The answer to how to care for hardscaping is to regularly maintain and clean your hardscaping features like patios, walkways, and retaining walls. This includes sweeping away debris, pressure washing to remove dirt and stains, and inspecting for cracks or damage. You should also reseal or resand paved areas every 2-3 years to protect against weathering and prevent weeds from growing between pavers.
For retaining walls, check for any shifting or crumbling of the materials and make repairs as needed. Trim back any plants or trees that are encroaching on the hardscaping. If you notice significant damage or deterioration, it's best to consult a professional landscaper for more extensive repairs or replacement.
