WaterDoublefile viburnum should be watered deeply and slowly to ensure the water reaches the root zone. During the first growing season, it's essential to maintain consistent moisture, watering about 1 inch per week. Adjust the amount depending on rainfall, less in wet periods and more during dry spells. As the plant becomes established, it will require less frequent watering but should still be done thoroughly, especially during extended periods of drought. Overhead sprinkling is less ideal than drip irrigation or a soaker hose, which delivers water directly to the base of the plant.
LightDoublefile viburnum thrives in full sun to partial shade. Ideally, it should get at least 4 to 6 hours of direct sunlight every day. If you're in a particularly hot and sunny climate, providing some afternoon shade will help protect the plant from the intensity of the midday sun. This shrub is versatile, but too much shade can result in reduced flowering and a less dense growth habit.
TemperatureDoublefile viburnum is hardy and can handle a range of temperatures, typically between 5 to 30°F for short periods. The ideal growing temperatures are between 60 and 75°F. Established shrubs are cold hardy down to about -10°F, making them suitable for USDA hardiness zones 5 to 8.
PruningPrune doublefile viburnum to maintain shape and promote healthy growth. It's best to prune just after the shrub finishes flowering in late spring or early summer to avoid cutting off next year's blooms. Remove any dead or damaged branches and thin out dense areas to increase light penetration and air circulation within the canopy. Pruning can be done annually, but heavy pruning should be infrequent, as this plant responds well to minimal, careful trimming.
CleaningAs needed
SoilDoublefile viburnum thrives in well-draining, moderately fertile soil with a pH of 5.6 to 6.6. A mix of garden soil, compost, and peat moss is ideal to retain moisture while providing good drainage and nutrients.
RepottingDoublefile viburnum, being a large shrub, is not typically repotted as it is commonly planted directly in the ground. Repotting is only relevant for very young plants, which may need repotting every 2-3 years until established in the landscape.
Humidity & MistingDoublefile viburnum prefers average humidity levels consistent with outdoor conditions. It does not require any special humidity adjustments when planted in its natural outdoor environment.
Suitable locationsIndoor

Life cycleViburnum plicatum f. tomentosum 'Dart's Red Robin', commonly known as Doublefile Viburnum, starts its life cycle as a dormant seed which requires a period of cold stratification to break dormancy and germinate. Upon germination in early spring, the seedling emerges and develops into a young plant, experiencing rapid vegetative growth and establishing a root system. As the plant matures, it forms a rounded shrub with horizontally spreading branches and begins its reproductive phase, producing white, lacecap flowers typically in May which are followed by red to black fruit that matures in late summer to fall. The fruits not only add visual interest but are also attractive to birds and wildlife, aiding in seed dispersal. Doublefile Viburnum subsequently enters a period of dormancy during winter, when growth ceases and the plant conserves energy. Throughout its life, if provided with the appropriate growing conditions including well-drained soil and full sun to partial shade, the shrub can live for many years, repeating its annual cycle of growth, flowering, and dormancy.
PropogationPropogation time
Early Summer
The most popular method for propagating Viburnum plicatum f. tomentosum 'Dart's Red Robin', commonly known as the Doublefile Viburnum, is through softwood cuttings. This technique is usually performed in late spring or early summer when new growth is still tender but has begun to mature. Cuttings should be about 4 to 6 inches (approximately 10 to 15 centimeters) long and include at least two sets of leaves. The lower leaves are removed, and the cut end is dipped in rooting hormone to encourage root development. The treated cutting is then inserted into a well-draining potting mix and kept under high humidity with moderate indirect light until roots have formed, which can take several weeks.
