WINDOW GARDENS
Window boxes may be used for a whole season on the inside of the building in cold weather, and on the outside in warm weather. There is almost no limit to the kinds of plants that can be grown in them, but they are most suitable for flowers.
Good boxes may be made of dressed lumber so as to fit on the window-sill. They should be six inches deep, ten inches wide, and the required length. They should have a few small holes in the bottom to allow excess water to drain off and should be painted dark green or some quiet colour. There should be an inch of gravel in the bottom, some rotted sods covering this, and then the box filled with rich sandy loam.
