One of the exciting stages of garden construction is the marking out of beds. The sites for the flower displays are marked out in the garden in the form of beds or borders. These may be of various shapes and sizes and much will depend on the character of the garden as to the exact shape which is used. Formal beds are those which have straight, defined edges whereas the informal types have irregular or natural edges. It is a good idea to draw up scale plans on paper before any marking out is begun. This will enable the gardener to design and measure the beds accurately especially where it is necessary to accommodate collections of plants such as shrubs and herbaceous plants.
