Keep your dahlia tubers protected through the winter with coconut coir! One of our favorite materials for storing dahlia tubers here at Fivefork Farms, coconut coir helps maintain a balanced storage environment, reducing the risk of tubers drying out during the winter months.

Made from natural coconut fibers, coir is lightweight, clean, and easy to use. Its excellent moisture-retention properties make it an ideal medium for packing dahlia tubers for winter storage.

Each compressed brick expands easily with the addition of water, producing approximately 2–2.5 cubic feet of loose coir — plenty for packing away your dahlia collection.
