Learn how to install decorative cedar caps on your raised garden bed posts for a polished look. Step-by-step instructions, tips, and common mistakes to avoid.
Quick Answer
To cap a cedar raised garden bed, simply align the decorative cap on top of each post and secure it with the included galvanized screw using a screwdriver. This quick upgrade protects the wood and gives your bed a finished look.
Why Add Decorative Caps to Your Raised Bed?
Caps aren't just for looks—they cover the end grain of cedar posts, which is the most vulnerable part of the wood. This helps reduce moisture absorption and slows weathering, extending the life of your bed.
A cap also creates a smooth, finished edge that feels nicer to the touch and looks intentional, especially if you've built a custom bed with tall posts.
Choosing the Right Caps
When selecting caps, check the post size you're capping. The Decorative Premium Cedar Cap 3.5 in x 3.5 in is designed to fit posts of the same width, so measure your post tops before ordering.
Caps come with their own galvanized screw, so you won't need to buy extra hardware. Galvanized screws resist rust, which is important in a garden environment.
Step-by-Step Cap Installation
- Measure and gather supplies: Check that your post tops are 3.5 x 3.5 inches and that you have one cap per post plus a screwdriver. If your posts are a different size, choose caps that match exactly. Don't assume caps fit—measure first.
- Position the cap: Place the cap centered on top of the post, with the decorative side facing up and all edges aligned evenly. Hold it steady with one hand. Make sure the cap sits flush—no overhang on any side.
- Drive the screw: Insert the galvanized screw through the pre-drilled hole in the cap and into the post. Tighten with a screwdriver until the cap feels snug, but avoid over-tightening which can split the cedar. Stop turning as soon as the screw head is flush with the cap surface.
- Repeat and inspect: Cap every post the same way. After installation, run your hand over each cap to confirm it's secure and level. Re-tighten any that feel loose. A quick final check prevents caps from working loose over time.
