## Questions & Answers

**Q: What is the required average coverage per litre**
A: The Lawn Tonic liquid is added to water for use in a hand-held sprayer or watering can. There are three main applications:
(I) add 0.25 ltr of liquid to 5.00 ltr of water for grass greening - covers 50m2
(ii) add 0.50 ltr of liquid to 5.00 ltr of water for turf hardening - covers 50m2
(iii) add 1.00 ltr of liquid to 4.00 ltr of water for moss removing - covers 50m2
The container holds five litres of liquid.
For 'correct' application it is best to have the area marked and keep spraying/watering within the boundary until the content emptied; should aim to be fairly even over the area. Bigger area...just repeat; smaller area, then reduce proportionally.
I use this product for moss removal: never succeeds on first application so I repeat two weeks later.

**Q: Do you need to rake the grass after it turns black or can u just leave it ?**
A: Rake it and pick up.

**Q: Will using this to treat the grass also help kill off weeds such as clover and thistles?**
A: No, it isn’t a weedkiller. This lawn tonic will, depending on the concentration, kill off moss, green up the grass or harden/strengthen the root structure. It will promote growth and so you may find that the grass will prevent the spread of weeds.  To kill off the weeds you could add a selective lawn weedkiller to the lawn tonic solution and apply both at the same time, ensuring you use the correct dilution rate for the weedkiller.

**Q: I applied this yesterday to my lawn at 250 mls  added to 5 litres of water, can I water the grass afterwards? or just leave it for a few days?**
A: Leave it a few days before watering, beware of frost.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Liquid lawn tonic and moss killer.
*by G***R on 3 May 2025*

The item did exactly what was described. A good product, easy to apply. Just follow the instructions and you will not go wrong.

### ⭐⭐⭐⭐⭐ Satisfied
*by R***E on 8 June 2025*

Very satisfied with this product; my lawn is starting to look nice, green, and lush now, and I swear my neighbors are planning a raid to steal my secret grass formula!

### ⭐⭐⭐⭐ Value for money
*by M***. on 20 March 2024*

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.
