Step 1: Mark sprinklers, shallow lines, and pet fencing
Core aerators do real work—great for soil, tough on anything shallow. Mark sprinkler heads, valve boxes, and any low-voltage landscape wiring so the tech can avoid them.
Step 2: Get the soil moisture right
Aim for “moist brownie” soil—not dust, not soup. If conditions are dry, run irrigation lightly 24–48 hours before your appointment. This helps the machine pull clean plugs instead of skipping and bouncing.
Step 3: Mow slightly shorter (but don’t scalp)
A slightly shorter cut improves plug distribution and lets sunlight reach the soil surface for quicker recovery. Keep it reasonable—scalping stresses cool-season turf.
Step 4: After aeration, leave the plugs
Those cores look messy for a few days, but they break down quickly and return beneficial soil and microbes to the surface. Raking them up usually does more harm than good.
Step 5: Water smart for 1–2 weeks
After aeration (and especially after overseeding), consistent moisture matters—but overwatering creates shallow roots and disease pressure. EPA WaterSense recommends watering more efficiently (avoid midday watering, prevent pooling/runoff, and adjust schedules seasonally). (epa.gov)
