Welcome back to my soil series! Here is a popcorn read for you! One thing that I noticed throughout the years while analyzing and giving recommendations regarding lawns is always giving my customers a time line to raise their pH. pH is known as the measurement to determine if something is acidic or alkaline on a 0.0 to a 14.0 scale. 0.0 being acidic, 7.0 being neutral, and 14.0 being alkaline. Every day items have their own pH. Here are some great examples to put the pH scale in perspective: orange juice is a 3.0, distilled water is 7.0, and bleach is a 13.0. Our lawn likes a pH of 6.2 to 6.8, most vegetables like the pH slightly acidic, azaleas and rhododendrons like a pH between 5.0 to 5.5, and cabbage and cauliflower likes a pH of 7.5 to 8.0.
When our soil pH is off, our lawn or plants will not thrive. When our pH in our soil is too alkaline, our plants cannot utilize many of the nutrients in the soil. When our pH is too low, it creates deficiencies for our plants. It is very easy to alter the pH in your soil too!
To raise the pH, you need to add lime to the soil. The general rule of thumb is that you need 50 pounds of lime for every 1,000 square feet to raise the pH up by half of a point. That means to cover one acre of lawn, 45,000 square feet, you need 2,400 pounds of lime. To lower pH, you need twenty pounds for every 1,000 square feet to lower pH in clay soil or you can do ten pounds for every 1,000 square feet to lower pH to lower pH in sandy soil.
We need to remember when we are trying to alter the soil, that we need to make sure our pH is correct in order that deficiencies do not happen as well as to make sure our plants can take in the nutrients that they need to thrive! Thank you so much for reading if you have a popcorn topic or questions send it in and I will do a popcorn article with an answer!
