Or start seeds indoors in individual eight-centimetre peat pots four to six weeks before the last frost date. Feed them twice a month with a diluted solution of fertilizer to keep them blooming until fall's first frost. Nasturtiums symbolize patriotism and splendor, and in spite of the fact the nasturtium is not a special flower for any month, its blooms always appear to smile. As a bonus, the flowers and leaves taste similar to watercress and make a colourful and tasty addition to tossed salads. A week or two before the last frost date, sow seeds in full sun or part shade, one centimetre deep and 15 centimetres apart, in ordinary garden soil.
Nasturtiums dislike being transplanted, but tolerate heat, drought and poor soil.
In fact, if the soil is too rich the plants produce lush leaves with few flowers. They grow best during cool weather, blooming until frost. All rights reserved.
