Hi all,

Can anyone help me how to mix this stuff in a 8l watering can for moss please? I was thinking 30grams to 8l watering can but maybe i'm completely wrong. I have a huge bag of the stuff.

Thanks in advance. Link below.

Their application rates seem very Broad but I would have thought nearer 25g per litre. 8 litres won't cover much of an area though

Thanks for reply. I'm very confused. Just don't want to burn the lawn really. 50kgs/ha = 5grams / sq meter. I guess i just have to see how much sq meter a watering can will cover and go from there. 25grams per litre seems like alot.

It's not how far you can get with a watering it can. It's the application rate necessary.

They state 10-50kg/ha 300-600 litres/ha.

Even their min 10kg to 600l is 17g/l and that's just to green up the grass. And that would cover 16sq m.

Hmm ok, my lawn is about 70 sq meters. I could cover lawn with 5 or 6 watering 8l watering can. I thought maybe 50 grams per watering can but you think this is not enough? Maybe i can contact them.

Based on their application rate for a 25kg bag it's still over 20g to the litre. 50g in 8 litres is a waste of product, time and energy.

Thanks, i think you are correct. I found this link which is a similar product and gives better idea of how to mix it. I think 25grams / litre might be best option.
