Arrowwood Viburnum Viburnum 'Le Bois Marquis' (PBR)

Water

The Arrowwood Viburnum should be watered deeply once a week during its growing season, ensuring moisture reaches the roots. In hot and dry conditions, increase the frequency to twice a week, supplying about 1 inch of water each session. During winter or when the plant is dormant, reduce watering to twice a month, or when the topsoil feels dry to the touch, to avoid overwatering. Always check the soil moisture level before watering to make certain the plant is not being over-irrigated.

Light

Arrowwood Viburnum thrives in full sun to partial shade. The ideal spot for this plant would be in an area where it can receive at least 4 to 6 hours of direct sunlight daily, supplemented with light, dappled shade during the hottest parts of the day to protect it from scorching. Avoid deep shade locations as this could hinder its growth and flowering potential.

Temperature

Arrowwood Viburnum grows best in a range of temperatures, ideally between 60 to 75 degrees Fahrenheit. It can tolerate cold down to about -10 degrees Fahrenheit, but should be protected from extreme cold spells. This plant is quite hardy and adaptable, but consistently extreme temperatures outside of its comfort zone could cause stress.

Pruning

Prune Arrowwood Viburnum to maintain shape and encourage healthy growth, typically after it flowers in late spring to early summer. Remove dead or diseased branches, and thin out old wood to rejuvenate the plant every few years. Pruning can also be done to control the size of the shrub if necessary, but always prune moderately to avoid excessive damage.

Cleaning

As needed

Soil

For Viburnum 'Le Bois Marquis', commonly known as Arrowwood viburnum, the best soil mix is well-draining with high organic matter. A mix of garden soil, compost, and peat moss is ideal. This plant prefers a slightly acidic to neutral soil pH of 5.6 to 7.0 for optimal growth.

Repotting

Arrowwood viburnum typically does not require frequent repotting as it is a slow-growing shrub. When grown in containers, it may need repotting every 3 to 5 years to refresh the soil and provide room for root growth.

Humidity & Misting

Arrowwood viburnum is adaptable to a range of humidity levels and does not require specific humidity conditions. It thrives in outdoor environments where the humidity naturally fluctuates.

Suitable locations

• Indoor

  Place in bright light, water when topsoil is dry.

• Outdoor

  Full sun to partial shade, moist, well-drained soil.

• Hardiness zone

  5-8 USDA

Life cycle

The life cycle of Viburnum 'Le Bois Marquis', commonly known as the Wayfaring Tree, begins with seed germination, which typically occurs in a moist, well-drained soil environment. Following germination, the seedling stage is characterized by initial shoot and root development as the young plant establishes itself. After the seedling phase, the plant enters the vegetative stage, where it develops a robust root system and foliage, eventually forming a mature shrub. As the Wayfaring Tree reaches maturity, it enters the flowering stage, producing clusters of creamy white flowers that are succeeded by berry-like fruits (drupes) if pollination occurs. These fruits facilitate seed dispersal, either by animals or natural elements, leading to a new generation of plants. Finally, as a perennial, the Wayfaring Tree may go through multiple cycles of growth, flowering, and seed production throughout its lifespan, which can be several decades long.

Propogation

• Propogation time

  Spring-Early Summer

• The Viburnum 'Le Bois Marquis', also known as the Arrowwood Viburnum, can be propagated most commonly through semi-hardwood cuttings. This method typically takes place during the late summer months. To propagate, one would cut a semi-hardwood stem that has matured slightly from the current year's growth. The cutting should be about 4 to 6 inches (approximately 10 to 15 centimeters) long, with several leaves attached. To encourage rooting, the bottom end of the cutting is often dipped in rooting hormone powder before being planted in a well-draining soil mix. The soil should be kept consistently moist but not waterlogged and the cuttings should be placed in indirect light. With proper care, roots will usually develop within a few weeks.
