Optimal Planting Time
The best time to plant nasturtium is in late spring, once the danger of frost has passed. In warmer regions, you can start them in early spring, while in cooler areas, late spring is ideal.
How to Plant Nasturtium in Your Vegetable Garden
Planting nasturtium requires a few simple steps that will help you achieve vigorous growth.
Materials Needed
Before planting, gather the following materials:
- Nasturtium seeds or seedlings
- Garden trowel
- Compost or well-rotted manure

If using seedlings, dig a hole large enough to accommodate the root ball.
Water Thoroughly: After planting, water the area gently but thoroughly. Keep the soil moist, particularly during dry spells.
Thinning: If you find that you have planted too close together, thin the seedlings once they reach about 2 inches tall.
Caring for Your Nasturtium Plants
Once planted, proper care will ensure your nasturtiums flourish.
Watering
Nasturtiums require moderate watering. Once established, they can tolerate short periods of drought. However, if the weather is exceptionally dry, you may want to provide additional water to keep the plants healthy.
Fertilization
Since nasturtiums thrive on undernourished soil, only apply a light layer of compost if required. Avoid high-nitrogen fertilizers, which can produce lush leaves at the expense of blooms.
Pest Management
Although nasturtiums deter some pests, they may occasionally attract aphids. If this happens, consider using a gentle organic insecticidal soap or simply wash them off with a strong stream of water.
Harvesting
Nasturtiums can be harvested continuously throughout the growing season. Choose the leaves and flowers before they fully mature for the best flavor.

What is Nasturtium and why should I plant it in my vegetable garden?
Nasturtium is a vibrant flowering plant known for its edible leaves and flowers, which can add both beauty and flavor to your vegetable garden. The plant belongs to the Tropaeolum family and features bright oranges, yellows, and reds that attract pollinators, making it a beneficial companion plant for your veggies. It can also help repel pests such as aphids and beetles, thereby enhancing the overall health of your garden.
In addition to their aesthetic appeal, nasturtiums have a peppery flavor, similar to arugula, which makes them a unique addition to salads and other dishes. You can use the flowers as a colorful garnish, and the leaves in salads for a zesty kick. With a variety of culinary uses and beautiful blooms, nasturtiums serve multiple purposes in the garden.
How do I plant nasturtium seeds?
Planting nasturtium seeds is quite straightforward. Select a sunny location in your vegetable garden with well-draining soil for optimal growth. Prepare the soil by loosening it and mixing in some organic compost to improve fertility. You should plant the seeds about one inch deep and a few inches apart, ensuring they have enough space to spread as they grow.
The best time to sow nasturtium seeds is in the spring after the last frost or in the fall for a late-season crop. Water the seeds gently after planting and keep the soil consistently moist until the seeds germinate, which usually takes about one to two weeks. Once the seedlings emerge, you can thin them out if they appear too crowded to promote better growth.
What are the best growing conditions for nasturtiums?
Nasturtiums thrive in full sun and well-drained soil, making them perfect for vegetable gardens. Ideally, they prefer a soil pH of 6.0 to 7.0 but can tolerate a range of soil types. They are hardy plants that can adapt, yet providing them with fertile, slightly sandy soil will stimulate stronger growth and more abundant blooms.
While they need plenty of sunlight, nasturtiums can also tolerate partial shade. However, too much shade may lead to leggy growth and fewer flowers. Additionally, these plants prefer moderate watering; overwatering can lead to root rot, while underwatering may hinder their growth. Keeping an eye on their moisture levels is essential for optimal health.
Can I grow nasturtiums indoors?
Yes, you can grow nasturtiums indoors, but they typically perform best when they have ample sunlight and space. To grow them indoors, choose a well-lit window that receives at least six hours of sunlight each day. Alternatively, you can use grow lights if natural light is insufficient.
Plant nasturtium seeds in pots with good drainage and a well-balanced potting mix. Regular watering is important, but be careful not to let the soil become waterlogged. Watch for pests such as aphids and spider mites, which may be more prevalent indoors, and address any infestations promptly to keep your plants healthy.
How do I care for nasturtiums as they grow?
Caring for nasturtiums is relatively easy. Once planted, make sure to weed the area regularly to reduce competition for nutrients and water. Applying a light layer of mulch can help retain moisture and control weeds. Monitor your plants for any signs of pest infestations, and take appropriate measures if you notice aphids or caterpillars.
Water your nasturtiums consistently, without overwatering, to ensure robust growth and vibrant blooms. As they mature, you might want to pinch back the tips of the plants to encourage bushier growth and more flowers. Fertilizing is not usually necessary, as too much nitrogen can lead to lush foliage with fewer blooms.
Are nasturtium flowers and leaves really edible?
Yes, both nasturtium flowers and leaves are edible and safe to consume. The leaves have a peppery flavor, great for adding a spicy touch to salads, sandwiches, and other culinary creations. The flowers, which are equally edible, add a splash of color to your dishes and can be used as beautiful garnishes or in salads to provide a unique flavor.
When harvesting, make sure to choose healthy, pesticide-free plants. It’s best to use them fresh, but you can also preserve the flowers in vinegar or use them in other recipes. Avoid harvesting them when they are wet, as this can affect their freshness and flavor.
What pests or diseases should I watch for with nasturtiums?
Nasturtiums are generally resilient plants, but they can be susceptible to certain pests and diseases. Common pests include aphids, which can cluster on the undersides of leaves, and spider mites, which thrive in dry conditions. If you see any signs of infestation, consider treating the plants with insecticidal soap or introducing beneficial insects like ladybugs to help manage the populations naturally.
In terms of diseases, nasturtiums are prone to fungal issues like powdery mildew, especially in humid conditions. To reduce the chances of this occurring, ensure good air circulation around the plants by spacing them properly and avoid overhead watering. If you do notice powdery mildew, you can remove affected leaves and apply a fungicide if necessary.
When is the best time to harvest nasturtiums?
The best time to harvest nasturtiums is in the morning after the dew has dried but before the heat of the day sets in. This timing helps preserve their flavor and texture. You can begin harvesting leaves and flowers once the plants are well-established, typically about 6-8 weeks after planting.
To encourage continued growth and production, only harvest a portion of the foliage and flowers at a time, leaving enough on the plant so it can keep thriving throughout the growing season. Regular harvesting will promote more blooms and fresh leaves, allowing you to enjoy the beauty and flavor of nasturtiums for an extended period.
