Window Box

If you’ve decided to freshen up the exterior of your home with window boxes, you should know the basics of window box gardening. One of the main ideas is that window boxes must match up with the length and depth of the window sill. The window planters shouldn’t be in the way of the window itself. The perfect window box is neither too deep or too shallow. The perfect depth of a window planter should be 18cm in order to provide space for plant growth. It should also have proper drainage holes.

When it comes to the types of window boxes, there’s a wide variety to choose from. You have to know what are the most common types of window planters and choose the ones that are suitable for your window box gardening plans.

Plastic Window Boxes

The cheapest window boxes are the ones made of plastic. They are light, rot-proof and seem like a good option. However, they break easily and the plastic becomes brittle after the long exposure to sunlight. If you decide to go with plastic window planters, keep in mind that they can distort and be difficult to handle when you fill them with soil. On the other hand, both plastic and fiberglass window boxes retain moisture levels better than wooden planters and often come with their own drip trays.

Wooden Window Boxes

You can’t go wrong with wooden window boxes. They suit every type of house and are a perfect addition to any exterior design. However, you should stay away from softwood window planters as they tend to rot too quickly. Try to find and buy ones made of elm, oak, ash or teak. These will last for many years without too much care and won’t require preservative paint.

If you can’t find wooden planters that suit your taste, you can always make your own. The ideal material is hardwood, of course. You should make sure that the proportions are right and that the box is deep enough. If that seems like a tough task, you can always go for bespoke window boxes. This will save you a lot of work and you will have window boxes that can’t be found at the local gardening center.

Terracotta and Stone Window Boxes

You can also find terracotta window boxes or ones made from reconstructed stone. They might seem pretty, but they aren’t suitable for window sills as they are heavy and often crack because of frost. They are more suitable for patios and gardens. If you decide to use them for window box gardening, you should make sure they are properly attached to their support.

Window Box Tips

Whatever type of window boxes you decide to use, make sure they are fastened securely. The planter should be on the same level as the window sill. It’s important to back up the window boxes with brackets or chains. It’s even better if the brackets are made from iron.

If you live in an apartment and plan to install window boxes on your balcony, keep in mind that they will hang on the street. This means that passers-by might get drenched when you water your window box plants.

Sometimes it’s impossible to install window planters alone, so you should rely on the help of professionals. The facade of your house might suffer a lot of damages if the window boxes aren’t properly installed. If your windows are too small for window planters, you can try a row of flowering plants in pots. This way you will imitate pretty window boxes. Another option is to try hanging baskets with flowers on the lighter side of the window frame.
