Distribution of Grey willow

Distribution Map

Grey willow, which is cultivated, naturally thrives across temperate regions of both Eastern and Western Europe, as well as parts of Asia. It has been introduced to other major regions, showing adaptability to new environments. In certain areas like New Zealand, grey willow may be seen as a plant that could potentially have an impact on local ecosystems, though it is not categorically invasive globally. The plant's adaptability is evident in its cultivation beyond its native habitat, indicating a level of resilience and utility in varied climates and soils.

Garden Use

Mature grey willow is appreciated by gardeners for the diamond pattern of its bark. Flourishing in damp soil, this deciduous tree will perform best when planted in gardens near ponds or streams in meadows. It can also grow well in gardens in coastal areas.

Interesting Facts

In native habitats where several species of willow are present, they can hybridise, which sometimes makes it hard to make a correct identification. Grey willow will often hybridise with goat willow (Salix caprea), and also can be confused with the same species because of similar male catkins. Grey willow is a very important food source for wildlife, including pollinators (nectar) and caterpillars of stunning butterflies such as the Purple emperor (leaves).

Name Story

Grey willow: This species of willow is referred to as grey because of the greyish tint of leaves, and also the grey colour of male and female flowers (catkins). The male catkins will turn yellow in time as they release their pollen.

Care Guide for Grey willow

Every 3 weeks

Water

Sunlight

5 - 32 ℃

Ideal Temperature

Water: Grey willow thrives in moist, humid environments and prefers consistently damp soil, requiring watering every three weeks. Typically found outdoors, it adapts to various climates and supports local ecosystems as a deciduous plant that contributes to moisture cycles through seasonal leaf drop.

Fertilize: Grey willow requires balanced fertilizers, benefiting from high nitrogen during spring's active growth. Fertilize biannually in early spring and mid-summer, avoiding trunk contact. Adjust during dormancy and water regularly post-application. Novice gardeners should wear gloves and follow package directions to prevent overfertilization.

Pruning: Grey willow thrives with early spring pruning, focusing on dead branches to promote growth and improve air circulation. Maintain shape by trimming overgrown shoots, using clean tools. Avoid heavy pruning in late summer to protect new growth. Consistent care enhances its vitality and appearance.

Propagation: Propagate grey willow using fresh seeds in a well-draining, fertile substrate. Position in partial shade and maintain consistently moist soil, avoiding stagnation to prevent root rot. Incorporate organic matter for moisture retention while ensuring adequate drainage.
