Grasscycling hasn't been discovered to substantially increase thatch or disease incidence. Soil compaction decreases root growth as well as recuperative ability, thus increasing a lawn's relative susceptibility to diseases.

Cultivation ought to be done during times when the yard is growing strongly and can benefit from the decrease in soil compaction (spring and succumb to cool-season grass and early summertime for warm-season grass).
