How to Grow Garden Nasturtium
Growing garden nasturtium is quite easy, making it an excellent choice for both novice and experienced gardeners. Here are some essential tips for cultivating this edible wonder in your garden.
Choosing the Right Location
Garden nasturtium thrives in full sun but can also tolerate partial shade. Select a spot in your garden that receives at least six hours of sunlight each day to promote healthy growth and abundant flowering.
Soil Requirements
This plant prefers well-draining soil and can grow in a variety of soil types, including sandy or loamy soil. Amending the soil with organic matter, such as compost, can enhance nutrient availability and support robust plant growth.
Sowing Seeds
You can sow seeds directly into the garden once the danger of frost has passed, usually in late spring. Space seeds about 10 to 12 inches apart, as garden nasturtium plants can spread widely.
Watering and Maintenance
Garden nasturtiums are relatively drought-tolerant once established. However, regular watering will promote healthier growth and more vibrant flowers. Keep the soil consistently moist but not soggy.
Pruning dead or wilted flowers will encourage new blooms and help maintain the plant’s aesthetic appeal while supporting continued harvest opportunities.
Pest Control
One of the advantages of growing garden nasturtium is its ability to attract beneficial insects, such as predatory wasps that help control pest populations. However, it’s always advisable to monitor for pests. If infestations occur, consider natural pest control methods, such as neem oil or insecticidal soap.
Harvesting Garden Nasturtium
Harvesting is an essential part of enjoying garden nasturtium. Here are some guidelines to ensure you get the best yield from your plants.
When to Harvest
You can begin harvesting garden nasturtium leaves once the plant has reached a height of about 6 to 8 inches. Leaves can be picked at any time, but young, tender leaves are often the most flavorful. Flowers can be harvested once they are fully open.
How to Harvest
To harvest leaves, gently pluck them from the stem. For flowers, pinch them off close to the base of the flower stem. Avoid taking more than one-third of the plant at a time to allow it to continue growing healthily.
Storing Nasturtiums
Fresh garden nasturtium can be wrapped in a damp paper towel and stored in the refrigerator for several days. If you plan to use them later, consider freezing the leaves or preparing preserves like pesto to maintain their freshness.

Can nasturtium be grown in containers?
Absolutely! Garden nasturtiums are well-suited for container gardening, making them perfect for those with limited outdoor space. They thrive in well-draining soil and appreciate a good amount of sunlight, ideally requiring around 6 hours of direct sunlight daily. By utilizing pots or balcony containers, you can grow nasturtiums in small spaces while still enjoying their beauty and culinary uses.
When growing nasturtiums in containers, make sure to water them regularly to keep the soil moist but not soggy. Fertilization is optional since nasturtiums can flourish in poorer soils, but a balanced fertilizer can sometimes enhance their growth. With appropriate care, you can create a flourishing kitchen garden right on your balcony or porch.
What is the best time to plant nasturtium?
The ideal time to plant garden nasturtiums is in the spring after the last frost has passed. Nasturtiums prefer warm weather, and temperatures above 50°F (10°C) encourage germination. Since they are fast-growing annuals, planting them in early spring allows them to establish themselves and flourish throughout the summer months.
If you are in a region with a short growing season, consider starting seeds indoors to give them a head start. Once the danger of frost is past, you can transplant the seedlings outdoors. In milder climates, nasturtiums can also flourish if sown in late summer or early fall, giving them time to establish before the cooler months arrive.
Are there any pests that affect nasturtium plants?
Nasturtiums are generally resistant to many common garden pests, but they can still occasionally face challenges. Aphids, whiteflies, and spider mites are the most common pests that may affect these plants. Attracting beneficial insects, such as ladybugs and lacewings, can naturally help control these populations, as they dine on harmful pests.
In some cases, the presence of pests can indicate an imbalance in the garden ecosystem. Regularly monitoring your nasturtiums and implementing organic pest control methods, like insecticidal soap or neem oil, can effectively manage any infestations without harming the plant. This proactive approach will help you maintain a healthy, thriving nasturtium garden.
Can nasturtium seeds be saved for future planting?
Yes, you can save nasturtium seeds for future planting, making them a sustainable choice for gardeners. Once the flowers have bloomed and faded, the pods will develop and begin to dry out. It’s essential to wait until the pods have turned brown and brittle before harvesting them, as immature seeds may not germinate or produce healthy plants.
After collecting the seeds, store them in a cool, dry place in a breathable container, such as a paper bag or envelope. Properly stored seeds can remain viable for several years, allowing you to enjoy the beauty and flavor of nasturtiums season after season. By saving seeds, you can also preserve your favorite varieties and share them with fellow gardening enthusiasts.
Are there any culinary recipes featuring nasturtium?

This dish not only tastes delicious but is visually appealing as well.
Another idea is to make nasturtium pesto by blending the leaves with nuts, cheese, garlic, and olive oil.
