My experiences echo a lot that has been written here. If you are reading this then you already know the horror that is horsetail. Was it Alan Titchmarsh who was once asked "what do you do if you have horsetail in the garden?", and he answered "move". From having no trace a couple of years back we have been overwhelmed by this pest (the horsetail, not Alan Titchmarsh) and have tried everything: digging it out (yes, yes, I know now), pulling the stalks frequently to try and weaken it, using proprietory strong weedkillers. And if you're reading this for advice then you know that none give more than temporary respite. So I heard about Kurtail. I read the reviews, balked at the price, but thought I'd give it a go anyway. The first thing to say is that although it is expensive per bottle, it dilutes a long long way, so per application it's pretty reasonable. Within days you could see the weed dying, and fairly quickly there were large swathes of dead horsetail. I've had nothing else that comes near. I'm not naive. I know the battle has only just started but this is the first Big Push that is showing results. I know we will still have to spray and spray as remaining little varmints poke their heads up, but we're winning I feel. For the first time I feel optimistic. Give it a go. Either that or move.
