Tips on Creating A Window Box

Do you have little in the way of outside space but still want to inject some colour outside your house? Or perhaps you just want to add some extra finishing touches to your garden. A window box could be the perfect solution. Read this guide on how to get the most out of yours.

Group Plants According to their Requirements

There’s little point in placing plants next to each other if their needs are completely different. It would make your maintenance of the window box much simpler if plants and flowers were grouped in relation to their requirements of light and water. It would be difficult to ensure your window boxes look their best if some plants are suffering because they require more or less water and light than others. It’s also worth considering a plant’s preference of pH; this is often forgotten when it comes to planting but can make a huge difference to their growth of your plants.

Group Plants According to Growth Habits

You plant a window box in order that you will be able to see and appreciate all plants in it. It would be a shame to miss out on the beauty of one simply because it has become swamped and dwarfed by another, faster and wider growing plant. You may also want to consider time of flowering when arranging your window box. It would be nice to have at least one flowering plant during each month of the year to prolong the beauty of your window box, so research flowering seasons when selecting your plants.

Select the Correct Sized Box

Inevitably, a larger box means that you will be able to accommodate more of your favourite flowers. Larger boxes are also good for plant growth as they have more space to allow for root growth and will avoid looking overcrowded. However, it is important to remember that a larger box with more plants will be heavier and will therefore require stronger fixtures and anchoring and should only be chosen if these provisions are available.

Ensure There’s Good Drainage

Small holes in the bottom of containers mean that water can drain through the soil and will prevent it from becoming waterlogged. Holes will also allow aeration of the soil which will increase oxygen levels in the soil, encouraging superior root growth.

Line Your Container

Most solid plastic containers won’t need lining, as they will be sturdy enough themselves. However, if you have chosen a basket-type container, or one with numerous holes, you should line it with a plastic lining before putting in your plants and soil. This will prevent soil and necessary water from dripping through the bottom and will ensure your plants grow to their maximum potential. N.B. ensure to make small holes in this lining to allow aeration of soil and draining.
