What is lawn sand?

Understanding Lawn Sand Applications in Lawn Care

Lawn sand refers to specialized sand products designed to improve turf conditions through physical and chemical modifications. In Charlotte's Piedmont region with heavy clay soils, lawn sand improves drainage, reduces soil compaction, and provides specific nutrients. The term encompasses multiple products including iron sulfate-sand mixtures (used for moss control and minor nutritional benefit) and construction sand blended with organic matter for general soil improvement. Understanding lawn sand composition and appropriate applications prevents misuse of these specialty products.

Types of Lawn Sand Products

• Iron sulfate lawn sand: Iron sulfate mixed with sand carrier, primarily used for moss control while providing minor iron supplementation
• Soil conditioning sand: High-quality construction sand blended with compost, improving drainage in clay soils
• Topdressing sand blends: Specialized mixes containing sand, compost, and peat designed for turf improvement
• Pure construction sand: Used cautiously to improve drainage, must avoid fine-textured sands that compact further

Application Guidelines for Piedmont Lawns

1. Iron sulfate lawn sand: Apply 10-20 pounds per 1000 sq ft in spring or fall for moss control
2. Drainage improvement: Use soil conditioning sand blends rather than pure sand to avoid creating layering problems
3. Avoid excessive sand: Pure sand applications on clay soils can create impermeable layers preventing drainage
4. Frequency: Apply lawn sand products annually or as needed based on specific soil conditions
5. Combine with fertilization: Pair iron sulfate sand with nitrogen fertilizer for complete spring nutrition

Lawn sand terminology varies widely in horticultural industry. Always read product labels carefully to understand composition and verify suitability for your specific lawn improvement goals. Consultation with soil analysis results guides appropriate product selection.
