I have 1/3 acre Lawn. Lots of Moss. I believe first step is apply sulphate of iron followed by feeding. Now 4th September, if I apply sulphate now when should I see effect and when should I apply feed or seed if necessary?266
Feeding in March and July is essential to allow grass compete with moss by replacing nutrients lost when grass mowings are removed. Mulch mowing returns those nutrients and less feeding is required.
You can also use an autumn lawn fertilizer in September.
