Gardener advise on the value of testing soils and what to do when the results are in
Limestone is used to raise the soil pH but no more than 50 pounds/1,000 sq. ft at one time When changing the soil pH to make it more alkaline, you first need to know what plants are going to be grown, then how much of a product to use. Certain plants like acid soils and therefore, need pH conditions to be in the zone of 4.5 to 5.5. Other plants like their soil acidic but less so in the zone of 5.5 to 6.5. Certain other plants might prefer more alkaline soil conditions and tolerate pH ranges from 6.5 to 7.5. Changing the pH so that it is more alkaline calls for applications of lime. The most commonly use materials is dolomitic lime. This can be applied most anytime of year, but the general rule-of-thumb is to never apply more than 50 pounds per 1,000 sq. ft. in one application. If more is called for then you should split the application and wait 6 to 8 weeks between.
