Do you have enough sun for a good lawn?

Also need good drainage. Otherwise, moss will always take over.

Yes it gets enough sun. The biggest issue is that it's a slight hill and the water drains down. I think the biggest problem is that it is on a hill and a few years ago the grass died off and the moss moved in. The previous owner had the sprinkler system set up incorrectly and the grass was burnt and died off before we realized why.

Moss moved in because conditions are correct for it, among them moist, compact soil, and low light.

wynswrld98 did you lime in the spring and fall or twice in the fall?

Spring and Fall. I think McLendons has Super Sweet Lime on sale right now if you need any... I have read you need to spread out application of lime and fertilizer otherwise I think lime hurts the nitrogen or some such so I spread them out a few weeks from each other. If I were you after you get the moss out of the lawn I'd apply the Super Sweet Lime since it's still early to be seeding a lawn here due to temps pretty low at night and recommend applying a "Seed Starter Fertilizer" when you seed it.

Moss will die off a bit with warmer weather. You can rake out a good deal of it and then be diligent with your liming going forward. You should begin a regular overseeding schedule too.

Not at all sure about the correlation between using the lime and moss control - one has very little to do with the other. Moss development is not at all dependent on soil pH - it thrives on both acidic and neutral to slightly alkaline soils and liming has no ability to "kill" moss. It is not considered necessary unless your soil is strongly acidic - below 6.0.

And moss is not all that fussy about shade versus sunlight either. Grows easily in full sun but does prefer a shady location. What it thrives on is compacted soils, poorly draining or wet soils and nutrient poor soils. And these are soil conditions that limit the healthy development of turf grasses as well. Correct these issues and the lawn will begin to recover and a healthy lawn will outcompete both lawn mosses and other weeds.

gardengal: if you're referring to my posting, the facts I quote are correct as far as what has transpired in my lawn and ZERO moss in it this winter/Spring even in open dirt areas so draw your own conclusions. I always fertilize in the fall with an organic lawn fert (e.g., Dr. Earth), the only change I can see I made was the Lime. I didn't aerate or add soil or anything like that last summer/fall, the only difference I can see is the extra lime.

I think the lime is more about creating more favorable conditions for the grass to compete than killing the moss itself.
