What does forking your lawn do? Forking before over seeding is a good idea. New root growth from young seedlings channels easily down the holes. A rake after a spike closes the surface openings and seed will settle into the remaining indentations. The deeper the tines the better, grass roots often stop at the depth of aeration.
When should you fork a lawn?
Spring is a great time to aerate a lawn made of warm season grass. This is when the grass is actively growing and it will recover quickly from the process. The cooler season lawn is better aerated in fall. If you are not sure if you need to aerate, simply dig a section of turf out that is at least 1 inch (2.5 cm.)
Is forking good for your lawn?
No! Not if you want to relieve the compaction and promote healthy roots. Aerating with a garden fork will help improve air and rain percolation, but forking a lawn won't reduce the compaction. The garden fork is a beautiful thing – but use it for digging, not for aerating!
When should I scarify my lawn?
Late spring and early autumn are considered to be the two best times to scarify your lawn, capitalising on both the weather and the conditions of the ground. Most garden experts agree that the ideal time to scarify your lawn is when your grass is growing strongly.
Do you have to seed after aerating?
Within 48 hours after you aerate you should over seed, fertilize, and water your lawn. The seed, fertilizer, and water will have the best chance to get down into the holes made by the aerator if applied soon after aeration. If the fertilizer contains weed control, your grass seed won't germinate properly.

Is lawn aeration a gimmick?
Lawn aeration is beneficial to almost any soil but it offers the most benefit for soils that are heavily compacted. Clay soil, for example, has very small pores and does not allow air exchange. It also restricts the growth of roots and encourages microbacterial activity that is present in healthy soils (source).
