#ProPlantTips for Care:
Thomas Edison enjoys moist, organically rich soils in full sun and sometimes partial shade in hotter growing zones of USDA zones 9-10, Dahlia tubers can be lifted (dug up) in fall after frost and stored in growing zones 1-11. Preferring a wide range of soil types, clay, and acidic conditions, as long as they're planted in well-drained locations. To ensure even moisture, place mulch around the base of the plant. Adding mulch can add to the overall physical appearance of your landscaping to make it look clean and put together.
The foliage will fade in the fall and wilt with colder nights. In very cold climates, to save your tubers for the next year, dig up the plants after the first frost. Let them dry out, and then place in paper bags or boxes in a cool place. Throughout the winter, sprinkle a little water if the tubers are drying up. If you live in a warmer frost-free climate, just trim out stems to keep your plants looking their best; fresh growth will appear in the spring.
