• What is the dilution rate? Dilution Rate: is 20ml per 1 litre water. You might want to increase the dilution rate for weeds like Bramble. Read my tips on the relevant pages linked below.
• Will it kill grass? Yes takes about two weeks. When, laying a new lawn it is a good idea to kill all grass and weeds before rotavating it.
• I'm clearing an area of weeds so that I can sow lawn seed. How long do I need to wait between applying glyphosate and sowing the grass seed? Glyphosate is deactivated on contact with soil. It only works by absorption through the green part of plants. Realistically it is better to wait until the weeds are dead. As it may be necessary to retreat some of the more persistent weeds. It is much better to wait and clear the weeds fully, then have to deal with them as the new grass is growing.
• Does it kill Mares tail? Yes and Japanese knotweed, basically it kills all weeds.
• I have a conifer hedge and ivy is rapidly invading it. How would I apply it? Very carefully it will kill the conifer, cut through the ivy stem and treat the root only.
• Will it stain a block paved drive or patio paving? No.
• How long does it take to kill the weeds? The weeds may take slightly longer to show signs of dying off than when you use contact type weed-killers that only kill the upper parts of the weed which come into contact with it. However, these types of weed killers are not nearly as effective as glyphosate at completely killing the weeds. In many instances, weeds treated with a contact weed killer will regrow as the root has not been killed.
