When to Plant Nasturtium Seeds: A Guide to Timing Your Planting
Nasturtiums are beautiful and edible flowers that can add a pop of color and flavor to any garden or salad. But when is the best time to plant nasturtium seeds? This is a common question among gardeners, and the answer depends on various factors.
Firstly, it’s important to note that nasturtiums are annual plants that thrive in warm weather. Therefore, it’s best to plant them in the spring after the last frost has passed. This ensures that the seeds have enough warmth and sunlight to germinate and grow properly. Additionally, nasturtiums prefer well-draining soil and full sun exposure, so make sure to choose a suitable location for planting.
Another factor to consider is the purpose of planting nasturtiums. If the goal is to harvest the flowers for salads, it’s best to plant the seeds in early spring so that they bloom in late spring or early summer. This ensures that the flowers are at their peak flavor and appearance. However, if the goal is to use nasturtiums as a ground cover or ornamental plant, they can be planted later in the season as well. Overall, the timing of planting nasturtium seeds depends on the desired outcome and the local climate.
