I came up with the easiest EVER address number planter box you can add to the front of your house if you’re looking to add a touch of charm and practicality to the exterior of your home.

DIY-ing a simple address planter box is a fantastic project that’s not only beginner-friendly, it’s sure to add some curb appeal….and you only need 3 things!

I had a big blank space to the side of my door that needed something functional that added texture and interest. I decided to transform a plastic planter box into a wall-mounted address planter with just 2 materials, a drill. and some creativity.

In this step-by-step tutorial, I’ll guide you through the process of creating my unique (and SO SIMPLE) diy planter with some address numbers. This project can easily be customized to your style depending on the planter and house numbers you choose so you can showcase your creativity. Let’s get started!

WHAT YOU’LL NEED

Step 1: Planning and preparation

Start by selecting a suitable location on your house exterior where you want to mount the metal French cleat planter. Ensure the surface is clean and free from any obstructions. 

I decided to mount the planter next to my door under my porch light, but you could add this anywhere — even under a window or on a porch post.

You can also measure the dimensions of your planter box and decide how you want to position the address numbers. Take note of these measurements for later steps. 

Step 2: Attaching the French cleat hanger

Hold the wall side of the metal French cleat hanger against the wall, ensuring it is level and centered within the area you want to hang your planter. The french cleat hanger I used comes with a little level you can insert into the hanger to level it out while mounting.

If you’re working with metal siding or siding that is a hard material, you may want to drill pillow holes for the screws. To do this, mark the screw hole locations on the wall using a pencil or marker. Drill pilot holes at these marked spots to make screwing easier and prevent the wall from splitting.

Next, you’ll attach the French cleat hanger securely to the wall using screws and a screwdriver or drill. My siding is faux stone with a backer board so I didn’t drill pillow holes and just drove the included screws directly in.

If moisture is a concern, you can seal around the holes where you drove the screws with an exterior silicone based sealant. 

Step 3: Attaching the cleat hanger to the planter box

Next you’ll need to mount the other side of the french cleat hanger to the back of your planter. 

First, choose a flat side of your planter to be the back. The back of my planter was actually cracked (so I got it for 50% off at Lowes because it was broken..YAY!) so I chose this as the back.

Line the other side of the french cleat up on the back of the planter and drive a screw through the middle to secure it. Then using a level or eyeballing it, make sure the cleat is level and drive the remaining screws through the planter to secure.

Make sure not to over tighten the screws so that the plastic doesn’t strip — twisting the screw too much with the drill can create a larger hole and cause the screw to be loose.

It should look something like this when you’re finished attaching it:

Step 4: Mounting the planter box

Position the plastic planter box on the metal French cleat hanger, aligning it with the cleat’s counterpart.

Slide the planter onto the hanger, allowing it to lock securely in place. Ensure the planter is level and adjust if needed.

Step 5: Installing the address numbers

Determine the desired placement of the address numbers on the planter box. Mark the locations using a pencil or marker, ensuring they are evenly spaced and level. 

I decided to mount my numbers off-centered so that I could have a trailing plant on one side of the planter box. I added mine to the right towards the door.

Depending on the style of your address numbers, either attach them using screws or adhesive suitable for the material of the planter box. If you don’t want visible screws, you can select some address numbers with a clean front and hidden screws.

Follow the manufacturer’s instructions for proper installation — some address numbers sit flush and others have a spaced back that allow them to set off the surface slightly. I would avoid using any address numbers that require an anchor on the plastic planter since it might not be thick enough to hold it.

Step 6: Finishing touches

Double-check the levelness of the planter box and address numbers. Make any necessary adjustments before tightening all screws securely. 

Step back and inspect your mounted planter, ensuring everything is sturdy and aesthetically pleasing.

Step 7: Planting and maintenance

Fill the planter box with your preferred plants or flowers, taking care to select those suitable for the sunlight exposure in the chosen location. Follow the recommended planting and maintenance guidelines for your specific plants to ensure their healthy growth and longevity. Regularly water and care for the plants to keep your French cleat planter looking vibrant.

I chose to keep my plants in their nursery pots so I could easily take them out individually to water / prune them, but you can plant them fully into the planter box since the box can be removed easily for watering by simply sliding the french cleat off and back on. 

Ta-da! That’s how easy it is to create a stunning address number planter that showcases your style and adds some visual appeal to your home’s exterior. 

This project not only provides a functional planting space but also serves as an eye-catching focal point.
