Soil Amendment Tips
- To raise pH: Add garden lime (calcium carbonate) at 5 lbs per 100 sq ft. Retest in 3 months.
- To lower pH: Add elemental sulfur at 1 lb per 100 sq ft, or use acidifying fertilizer. Retest in 3 months.
- Your soil is in the ideal range for most plants. Maintain with regular organic matter additions.
