Jeffersonville sits along the north bank of the Ohio River, where the landscape shifts from low-lying riverfront flats to gently rolling residential streets just blocks from the Big Four Bridge. The native silt clay soil that underlies most of 'Jeff' holds moisture stubbornly, making amended planting beds and well-draining mulch layers essential for healthy root systems. With 45 inches of annual rainfall and a growing season that runs from late April through early October, organic mulch breaks down at a steady pace, requiring consistent replenishment to keep beds productive through the humid summers. Neighbors in Clarksville and New Albany face nearly identical conditions along the river corridor, while Sellersburg and Middletown deal with similar clay-heavy soils as the terrain rises to the north. The right combination of mulch, blended soil, and decorative stone makes a measurable difference in this part of southern Indiana.
