DIY Planter Box: Build a Water- and Rot-Resistant Planter Box

DIY Planter Box – How to Build a Water- and Rot-Resistant Planter Box

Add a pop of color to your garden or porch with this simple planter box. It takes just a few power tools to make, and it’s made from cedar fence boards, which are water- and rot-resistant.

Before starting, make sure you have all the lumber you need. This includes a detailed materials list with recommended board cut layouts for the most cost-efficient use of your wood.

Materials

A simple planter box can add a fresh look to your garden or balcony. It can even be used to grow herbs or vegetables, depending on what you prefer to eat. It’s easy to build and can be painted in any color you like.

Alternating layers on this planter create a honeycomb effect that looks stylish and modern. Made from cedar, the planter sits on dark feet that keep it off the ground at a comfortable height. The downloadable plans include detailed drawings, 3D visuals, and materials and cut lists that are easy for beginners to follow.

To make a diy planter, start by measuring out three-foot boards. Cut them at the appropriate lengths and mark their ends with a try square to ensure that they fit together properly. It’s best to make all of your cuts at once rather than making them as you go, as it will be faster and more accurate. Drill drainage holes in the bottom of your planter to prevent diseases caused by soggy roots.

Design

Aside from the material used in a planter box, its design can also make or break its appearance. Circular planters look elegant and are an excellent choice for plants with large leaves and flowers or for planting trees. They also contrast well with square and rectangular paving, rills, and walls.

If you want to grow herbs and vegetables in your backyard, consider a raised garden planter with trellis designs. Taught carpenter Jen Woodhouse built one to sit between her windows for added symmetry. It’s a simple project that requires only single wood boards and tools you likely already have in your garage.

This wooden planter from A Beautiful Mess is designed to be placed indoors, although you could certainly use it outdoors as well if you wanted to. It’s an easy-to-follow DIY that can be done in a single afternoon. It uses a few power tools, but only moderate skill is required to finish the project.

Wood

Pine, cedar and teak are good choices for this kind of project as they’re all known for their resistance to moisture. This can be introduced by condensation caused by temperature changes, precipitation such as rain or watering your plants and of course the wood itself.

Choose wood that has been pressure treated as this will be resistant to fungus, general weather conditions and insect activity. If you opt for untreated pine it would be worth investing in a wood preservative to help protect your planter box.

It’s also a good idea to scuff all surfaces of your wooden planter before applying any form of wood treatment as this will create minute pockets and ridges for waterproofing paint or stain to cling to. You could also consider lining your planter if you are growing edible plants such as herbs, lettuce, vegetables and flowers. If this is the case then make sure to line with a waterproof membrane or architectural fabric.

Assembly

Before starting to assemble your planter box, make sure you have all the materials and tools you need. Also, if you have the time, it is worth your while to lay out all of the pieces and cut them at once instead of doing them as you go along. This will be much faster, easier, and more accurate.

Once you have all the pieces cut, it is time to assemble your planter box. Start by attaching the short side slat pieces to the two long frame pieces. You will need to use wood glue and 1 1/4” pocket hole screws for this. Make sure the slats are evenly spaced and that there is a 1/2”’ between each slat.

Next, attach the long brace pieces to the other pair of legs. This will help prevent the angled legs from leaning. Secure these with the same method as the first pair of legs.
