Frequently asked questions
What’s special about it?
My double action weedkiller is based on pelargonic acid, a naturally occurring ingredient found in geranium leaves, which when sprayed onto the weeds kills their leaves within hours. There’s an immediate but also long lasting effect as it also includes a very special ingredient which stops the roots from growing, preventing new growth from the treated weed. In trials, the special double action effect means that it is better than weedkillers based on glyphosphate (the key ingredient in the best known weedkillers) as it can be seen to work much faster and gives as good, if not better, long term control of weeds. It’s also environmentally friendly and biodegradable. Once the spray has dried, pets can safely be allowed into the treated area. Unlike many other weedkillers, such as those based on glyphosate, it can also be used in cooler weather so you can apply it anytime from early spring to late autumn. Another advantage is that my double action weedkiller only works on the green parts of plants, not on woody bark so it can be safely applied to weeds growing under the woody stems of hedges, trees and bushes.
What can I use it on?
My double action weedkiller works on a wide range of annual and perennial weeds including horsetail, mares tail nettles, dandelions, thistles, and ground elder, as well as grass, moss and algae. It is most effective on smaller, actively growing weeds . It’s only fair to say that it isn’t that effective on Japanese Knotweed. Sadly, I don’t know of any weedkiller that really does works on this invasive weed.
How do I use it?
Spray on a fine day when the weeds’ leaves are dry. Spray the plants until the leaves are dripping wet. The weeds will be seen to die within hours. With problem weeds such as ground elder and horsetail, you should repeat the application around four to six weeks later. Ground Elder needs to be at least 4in/10cm high before treating so that there is the largest possible leaf surface available for the weedkiller to be absorbed and be most effective.
What area will it treat?
The one litre ready to use spray treats up to 30 sq. metres and the 500ml concentrate (also included in the pack) can be diluted to treat up to 90 sq. metres.
