Greens your lawn very well

This product is very easy to use and gives good results. I used it to kill moss and to green up the lawn. It will need another treatment in about 3 months time as it doesn't contain nitrogen which helps make the grass grow. But I'm pleased with how it has worked.

I've tried to use those feed/weed/moss killer granules to kill lawn moss but they were useless. The moss just laughs at granules. So went for the liquid version to water in using a watering can. This certainly is more work but its not that big a deal. There is enough to treat a large lawn using the max dose. It will kill the moss in hours and it turns brown - but it does need to be raked out for max benefit which may leave bare patches behind. I found using a lower dose manages the moss, still kills it, but makes less work in raking it out. The moss will eventually return but there is enough tonic left to keep the moss down for a few months using a weaker mixture. So Man-1, Moss-0. Result.

Various mixing levels for different jobs. Works really well

I’ve used this a few times now at strengths from 250 a 300 ml/l and not seen the green-up effect I had hoped for. Will try again and hit it with a dose 500ml+ to see if it makes much difference. Don’t spill any on pavers or overspray as it will cause rust stains!

Ok, listen, this will find every bit of moss and weed in the garden and kill it off.So you'll be left with bits of grass, and black/brown patches.You'll need to re-seed those patches for the grass to take over the garden again from the weeds.This is what I have done, and I will re- edit this around May 2024 if it didn't work.But this stuff looks like it goes on the hunt for weeks - I covered my lawn in it and it only killed weeks and moss.I think where reviews have said it killed their lawn, may not have realised there was moss under the grass.

The product is good but not as good as the powder / granules tub ! It is not as strong need to use a lot more and it's more expensive

I ordered 3 containers which were supplied as two and one , very dissapointed to be charged two delivery charges , because there is an absence of a box
