Instructions
After first fall frost, trim dahlia stem down to 6-inches tall.
In the next week or two, carefully dig up tubers using a spading fork.
Lay tubers out to dry for a day in a sheltered location then gently brush off excess soil.
Apply bleach treatment (1-part bleach: 10 parts water) or fungicide if disease is a concern.
With clean scissors, trim away any dead, damaged, or diseased pieces or roots.
Divide multi-tubers if desired.
Wrap each tuber in plastic food wrap or paper bags and label with name.
Store in cool, dark location with temperature of 40-45°F (4-7°C) at medium to high humidity
Check monthly and discard any rotting tubers.
Plant indoors in containers 4-6 weeks before last frost to prepare for transplanting outdoors after last frost.
