Rated 5 out of 5 by from Excellent results I bought this as I have used it before and got excellent results. Much better than the equivalent purchased from garden centres. Turned a neglected patch of scruffy grass into a passable lawn.

Rated 5 out of 5 by from Ok up to now Easy to order and collect as always. Used my Scotts Spreader ok and up to now is making a good job of killing moss and weeds. Lower dosage rate than others and is effect is slower but apparentl.

Rated 1 out of 5 by from Killed some but not all weeds I Followed instructions and I applied weed killer, over a month ago. It has killed some weeds but the majority are still alive. I would not purchase again, disappointing.

Rated 4 out of 5 by from Quite good but doesn't go far Second bag of this. Seems to be as good as any other lawn weedkiller, but since the death of 2-4-D for domestic users, is no good on small leaved weeds. Granular, easy to spread, but one bag can soon disappear on even a smallish lawn. Coming to the conclusion that in the south at least and on the chalk, lawns are a waste of time. Last year's heat and drought finished the lawn off so the weeds came back with a vengeance. Glyphosate round the edges seems to be seeing off the weeds for now.
