How to Grow Nasturtiums
Not only are nasturtiums versatile and colorful, but they also are easy to grow and thrive on neglect. The large seeds germinate within a week and begin to flower about a month later, making them great choices for children or beginning gardeners. Sow in the garden about a week before the last frost date for your area. They can also be started indoors, but their taproots make them difficult to transplant. If you do grow them indoors, start them in peat pots, and when roots show through the pots' drainage holes, transplant the seedlings into the garden still in their pots.
Nasturtiums love cool, damp conditions and flower best in full sun. However, mine have also done well in part shade. In hot-summer areas, provide some afternoon shade, or cut them back in midsummer and allow the plants to regrow for a fall flower show.
For best flowering, grow nasturtiums in well-drained soil. They don't like excessive fertilization, especially nitrogen. If the soil is too rich, the plants will respond with large leaves and fewer flowers. Aphids are the main pests, but they seldom harm the plants unless it's a major infestation. Check the undersides of leaves for aphids, and eliminate them by spraying the plants with insecticidal soap.
