Aeration is done when the turf can recover quickly from the disturbance and still grow strongly, which in many regions is in spring as cool-season grass transitions from winter dormancy to active growth. Because the grass isn’t facing hot summer temperatures, it experiences less temperature stress and can push out new roots and shoots to fill in the holes left by the aeration. This timing also helps relieve soil compaction and improves air, water, and nutrient movement just as the plant begins its best growth phase. The other reasons aren’t the main driver—spring moisture levels and regulatory requirements aren’t the key factor, and the idea that tasks are faster in spring isn’t the primary consideration.
