arrowwood viburnum

Arrowwood viburnum should be watered well when first planted, and then, once established, should be watered every 7-10 days. The frequency of watering will depend on the soil type, sunlight, and temperature. In general, arrowwood viburnum should receive 1-2 inches of water per week during pronounced dry spells to keep the soil moist, but not soggy. During the hottest periods of the growing season, it may be necessary to water every 5 days.

Arrowwood viburnum (Viburnum dentatum 'Christom' BLUE MUFFIN) should receive at least 6 hours of sunshine each day, ideally in the form of direct, morning sunlight. While it can tolerate partial shade, too much shade can result in decreasing flower production and foliage color. During the hottest parts of the day, when temperatures are highest, the plant can benefit from some afternoon shade, such as with a filtering screen or light shade cloth. This will also protect it from any potential drying winds or strong sun that could cause leaf scorch.

Arrowwood viburnum (Viburnum dentatum 'Christom' BLUE MUFFIN) should generally be pruned in late winter, after it's finished flowering. Pruning should be kept to a minimum to prevent harming flowering buds, but should remove noticeably dead wood and remove crossing branches or branches that are growing too close together. Head the entire plant back by a third (no more!) to keep it full and manageable. Make sure to make cuts just above an outward-facing leaf or shoot so that new growth is able to directly outward, not inward.
