I love dahlias and have been growing them for years. Just when other flowers are giving out, dahlias put on their best show. Flowers vary in color, size and type and are easy to grow. They do best staked, in full sun & like fertilizer that is low in nitrogen. (Stake them when planting the tubers.) Dahlias are wonderful as cut flowers - put freshly cut stems in hot water to start and they will last longer.
