Liming depends on your soil pH. I would think that once every 5 years or so would be fine unless you do a soil test and find that the pH is still too low. Your County Extension Office can assist you with having your soil tested.
Fertilize with no more than 1/2 to 1 pound of nitrogen in spring after you have mowed the grass twice, and again in fall (around late October). Apply a product with a 3-1-2 ratio of nutrients as this is roughly the ratio of nutrients grass takes in. So, for example, if you purchased a 15-5-10 fertilizer (15% nitrogen), you would apply about 7 pounds per 1000 square feet (1 pound / .15 = about 7). If you purchased a 21-7-14 fertilizer (21 % nitrogen), you would apply about 5 pounds per 1000 square feet (1 pound / .21 = about 5).
Thanks for the question. Please stop in again soon!
