How to Grow Korean Spice

Select a site in full to partial sun to grow Korean spice viburnum. Till and incorporate 2 to 4 inches of organic matter, such as compost or leaf mold, into the top 6 to 8 inches of soil to improve drainage and soil fertility.

Water the shrub in its nursery container until the water drips out the drainage holes. Do this one day before transplanting it to the garden.

Dig a hole that is two times as wide as the Korean spice’s container. The depth of the hole should be the same depth as the container.

Remove the viburnum from its nursery container. Slide a knife along the inside of the container if it’s stuck.

Set the shrub upright in the center of the hole. Backfill the soil and pack it lightly around the Korean spice shrub.

Water the shrub thoroughly with 1 inch of water after planting. Water near the base of the shrub rather than from above since fungal diseases are more prone to spread when the leaves are wet. Continue to water a Korean spice about once a week during the growing season, especially during a hot, dry summer.

Prune a viburnum shrub about once every five to six years in the late spring or early summer after blooming. Prune to remove misshapen and broken branches. Prune branches that do not bloom or bloom well. Cut branches off just above a leaf node or parent branch with clean pruning shears.
