to go with these seeds. In my experience, soaking the seeds overnight helps with germination. It softens their tough outer shell, making it easier for sprouts to break through.

1. Wait until after the last frost date.
2. Sow seeds about half an inch deep and 10-12 inches apart.
3. Water gently and keep the soil moist until germination.

Companion Planting and Pests

Nasturtiums work wonders as companion plants. They pair beautifully with tomatoes, cucumbers, and radishes. Their pungent scent deters pests like aphids and whiteflies, keeping your vegetable patch healthier.

However, they can attract caterpillars. This isn’t always bad, as it diverts these hungry creatures away from other plants. I’ve found them a handy trap crop in this regard.

Harvesting and Using Nasturtium

Regularly harvesting leaves and flowers encourages new growth. I love sprinkling the vibrant blooms over a fresh summer salad. The seeds can even be pickled to create 'poor man's capers'.

To harvest seeds for next season, simply wait for the blooms to fade. Pods will form, bursting with seeds that are easy to collect once they’ve dried on the plant.

Final Thoughts

Growing nasturtium is an easy, rewarding endeavor. Their carefree nature makes them perfect for beginner gardeners. And yet, their versatility and beauty ensure they remain a favorite of seasoned growers, too.

Growing Nasturtium is an excellent way to add a bright, vibrant splash of color to any garden. Not only are they a beautiful addition, but they attract beneficial insects that ward off bad pests and are naturally disease-resistant. The edible flowers, leaves and seed pods provide an incredible array of culinary and medicinal uses, making them an incredibly rewarding plant to grow!
