Q.Lawn
I had pine trees, spruce and balsam in my yard. I removed all of them except 1 red pine. I was wondering how much lime to put on my lawn and which kind of lime for the sour ground from the pine trees?
The need to Lime and how much can be determined by a soil test.
Soil tests will indicate the amount of pure calcium carbonate to apply in pounds per thousand square feet. Working towards a balanced ph level will help bring the soil into balance and allow for optimum nutrient uptake for your lawn.
You can contact your nearest County Extension Office to have a soil test done for a nominal fee.
