Nordic Biomass has established one of Denmark’s largest willow arboretums containing more than 80 different varieties and great variation in colours and catkins. Professional propagation ensures that willow windbreaks and plantations can be established with botanical variety and within a reasonable budget.

 
 

Small forest stands provide habitats for wildlife and welcome variation in an otherwise intensively cultivated landscape. Example applications include:

  • Recultivation and pioneer planting at construction sites, industrial plants and road works, rest areas, garbage dumps and polluted soils.
  • Nurse trees and coverts. Lake shore protection and fascines.
  • Sand drift/coastal protection. Salt-resistant willow, whose natural habitat is along the coast, can be well-suited to these applications. For example, Salix Repens.
 
   
 

There are many different varieties of willow, from bushes to trees, broad-leafed and narrow-leafed – and in innumerable leaf and stem colour variations. Depending on the variety, trees can either be fast or slow growing, and if varieties are carefully selected, variegated willow plantations can be established. Fast growing willow is ideal for establishing coverts, windbreaks and to serve as nurse trees.

In order to achieve good results, it is important that the willow receives plenty of light. It is therefore not recommended that willow be planted in shady areas, but nearly all soil types can be used if the correct variety is chosen. Where possible, it is recommended that willow trees be planted in appropriately spaced rows, permitting machinery access for weed control and willow harvesting. Depending on local conditions and weed control options, cutting lengths vary from 20-80 cm and from 1-4 cm in diameter.

 

Willow has a reputation as a hardy plant – and it is. Light fertiliser can be applied in the second year after establishment, as this will have a positive effect on the willow’s shoot and root growth. However, during the establishment phase, the most important thing is to keep the cuttings weed-free until the growth is so intense that weeds can be out-competed. Depending on the stump height chosen during willow cutback, denser growth or single-stemmed growth can be created. One year after cutback, willow will typically have reached a height of 1.5-2m, depending on the variety. Willow tree varieties can grow to maximum heights varying from 30 cm to 25-30 m.
