How to Root a Snowball Plant

The snowball plant or snowball viburnum is a delicious shrub with multiple stems. At the ends of the stems, clusters of white flowers that resemble a snowball appear in mid to late spring. The snowball shrub, depending on the variety, can be a dwarf that grows to 2 feet tall and 3 feet wide, or a regular type that grows to 12 feet tall with a spread of 12 feet. If you want to add more snowball plants to your yard, they are easy to propagate from softwood cuttings taken in May, June or July.

Instructions

    • 1

      Place a coffee filter at the bottom of the 4-inch pots. The coffee filters allow the water to drain out, while keeping the soil in the pot. Prepare a pot for each cutting you have.

    • 2

      Fill the pots with potting soil.

    • 3

      Examine the snowball plant to find softwood. Softwood is flexible new growth; when the stem is bent, it will not snap or break.

    • 4

      Cut 6-inch lengths, measuring from the tip down. Each cutting should have at least three leaf nodes. Make the cut right below the leaf node.

    • 5

      Remove all the leaves except the top two to three.

    • 6

      Fill a glass with water and dip the cut end of the snowball plant to wet it. Shake off the excess water.

    • 7

      Dip the wet end into rooting hormone. Tap the stem to remove the excess rooting hormone.

    • 8

      Insert a pencil into the potting soil to make a hole, and then push the end with the rooting hormone into the hole. Firm the soil around the stem with your fingers.

    • 9

      Water the snowball plants thoroughly until water comes out the bottom drainage holes. Wait for the water to drain out of the soil.

    • 10

      Place clear plastic bags over the pots.

    • 11

      Place the pots in a bright window but keep them out of direct sunlight.

    • 12

      Check the soil daily for moisture. Keep the soil moist but not soggy. It takes a month or more for the roots to form.

    • 13

      Remove the clear plastic bags when roots have formed. Test the cuttings by pulling gently on the stem. If you feel resistance, then the roots have formed.
