Growing Willow (Salix): Trees, Shrubs & Container Standards

Salix (Willow) – Diverse Genus for Sun, Moisture & Fast Growth

Pronunciation: say'-licks

Diverse woody trees and shrubs from riverbanks to arctic shores. Thrive in full sun or partial shade in average to moist, well-drained soil.

Tree Forms – Planting

1. Soak roots 1 hour in 5-gallon bucket of water before planting.
2. In ground: Dig hole wide/deep for roots. Plant crown at label depth, arrange roots evenly. Firm soil, water thoroughly.
3. In container: Use 14–16 inch diameter pot with quality potting soil. Place outdoors for season. Water regularly—containers dry faster.

Staking Standards

Keep out of strong winds. Support with stake at least as thick as stem, long enough to reach inside head. Fasten with figure-eight loops of twine or green tie tape at several points. Check ties periodically; loosen if constricting stem.

Pruning, Fertilizing & Repotting

• Maintain head shape with selective pinching of new shoots (too much prevents flower buds). Pinch between thumb/forefinger or prune shears. Do not shear like hedge.
• Fertilize potted standards as other pot-grown plants: balanced time-release fertilizer.
• If container dries quickly after watering, needs larger pot. Lift, make 4 deep vertical cuts in root ball, repot in pot 2 inches wider/taller, fill with fresh mix, water thoroughly.

Overwintering Containers

• Zones 5–6: store in sheltered unheated area (garage/shed) at 25–40°F. Check moisture occasionally; water as needed.
• Warmer climates with freeze-thaw: protected porch.
• No freezing concern: remain outdoors year-round.
