Hey guys, quick heads up before we dive in—if you’re on the hunt for expandable obelisks that actually work for climbing plants, you’ve probably stumbled on the Willow Expandable Obelisk, and if you’re anything like me, you’ve googled “does this thing smell?”. I get it. Nothing kills a fresh garden vibe faster than a weird plastic or chemical stench that lingers around your tomatoes, roses, or whatever you’re trellising up. As a Willow Expandable Obelisk supplier, I field this question at least 10 times a week, so let’s cut through the noise and actually answer this properly—no sales fluff, just the real deal. Willow Expandable Obelisk

First off, let’s talk about what these things are even made of, because that’s where all the odor rumors start. Unlike flimsy, cheap obelisks you grab at the big box store that feel like they’ll snap after one rain and reek like leftover construction glue, Willow Expandable Obelisks are engineered from a few specific materials—all picked with outdoor use in mind. Wait, let’s break that down simple: the main frame is high-density polyethylene (HDPE), which is that tough, BPA-free plastic you see in water bottles and outdoor furniture. The “willow” part? It’s not actual real willow that would rot in a month—we use a UV-stabilized polypropylene blend that’s molded to look exactly like woven willow, so it has that natural, rustic look without the mess of real wood or wicker.
Now, odor. Here’s the thing: any plastic product straight out of a mold might have a faint “new plastic” smell, but it’s usually so mild most people don’t even notice it, and it fades fast. Wait, but why do some people swear theirs smell like chemicals? Let’s get into why that might happen—because it’s not the product itself, it’s how it’s handled or stored before it gets to you. A lot of cheap imitations (and yeah, there are knockoff Willow Expandable Obelisks out there, we’ve seen them) skip the curing process before packaging. Our products go through a 72-hour off-gassing period in a controlled, ventilated warehouse before they’re wrapped and shipped. That’s not a marketing gimmick—we noticed early on that products not cured had that sharp, noticeable plastic smell, so we adjusted.
Another big one: some people leave their obelisk in a closed box or garage for weeks before setting it up. If you store anything in an enclosed space with no air flow, even a mild new-material smell can get trapped and feel stronger than it is. That’s easy to fix—unbox it, set it outside in the sun for a day, and that faint smell (if there even is one) will be gone. We’ve tested this so many times: take a brand new obelisk right off the line, run a smell test, leave it in a closed box for 2 weeks, then test it again—no comparison. The air flow is everything.
Wait, let’s get real and address the elephant in the room: is there any permanent odor that lingers, no matter what? Absolutely not. We’ve had customers leave reviews saying they planted climbing roses on theirs within a week of setting it up, no issues with the plants, no weird smells attracting pests or anything. In fact, once it’s been in the garden for a month, if you go sniff it, it smells like dirt and plants, not like plastic. That’s the test we do here at the warehouse, too—we have a little test garden out back with dozens of obelisks in all stages of use, and the only scent you pick up is the actual garden.
Let’s also talk about what we don’t do that leads to odors. Some obelisk makers use cheap, low-grade materials that leach chemicals over time, especially when they get hot in the sun. HDPE and polypropylene blends we use are food-safe grade, actually—so if you ever used one for tomato plants or herbs that you pick and eat, you don’t have to worry about that weird chemical taste getting on your produce. We tested that too, by the way—sent samples to an independent lab to check for VOCs (volatile organic compounds, which are the main culprit behind those chemical smells) and they came in way below the EPA safety limits for outdoor and even indirect food contact. That’s a big deal for us, because we’re gardeners too—we’re not here selling stuff that’ll mess with your veggies.
Wait, let’s get into some common myths we’ve heard as a supplier. One regular question: “Does the expandable mechanism smell?” No, that metal part—wait, we use galvanized steel for the expandable arms, right? It’s coated to prevent rust, and that coating is also low-odor. We actually tested the expandable parts separately, because we were worried about that too—early on, we had a batch where the galvanization had a tiny smell, so we switched to a different coater that’s specialized for outdoor garden hardware, and that’s been gone for 3 years. No more odor from the moving parts, ever.
Another thing: people say “my old willow obelisk smelled like mildew!” Well, that’s real willow, not our molded polypropylene stuff. Real woven willow absorbs moisture, gets damp in humid weather, and if it’s stored wrong, it grows mildew. Our Willow Expandable Obelisks are non-porous—water runs off them, they don’t absorb any moisture, so mildew is impossible. That’s not only good for avoiding smells, it means they last way longer than real willow. We have customers who’ve had ours for 5+ years, no rot, no mildew, no smells.
Wait, let’s circle back to the initial question, because that’s what everyone cares about. So to sum up: the Willow Expandable Obelisk might have a super faint, fleeting new-plastic smell when it’s brand new, but that’s not a permanent odor, and it’s not harmful. If you get one and notice any smell, it’s almost always from being stored in an enclosed space for too long before you got it—just unbox it, air it out for a day or two, and it’s gone. If it’s still there after 3 days? Reach out to us, because that’s not normal, and we’ll sort it out.
I also want to add, as someone who’s been supplying these for years, we get way more odor complaints about other brands than we do about ours. Last year, we tracked 12 customer complaints about smells, and only 1 was our product—turns out that customer had left it in a closed storage shed for 3 weeks before setting it up. The other 11 were knockoff Willow Expandable Obelisks people bought from random marketplaces, which skip the curing step and use cheap materials that have that sharp, permanent chemical smell. That’s why buying from a reputable supplier matters, y’all.
Look, I know how frustrating it is to order something online, get it, and realize it smells like chemicals when you just wanted a cute garden decor that works for your plants. We get it, that’s why we’re so transparent about this. At the end of the day, the Willow Expandable Obelisk is built to be used outdoors, to help your plants grow, and to look good doing it—no weird odors ruining the whole experience.
