When it comes to your grass there are several steps needed to produce a truly beautiful and lush lawn.
These would include aerating, seeding, fertilizing, mowing at the right height. Unfortunately, the one step many people choose not to do is to add lime to the soil.
What lime does, basically, is raise the pH of your soil. Ideally, pH levels in your lawn should be between 6 and 6.5.
Around the Piedmont Triad area our soil tends to be naturally acidic, mainly due to the heavy red clay we’re all oh so accustomed to. It tends to range from 4.25-5.5 if left untreated. That range of pH is actually a great range for a lot of plants, such as Azaleas, Camellias, and most evergreens. It is not, however, ideal for lawns!
When the soil that grass is growing on is in the correct pH range, it is better able to absorb nutrients that are locked within the ground, and will generally be much healthier.
To increase the pH by one level we recommend using 40lbs of lime per 1000 square feet. In other words, if you have a pH of 5, adding 40lbs of lime per 1000sf will raise your pH to 6.
It should be noted that when you use pelletized lime it will take 6 months to take full effect.
One other choice is to use a product known as fast-acting lime, which works in the same season you spread it, and will also cover a larger area.
Whichever choice you go with, just keep in mind that adding lime is going to make everything else you add to your lawn work better!
