How to Plant Nasturtium


Nasturtiums are edible flowers that also make a good companion plant for radishes, cabbages, broccoli and mustard plants. They help deter pests such as squash bugs, cucumber beetles and aphids. Nasturtiums are both healthy and attractive plants to grow in the garden; they are grown from large seeds, which makes planting simple.

Difficulty: Moderately Easy


  1. Choose a location with light sandy soil that has access to full sun or partial shade. These plants are hardy and do well in a variety of locations.

  2. Plant after the last frost date in the area. A cold frost while nasturtiums are germinating can kill them, so wait until the weather has warmed up for the season.

  3. Plant each large nasturtium seed by hand; dig holes about 1 inch deep and 8 to 12 inches apart. This ensures each plant enough resources to feed on as it grows. Nasturtiums germinate within 10 days of putting the seed in the soil.

  4. Water when the soil around the base of the nasturtium feels slightly dry to the touch. This plant does not thrive when it is too dry.

Tips & Warnings

  • Nasturtiums are versatile plants that can be grown in a number of different locations, including window boxes, flower beds, containers, and hanging baskets.

  • Avoid using excessive fertilizers on nasturtiums as you will get more foliage than flowers. Use a soluble liquid fertilizer that has been diluted with water to one-half to one-quarter strength every three weeks.
