Finding your way to someone’s house shouldn’t feel like navigating a maze, right? Yet, there I was, driving around the block a few extra times just to spot their house number. Sound familiar? Well, that’s why we’re taking matters into our own hands with a little DIY project.

It’s a combination of a house number and a planter box, so not only will it show your address, but it will also add a touch of greenery to your entryway. I’ve had my fair share of struggles finding the perfect spot for my house number. But with this nifty project, it’s like killing two birds with one stone – or in this case, planting two seeds with one pot.

Let’s dive into it.

Optional: Add drainage

You know, even though the plan doesn’t mention it, I decided to take a proactive step and drill a hole in the middle of the bottom for drainage. I think it’s a good idea to prevent root rot. If the soil gets too waterlogged, it can cause the roots to rot, and nobody wants that for their plants.

Additionally, adding drainage can also help prevent wood rot by ensuring that excess moisture doesn’t hang around for too long.

Pro Tip: Apply Painter’s Caulking Before You Paint

Protecting the end grain of wood is key. The end grain is like a sponge when it comes to soaking up moisture, which can lead to all sorts of problems down the line.

Just to be extra cautious, I applied painter’s caulking to all the end grain to seal off those corners inside and out. I did this before I broke out the paintbrush, just to add a little extra protection.

Final Thoughts

Now, your DIY house number planter box is ready to take its place by the front door. It’s pretty easy to make, and I’m pretty happy with how it turned out.

It’s a practical project that could also be a statement piece that adds a splash of personality to our homes. And hey, if we manage to keep the plant alive, that will be a bonus!

Anyway, I hope you enjoyed this one.
