@Stewartmarsha11@dudleygolfclub A cheaper more disruptive option of mole ploughing to a collector drain on the collar? Unfortunately, that water still needs to get away.
@iTweetTurf @asianturfgrass If it is a new property may all greens to get a full initial picture, then I would recommend grouping into greens that had similar construction types or dates and have similar performance. Resulting in maybe 3 to 4 greens per 18 holes.
