The answer to 'how to install aeration' is to use a core aerator to punch small holes in your lawn, allowing air, water, and nutrients to better reach the roots. This helps reduce soil compaction and improve the overall health and appearance of your lawn.
Start by mowing your lawn to the recommended height. Then, use a core aerator to punch 2-3 inch deep holes every 6-12 inches across your lawn. Make multiple passes in different directions to ensure even coverage. After aerating, water your lawn thoroughly and apply any necessary fertilizers or soil amendments. Aeration is best done in the fall when grass is actively growing.
