Buying Guide: Key Considerations For Choosing Lime
- Soil test first: Determine current pH and nutrient needs before choosing a product.
- Type of lime: Dolomitic lime adds magnesium; calcitic lime focuses on calcium.
- Form factor: Pellets, granules, and powders differ in ease of application and coverage.
- Organic vs. synthetic: OMRI listings indicate organic suitability; non-organic options may suit fast-acting needs.
- Application rate and timing: Follow label directions; consider irrigation and weather to optimize dissolution.
- Garden size and use case: Large lawns may benefit from bulk powders; containers may favor pellets or granules for even spread.
