Diy window flower boxes

Window boxes provide an outdoor decoration for plant display that blends beauty and practicality. There are two many types of window flower boxes: store-bought and homemade, each with its own advantages and disadvantages. A store-bought window flower box is convenient because it’s already assembled and ready to install. It is available in various styles, sizes, and materials, including wood, plastic, terracotta, or copper. However, a pre-made box can be expensive and does not always fit your window’s exact dimensions or match your home’s aesthetic. On the other hand, building your own DIY window flower box allows for more customization. For instance, you can choose the size, style, and color that best fits your home’s exterior, make the box removable, or install a self-watering system. Building your own box is also a fun and rewarding project for the entire family. On the downside, a DIY window flower box is typically suitable for a single material: wood. It also requires access to power tools like a circular saw unless you order wood boards with the exact measurements you need.

With just a few materials from your local hardware store and a bit of elbow grease, you can craft a unique window flower box in no time. Here is a list of the DIY window flower boxes described in this article:

What is the difference between a window flower box and a planter?

A window flower box and a planter are both used for displaying plants, but there are some key differences between the two. A window flower box is a long, narrow container designed to be mounted on the outside of a window. These boxes are typically made of wood or metal and can be attached to the window sill or hung from brackets. Window flower boxes are often used to add color and charm to the exterior of a home. On the other hand, a planter is a container that can be used indoors or outdoors to display plants. Planters come in a variety of shapes and sizes, from small pots to large troughs. They can be made of materials like clay, ceramic, plastic, or metal.

What are the benefits of a window flower box?

A window flower box has many advantages, both aesthetically and functionally. For example, it enhances curb appeal since a window box adds charm and character to any home. A well-maintained home with beautiful window boxes can increase its value and make it more appealing to potential buyers. Flowers often receive more sunlight than those planted directly in the ground, leading to better growth and overall health. If you have limited outdoor space, window boxes offer a way to enjoy gardening without occupying too much room. Elevated window boxes help keep pests away from your plants and reduce the risk of damage or infestation. You can grow herbs and even small vegetables in your window boxes, providing you with fresh ingredients at arm’s reach for cooking. Additionally, certain herbs are natural repellents for annoying critters, such as basil for flies and mosquitoes.

Do window boxes cause damage?

Yes, window boxes can potentially cause damage if not installed and maintained correctly. Poorly sealed window boxes may leak water or insecticides that seep into your walls and cause long-term structural damage. If a window box is too heavy and placed on an ill-prepared wall, the weight of the soil can put stress on it and eventually lead to a collapse. To prevent any damage, make sure to securely attach a window box to your house with proper fasteners, use quality liners that won’t rot or crack over time, and keep the weight of the filled soil within recommended limits.

Do window boxes add value to your home?

Yes, window boxes can add perceived value to your home and increase its curb appeal, but mostly to help with the presentation for potential buyers.

Should window boxes be bigger or smaller than a window?

Window boxes should typically be slightly bigger than the window so that they don’t look too small or out of proportion. A good rule of thumb is to make the window box about 2 inches wider than the window and no more than 4-5 inches longer for a vertical configuration.

What types of material should I use to make a DIY window box?

The best materials to use when creating a DIY window box are wood, fiberglass, metal, plastic, and vinyl. Wood is the most common material since it is easy to manipulate, provides a natural look, and can be painted or stained to match any aesthetic. Fiberglass is lightweight and durable. Metal window boxes come in various finishes like brass, copper, or stainless steel. Plastic window boxes offer both durability and affordability, while vinyl is an excellent option for an easy-care material that will not rot or rust.

What should I put in the bottom of my window box?

There are several ways to promote window box drainage. For example, drill holes in the bottom, incorporate a layer of landscape fabric, pea gravel or pebbles, install a self-watering system, or place a sprinkler directly underneath your window box.

How do I keep my window boxes from rotting?

To keep window boxes from rotting, use water-resistant materials like treated wood or plastic. Regularly check the plants and remove any dead or decayed foliage as quickly as possible. Additionally, avoid letting the soil become too wet by using a mulch or rock layer over it and draining any excess moisture away from the box.

Is there any regular maintenance necessary for my DIY window box?

Yes, regular maintenance is necessary to ensure your DIY window box stays in optimal condition. For wood, it should be treated periodically with a sealer or preservative to prevent weathering and water damage. Metal boxes should be checked for corrosion and repainted if needed. You should also make sure there are no loose screws or connections that need tightening. It’s a good idea to inspect the window box once every 6-12 months for any signs of damage or deterioration. Additionally, the plants inside should be checked frequently to ensure they’re healthy and have enough water and nutrients.

How many plants should be in a window box?

The number of plants to fit in a window box depends on the size, but typically no more than 5-6 small plants. They must have similar light and water needs to avoid competing for resources.

What are the best plants for window boxes?

The best plants for window boxes are trailing flowers like petunias and ivy, herbs like parsley and rosemary, or shrubs like boxwood and lavender.

What can I use instead of a window box?

There are many window box alternatives, such as wall-mounted planters, raised planters, deck railing planters, and balcony planters.

What’s the difference between window flower boxes and vertical gardens?

Window flower boxes and vertical gardens are both popular options for adding greenery and beauty to small spaces, but they differ in a few key ways. Window flower boxes are typically rectangular containers that are mounted on the outside of a window, filled with soil, and planted with flowers or other plants. They provide an attractive display from both the inside and outside of the building, and can be easily changed out seasonally or as desired. Vertical gardens, on the other hand, are designed to grow plants vertically rather than horizontally. They can take many forms, from simple wall-mounted planters to elaborate living walls made up of multiple layers of plants. Vertical gardens often use hydroponic or other soil-free growing systems to maximize space and create striking visual displays.


Creating a window box is an excellent way to add style and creativity to your home. It’s also an easy and affordable project that anyone, regardless of skill level, can take on. With a few simple materials and the right plants for your climate and conditions, you will craft an eye-catching flower box in no time. Check out more spring decoration ideas.
