This window box is filled with easy-to-grow annuals that will tolerate a sunny position and bloom with a riot of color throughout the summer and into fall. Plant after the weather is settled and there is no danger of frost; the nasturtiums may be sown two to three weeks earlier. Select healthy, stocky plants and pinch off youngest growth to encourage bushiness.

The box can be made of wood, heavy-duty plastic, fiberglass, metal, or any other suitable material. The dimensions are 36 inches long by 9 inches wide by 9 inches deep. It is important that the container provides good drainage, so the plants do not become waterlogged. Make sure there are sufficient holes in the bottom; to avoid losing soil through the holes, cover them with a piece of hardware cloth or screening. The soil mix should be light in weight; we recommend using a commercial sterilized soilless potting mix. Weight is always a problem; fasten your window box securely to avoid accidents involving pedestrians below. Do not allow the soil to dry out excessively; feed with half-strength liquid fertilizer every two to three weeks.
