European cranberrybush

European cranberrybush should be watered once a week or as needed, depending on the level of rainfall in your area and the temperature. During hot, dry periods you may need to increase the amount of water to keep the soil slightly moist at all times. Generally, water slowly and deeply at the base of the plant, until the water begins to slightly puddle. Allow the water to absorb for about 15 minutes and then check the soil again. The soil should feel moist to the touch 1 to 2 inches down. If not, water for an additional 10-15 minutes.

European cranberrybush thrives best in full sunlight, and requires at least 6–8 hours a day of direct sunlight to reach its full potential. In the summer months, when the sunlight is strongest, it will benefit from 8–10 hours a day of direct sunlight. To ensure the European cranberrybush receives sufficient light year-round, plant it in a location that receives full sun most of the day. In the winter months, the shrub may need additional lighting to help it get through the darkness.

European cranberrybush (Viburnum opulus) should be pruned in late winter or early spring, before new growth begins. The best time to prune European cranberrybush is when the plant is dormant, as this will promote strong growth when the new growth appears later in the season. Pruning can be done either lightly or heavily, depending on the desired size. Light pruning involves the removal of dead, diseased, or damaged branches, while heavier pruning reduces the size of the bush by removing large branches. Pruning back up to 1-third of the bush will promote growth of healthy new branches and increase flowering. Certain shoots may require thinning out to promote air circulation and reduce disease.
