How much lime is needed for the lawn and when to apply. I applied lime last week and the grass is turning to dark green. Is this the indication that enough lime is applied? Is it necessary to apply twice a year? Also how much potassium is needed for lawn? If added more will it be helpful for a recovering lawn?

Lime and potassium are applied to lawns based on the results of some simple soil tests. The soil tests will tell you about the pH of your soil (meaning how acid or alkaline it is) which is what is affected by lime. The tests can also tell you how much nitrogen, phosphorus and potassium you need to add, if any. Your local County Extension can help you with the tests and with interpreting the results.

This way you will know if either of these are really necessary for your particular lawn, and how much to add. As with many things in life, too much of even a "good thing" can be detrimental, so you really need to run the tests to be sure your well-intended efforts are indeed helping! Good luck with your lawn!
