One little known fact about plant health is that regardless of whether you have added a ton of fertilizer or have the richest dirt available, if the pH is too far off, it won't matter and the plants will not absorb the nutrients in the soil. Grass grows best with a pH around 6.5 to 7.5 which is neutral plus or minus a half a point. All plants have their own pH levels and a detailed guide can be found with a search on Google if you're interested, such as the image below (courtesy of richsoil.com):

pH nutrient availability in lawns

 

   Here at Green Thumb Landscaping, we use a pH tester to check the soil and see whether we need to adjust the acidity or alkalinity of the soil and make adjustments as needed through various ammendments such as lime, iron, copper and aluminum among others (such as blood and bone meal).  Approximately for every half point you are below 6.5 you can add up to 20 - 40 lbs bags of pelletized lime per acre. If the pH is more than a half point off, we recommend doing it in 22 bag increments monthly until the pH is around 6.5. Also beware that it is possible to over lime the lawn and get the pH too alkaline which is just as bad. If you would rather save yourself the math and headache, feel free to give us a call today!
