Dahlia General Information
Dahlias are annual bulbs and tubers available in a variety of forms and colors from smaller starburst blossoms to plate-size flowers. Gardeners adore their easy-growing disposition and the flowers are favorites for cut flower arrangements. Their bursts of colorful flowers provide months of summertime color. Dahlias will only last one year (except in zones 8-10) but can be lifted and stored over the winter in colder zones. Here are Instructions for doing that. Our Dahlias are guaranteed to reach you in good condition and to grow, but our guarantee does not cover winter losses.
Dahlia Plant Care
Dahlia flowers are generated from tubers which prefer well-drained loamy soil that does not stay soggy. To prepare soil, dig down 8-12 inches and add compost to planting hole. Lay the tuber sprout-side up 3 inches deep and cover with soil. Water sparingly until first sprouts are produced then increase to 2-3 times per week. Do not let them dry out for long periods. Dahlias will return next year in zones 8-10, but tubers can be lifted, overwintered, and replanted in zones 3-7 by following these Instructions. Dahlias can be started indoors four to six weeks before the frost free outdoor planting date if desired, then transferred outside when danger of frost has subsided.
