Expert tips
The key tip
Let it develop naturally with minimal pruning – it takes several years to reach its full form. A light trim after flowering if it gets too sprawly.
The common mistake
Pruning hard in the first year or cutting back aggressively creates dense, stubbly growth that looks clunky and kills the elegant, graceful architecture.
The pro's trick
Plant it near a pond or stream if you can: it loves moisture at the roots.
Care
Exposure
Salix eleagnos thrives in full sun for optimal growth and generous flowering. Tolerant, it accepts partial shade but will be less vigorous. Prefer an open location, especially in cold regions where winter sun will help it get through the harsh season.
Watering
Moderate water needs once established. Water regularly during the first two years to establish good rooting. In dry climates, occasional summer watering will prolong vitality; in temperate or humid climates, natural rainfall is generally sufficient. Avoid chronic waterlogging.
Soil
This shrub prefers well-drained soil, even poor or chalky. It tolerates rocky and slightly salty soils, particularly useful in coastal or mountainous settings. Adding potting soil or compost at planting time improves establishment without strict requirements.
Pruning and maintenance
Prune lightly after flowering (June-July) to maintain balanced, thick growth. Remove dead or crossing branches. Hard pruning in spring (before bud break) is possible on an aging shrub. No mandatory pruning if space allows.
Fertilizer
Undemanding, it requires no regular fertilizer in fertile soil. An annual application of well-decomposed compost in spring supports growth. Avoid excess nitrogen which promotes foliage at the expense of flowering.
Diseases and pests
Very resistant, Salix eleagnos fears few common diseases. Occasionally watch for aphids and leaf beetles on young wood. Good drainage and adequate air circulation are sufficient to prevent fungal problems. Its natural hardiness and vigor provide the best prevention.
Did you know?
The Elaeagnus willow is remarkable for its early and strongly silvered catkins in spring, which sparkle in the sun and massively attract bees and pollinating insects early in the season. This hardy shrub is a valuable ally for alpine or coastal gardens, where few other woody plants flower as generously before April.
Where to buy it
Best planted in autumn so the roots settle in before summer, or in early spring once the frost has passed. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, October, November.
