Protecting the Dahlia Tubers for the Winter

My dahlia tubers are now well-protected for the winter.

When in bloom, dahlias provide some of the garden's biggest and most spectacular flowers in many different sizes, forms, and colors. However, native to Mexico, dahlias are not winter-hardy and tend to split in freezing temperatures or mold in soggy, wet soil. In most areas outside the warmest regions of the United States, dahlia tubers must be dug up and stored or covered before the cold season. In previous years, we've always uprooted our dahlias and kept them indoors for the winter. Now, we cover the entire bed with burlap and a thick layer of hay. It's proven to be a great solution for protecting the plants so we have viable dahlias come spring.

Here are some photos, enjoy.
