Garden obelisks are having a major comeback in 2025—think of them as the Beyoncé of backyard upgrades.
These tall, pyramid-shaped plant towers aren’t just pretty—they give your climbing plants a place to show off and make even a small space feel fancy and vertical.
Store-bought ones? Pricey. We’re talking $125 to $200.
But building your own? Around $50–$75, and way more fun.
This DIY project isn’t just budget-friendly—it’s a cool weekend activity that leaves you with something useful and Insta-worthy.
Essential Materials and Tools for Your DIY Project
Before you start building your backyard’s new MVP, make sure you’ve got the right stuff.
Cedar is the fan favorite here—it’s like the Marvel superhero of wood: tough, weather-resistant, and ages like fine wine.
Skip the pine unless you like rot and regret.
Materials:
- 4 cedar posts (2x2s, 8 feet long) – these are your obelisk’s legs
- 16 cedar slats (1x1s, also 8 feet) – these are the cross pieces plants climb on
- Wood screws (2.5” for the big stuff, 1.5” for the slats)
- Wood glue (make sure it’s for outdoor use)
- Optional: wood stain or paint if you want to match your garden’s vibe
- Sandpaper (120 and 220 grit) – for smoothing out those splinters
Tools:
- Circular or miter saw (cue power tool montage)
- Drill + bits
- Measuring tape (don’t eyeball it—you’re not Michelangelo)
- Speed square (keeps everything lined up, no wobbly towers)
- Pencil
- Level
- Clamps (extra hands without needing to bribe your friends)
- Safety glasses + ear protection (because your eyes and ears are important)
Cost: Around $50–$75 depending on lumber prices in your area and whether you go all-in on stain or keep it rustic.

Step-by-Step Construction Guide
Alright, ready to turn those cedar sticks into a climbing-plant throne?
Let’s break it down step-by-step—no woodworking degree required.
Phase 1: Preparing the frame components
Start by chopping your four cedar posts down to 72 inches each if you want a classic 6-foot-tall obelisk.
This is the “model height”—tall enough to show off but not so tall it feels like a cell tower.
Now, grab a pencil and mark spots at 12″, 24″, 36″, and 48″ up each post.
These are where your slats will go, like plant parking spots.
Pro tip: Make your cuts straight. Wobbly angles = wonky obelisk. No one wants a Leaning Tower of Tomato.
Phase 2: Creating the horizontal slats
These slats give your obelisk that cool tapered look—kind of like it’s wearing a tailored suit.
Here’s your cutting cheat sheet:
- Bottom tier: 4 slats @ 27″
- Second tier: 4 slats @ 21″
- Third tier: 4 slats @ 14″
- Top tier: 4 slats @ 8″
Measure twice, cut once. This isn’t Minecraft—mistakes aren’t fixed with an undo button.
Phase 3: Assembly process
Lay two posts down side by side on a flat surface. Line them up so the bottom slat spacing is 27″ apart and the top is 8″ apart.
You’re building one side of a triangle—think Toblerone but for vines.
Start at the bottom and attach the slats with wood glue and screws.
Pre-drill the holes unless you enjoy hearing your wood crack like it just stubbed its toe.
Repeat for the other side, then connect the two with the rest of your slats.
Use clamps to hold it all in place while it dries—kind of like giving your project a big supportive hug.
Phase 4: Finishing touches
Once it’s all together, grab some sandpaper and give it a good once-over—start with 120 grit to knock down splinters, then finish with 220 so it’s smooth enough to hug (not that you’ll need to, but hey, you might).
You’ve got three finish options:
- Let it go au naturel – cedar weathers into a cool silver look.
- Stain it – keeps that warm wood vibe locked in.
- Paint it – go bold. Want a Barbie pink obelisk? Do it. Your plants won’t judge.
Placement and Installation Strategies
You’ve built the obelisk—now let’s talk location. Think of this like placing a throne.
Your climbing plants are royalty. You don’t want them hidden in a shady corner behind the compost bin.
Sunlight is everything
Before you drop it in the ground, check the sunlight.
Most flowering climbers (like sweet peas or morning glories) want full sun—6 to 8 hours of that golden goodness.
Got leafy climbers like ivy? They’re more chill and okay with some shade.
Give it breathing room
Plants grow. A lot. So don’t squish your obelisk up against a wall or stuff it into a jungle of shrubs.
Leave space for air to move through and for you to get in there and prune or harvest without needing a machete.
Make it pop
This isn’t just a plant support—it’s a feature.
Place it where it can be seen and admired, like in the center of a garden bed or at the end of a pathway.
Just don’t stick it right in front of your neighbor’s window unless you want passive-aggressive comments.
Stick the landing
To keep your obelisk upright (and not doing the cha-cha when the wind blows), bury the bottom 6–8 inches into the soil.
If you live somewhere breezy or have tough soil (looking at you, clay), upgrade to concrete footings or metal post anchors.
Use a level to make sure it’s standing straight—unless you’re going for “Dr. Seuss chic,” which is valid but hard to pull off.
Best Plants for Your Garden Obelisk
Your obelisk’s job isn’t just to stand there looking cute—it’s a full-on support system.
But not every plant is ready for the climb. Here’s how to pick the right green stars for the show:
Fast and flirty
If you’re just getting started or want instant garden drama, go with annuals.
They grow fast, bloom hard, and peace out at the end of the season like a summer fling.
- Morning glories – Instagram-worthy flowers that climb like pros.
- Sweet peas – Smell amazing, look fancy. Total garden royalty.
- Nasturtiums – Edible, cheerful, and basically the golden retrievers of the flower world.
These are lightweight, so your obelisk won’t feel like it’s carrying a toddler on its shoulders all summer.
Long-term lovers
Ready for commitment? Go for perennial climbers. These guys come back year after year, so your obelisk becomes more like a long-term garden landmark.
- Clematis – Choose varieties that bloom at different times and you’ll get color from spring to fall. It’s like scheduling guest stars for every season.
- Climbing roses – Dramatic. Beautiful. Slightly high-maintenance, but worth it.
- Honeysuckle – Smells like nostalgia and summer nights.
Heads-up: these need sturdier support, so make sure your obelisk is built like a tiny Eiffel Tower, not a Jenga tower.
Snack time
Your obelisk can do double duty—pretty and productive. Grow stuff you can actually eat:
- Pole beans – Fast growers. Harvest all summer like a veggie vending machine.
- Peas – Cute tendrils, sweet pods, spring vibes.
- Mini cucumbers – Keep it light—your obelisk isn’t a gym rack.
- Cherry tomatoes – Totally doable with extra ties and support. Just don’t let them get wild.
Maintenance and Seasonal Care
You built it, the plants love it, and your neighbors are low-key jealous.
Now let’s make sure your obelisk keeps crushing it year after year.
Spring check
Once the weather warms up, give your obelisk a quick check-up:
- Tighten any loose screws before it starts doing the wobbly dance.
- Look for cracked wood or bug damage—if a post is looking sketchy, swap it out now before things get messy mid-season.
- If you used a wood finish, plan to recoat it every 2–3 years, especially if your climate is more “Game of Thrones winter” than “chill spring.”
Annual clean-up
Before planting anything new, clear out last year’s dead vines, leaves, and whatever that weird fuzz was.
Leaving old plant debris is basically inviting pests to move in and throw a mold party.
Train those vines like a garden coach
Plants don’t always know where to go—help them out:
- Use soft ties or fabric strips (skip the zip ties unless you’re training tomatoes for battle).
- Gently guide new shoots onto the frame before they go rogue.
- Snip off dead or funky growth regularly so your plant doesn’t turn into a tangled mess.
Troubleshooting Common Issues
Even if you built your garden obelisk like a pro, stuff happens.
Here’s how to handle the most common hiccups before your structure turns into garden chaos.
Wobbly obelisk syndrome
If it’s rocking in the wind like it’s at a music festival, the legs probably aren’t anchored deep enough—or the ground’s uneven.
Fix it:
- Make sure all four legs are planted at least 6–8 inches deep.
- Use a level (not your eyeballs) to keep things straight.
- Still shaky? Add some diagonal braces—think of them as yoga blocks for balance.
Climbers refusing to climb?
Some plants are like toddlers—they need a little encouragement to go the right way.
Fix it:
- Make sure there are enough places for vines to grab. Add more slats or even a bit of twine if needed.
- Gently tie the first few stems in place—kind of like showing them the stairway to vine heaven.
- Bonus: Some climbers just need time to get going. Patience, garden Jedi.
Weather drama
High winds? Heavy snow? Your obelisk could take a hit.
Fix it:
- Add diagonal supports if storms are frequent visitors.
- In snowy areas, remove the top tier before winter to avoid a sad, snapped structure.
- Think of it like taking down patio umbrellas before a storm—it saves you a spring repair job.
Enhancing Your Obelisk Design
The classic obelisk is already a garden icon—but why stop there when you can give it some personality?
Here’s how to add extra flair and make it look like it came from a designer garden
Top it off with style
Add a finial to the top—think of it as the cherry on your garden sundae.
- Try a wooden ball, metal ornament, or anything that says “I’ve got flair.”
- Bonus points if it matches your garden vibe—rustic, cottagecore, or low-key Bridgerton.
Light it up
Don’t let your obelisk disappear after dark.
- Wrap it with LED string lights or tuck solar lights at the base.
- Instant evening glow-up. It’s giving “secret garden meets backyard fairy party.”
Choose your aesthetic
Want that weathered, outdoorsy look?
- Use reclaimed wood or let cedar go au naturel. It’ll age into a silvery “I’ve-seen-some-seasons” kind of cool.
Going for a polished vibe?
- Sand it smooth, use clean cuts, and paint it in a color that says “I belong in a magazine spread.” White, black, deep green—go bold.
