Thatch
Thatch is a tight, brown, spongy,
organic layer of both living and dead grass roots and stems that
accumulates above the soil surface. The interactions among environmental
conditions, soil conditions and management practices (irrigation, mowing,
fertilization) influence the rate and extent of thatch accumulation. |
Power Raking
This method of thatch removal has
been used for years. Light (shallow) power raking may be beneficial if
done often. Deep power raking of a thatchy lawn can be damaging, and often
removes a substantial portion of the living turf. Used properly, power
raking of wet, matted turf can speed spring green-up by letting air move
into the root zone and warm the turf. |
