Windows with flower boxes are, said more exactly also a "facade greening" a selective partial greening. Sometimes, for example, they are with insulation or also then the only opportunity for walls to score a little green to a facade when no possibility exists to grow plants from below. Therefore we show greening that has been successful here with window boxes, flower traffic lights and the like. You can find detail photos examples of the combination of window boxes and extensive facade greening to the fastening and safeguarding against falling down and furthermore, too.
Window boxes are often made of sheetmetal, high-grade steel, special woods, but most are synthetic material -plastic- today. Ingenious constructions of storage and eutrophication leading up to automated grass planting systems can be found today. Many other plants are suitable for planting next to the usual geraniums you buy from regional flower stores and garden centers.
Small solutions usually aren't convincing when designing window boxes because a single flower box on a big wall seems almost lost. Therefore as many possible windows should be fitted, e.g. all windows of a house floor with boxes. For a uniform phenotype it is appropriate, often simple to fit all windows of a facade with window boxes, generally speaking.
Window boxes are usually put on an available window sill. If a sill is not available, rails get immured, consoles screwed to the outer wall or protection / lattices can also be combined.
During a storm planting boxes can be swept away, especially if they are old and dried out. Different devices help to prevent this: protection rods which are screwed on the wall and horizontal, protection boards or solid protective grilles are installed.
