When to Plant Nasturtium Seeds

Nasturtium is a popular plant that is grown for its vibrant and colorful flowers. It is an annual plant, which means that it completes its life cycle in one growing season. If you are planning to grow nasturtium plants in your garden, the first thing you need to know is when to plant their seeds. In this article, we will discuss the best time to plant nasturtium seeds.

Early Spring Planting

Nasturtium seeds can be planted outdoors in the early spring, after the last frost has passed. The ideal temperature for germination is between 65-75掳F (18-24掳C). It is important to choose a sunny spot for planting, as the plants need at least 6 hours of sun each day. The soil should be well-draining and fertile, with a pH between 6.0-7.5.

Late Spring Planting

Nasturtium seeds can also be planted in the late spring, around May or June. By this time, the soil has warmed up, making it easier for seeds to germinate. However, the planting period may vary depending on the climatic conditions in your region. It is advisable to check with your local nursery or agricultural extension service for the best planting time.

Fall Planting

In regions where the winters are mild, nasturtium seeds can be planted in the fall. The plants will bloom in the spring, providing early color to your garden. However, this method is not recommended for areas with harsh winters, as the plants may not survive.

Tips for Planting Nasturtium Seeds

Now that you know when to plant nasturtium seeds, here are some tips to ensure successful growth:

- Prepare the soil by loosening it with a garden fork or spade. If the soil is heavy or clayey, add some organic matter such as compost or aged manure to improve drainage and fertility.

- Plant the seeds about 1 inch deep and 10-12 inches apart. Cover them with soil and water gently.

- Keep the soil moist but not waterlogged. Avoid overhead watering, as it can lead to fungal diseases such as powdery mildew.

- Once the seeds have germinated, thin out the weaker seedlings, leaving only one plant per 10-12 inches. This will give them enough space to grow and prevent overcrowding.

- If you want to promote bushier growth, pinch back the tips of the plants when they are about 6 inches tall. This will encourage branching and more flowers.

- Nasturtium seeds can also be started indoors, 4-6 weeks before the last frost date. Transplant the seedlings outdoors after the last frost, when they are about 4-6 inches tall.

Conclusion

Planting nasturtium seeds is easy and rewarding, as they require little care and produce beautiful flowers. By following the tips mentioned above and choosing the right time to plant, you can enjoy a colorful display of nasturtiums in your garden. So, plan ahead and enjoy the beauty of nasturtiums in your garden!
