It’s also important to keep your KBG slightly taller when you mow. The taller the grass blades, the deeper you’ll encourage the roots to go into the soil, as shoot height is proportional to rooting depth. Shorter grass = shorter roots, and vice versa. A good mowing height for this grass is 2 to 3 inches tall.
Never take off more than one-third of the grass’s height with the lawn mower, and leave the mulched grass clippings on the lawn to add nitrogen back into the soil for an added dose of fertilizer.

Minimizing Thatch and Soil Compaction
Excessive thatch is a regular problem in KBG lawns, unfortunately. The thatch builds up quickly because of regular fertilization, creeping rhizomes, and quick, lush growth. It becomes problematic because the organic material lays undigested on the soil surface and keeps water and air from moving into the soil and reaching the roots. Thatch also encourages insects and disease problems.
Plan to dethatch your lawn yearly in either April or September when the lawn is actively growing. Never do it during the summer when it’s gone dormant because of the heat.
