Create Your Own Garden Planter Boxes at Home

November 8, 2025

Wood planters make an attractive and practical addition to your garden, and building your own is simple with cedar, an attractive yet long-lasting material for growing flowers or vegetables. Learn how to build one yourself now.

Silva begins by clamping one of the long side pieces to a 4×4 support piece and fastening it with exterior screws.

How to Assemble

Once all the pieces have been cut, begin assembling the planter box on a flat surface. Begin by creating long side pieces. Clamp one of these to one of the support pieces, using 3-1/2” exterior wood screws to secure it firmly – this will prevent bowing out when filled with soil! Next add small sides using pocket screws which hide screw heads for an uninterrupted finish.

Preparation

Planter boxes make an excellent addition to any garden – from small balconies to sprawling backyards – offering designated planting spaces for flowers, vegetables, herbs, and shrubs as well as providing structure and organization to any landscape.

Your choice of planter depends on your desired look and maintenance needs for your garden. For instance, if you prefer rustic aesthetics made of wood or concrete, these materials make up easy maintenance while fitting perfectly into the surrounding garden environment. Meanwhile, for contemporary styles that complement home exterior designs nicely consider modern planters made of durable fiberstone or steel materials – either material can provide long lasting beauty.

One thing to keep in mind when selecting your planter box is the depth. Make sure it can support the roots of any plants you plan on growing; tomatoes do particularly well due to their compact nature and smaller root system; other edible crops suited for planter boxes include herbs such as basil, thyme and oregano.

Your planter is also an ideal place for cultivating ornamental flowers and ferns that will enhance curb appeal while adding color and life to concrete areas, like your patio or driveway.

Assembling

Garden planter boxes add beauty, structure, and definition to outdoor spaces. From small balconies to larger gardens and revitalizing concrete landscapes – garden containers come in a range of styles and materials for effortless designs that cater to each unique space.

Assemble these garden planters by clamping one of the 4×4 support pieces inside one long side piece and screwing in pocket screws for each of the slats. When one side is complete, add another until both long sides have been finished – any gaps should be filled with wood glue to ensure tight connections.

Once your sides are constructed, it’s time to install the top frame pieces – we used 4x4s but feel free to experiment with 2x4s or other wood types that suit you! With your frames in place and plants installed inside, the final step will be installing your plants!

Garden planter boxes provide an effective solution for those living in small spaces, enabling you to cultivate herbs, vegetables, flowers, and shrubs without taking up floor space. To get the most out of your garden planter box choose its location carefully to receive ample sunlight so your chosen plants are nurtured well by it and water wisely to reduce evaporation before regularly replenishing soil with fertilizer or compost to increase nutrients levels in your soil.

Finishing

Planter boxes add an attractive accent to any garden design. Paired with careful planting selection and strategic placement, these decorative elements can enhance curb appeal more than any other addition in the yard.

To make your planter truly stand out, select an eye-catching yet durable material such as concrete, weathering steel, timber or plastic. Linings may help prevent soil from escaping while improving drainage; make sure there are drainage holes at the bottom of the box to avoid stagnant water that could harm plants or attract pests.

If you’re creating a raised planter, make sure it is secured to the ground so it doesn’t tip over. For easy assembly, we suggest pocket screws; they make assembly simple while hiding any screw heads for an elegant and professional finish. Furthermore, using a tool called a pocket hole jig makes aligning and drilling holes simple!

Planter boxes can make any yard more visually appealing, especially those with poor soil or built up surfaces like rock landscaping. Elevated garden planter boxes also help manage sloped yards by keeping soil in place and providing proper water retention. Elevated boxes also reduce back strain when gardening so you can grow a variety of herbs, flowers, and vegetables more effortlessly than before.
