Balance acidic lawn soil fast with Jonathan Green Mag-i-Cal for lawns in acidic soil. Raise soil pH with highly soluble calcium carbonate so grass can use the nutrients you already apply. Strengthen roots, deepen color, and turn thin, tired patches into a lawn that fills in and stays green.
Key Features
- Fast pH lift: Highly soluble calcium carbonate adjusts pH upward for better nutrient uptake.
- Healthier soil life: Added humates support soil structure and long-term lawn vigor.
- Consistent results: Improve growth in areas held back by poor, acidic, or hard ground.
- Yard-friendly size: An 18 lb bag is easy to carry and spread where you need it.
Applications
Use when a soil test shows low pH or when grass looks yellow despite regular feeding. Apply with a broadcast or drop spreader and water in to move nutrients into the root zone. Treat trouble spots or cover the whole yard, then recheck soil pH seasonally to keep it in the ideal range for turf.
