I get many questions about the proper Liming of a lawn all the time. The questions vary, but these are often the most popular.
Should I lime my yard?
How often should I lime my lawn?
How much Lime should I put down?
Whats the difference between powdered lime and pellets?
When is the best time to lime?
Will lime kill moss? (I answered that one in my last post)
I have found 2 links to answer these questions . I will add some finer points to liming later, but these links should answer most of you questions.
more detailed Liming information from Ontario Ag dept.
One last thing. From these articles, you will understand that all lime isn’t equal. The magic number is usually the CCE (calcium carbonate equivelent) .
CCE of 100 means that the lime you are buying potent lime. It is a measure of against pure calcium carbonate.
The less the CCE, the less liming power the lime has. You will then need more lime to do the same job. Its not that lower CCE liming materials are bad, they just will require more. I have seen Lime sold at Big Box retailers with a CCE as low as 48%. It will take you twice as much of this lime to what a 100% Lime material will do.
Spend you money wisely. Sometimes the 3 for 11.95 deal at the garden center isn’t such a good deal after all.
In my next post, I will detail how to calculate these numbers if you are applying lime from a soil test recommendation. Happy Liming
