A Heritage Rooted in British Horticulture
SBK Weedkiller sits within the Vitax family of brands — a fourth-generation, family-owned British business with roots reaching back to 1880.

Today, Vitax manufactures in the UK, with sites in Leicestershire and Lancashire, and continues to develop products shaped by professional growing knowledge, retail gardening needs and changing environmental expectations. That long heritage gives SBK Weedkiller a strong foundation — combining traditional horticultural understanding with effective, modern weed control.

What UK Gardeners Say About SBK
Good value. Excellent weed killer for paths, patios etc and "woody" weeds. Be patient, as dead weeds will be evident after 3 or 4 days. Do not use where subsequent planting is planned!
This really works - I was fighting a seemingly losing battle with brambles on the other side of my fence. I now cut them back and spray new growth with this. Also kills thistles. The spray works well and the fact that it is ready mixed means I can keep it in the shed and it is ready to use whenever I see new growth. Although not yet eliminated I do feel I am starting to win.
This took a while to work, but definitely worked on the brambles. They have died, just a shame I can’t get on top of wall to cut them. Also seems to work on ivy.
Perfect weedkiller for killing dock weeds. I was a bit put off by some of the bad reviews on here but then realised a lot of them were expecting results in hours/days. It takes a good 3-4 weeks to have a result. This product essentially causes the weeds to "overgrow" themselves to death, faster than they can physically survive (As seen in progress by the red spots and curling leaves) which at first may seem counter-intuitive but it’s effective for deep roots. If you’re patient enough to wait more than a few days for a result, this is the best and most cost efficient selective weed killer you can get.
I’ve been using this stuff for years and it’s been the best one I’ve used by far. It’s killed brambles in no time, a small tree stump and many other weeds. And with it being a squeeze and pour bottle it makes it so much easier to use without having to need to fill caps or finding other source for measurements. 10/10
It’s quite slow to work but it does the job. I had a hop vine that took over everything and I’m using it on that. Strangely it doesn’t kill grass!
