Koreanspice viburnum

Water Koreanspice viburnum (Viburnum carlesii 'Compactum') consistently during its first growing season, giving it 1 to 2 inches of water weekly. After it has become established, reduce watering to every 2 to 3 weeks, or until the soil has become dry. In periods of extreme drought, water every 3 to 4 weeks. In climates with a good amount of rainfall, no additional watering will be required during autumn and winter.

Koreanspice viburnum (Viburnum carlesii 'Compactum') should be grown in an area that receives full sunlight to partial shade. They prefer at least 4 to 6 hours of direct sunlight each day when planted in full sunlight. In partial shade, they should receive 4 hours of sunlight and the rest of the day in the shade. This type of viburnum can even be grown in full shade but won’t produce as many flowers or berries as it would with more sunlight.

Koreanspice viburnum should be pruned in late winter or early spring, before it begins to bud. Pruning helps to maintain the desired size and shape. Light pruning of Viburnum carlesii 'Compactum' is recommended once a year to encourage new growth. This means that all of the growth that has occurred during the past season (or possibly 2) should be removed. Shoots from the base of the plant should be pruned to the ground to encourage new, dense shrub growth. Pruning older plants should include removing older woody shoots to reveal the fresh foliage below and maintain an attractive overall shape and form. Be sure to use sterilized pruning shears and dispose of clippings after pruning.
