Our Top Picks for the Best Plants for Window Boxes[wptb id="8295" not found ]
What You Need to Know about Container Gardening
You can think of a window box as a mini container garden. It’s an opportunity to mix and match plants to add a dramatic focal point for your balcony or house. And just like your landscaping, it can create a mood. The small space means that you need to choose plants carefully for the best bang for your buck. Even a window box can act as the setting for a beautiful garden.
Your plants will appreciate a sunny location or sunny window. And in the closed space of a window box, it makes sense. While you want your plants to get enough light, you also want to ensure that air circulation and sunlight will allow the container to dry sufficiently between waterings. That’s a risk with any potted plant. You need to balance moisture needs without harming your plants.
Proportions make a difference with window boxes. Its width should match that of the window, give or take a few inches. You should choose a box that is at least six to eight inches in width and depth to give your plants space to grow. As far as the container itself, your options are endless. It should match both the style of your house and the plants it’ll contain.
Setting Up a Window Box
Set up is the same as it is for any other container or basket. The only difference is the container. You do have the added caveat that a window box commands greater attention to one of a group of potted plants. Therefore, you should keep this extra demand that exists for these plants. Take into account how they will complement your house. Color is an essential consideration.
Your choice of container is optional. Soil mixture is another thing. For the best success, you should choose one that will match the needs of your plants. Peat mixtures offer a lightweight solution for meeting the nutritional needs of your plants without putting a lot of stress on the location of your window box. They create well-draining and fertile soil conditions.
The thing you need to remember with window boxes or any container is that moisture is a limiting factor. Too little water will stress your plants unduly and throw a wrench in your landscaping. After all, you want a container filled with lush, thriving plants rather than ones that are struggling for lack of moisture. To keep the soil in the optimal conditions, consider a liner.
Keeping the Moisture In
A liner will keep moisture from draining out of your soil too quickly. It will keep soils moist when sunlight threatens to dry them out. Some good options include sphagnum moss and coconut fiber. Each one will add a decorative element too. Each one is porous enough to let water drain while retaining some water to keep plants healthy.
The routine care of a window box garden is the same as any container. In addition to moisture, you’ll also have to ensure that your plants have enough food. The soil is their only source of nourishment. Slow-release food granules offer an easy option that can reduce the risk of overdoing it with too much fertilizer. Too much is just as bad for your plants as too little.
Another thing to consider is what your plants will attract to your site. Bees, for example, are fine in the garden, but may not be the best choice for a window box. On the other hand, a window box is best enjoyed from outside where you can see the whole picture. Plants with sweet scents can bring its beauty indoors.
Choosing Plants for a Window Box
You can fill your window boxes with a single type of plant. You can also add a few different kinds to create that mini garden. If you have more than one window box, you can also alternate between different plants to create symmetry. As a general rule of thumb, strive to complement the background rather than create a mixed message.

Annual or Perennial?
Depending on your hardiness zone, you can opt for either annuals or perennial plants. The advantages are clear. Annual plants give you the chance to try out different themes. It’s a viable option if you live in a northern climate where plants may struggle to survive. Perennial plants, on the other hand, offer a set-it-and-forget-it option. You are left with just the routine maintenance.
Capturing a Look
There are a couple of other things to consider when choosing plants. You don’t want to obscure your view. Plants with a lower height will prove a better choice. You should also consider layering plants to add more interest. Tall upright plants will make a nice backdrop to cascading vines or ivy. Even in a small space like a window box, you can create a microenvironment.
