Apply as directed. I had difficulty applying it and probably applied 50% more than instructed, I included some blue dye in the mix, so I could clearly see how much was being applied.
The moss quickly went black, with no damage to the grass. I applied it with a electric pump sprayer (£21), end of tube in a 10 litre bucket. I can highly recommend this product from hsd, and the water pump sprayer from Amazon.

The manufacturer advises leaving at least 4 weeks between applying any Lawn Fertiliser after using the Lawn Tonic. They confirm not to mix chemicals.
After applying how many days later can I use a lawn rake to remove the moss?
We would advise to rake the treated area around a week dependant on the weather conditions.
Hiya, does this product stain hard surfaces ? And also can you use a less stronger application I.e 500ml with 4 litres of water to kill moss or do you have to use a litre ?
This would stain any hard surfaces, it is only to be used on grass. You do need to follow the guidelines to obtain the best results.
