How to Create a Beautiful Plant Window Box

Creating a beautiful plant window box is a great way to add some greenery to your home and make a statement. Choose a location that gets at least 4-6 hours of direct sunlight per day, as this will ensure your plants thrive.

Select a variety of plants that are suitable for window boxes, such as petunias, geraniums, and succulents. These plants are low maintenance and can tolerate the varying temperatures found in window boxes.

A window box can be as small as 6 inches deep and 12 inches wide, or as large as you like. Consider the size of your window and the style of your home when selecting a window box.

Before you start planting, take some time to design and lay out your window box. This is where the magic happens, and you get to see your vision come to life.

Keep in mind a few basic design principles to get started. Then, unleash your creativity and have fun with it!

To ensure you're happy with the positioning of your plants, lay them out beneath the window box, especially if you'll be planting while standing on a ladder. This is also a great time to give them a really thorough soak if the soil is dry.

Consider mirroring the front and back of the boxes if they're exposed on both sides, like ours. And, for longer boxes, think about spacing several thrillers to create a visually appealing arrangement.

Designing your window boxes is all about creativity, so keep in mind a few basic design principles and then unleash your imagination.

To create a cohesive look, consider using repetition in your planting, like in this 15-foot-long box planted with repeating groups of ivy ball topiary, chartreuse coleus, and white caladium.

Repetition is foolproof for creating a cohesive look, and it's a great way to achieve a sense of flow and order, as seen in this large window box planted with repeating groups of four different plants.

For smaller boxes, use one thriller in the middle, and for longer boxes, consider spacing several thrillers. This will add visual interest and create a sense of depth.

Don't worry about making your design perfect at this stage – you can always move the plants around and adjust the layout once they're planted.

Creative Contrast is a design principle that can elevate your window box game. By combining plants with contrasting colors, shapes, or textures, you can create a visually appealing display that draws the eye.

Contrasting colors can be achieved by pairing plants with different hues, like red-orange copperleaf and variegated sea hibiscus, which create a pleasing contrast with more finely textured Spanish moss and trailing English ivy.

Shapes can also be used to create contrast, such as combining large, colorful leaves with smaller, more delicate foliage.

Incorporating different textures can add depth and interest to your window box, like pairing the silvery leaves of plectranthus with the delicate-looking blooms of the begonia and lantana.

When selecting plants for your window box, it's essential to include a mix of thriller, spiller, and filler plants with the same light requirements. This will ensure a full and colorful display.

Most successful window boxes contain a mix of these three primary plant types. These are some of our favorites in each category.

Thrillers can be plants like bell peppers or scented geraniums, which add height and drama to the window box. These plants are perfect for adding a pop of color and texture.

Spillers, on the other hand, are plants that cascade over the edges of the window box, creating a beautiful display. Examples of spillers include nasturtiums and Johnny-jump-ups.

Fillers are plants that fill in the gaps and add volume to the window box. Pansies and flat-leaf parsley are great examples of fillers.

Perlite can be used to lighten the load of your window box, as it can help reduce the weight of the soil and plants. This is especially useful for larger window boxes.

Edibles with ornamental appeal can be a great choice for a window box, as they do double duty in providing both beauty and a source of fresh produce.

Planting a window box with a cascading effect can add a beautiful touch to your outdoor space. This look is achieved by using a trailing plant that can spill over the edges of the box.

The sweet potato vine is a no-fail choice for this type of planting, as it's a fast grower that adds a lush, cascading look. It's also a great choice because its bright chartreuse leaves take on a gold hue in the sun.

To create a cohesive look, remember to choose plants that have the same light requirements. This means selecting thriller, spiller, and filler plants that all thrive in the same conditions.

In the example of a sweet potato vine window box, the vine is paired with other plants that complement its look. Two sweet potato vines (Ipomoea batatas 'Margarita') are used, along with two snapdragons (Antirrhinum 'Floral Showers Rose Pink'), one pentas (Pentas 'Graffiti Pink'), one snapdragon (Antirrhinum 'Floral Showers Apricot'), and two calibrachoas (Calibrachoa 'Superbells Trailing Rose').

Using Styrofoam in Planters can be a problem. Some types of styrofoam-like packing products are made from cornstarch or other materials and break down easily with water, causing your plants to sink lower in the box over time.

True non-soluble styrofoam might seem like a better option, but it can attract ants. I've had this experience myself, and it's not what you want - especially if you have toddlers around.

Perlite, on the other hand, doesn't seem to be as appealing to ants. It doesn't have the structure or stickiness that styrofoam or plastic-filled dirt has, so ants tend to lose interest.

I've learned the hard way that styrofoam in planters is not worth the hassle. It's better to opt for a more ant-proof and plant-friendly alternative.

First, make sure your window box is secured properly, as this will prevent it from falling or toppling over. This is especially important when adding soil, plants, and water, which will weigh it down.

To add plants, gently remove them from their containers and break up the roots to ensure they can absorb water and nutrients. You can also tip the container on its side and gently tap on each side to help the plant wigggle free.

Before planting, lay out your plants beneath the window box to get a sense of their positioning and to give them a good soak if the soil is dry.

To plant a window box, you'll need to start by laying out your plants beneath the box to ensure you're pleased with the positioning. This is also a great time to give them a thorough soak if the soil is dry.

Gently remove the plants from their containers, breaking up the sides and bottom of the roots as you go. Don't worry if roots break when pulling the plant from the container - it's a normal part of the process.

Add plants to your window box according to your design, leaving enough space for each plant to breathe. I like to tip the spillers to where they will pour out of the window box for a full, flowing look.

Water your plants gently, targeting the base of each individual plant to help the fresh potting mix settle around the roots. This will help prevent any smudges of dirt on the window box.

Add a thin layer of moss or mulch to the top of the plants, which will help keep the soil moist and prevent it from drying out between waterings. Make sure to leave at least one inch of space at the top of the window box to prevent soil from spilling over with each water.

Finally, top the plants with a scoop of soil, using one of the plant containers as a scoop to spread it evenly. Finish with a thin layer of moss or mulch to keep the soil moist.

A self-watering system is basically the best invention ever. It allows your plants to go all day without needing another drink.

The system typically has channels or a reservoir built into the bottom of the box to hold extra water. This feature is perfect for busy people who tend to forget to water their plants.

My favorite self-watering box has this feature, and it's a game-changer. It means I can set up my boxes to automatically get watered, and I don't have to worry about overwatering or underwatering.

The system also has an overflow, which means that once the water in the planter reaches a certain level, it will drain out of the box on its own. This prevents waterlogged soil and root rot.

Window boxes can damage your house if not installed or maintained properly, but using ones with drainage holes on the bottom and mounting them according to the manufacturer's directions can help prevent this.

If you get the right window boxes, they can hold up amazingly well with proper care and attention.

To minimize potential damage, make sure to follow the manufacturer's instructions for mounting and caring for your window boxes.

You can keep your window box looking fresh all season long by rotating plants that thrive in different temperatures.

Pansies are a great choice for cooler weather, but they'll eventually fade after their peak.

Lighting for your plant window box is crucial, and it's essential to note how many hours of sunlight they will receive. For optimal growth, most plants require at least 4-6 hours of direct sunlight per day.

You'll want to determine the location of your window boxes and assess the lighting they'll get throughout the day. Some areas may receive partial shade or full shade, so be sure to observe the light patterns in your space.

In terms of watering, it's best to water your window boxes in the morning, allowing the plants to absorb the water before the heat of the day. This will also give their leaves and flowers a chance to dry out during the day, helping to prevent fungus and diseases.

Watering your window box is a daily task, especially during the hottest summer days. It's essential to water your plants in the morning to give them a chance to fill up and be protected from the sun all day long.

Watering your window box once a day is a good rule of thumb, especially for 3-6 foot boxes. In Utah, one full large watering can every morning is recommended, which can be around 1-2 gallons.

To prevent dried-out skin, use a moisturizer that helps lock in moisture, just like the vinyl in your window box helps keep the wind and sun from drying out your plants.

The key is to create a barrier that prevents moisture loss, and a good moisturizer can do just that.

Every environment is unique, but you'll generally fall into one of three categories: Shade (0-3 hours of sunlight daily), Partial Shade/Partial Sun (3-6 hours of sunlight daily), or Full Sun (6 or more hours of sunlight daily).

Consider the sun exposure in your outdoor space. If you're not already familiar with the plants that will thrive in your environment, read the tags on plants you like and ask a pro at your local garden center if those are good choices.

The amount of sunlight your window boxes receive is crucial. You'll need to determine the location of the window boxes and what lighting they will have throughout the day.

Note how many hours of sunlight your window boxes will receive. For example, one box might get a mixture of partial shade and full shade.

Every hour of sunlight counts, and understanding your lighting conditions will help you choose the right plants.
