Lime should probably be put down in the Fall. Usually a light snowing of lime in October is good for a couple of years. A soil test is best first. If you lime in the Fall, it will have all Winter to work in. Lime is slow acting. It penetrates about a quarter inch a year and there is no lateral action. Remember, in spite of what Maw West said, “More is not better.” Lime neutralizes the soil – changes the structure and aids in the liberation of nutrients that otherwise would not be available to the roots. It speeds decomposition of organic matter and supplies a small amount of calcium. On a new lawn, it should be raked in. Don’t plow or spade it deeply in the soil (that is always good news!). It is not good to lime and fertilize at the same time. This causes a rapid release of ammonia. Don’t use animal manure. Let it set a few weeks. That is why you lime in the Fall and fertilize in the Spring. If you use weed and feed products, read the instructions carefully. Pre-emergence means just that! Too much lime and as the soil approaches its neutral point it receives less and less iron. A soil test kit is very helpful. Most New England soils are on the acid side. 6.5-7 is fine on a soil test.
Just once a year, I use Miloganite which is an organic fertilizer. As it has nitrogen, it should not be used at the same time that you put down your lime. Cut grass high and leave the clippings on. Learn to live with a few weeds. They are green and you will find life a lot less stressful. Don’t kill it with kindnes. Enjoy it and have time for other things.
