If your area is not yet free of frost, store all of the dahlia bulbs/tubers in a dry, airy place where the temperature stays in the 60-65 degree Fahrenheit range, until the danger of a hard frost has passed. Plant dahlias about 3 inches deep and 12 inches apart in a well-drained, sunny area. Deep watering 1-2 times a week is necessary during warmer, dryer weather. Hotter climates will need to water more often as conditions require. Proper watering promotes better blooming. Do not allow the tubers to stand in water.
