Planting tips for window boxes

For an effective window box, avoid planting just one type of plant in a single row. Unless you're going for that regimented look. Try to aim for more shape in the design by using a mixture of plants in a zig zag pattern, varying in size, colour and texture.  But, remember colours should compliment or contrast - not dazzle. So don't forget to look at the colour wheel before selecting and also consider the other colour and textures around your window boxes i.e. doors and window frames.

Go for a layered design; use the tallest plants in the back, with the shorter and bushy plants along the middle rows. The front of the flower box should be planted with trailers to give your box that overflowing effect.  

Generally, there are no hard and fast rules with window boxes in terms of the containers you use or the plants you pick.

For best results, pick containers that will blend or contrast with the colours of their surroundings, i.e. the colours of your house, garage, porch, patio or terrace, and other nearby structural and decorative elements. Though the containers can be of any style in any material that you prefer, it is often best to choose a style and material that reflects the style of your home and materials used on your property.

With regards to plants if it can fit into your container then potentially you can plant it. But try and avoid plants with large root-balls as they tend to be evasive. Also, consider the location. Are you boxes in full sun or a dry environment? You need to select plants that are best suited to the location of you box.

Just remember that;

a) all outside containers must have drainage holes in the bottom of the container

b) if you live in a cold winter climate, terra-cotta and ceramic planters must be emptied or moved into a frost-free area for the winter months

c) use plastic or lightweight resin containers if you are gardening on a terrace or roof area where there are weight limitations.

d) make sure you raise the pot/container a inch or two off the ground so drainage can occur without obstruction.
