Nasturtiums are beautiful and versatile plants that are perfect for growing in pots. Their vibrant flowers and edible leaves make them a popular choice for gardeners looking to add color and flavor to their outdoor spaces. In this guide, we will explore everything you need to know about growing nasturtium plants in pots.
Choosing the Right Pot
When selecting a pot for your nasturtium plant, it is important to choose one that is the right size and material. Nasturtiums have long roots, so opt for a pot that is at least 12 inches deep to allow for proper root growth. Additionally, make sure the pot has drainage holes to prevent waterlogging, which can lead to root rot.
Terracotta or ceramic pots are ideal choices for growing nasturtiums as they provide good drainage and help regulate soil moisture levels. Plastic pots can also be used, but ensure they have adequate drainage holes at the bottom.
Selecting the Right Soil
Nasturtiums thrive in well-draining soil that is rich in organic matter. A good potting mix designed for flowering plants or vegetables will work well for nasturtiums. You can also create your own mix by combining equal parts of potting soil, compost, and perlite or sand to improve drainage.
Avoid using heavy clay soils or dense garden soil, as these can retain too much moisture and lead to root rot. Ensure the soil is loose and airy to promote healthy root development.
Planting Nasturtium Seeds or Seedlings
Nasturtiums can be grown from seeds or seedlings, depending on your preference. If starting from seeds, sow them directly into the pot after the last frost date in your area. Plant the seeds 1 inch deep and space them 6-8 inches apart to allow room for growth.
If using seedlings, carefully transplant them into the pot, making sure not to disturb the roots. Gently firm the soil around the seedling and water thoroughly to help it establish in its new environment.
Sunlight and Watering Needs
Nasturtiums thrive in full sun and require at least 6-8 hours of sunlight per day to grow and flower abundantly. Place your pot in a sunny location, such as a south-facing patio or balcony where it can receive ample sunlight.
Water your nasturtium plant regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out between waterings to prevent overwatering.
Fertilizing and Maintenance
Nasturtiums are relatively low-maintenance plants that do not require frequent fertilization. However, you can feed your plant with a balanced liquid fertilizer once a month during the growing season to promote healthy growth and flowering.
Deadhead spent flowers regularly to encourage continuous blooming and prevent the plant from going to seed prematurely. Remove any yellowing or damaged leaves to keep the plant looking tidy and healthy.
Pests and Diseases
Nasturtiums are generally resistant to pests and diseases, making them an easy plant for beginner gardeners. However, aphids and caterpillars may occasionally feed on the leaves of nasturtium plants.
To control pests, spray the plant with a mixture of water and insecticidal soap or neem oil. Alternatively, you can introduce beneficial insects like ladybugs or lacewings to help keep pest populations in check.
Harvesting Nasturtium Flowers and Leaves
One of the unique features of nasturtium plants is that both their flowers and leaves are edible. The flowers have a peppery flavor, while the leaves add a spicy kick to salads and other dishes.
Harvest nasturtium flowers early in the morning when they are at their freshest and most flavorful. Simply pluck the flowers from the plant and rinse them gently before using them in culinary preparations.
For harvesting leaves, pick them when they are young and tender for the best flavor. You can use nasturtium leaves in salads, wraps, or as a garnish for savory dishes.
Conclusion
Growing nasturtium plants in pots is a rewarding experience that allows you to enjoy their colorful blooms and tasty leaves in a compact space. By following this guide on choosing the right pot, soil, sunlight exposure, watering schedule, fertilizing routine, and pest management strategies, you can successfully cultivate healthy and vibrant nasturtium plants in your own outdoor container garden.
