Dahlia tuber storage tips

• Store at 40-45 degrees Fahrenheit. If the tubers freeze, they will turn to mush when they thaw. If they get too warm, they could rot.

• Humidity at about 80-90%. Ensure that the tubers are not too dry (they will shrivel) and not too wet (they will rot). If your space is dry, you can control this by storing in plastic bins/bags and occasionally spritzing with water. If your space is damp, try storing in paper bags/cardboard boxes that will help absorb moisture. Peat moss, wood shavings and vermiculite will also help regulate humidity. You may need to run a dehumidifier OR a humidifier, depending on your needs.

• Check on your tubers every few weeks. Remove any rotted, mushy tubers. Mush is no good. If the tubers looks shriveled and dry, don’t toss them - move them to a more humid location. I’ve seen the most terrible dead-looking tubers come back to life in the spring.

• Sometimes the tubers develop small amount of mold. Don’t panic. It means your spot is too humid. Move them to a drier spot and simply brush off or wipe off the mold.

• FOR BEST RESULTS, we recommend trying a few different storage methods and locations. Keep notes and make observations. Until you discover what works for you.
