Storing Dahlia Tubers for Winter

After finally getting all of the dahlia tubers out of the ground, I feel like I’m finally making progress in preparation for spring. Today, I wanted to talk a little bit more about storing the tubers for this winter, since this always seems to be the hardest part for me. Ideally, dahlia tubers should be stored somewhere dark and cool. While I’ve always heard that the ideal temperature is around 45F, my basement will simply have to do the job.

Before storing the dahlia tubers, I made sure to rinse them well with water and let them dry about a day outdoors. I also made sure to remove as much of the main stem as possible and any of the smaller feeder type roots on the tubers.

Next, I packed them up into boxes and totes that are filled with coarse vermiculite. Though I’ve stored dahlia tubers in other materials in the past, I find that the vermiculite really does the best job when it comes to regulating moisture.

These boxes will be stored in a dark closet. Every month throughout the winter, I’ll need to check on them and make sure that none of the tubers are rotting or have any issues concerning mold. This will be key in keeping all the tubers looking healthy and plump. How do you store dahlia tubers? I would love to hear all about your experiences in the comments below. Thank you so much for stopping by!
