The Unique Landscape of Westfield
Westfield sits in growing zone 6a, which means beds go through a hard freeze in December and then repeated thaw cycles in February that heave shallow roots right out of the ground. The silt loam under most Westfield yards holds moisture well but crusts over and sheds water when it bakes dry in July, so bare soil in a front bed can shed a summer thunderstorm instead of absorbing it. A 3 inch mulch layer buffers both problems by insulating roots through the freeze thaw swing and keeping the silt surface open so rain soaks in. With roughly 40 inches of rain a year, much of it arriving in heavy May and June downpours, mulch also stops silt particles from splashing up onto siding, walkways, and lower plant foliage. Newer Westfield subdivisions off Ditch Road and Spring Mill often have compacted builder subsoil near the surface, and mulch is the simplest way to start rebuilding structure without digging up finished beds. Over a few seasons the bottom of the mulch layer breaks down into the silt loam and turns it into something roots can actually move through.
