WaterWillowleaf cotoneaster should be watered deeply but infrequently, allowing the soil to dry out slightly between watering sessions. During the growing season, water the plant once a week with about 1-2 gallons of water per session, depending on the size of the plant and environmental conditions. In the winter months, reduce watering to once every two weeks or less, monitoring the soil moisture level and adjusting accordingly. Overwatering can lead to root rot, so it’s essential to ensure good drainage and avoid letting the plant sit in waterlogged soil.
LightWillowleaf cotoneaster thrives best in full sun to partial shade. It should be placed in a location where it receives at least six hours of sunlight daily. The ideal spot would be one that offers morning sun and some afternoon shade, especially in regions with very hot summers. However, the plant is adaptable and can tolerate a range of light conditions, though flowering and berry production may be reduced in too much shade.
TemperatureWillowleaf cotoneaster is hardy and can withstand a range of temperatures; it can survive minimum temperatures down to about -20 degrees Fahrenheit and is suitable for growth in USDA zones 6 through 8. The ideal temperature for this plant is between 60 and 70 degrees Fahrenheit. It can endure short periods of higher temperatures, but providing some afternoon shade in extremely hot weather can prevent stress on the plant.
PruningPruning willowleaf cotoneaster is vital to maintain its shape, remove any damaged or diseased branches, and encourage new growth. Prune the plant in late winter or early spring before the onset of new growth. Occasional thinning of the branches may be needed to improve air circulation. If the plant becomes too large or unruly, you can also perform rejuvenation pruning by cutting back one-third of the oldest stems to the ground.

Life cycleCotoneaster salicifolius 'Avonbank', commonly known as Willowleaf Cotoneaster, begins its life cycle as a seed, often spread by birds that consume the fruit. Once germinated, the young seedling establishes roots and a shoot system, gradually maturing into a dense, woody shrub with long, arching branches. As the plant matures, it produces small white or pinkish flowers in the spring, which are important for attracting pollinators. Following pollination, these flowers develop into small, red pomes (berry-like fruits), which mature by late summer or early fall, providing food for wildlife. Throughout its life, the Willowleaf Cotoneaster experiences seasonal growth cycles, with active growth in the spring and summer, followed by dormancy during the winter months. Without human intervention, this shrub can live for several decades, continuously reproducing through its fruits and contributing to the local ecosystem through its role as a habitat and food source for various species.
PropogationPropogation time
Spring
Cotoneaster salicifolius 'Avonbank', commonly known as Willowleaf Cotoneaster, is most effectively propagated by semi-hardwood cuttings. This technique is typically done in late summer. To propagate by cuttings, a 4 to 6 inch long piece of semi-hardwood stem from the current year's growth is selected. The lower leaves of the cutting are removed, and the cut end is dipped in a rooting hormone powder to encourage root development. The prepared cutting is then inserted into a pot filled with a well-draining potting mix, with at least two sets of leaf nodes buried in the soil. The cutting should be kept moist and in a warm environment with indirect light. Roots generally develop within a few weeks to a few months, after which the new plant can be gradually acclimated to outdoor conditions before planting it in its final location.
