Step 1: Watch for the First Fall Frost to Blacken Foliage
Trim stems back to 6 inches (15 cm) with pruners. Use a fork to lift the tubers, label them, and store upside down for two weeks.
Step 2: Watch for Tubers to Dry Out
Once they have, place them right side up in boxes of dry vermiculite, and keep them in a cool, dry, frost-free place over the winter. Check the stored tubers regularly; if any mildew or rot has developed, cut it out with a clean, sharp knife, and dust with fungicide powder.
Step 3: Plant Tubers in Pots of Fresh Compost Once Spring Arrives
Grow the tubers inside, then plant outside when the frosts are over. For tall dahlias, add a stake when planting.
