Like most garden chemicals, this product is expensive, but as a concentrate goes a long way and is worth the cost. I used a spreader bar bought on eBay to fit on a two gallon watering can. I also made up a strong solution to use in a spray bottle to treat weeds individually later that missed the initial watering can treatment. You see an effect after about a week to ten days. The weeds turn pink / red and eventually go black and dessicated and then slowly vanish. The following season there was a major reduction in weeds in the lawn requiring just spot treatment with the spray.

I have used Verdone over many years with good results, but have found that weeds must be getting more immune to its efficacy. Weedol/Verdone certainly appears to start the process of killing dandelions, but half way through the process the plant appears to recover and bloom again! the instructions call for a once-a-year use, but this is definitely not going to remove the dandelions in my lawn! I shall try a second dose at a stronger concentration and see what happens. It's expensive, particularly if not fully effective.

I have used this before and in my opinion you can not get better, it has killed all the different types of weeds in my lawn leaving it looking great, I only treat it once a year, usually late Spring and that's it for another year, GREAT BUY!

Good all round weed killer on infested lawns/grass. I tend to mix it with another selective industrial weedkiller to cover more weed types. One litre can last a long time, even if you have a large garden.

I first used this last year on my lawn and not one dandelion came through this year. Use this on your driveway, gravel or block paving. Don't buy the watered down stuff as it's too expensive, get the concentrate and mix your own way and lasts longer.
