A dogwood outdoor sofa adds natural elegance to any patio or garden, but its wood is prone to splitting if not properly cared for. To prevent splitting, start by choosing high-quality, well-seasoned dogwood lumber for construction. Apply a high-grade outdoor wood sealant or oil finish every 6-12 months to protect against moisture absorption and UV damage. Keep the sofa in a shaded area when possible, and use protective covers during harsh weather. Regularly inspect for cracks and sand minor imperfections before they worsen. For extra protection, consider using wood stabilizers or epoxy fillers for vulnerable joints. Proper maintenance will ensure your dogwood sofa remains beautiful and durable for years.
