On one of my recent site visits there were a number of puddles that had developed as a result of there being no provision for surface drainage. Being almost flat water collects in the smallest depressions as most topsoils are of a heavy loam texture. The infiltration is minimal in these soils and after a little use these depressions become muddier and muddier.
There is nothing that can be done at this time other than keeping off these pitches until there is sufficient drying out. The only real solution short of installing close spaced drains is to regrade the pitch in the summer to create an adequate gradient to promote surface water run-off. Aerating the pitch by vertidraining does not alleviate the situation especially if the subsoil is of a clay texture.
