Aeration and Overseeding (AO) season is here! 🌿

In this video, David Lee, Master II Certified Quality Assurance Expert, explains how aeration and overseeding work, why they’re so effective in our region, and what you can expect from Oasis Turf & Tree’s AO program.

With the heavy clay soils in Cincinnati, Dayton, and Northern Kentucky, lawns often struggle to absorb water and nutrients. Aeration and overseeding help break up that soil, improve root growth, and thicken your turf for a healthier, more resilient lawn.

What You’ll Learn:
✅ What aeration is and how it improves soil health
✅ Why double-pass core aeration makes a difference
✅ How overseeding helps fill in thin areas
✅ Why fall is the best time for new grass growth
✅ How turf-type tall fescue improves lawn durability

Key Takeaways:
💡Aeration removes soil plugs (cores) to reduce compaction
💡Roots grow into open spaces for better access to water & nutrients
💡Oasis performs a double-pass aeration for deeper results
💡Overseeding introduces turf-type tall fescue for stronger lawns
💡A starter fertilizer helps new seed establish quickly
💡Full lawn recovery may take more than one season in bare areas

Important Tip:
💧Proper watering after AO is essential—follow your technician’s instructions closely to ensure successful germination and long-term results.
