Are you looking to add a touch of vibrant color and unique charm to your garden while also supporting our buzzing and fluttering friends? Nasturtiums might just be the perfect choice for you! These delightful flowers are not only a feast for the eyes but are also edible, making them a versatile addition to your culinary adventures and gardening endeavors. Let’s journey through the steps to successfully grow edible nasturtiums in containers.
What Makes Nasturtiums Special?
Nasturtiums (Tropaeolum spp.) are known for their bright, funnel-shaped flowers that range from warm yellows to deep reds. Their peppery-tasting leaves and flowers are edible and can be used to spice up salads, pastas, and even sandwiches. Beyond their culinary use, nasturtiums play a valuable role in attracting pollinators such as bees and butterflies, making them a fantastic choice for environmentally conscious gardeners.
Edible and Beautiful
Nasturtiums are one of those rare plants that offer both visual appeal and culinary utility. Their flowers and leaves have a distinct, spicy flavor reminiscent of watercress, ideal for adding a kick to your dishes. Plus, they’re incredibly straightforward to grow in containers, making them accessible to garden enthusiasts of all skill levels.
Pollinator Magnet
If you’re aiming to create a garden haven for pollinators, nasturtiums should undoubtedly be on your list. They are excellent at attracting various pollinators, including bees and butterflies, thanks to their vibrant colors and ample nectar. This not only enhances biodiversity but also supports the health of local ecosystems.
Selecting the Right Container
Growing nasturtiums in containers is a fantastic option, especially if you’re working with limited space. The choice of pot can impact the plant’s growth and health, so it’s important to choose wisely.
Ideal Container Size
Nasturtiums thrive in containers that are at least 12 to 14 inches in diameter. The container should have good drainage to prevent waterlogging, which can lead to root rot. Ensure that the container is deep enough to allow the plant’s root system to develop fully.
Material Matters
While terracotta pots are popular for their breathability, they can dry out quickly. Plastic or glazed ceramic pots might retain moisture better, which can be beneficial in hotter climates. Choose a container material that suits your climate and aesthetic preferences, ensuring it meets the drainage requirements.

Preparing the Soil
The right soil is crucial for the healthy growth of nasturtiums. These plants aren’t too demanding but do benefit from a well-draining soil mix.
Soil Composition
A mix of regular potting soil with added coarse sand or perlite provides the perfect environment for nasturtiums. This combination ensures proper drainage and prevents the soil from becoming compacted. Avoid excessively rich soils, as they can lead to lush foliage at the expense of flowers.
Fertility Needs
Interestingly, nasturtiums thrive on neglect when it comes to feeding. High fertility can reduce flowering, so moderate fertilization is key. Incorporating a slow-release, balanced fertilizer at the time of planting is generally sufficient to meet their nutritional needs throughout the growing season.
Planting Nasturtiums
Once you’ve got your container and soil ready, it’s time to plant your nasturtiums. You can start them from seeds, which is generally the most economical and straightforward method.
Choosing Nasturtium Varieties
Nasturtiums come in a variety of forms, including bush or trailing types. Trailing varieties are ideal for container hanging baskets or over the edge of a large pot, while bush types work well in standard containers. Consider your space and design preferences when selecting which type to grow.
Planting The Seeds
Plant nasturtium seeds about 1/2 inch deep in the soil. They enjoy warmth, so planting them outside after the last frost date in your area is recommended. Seeds typically germinate within 10 to 14 days. Keep them evenly watered during this period, but avoid over-watering.

Caring for Your Nasturtiums
Once your nasturtiums begin to grow, they’re relatively low-maintenance. However, a little care goes a long way in ensuring they thrive and continue to attract pollinators.
Watering Guidelines
Nasturtiums prefer regular watering but are somewhat drought-tolerant once established. It’s crucial to let the soil dry out slightly between waterings to prevent root rot. During particularly hot and dry periods, a bit more attention to watering can help keep them looking their best.
Monitoring for Pests
While nasturtiums are quite hardy, they can be susceptible to pests like aphids. Regularly check under leaves and along stems, and use a gentle insecticidal soap if needed. Encouraging beneficial insects like ladybugs can also naturally help manage pest populations.
Blooming and Harvesting
With proper care, nasturtiums will provide a delightful display of blooms throughout the growing season. Harvesting both flowers and leaves regularly can encourage further growth.
Encouraging Blooms
Deadheading spent flowers can help prolong the blooming season, although nasturtiums will continue to flower with or without it. If you notice the plants aren’t blooming as much, check for excessive nitrogen in the soil, which may encourage leafy growth at the expense of flowers.
Harvesting for Culinary Uses
The best time to harvest nasturtium leaves and flowers is in the cooler morning hours when they are most turgid and flavorful. Clip them with clean scissors, and rinse well before use. Both can be used fresh in salads, sandwiches, or as garnishes, adding both color and a peppery taste.

Enhancing Biodiversity
Growing nasturtiums can increase the diversity of your garden and surrounding environment. They contribute to a balanced ecosystem by drawing in a variety of insects which, in turn, support birds and other wildlife.
Conclusion
Nasturtiums offer a unique blend of beauty, utility, and ecological benefit, making them an excellent choice for container gardening. Not only do they provide vibrant color and an edible touch to your dishes, but they also attract and sustain vital pollinators.
