Hydrangeas are beautiful flowers that, in many climates, can be enjoyed year round. Hydrangeas are relatively low maintenance, and can be rooted successfully during the winter by any garden enthusiast without the need for expertise. Rooting hydrangeas in the winter is a simple process that requires good potting soil and a simple solution for dipping hydrangea roots.
Place 1 cup of good potting soil into a plastic or clay pot. If you wish to root more than one hydrangea plant, prepare one pot with 1 cup soil for each hydrangea you wish to root.
Use your scissors or pruning shears to cut your hydrangea plant into 5-inch stems. Make sure that each stem contains at least one hydrangea plant leaf.
Pour one cup of warm water into a drinking glass. Place 1/4 teaspoon of rubbing alcohol into the water and stir. The alcohol serves to prevent bacteria and disease from growing onto your hydrangea.
Cut the hydrangea stem directly down the middle with your scissors or pruning shears.
Dip the sliced hydrangea stem into the water/alcohol solution for five seconds.
Place the hydrangea stem directly into the center of the soil pot.
Store the plant indoors during evenings when the temperature is below 40 degrees.
