Hostas add impact to partially shaded areas of the garden. From deep greens to blues and yellows, the colorful leaves contrast well with other flowers. Propagate hostas through division of the bulbs, or rhizomes, in the early spring or late fall. Given proper growing conditions, hostas grow and bloom in the garden for many years.
Till up the soil to a depth of 12 to 16 inches with a shovel or rototiller. Remove any rocks, sticks, or other debris from the soil. Break up any large clumps of soil. Rake the garden bed smooth.
Dig a hole with a slight mound in the center of the hole, using the shovel. Locate the soil line on the stalk of the hosta where the leaves meet the rhizomes. Add or remove soil to the hole to adjust the depth so the hosta sets at the previous soil level represented by the soil line on the stalk.
Shake off any soil from the hosta rhizomes and spread out the roots as much as possible. Center the hosta onto the mound and fill the hole to the soil line. Tamp down the soil with the shovel to remove air pockets. Water the newly planted hosta. Add compost during the growing season, if desired.
Divide the hosta after allowing it to grow at least one season. Dig up the hosta in the early spring, using the shovel, and separate the rhizomes, if possible. Divide tangled masses of rhizomes by cutting straight through the middle with a sharp knife.
Replant the hostas and grow the two plants out for an entire growing season. Divide these plants the same way. Keep dividing and replanting until you have the number of hostas you want.
