Lawn and Garden — FAQ
What type of lawn aerator is safest for steep slopes?
Manual spike or core aerators with wide bases are safest for slopes over 15°. They provide stable footing and controlled penetration. Avoid shoe aerators on steep grades and use rolling aerators only on gentle inclines under 12° where you can maintain control.
How often should I aerate a sloped lawn?
Aerate sloped lawns annually in spring or fall when soil is moist but not saturated. Hillside soil compacts faster due to water runoff and gravity. High-traffic slopes may need biannual aeration, while gentle grades with healthy grass require aeration only every 18-24 months.
Can I use aerator shoes on a hill?
Aerator shoes work on mild slopes under 12° with good turf cover. Above 12°, they become unstable and dangerous. On steeper grades, use manual tools with secure footing. Always wear sturdy boots with ankle support when using aerator shoes, and avoid wet or muddy hillside conditions.
What's better for slopes: spike or core aeration?
Core aeration provides better long-term results on compacted slopes by removing soil plugs. However, spike aeration is safer and easier on steep grades where maintaining balance during core extraction is difficult. For slopes over 18°, spike aeration is the recommended method.
How do I prevent soil erosion after aerating a slope?
Aerate when grass is actively growing to allow quick recovery. Apply light compost or sand to fill holes and stabilize soil. Avoid aerating before heavy rain forecasts. On steep slopes, aerate in sections and immediately overseed to establish roots that prevent erosion. Never core aerate dry hillside soil.
Why is aerating slopes more difficult than flat lawns?
Gravity causes tools to slip and lose contact with soil on inclines. Water runs off faster on slopes, creating uneven moisture and compaction patterns. Maintaining balance while applying downward force is challenging. Hillside soil often contains more rocks and roots, increasing tool wear and requiring more frequent adjustments.
