Tree willows may be divided into two groups, according to the purpose for which the wood is to be utilised. One group contains trees which are pollarded with a view to the production of poles used principally for hurdles and rough fencing. The other group contains timber of larger size and under this category the most important manufactured product is the cricket bat. The cultivation of the willow is not actually difficult, but close attention to detail is necessary, especially during its early life. Many growers fail to realise sufficiently the requirements of the tree, and are accordingly disappointed in the product obtained. The large amount of timber of poor quality now produced is partly the result of lack of attention. This Bulletin provides detailed information and discussion on the cultivation and use of willow.
