Flame nasturtiums are stunning flowering plants that can bring a burst of color to any garden or balcony. These vibrant flowers come in shades of fiery red, orange, and yellow, making them a popular choice for gardeners looking to add a pop of color to their outdoor spaces. Growing flame nasturtiums in pots is a great way to enjoy these beautiful blooms in a compact setting. In this guide, we will walk you through everything you need to know to successfully grow flame nasturtium plants in a pot.

Choosing the Right Pot

When it comes to growing flame nasturtiums in pots, choosing the right container is crucial. Opt for a pot that is at least 12 inches in diameter and has drainage holes at the bottom. This will ensure that excess water can easily escape, preventing root rot and other water-related issues.

Additionally, consider using a pot with a trellis or support system if you plan to grow climbing varieties of flame nasturtiums. This will provide the necessary support for the vines to climb and flourish.

Selecting the Right Soil

Flame nasturtiums thrive in well-draining soil that is rich in organic matter. A good potting mix for these plants should be light and airy, allowing for proper root growth and drainage. You can use a commercial potting mix designed for flowering plants or create your own by mixing equal parts of peat moss, perlite, and compost.

Planting Flame Nasturtium Seeds

Flame nasturtium seeds are easy to plant and germinate, making them an excellent choice for beginner gardeners. To plant flame nasturtium seeds in a pot, follow these simple steps:

  1. Fill your pot with potting mix, leaving about an inch of space at the top.
  2. Moisten the soil lightly before planting the seeds.
  3. Plant the seeds about 1 inch deep and 2-3 inches apart.
  4. Gently cover the seeds with soil and water thoroughly.
  5. Place the pot in a sunny location where it will receive at least 6-8 hours of sunlight per day.

Watering and Care

Flame nasturtiums are relatively low-maintenance plants that require minimal care once established. Here are some tips for watering and caring for your flame nasturtium plants:

  • Watering: Water your flame nasturtiums regularly, keeping the soil evenly moist but not waterlogged. Allow the top inch of soil to dry out between waterings to prevent overwatering.

  • Fertilizing: Feed your flame nasturtium plants with a balanced liquid fertilizer every 2-3 weeks during the growing season. This will help promote healthy growth and abundant flowering.

  • Pruning: Deadhead spent flowers regularly to encourage continuous blooming and prevent the plant from going to seed prematurely.

  • Pest Control: Keep an eye out for common pests such as aphids and caterpillars, which can damage flame nasturtium plants. Use organic pest control methods or insecticidal soap to manage pest infestations.

Harvesting Seeds

Flame nasturtium plants produce edible seeds that have a peppery flavor and can be used in salads, pesto, or as a garnish. To harvest nasturtium seeds:

  1. Allow the flowers to fade and dry on the plant.
  2. Once the seed pods are dry and crisp, carefully remove them from the plant.
  3. Crack open the seed pods to collect the seeds.
  4. Store the seeds in a cool, dry place until ready to use.
