Every experienced fruit grower knows the advantages of windbreaks. At Norfolk, Va., windbreaks of trees are extensively planted. They are especially valuable in the protection of field cucumbers; the young plants advance much more rapidly where such windbreaks have been established than on unprotected land. A common practice is to construct board windbreaks to shelter hotbeds and cold frames, although hedges are more attractive and more economical to establish. Natural windbreaks of trees or hills are most desirable of all.
