As many may do - I use Sulphate of Iron for Moss control - But

[utterlydiy]

As many may do - I use Sulphate of Iron to help control moss in the lawn etc.

But I've read by using the sulphate, Lime should be used to maintain the Ph above 5 as the sulphate makes the soil acidy.

If this is so, how much lime should be used per SQ/M.

Id be surprised if using moss killer had any real effect on the acidity of the soil.

Id be interested to hear what others think on this

You'd need to test your soil first to see what it's pH level is first. Info re: liming/soil acidification can be found here. https://www.rhs.org.uk/advice/profile?pid=144

Find out what commercial lawn moss killer mixtures contain.

As an example: https://www.jonathangreen.com/wp-content/uploads/2018/03/sds-JG-Lawn-Moss-Control.pdf

That says 74.2% limestone, 25.8% iron sulphate.

Thanks,

Read elsewhere, by using Sulphate of Iron only it increases the acid.

Purchased some chemical soil testers, as yet to test the soil in the infected areas.

Thanks for the replies.
