Planting Nasturtiums in Containers: A Comprehensive Guide

Introduction to Planting Nasturtiums in Containers

Planting nasturtiums in containers is an excellent choice for gardeners of all experience levels. These versatile plants add a vibrant splash of color and a special peppery flavor to dishes, making them a delightful addition to any garden. This guide will walk you through the process from planting to care, ensuring you can successfully grow nasturtiums in containers.

What You Will Need

Materials Needed:

Container: Choose a pot that is at least 6-12 inches deep with drainage holes. Potting Mix: Use a well-draining potting soil. Nasturtium Seeds: Seeds or seedlings can be used, but seeds are more common for container gardening.

Steps for Planting Nasturtiums in Containers

Step 1: Choose the Right Time

To ensure successful germination and growth, sow nasturtium seeds after the last frost if planting directly in the container. Alternatively, start them indoors about a month before the last expected frost in your area, then move them outside after they have a few sets of leaves. For peat pots, simply start the seeds indoors and transfer them directly into the larger containers without disturbing the roots.

Step 2: Prepare the Container

Fill the container with well-draining potting mix, leaving about an inch of space at the top. Ensure the soil is loose and well-aerated to promote healthy roots. If using seedlings, plant them at the same depth they were growing in their original container. For seeds, plant them about 1 inch deep and 4-6 inches apart.

Step 3: Watering and Germination

Water the soil gently after planting to settle it around the seeds or seedlings. Keep the soil consistently moist but not soggy, especially during germination. Germination typically occurs within 7-14 days.

Step 4: Light Requirements

Place the container in a location that receives full sun, ensuring at least 6 hours of direct sunlight daily. Proper lighting is crucial for healthy growth and abundant flowering.

Care and Maintenance

Watering

Once the plants are established, water regularly, especially during dry spells. Nasturtiums are drought-tolerant but may wilt if the soil becomes too dry. A good rule of thumb is to water when the top 2 inches of soil feels dry. In hot weather, they may need daily watering.

Fertilizing

While not necessary, you can feed your nasturtiums with a very dilute solution of a general-purpose, water-soluble fertilizer if the growth appears weak. Avoid overfertilizing as it can produce excessive foliage and reduce blooming.

Pruning and Pinching

Pinch back the tips of the plants if they become leggy to encourage bushier growth. Thin the tiny plants if they appear too crowded, allowing one healthy plant in a small pot and two or three in a larger pot.

Harvesting Nasturtiums

Both the leaves and flowers of nasturtiums are edible and add a tangy peppery flavor to salads and other dishes. Harvest them once the plants are established to promote continued growth.

Additional Tips

Nasturtiums thrive in slightly drier conditions, so be cautious about overwatering. Peat pots can be used to eliminate the problem of transplanting by planting them directly into the larger container. Soaking seeds overnight can speed up germination and improve growth.

Conclusion

Planting and caring for nasturtiums in containers is a straightforward and rewarding experience. Whether you are a seasoned gardener or new to gardening, these comprehensive steps will ensure your nasturtiums thrive. Enjoy their vibrant colors and unique flavors in your kitchen and garden.
