Q: What’s the easiest way to adjust a garden’s soil pH?
A: If your garden soil pH level is below 6, the soil is too acidic for most vegetables, and you need to add ground limestone. If the pH level is above 7.5, the soil is too alkaline, and you need to add soil sulfur. Lawn and garden centers usually have charts showing how much lime or sulfur to add to correct a pH imbalance, based on pounds of material to add per 1,000 square feet of soil. The best way to apply sulfur and limestone is to use a drop spreader for even distribution, working it into the soil afterward. Limestone and sulfur is most effective when tilled into the soil 4 to 6 inches deep.
