Care Guide

Planting

Plant Scouler's Willow in full sun to part shade in fall or winter when the plant is dormant. This adaptable shrub tolerates sand, loam, and clay soils, so soil type is flexible, but ensure the site can handle a plant that grows 7 to 50 feet tall depending on growing conditions. Space it with room for its fibrous, widespread root system and multiple stems to develop.

After Planting

Water heavily during the first growing season and summer months, as this is a high-water plant, then gradually reduce watering as it establishes. Scouler's Willow is deciduous and will drop its leaves in winter - this is normal dormancy, not a sign of trouble. Prune in late winter or early spring while dormant if you need to shape it or manage its multi-stemmed growth; the main mistake is overwatering once established or planting it in a spot where it can't access consistent moisture.
