What UK Gardeners Say About Gallup
Still the best weedkiller for both leaves and roots. Do wear gloves when using. Bottle makes up to a watering can (depending on size) but seems to work ok on standard patio weeds and grass if using a standard watering can. Need to use stronger if have problem with knot weed.
Always buy this to eliminate my weeds, takes about 3 weeks but completely destroys weeds for at least 3-4 months, I use 1 cap full per liter water and seems to always do the job.
Works really well. I had a new planting border with new top soil which sprouted a jungle of weeds. An area of 29x1m. Use Gallup dipped as per instructions using a 25ml measuring cylinder and wearing gloves. Due to the density of my weeds I mixed up 2l so I can get in amongst all the weeds. Could see it working noticeably within a 2 weeks and by 4 week all the weeds have shrivelled down to the root and super easy to pull up.
Delivery was quick and perfect in time. Thank you for that, as I managed to use it on a sunny day. It is a good product (strong and effective). I have suffered from weeds in the driveway for so long and nothing worked. This product (Gallup weedkiller) has worked well this time, so far. It’s over a month gone and the weeds are under control. The only thing I did not like was the sprayer, which comes with it. That one does not work well.
Best weed killer I know. Works very quickly. Just be careful as it kills everything it touches when used without diluting. Highly recommend.
Gallup weedkiller seems to be getting rid of the clover and weeds that were coming up in my lawn. Acts slowly but seems to be killing them off.
