“I know I don’t want to use Roundup anymore… but what’s the next best thing?”
We hear it all the time.
It’s a question that comes up again and again from people looking for safer, effective alternatives.
Most of us aren’t out here memorising herbicide chemistry or debating plant physiology — we just want something that works, doesn’t stick around in the soil for months, and won’t leave us worrying about what the kids, pets, or local wildlife are getting into.
That’s why we’ve been building this running series on glyphosate-free weedkillers — so you can compare your options and decide what makes sense for your garden, school, council grounds, or business.
Today, we’re taking a look at WeedX, made by Goulter’s Vinegar Products right here in New Zealand. It’s a vinegar- and citric acid-based weedkiller, available in both standard and certified organic formulas. On paper, it promises quick results without the toxic baggage — so let’s break down what’s inside, how it works, and where it might (and might not) fit into your weed-control toolkit.
Two Main Options
1. WeedX Natural Weed Control
This is the standard version — still glyphosate-free, still based on acetic (vinegar) and citric acids, but without the added cost of organic certification. You can buy it ready-to-spray or as a concentrate for larger areas. The concentrate is handy if you’ve got a big job ahead, as it’s more economical per litre.
2. Organic WeedX Vinegar Weed Control
Same core ingredients, but certified organic. If you’re using it in a veggie patch, organic farm, or any environment where certification matters (or just gives you peace of mind), this one ticks that box.
Both are non-systemic herbicides — which means they work by burning off the foliage rather than being absorbed and killing the plant from the inside. Translation: great for quick, visible results on young or small weeds, but less effective if you’re trying to eliminate deep-rooted perennials in one hit.
How It Works
WeedX combines acetic acid (vinegar) and citric acid (found naturally in citrus fruits) to break down plant cell walls. Under the right conditions — warm, sunny weather — you’ll often see weeds start to wilt within hours.
Because it works on contact, coverage is key. Miss a leaf, and the plant may recover. For stubborn weeds, you might need a follow-up spray.
The upside? It doesn’t hang around. WeedX breaks down quickly, with the soil pH returning to normal within about 24 hours. It’s safe around mature tree bark, doesn’t harm soil life, and is fine for kids and pets once dry.
When It’s a Good Fit
- Paths, driveways, and edges where you want quick results and don’t mind reapplying as needed
- Veggie beds before planting (especially the organic version)
- Schools, playgrounds, and public areas where safety is a priority
- Gardeners looking to cut down on chemical exposure without losing the convenience of a spray
Things to Keep in Mind
- Works best on sunny, warm days — less effective in cold, wet weather
- Non-systemic, so it won’t stop deep-rooted weeds from resprouting
- Needs good coverage to be effective
- Strong vinegar smell at first (some like it, some don’t — but it’s a lot better than chemical fumes)
New Zealand-made
WeedX is made by a family-run business in Nelson that’s been producing vinegar products for decades. That means you’re not only avoiding glyphosate — you’re also supporting a local manufacturer with a clear focus on sustainable, biodegradable products.
Final Thought
If you’re ready to ditch glyphosate and want something New Zealand-made, fast-acting, and safe for people, pets, and pollinators, WeedX could be worth a trial run. Like all non-systemic herbicides, it’s not a one-spray-fixes-everything solution — but as part of a glyphosate-free weed control toolkit, it can pull its weight.
