The Unique Landscape of Sedalia
Sedalia sits in Zone 6b on Pettis County silt loam, a soil that holds moisture well but crusts over and sheds water after a hard summer downpour. With about 42 inches of rain a year, much of it arriving in heavy May and June storms, bare beds erode and splash mud onto siding and foundation plants. A layer of mulch absorbs that impact, keeps the silt loam from sealing shut, and buffers the swing between 95 degree July afternoons and the sudden cold snaps that follow the October 17 first frost. It also holds soil moisture through the dry August stretch that regularly follows Sedalia's wet spring, which keeps hydrangeas and young trees from stalling. For a growing season running roughly from the April 14 last frost to mid October, mulch is the single cheapest way to cut watering and weeding in half.
