Wichita Falls sits on the rolling southern plains where the Wichita River cuts through terrain underlaid with clay loam that bakes into a hard crust in summer and turns slick after a heavy rain. With only 30 inches of annual rainfall spread unevenly across the year, gardeners here depend on generous mulch layers to carry plants through the long stretch of triple-digit heat that sets in well before the first fall frost arrives around November 10. The landscape around Lucy Park and the river corridor shows what consistent organic mulch can do for tree health in this unforgiving climate, and homeowners in Burkburnett and Iowa Park face the same compacted soil conditions when building out their own yards. Whether you are working a shaded lot near the creek bottoms or a sun-baked bed on the open prairie edge of town, bulk landscape materials deliver results that bagged products simply cannot match.
