    how come when u thatch, the stuff develops again after only a few months? i have a neighborhood where the customers do all of thier own fertilizing, and maint., but have us come in and thatch every spring, and fall, and spring, and fall......we do it in sept, by april there is a little thatch, we do it then, by sept there is quite a bit of thatch again. im assuming this is from bad fert practices, but im not certain. any ideas?

    what is the height that they mow the grass at and the watering situation that they use?

    The dense mat of tightly compacted, partially decomposed organic matter can also be eliminated by adding core aeration as an alternative to one of your power raking- It may be caused from clients cutting the turf without a bagger-

    I think you just may have answered the question yourself. perhaps they are pumping too much N or improper amounts of fert on the lawns. this could lead to excessive sheath growth causing a lot of thatch come spring and fall. And JVS, not bagging does not lead to excessive thatch. this is a big misconception amongst the lawn community, but it has been proven so.

    Thats just what I was thinking. You can pick up 1 or 2 week old grass from a heavily neglected lawn and it looks like thatch, but if you inspect it you see its just dead grass that will eventually rot, whereas true thatch is a woody product ,actually roots, most often caused by too little water at very frequent intervals. As a result there is never any water down low in the soil so the roots come up lookin for water and PRESTO! thatch.

    I wrote "MAY" It's a naturally occuring event so, there are many contibuting facors to the final outcome- without "seeing" it or knowing the full detials of N or ph et. al

    Bobby there are many factures that maybe contributing to this problem. If the customers are putting down the too much fertilizer, mowing infrequently, and watering too much they are likely to get what appears to be thatch but is also composed of dead grass that will eventually rot away. Soil testing is a service that you may want to try and ad to these customers if you can.

    Are you side disharging? If so that is the likely source of thatch buildup. More so if you lengthen cutting intervals and grass is allowed to become real long. You should never have a thatch issue if you mulch properly.

    mulching and side discharge has nothing to do with thatch. That is a common myth that people have about thatch.
