The weeping pussy willow, scientifically known as Salix caprea ‘Pendula’, is an ornamental tree cherished for its graceful, cascading branches. This deciduous plant is celebrated for its soft, fuzzy catkins, which emerge in late winter or early spring before its leaves. Its compact size makes it a popular choice for adding early seasonal interest to various garden settings.
Planting Weeping Pussy Willow
Establishing a healthy weeping pussy willow begins with selecting an appropriate site. This tree thrives in USDA plant hardiness zones 4 through 8. It performs best in full sun but tolerates partial shade, provided it receives some afternoon sun. It adapts to various soil types, preferring moist, well-drained conditions and tolerating some standing water.
The optimal time for planting is in spring or autumn, allowing the tree to establish before extreme temperatures. Dig a hole that is twice as wide and deep as the root ball. Position the tree with the top of the root ball level with the soil, then backfill, gently tamping to remove air pockets. A small soil wall around the base helps form a watering basin. Staking young trees may be necessary for support until roots are anchored.
Watering and Fertilizing Weeping Pussy Willow
Consistent moisture is important for the weeping pussy willow, as it prefers moist soil and looks best with regular watering. Young plants and newly established trees require more frequent watering, often every 2-5 days, until their roots are well-developed. Mature plants have some drought resistance, but weekly watering is beneficial, especially during dry periods. To assess soil moisture, check about 2 inches below the surface; water if it feels dry.
The weeping pussy willow is not typically a heavy feeder, especially if planted in rich soil. If soil quality is poor or a nutrient deficiency is suspected, a balanced, all-purpose fertilizer can be applied once in early spring before new growth begins. Organic compost or leaf mold can also enrich the soil. Avoid over-fertilizing, which promotes excessive foliage at the expense of catkin production.
Pruning Weeping Pussy Willow
Pruning is important for maintaining the weeping pussy willow’s characteristic form and promoting healthy growth. The best time for significant pruning is in late winter or early spring, before new growth emerges. This allows the tree to recover quickly and encourages a robust catkin display the following year. Light pruning can also be done after catkins fade to refine the tree’s shape.
Since weeping pussy willows are typically grafted, they will not grow significantly taller than their original height. Focus pruning efforts on removing any shoots that sprout from the trunk below the graft union, as these will revert to undesirable growth. Trim branches that grow upwards, inwards, or cross over others to maintain the open, weeping shape. Thinning smaller branches and removing older, thicker ones improves air circulation and the tree’s appearance.
Addressing Weeping Pussy Willow Problems
Weeping pussy willows are generally resilient, but they can encounter certain issues. Common insect pests include aphids, scale insects, and willow sawflies. Aphids can be managed with water or neem oil; severe scale may require treatment. Diseases like powdery mildew, canker, rust, and leaf spots can also affect these trees. Prompt removal of affected branches limits disease spread.
Yellowing leaves often indicate too much or too little water, or a nutrient deficiency. Checking the soil moisture and adjusting watering practices is an initial step. If water levels are appropriate, a balanced fertilizer may address nutrient deficiencies. Weeping pussy willows have soft, fast-growing wood, making them susceptible to structural damage from heavy ice or snow. Siting the tree in a sheltered area can mitigate this.
