What are the benefits of growing nasturtiums in my garden?
Growing nasturtiums in your garden can provide numerous benefits. One of the most significant advantages is their ability to repel pests, such as aphids, whiteflies, and cucumber beetles, which can damage other plants. Nasturtiums also attract beneficial insects, like lacewings and hoverflies, which prey on these pests. Additionally, nasturtiums have natural fungicidal properties, which can help prevent the spread of diseases like powdery mildew and leaf spot.
Nasturtiums are also a versatile and low-maintenance addition to any garden. They are easy to grow and can thrive in a variety of conditions, making them perfect for gardeners of all skill levels. Their vibrant, delicate flowers come in a range of colors, including yellow, orange, red, and cream, and can add a pop of color to any garden bed or container. Furthermore, nasturtiums can be used as a natural dye, and their leaves and flowers can be eaten raw in salads or used as a garnish, providing a peppery, spicy flavor.
How do I plant and care for nasturtiums in my garden?
To plant nasturtiums, start by selecting a location with full sun to partial shade and well-draining soil. Sow seeds directly in the ground after the last frost, or start them indoors 4-6 weeks before the last frost date. Plant seeds about 1-2 inches deep and 12-18 inches apart. Water gently but thoroughly, and keep the soil consistently moist during the first few weeks after planting. As the plants grow, provide support if necessary, and fertilize lightly to promote healthy growth.
Once established, nasturtiums are relatively drought-tolerant and require minimal care. Deadhead spent flowers to promote continuous blooming, and trim back leggy stems to encourage bushy growth. Nasturtiums can be susceptible to root rot if the soil is too moist, so avoid overwatering. Mulch around the plants to retain moisture and suppress weeds. With proper care, nasturtiums can bloom from mid-spring to early fall, providing a vibrant display of color and a bountiful harvest of edible leaves and flowers.
Can I grow nasturtiums in containers, and how do I care for them?
Yes, nasturtiums can be grown in containers, providing a versatile and space-saving way to enjoy these beautiful flowers. Choose a container with good drainage and a well-draining potting mix.

Water gently but thoroughly, and keep the soil consistently moist during the first few weeks after planting. As the plants grow, provide support if necessary, and fertilize lightly to promote healthy growth.
When growing nasturtiums in containers, make sure to provide enough sunlight and maintain consistent moisture levels. Nasturtiums in containers may require more frequent watering, as the soil can dry out quickly. Fertilize regularly, but avoid overfertilizing, which can lead to weak and leggy growth. Prune back the plants regularly to maintain shape and promote bushy growth. With proper care, nasturtiums in containers can thrive and provide a beautiful display of color and fragrance. Keep in mind that nasturtiums can trail and spread, so choose a container that is large enough to accommodate their growth.

The leaves and flowers have a peppery, spicy flavor and can be eaten raw in salads, used as a garnish, or added to sandwiches and wraps. The seed pods can be pickled or used as a caper substitute. Nasturtiums can also be used to make a natural dye, and their flowers can be used as a garnish for cocktails and other beverages.
To use nasturtiums in cooking, simply harvest the leaves and flowers as needed, and wash them thoroughly with water.

By incorporating nasturtiums into your garden, you can create a balanced ecosystem that is less reliant on chemical pesticides and more resilient to pest infestations.
Can I grow nasturtiums indoors, and what are the requirements for indoor growth?
Yes, nasturtiums can be grown indoors, providing a beautiful and fragrant addition to any room. To grow nasturtiums indoors, you will need to provide them with sufficient light, preferably in a south-facing window or under grow lights. The temperature should be kept between 65-75°F (18-24°C), and the soil should be kept consistently moist. Fertilize lightly, as nasturtiums can be sensitive to overfertilization.
When growing nasturtiums indoors, make sure to choose a container that is large enough to accommodate the mature size of the plant. Nasturtiums can trail and spread, so provide a trellis or other support for the stems to climb.
