ferrous sulphate

[brownfingers]

I've been prowling the interweb as to using ferrous sulphate to tart a lawn up. I see that various dosage rates have different effects. Weak doses just green the lawn. Medium doses harden the lawn ready for winter, and high doses kill moss. What I can't find is how often to apply it at the different strengths. Any advice would be appreciated.

Any advice would be appreciated.

You won't like it but ... give the lawn the conditions it requires, then you won't need to add bits of this & that. It's a losing battle if conditions aren't right, or if you're trying to grow the wrong type of grass.

Or learn to love the moss ~ call it a Japanese lawn. They're lovely & springy under the feet

Using Iron Sulphate on Lawns

Been on lawnsmith. It gives masses of info, except how often to do it. IE: once a week, twice a week, monthly, twice a month?
