When should I pull my dahlias for the winter?

Dahlias are tender annuals, but you can overwinter them pretty easily.

Allow tubers to dry for a few days in a frost-free location, out of direct sunlight.

Herein, how do you prepare dahlias for winter?

Cut off the foliage and carefully dig out the tubers. Brush off excess dirt and let the tubers dry for a few days. If possible, hang them upside down when drying them so that moisture can leach out of them. Drying is important to saving dahlias over winter and preventing them from rotting.

How do you prune dahlias?

Pruning to Encourage Flower Growth. Pinch the tips off of dahlias once they reach 16 in (41 cm). When the dahlia first starts growing, it will develop 4 sets of leaves. Pinching off the top of the plant above the fourth set of leaves will encourage branching, resulting in a fuller plant and therefore more flowers.

Can you store dahlia tubers in sawdust?

It is best to store your dahlia tubers in vermiculite, peat moss or sawdust. Putting them into potting mix will work, since it is mostly peat and perlite.
