Tall Fescue Aeration Guide
Core aerate in early fall (September) right before overseeding — this is the single most impactful maintenance event for fescue lawns. Use a core-pulling aerator, NOT a spike aerator. Pull 2-3 inch cores on 3-4 inch spacing. Aeration relieves soil compaction, improves water infiltration, and creates perfect seed-to-soil contact for overseeding. Leave cores on the lawn to break down naturally. Annual aeration is recommended for all fescue lawns — clay soils especially benefit. Aerate when soil is moist but not waterlogged for best core depth.
Frequently Asked Questions
When should I aerate fescue?
Early September, right before fall overseeding. The aeration holes give seed better soil contact, and the grass has the full fall growing season to recover and fill in.
How often should I aerate fescue?
Annually for most lawns, paired with fall overseeding. Heavy clay soils benefit from aeration twice a year — once in early fall and once in early spring.
Should I pick up the plugs?
Either way works. Leaving plugs to break down returns organic matter. Picking them up gives a cleaner look for overseeding. If overseeding, rake plugs to crumble them over the seed.
