The Chinese snowball bush can grow large for a shrub, reaching 10 to 12 feet in both height and spread. This can surprise gardeners, who may choose to transplant the bush to a larger, more suitable site.
Spring is the best time to transplant the snowball bush. The shrub's buds form in the summer or fall, so to avoid removing next season's blooms, transplant the snowball bush immediately after it finishes flowering.
Cut the snowball bush back to a manageable size. Cut it conservatively, and tie the branches with twine to keep them out of the way while moving it.
Water the snowball bush deeply the day before transplanting it. Water slowly until the water puddles at the base of the plant. This softens the soil to make it easier to dig up the bush.
