If you’ve been wanting to build a vertical pallet garden but feel a little intimidated, I promise you it’s way easier than it looks! I built my first one a few years ago with a single pallet I found behind a local furniture store, and it completely changed how I use my backyard space. It’s one of those projects that looks impressive but doesn’t require a ton of skill or money to pull off. Build a Vertical Pallet Garden is a popular choice for gardeners.
The best part? A vertical pallet garden is perfect for Florida gardeners who are short on space but big on plant ambitions. Whether you’re growing herbs, strawberries, or trailing flowers, this setup lets you pack a lot of green into a small footprint.
What You Need to Build a Vertical Pallet Garden
Before you start, you’ll want to grab the right pallet. Look for one stamped with “HT” on the side, which means it was heat-treated rather than chemically treated. You do NOT want a pallet marked “MB” because that stands for methyl bromide, a pesticide you definitely don’t want near your food. The UF/IFAS Extension has great resources on safe container gardening materials if you want to read more about this.
Once you have a safe pallet, here’s what else you’ll need. Grab some landscape fabric or burlap, a staple gun, potting mix, and your plants or seeds. You’ll also want sandpaper to smooth any rough edges, and some wood screws if you plan to mount it on a fence or wall.
The whole materials list will run you maybe $20-30 if you already have basic tools. Finding the pallet for free makes this one of the most budget-friendly garden projects out there. I’ve seen people spend way more on fancy planters that don’t even hold as many plants!

Start by sanding down the pallet so nobody gets a splinter. Then lay it flat on the ground and staple your landscape fabric across the back, the bottom, and the sides. This creates little pockets that hold your soil in place once the pallet is standing upright. Make sure the fabric is pulled tight and stapled really well, because loose fabric means soil falling out everywhere.
Next, fill each slat pocket with a good quality potting mix. I like to use a mix that has some perlite in it for drainage, which is extra important here in Florida where our heat can cause soil to dry out fast. Pack the soil in firmly but not so tight that roots can’t breathe.
Now comes the fun part: planting! Tuck your plants or seedlings into the gaps between the slats. You want to let everything settle for a few days while the pallet is still lying flat before you stand it up. This gives the roots a chance to grab hold of the soil so nothing slides out when you go vertical.
Once your plants look settled, prop the pallet upright against a wall, fence, or sturdy post. Make sure it’s secure so it won’t tip over in a Florida afternoon storm!
Best Plants for Your Vertical Pallet Garden
Choosing the right plants makes a huge difference in how well your vertical pallet garden performs. Shallow-rooted plants are your best friends here. I love planting herbs like basil, parsley, chives, and mint because they grow fast and you can snip them constantly for cooking. Lettuce and spinach also do really well, especially during Florida’s cooler months from October through March.
Strawberries are another fantastic choice because the runners trail beautifully over the slats. Succulents work great too if you want something low-maintenance that can handle the heat. For flowers, try nasturtiums or petunias for a pop of color.
Avoid deep-rooted vegetables like tomatoes or carrots in a pallet garden. They just don’t have enough room to thrive. Stick to plants that are happy with about 6-8 inches of soil depth and you’ll be golden. The Old Farmer’s Almanac has a great planting guide that can help you figure out what grows well in your specific season.
Caring for Your Pallet Garden in Florida’s Heat
Watering is the biggest thing to stay on top of with a pallet garden. Because the soil volume is small and the pallet is exposed on multiple sides, it dries out much faster than a regular garden bed. Here in Florida, during the summer months, I check mine every single day. Stick your finger into the soil, and if it feels dry an inch down, it’s time to water.
I also recommend adding a slow-release fertilizer to your potting mix when you first plant. After that, a liquid fertilizer every two to three weeks keeps things growing strong. Pallet gardens can get nutrient-depleted faster than in-ground gardens because you’re watering so frequently and nutrients wash out.
Placement matters a lot too. Most herbs and vegetables want at least six hours of sun a day. But in the peak of Florida summer, some afternoon shade can actually save your plants from getting scorched. I moved my pallet garden to a spot that gets morning sun and afternoon shade, and my herbs have never been happier.
Watch out for pests like aphids and whiteflies, which are super common in Florida gardens. A simple spray of diluted neem oil every couple of weeks keeps most of them under control without harsh chemicals.
Building a vertical pallet garden is honestly one of the most rewarding weekend projects you can take on as a gardener. You get fresh herbs and veggies, a gorgeous focal point in your yard, and the satisfaction of knowing you built the whole thing yourself.
So go find yourself a good pallet and give it a try! Once you build a vertical pallet garden and see how well it works, you’ll probably want to make two or three more just like I did.
