Short Rotation Coppice Willow Ely
Salix viminalis × alba 'Ely'
treeEly is a hybrid willow cultivar bred specifically for short rotation coppice (SRC) forestry and biomass production. It is a fast-growing deciduous tree that can be harvested every 2-3 years for renewable energy, pulp, or biofuel. The variety is known for its vigorous growth, disease resistance, and high yielding characteristics.

Establishment
3-6 months after plantingBare-root cuttings develop root systems and initial shoots emerge from buds. Growth is moderate in the first year.
Keep soil consistently moist. Remove competing weeds. Apply mulch. Stake tall plants if needed. Avoid herbicide damage to young shoots.
Vegetative Growth Year 1-2
12-24 monthsRapid shoot elongation occurs, reaching 4-6 feet by end of year 1. Multiple branches develop from the main stem.
Maintain soil moisture during dry spells. Apply balanced fertilizer in spring of year 1. Remove any dead or diseased shoots. Monitor for pests and diseases.
Pre-Harvest Maturation
12-18 months before harvestPlant reaches harvestable size (8-15 feet tall, finger-thick stems) by year 2-3. Stem diameter thickens and wood matures.
Continue weed management. Apply nitrogen fertilizer in early spring to boost final growth. Monitor pest populations as trees mature.
Coppice Regrowth
24-36 months per rotationAfter harvest, dormant buds on the stump rapidly sprout, producing multiple shoots from a single root system. Growth is faster in subsequent rotations.
Ensure clean, angled cuts during harvest to promote drainage. Nitrogen fertilization post-harvest accelerates regrowth. Manage competing vegetation.
Long-term Management
Ongoing (8-20 years typical)The root system becomes established and productive over multiple harvest cycles (8-20+ years of useful production).
Monitor stool (base) health. Replace declining plants. Maintain soil fertility with periodic nutrient applications. Harvest on consistent 2-3 year cycles.

Common Pests
-
Monitor foliage regularly; heavy infestations are rare in SRC systems. Encourage natural predators; pesticide use generally not economical.
-
Monitor larvae on leaves; minor feeding is typically tolerable in energy crops. Hand-remove heavily infested shoots if needed.
-
Usually controlled by natural predators. Spray with strong water stream or insecticidal soap if severe.
-
and
Protect young plants with fencing (at least 6 feet tall). Netting or tree guards on individual stems.
Uses
Renewable Energy & Biomass
HouseholdEly willow is cultivated specifically for renewable energy production, with harvested stems chipped and burned in biomass heating systems or converted to biofuel. It is a carbon-neutral or near-carbon-neutral energy source. [source]
Pulp and Paper Production
HouseholdThe fast-growing wood is suitable for pulping and paper manufacture, offering a sustainable alternative to traditional timber harvesting. [source]
Habitat and Biodiversity
WildlifeWillow plantations provide nesting sites, food, and shelter for numerous bird species, insects, and small mammals. SRC systems can enhance landscape biodiversity. [source]
Carbon Sequestration
HouseholdShort rotation coppice willows sequester atmospheric carbon in biomass and can be part of carbon offset and land restoration programs. [source]
Wastewater Treatment and Phytoremediation
HouseholdWillow plantations can be irrigated with treated wastewater and are effective at removing excess nutrients (nitrogen and phosphorus), serving environmental remediation purposes. [source]
Harvest Tips
Harvest in late autumn through early spring when the plant is dormant and wood moisture is lowest. Cut stems 1-2 inches above the stool (base) at an angled cut to promote drainage and prevent rot. Mechanical harvesters are commonly used in large-scale SRC operations. Remove and chip or comminute biomass promptly. Ely typically yields 8-12 oven-dry tons per hectare per year (3.2-4.8 tons per acre).
Fun Facts
- 🌱 Ely willow was bred in the UK and is one of the most widely planted SRC cultivars in Europe due to its exceptional yield and disease resistance.
- 🌱 A mature short rotation coppice plantation can be harvested 8-15 times (every 2-3 years) before the root system declines, with some systems remaining productive for 20+ years.
- 🌱 Willow biomass has been used as renewable energy in Northern Europe for decades, with some power plants burning over 100,000 tons of willow chips annually.
