Core Aerating Best Practices
Looking for some advice that I haven’t found on any of the guides. I’m in western Washington outside Seattle (Zone 9a) and while I haven’t had the budget to do a full overseed, I’m planning to core aerate this fall and ideally next spring and spread humichar. My soil is fairly compact and I think it’s a small step I can go in the right direction (hoping to do full overseed next fall). I plan to rent a gas powered aerator for this. My questions are as follows:
- does timing of the aeration matter? Or weather?
- optimal depth to set the tines on the aerator?
- are multiple passes desired or just one?
- is there a recommended height of cut for the lawn? Currently I’m mowing at 4”
Appreciate the help!!
