Landscaping, Planting and Grading

<p>Piedmont clay has fine particles that pack tightly together. Water moves through it slowly, air moves through it even more slowly, and roots that hit a compacted layer tend to circle instead of pushing on. Dig a hole in that clay with a smooth-sided auger or a wet shovel and you glaze the walls, effectively lining the hole. The plant then sits in a bowl that fills with water and stays full.</p> <p>The fix is not dumping a bag of premium potting mix in the hole either. That creates a soft pocket the roots refuse to leave. What works is a wide, shallow, roughened planting hole, backfill amended gradually rather than abruptly, and the root flare set slightly high so it never sits in standing water.</p>

<p>Anything specified for a Piedmont bed has to survive three separate stresses: winter cold snaps, a hot and genuinely humid summer, and periods where clay stays saturated for days. Native and Southeast-adapted material handles that better than whatever is trendy at the big-box garden center in April. Sun exposure gets mapped honestly, too — a bed on the north side of a two-story house under mature oak canopy is a shade bed, no matter what the homeowner hoped to plant there.</p>

<p>Grading is the least glamorous line on a landscaping estimate and usually the most important. Common problems around Triangle homes: soil built up above the siding line, negative slope pushing roof runoff back toward the foundation, downspouts dumping straight onto a bed and eroding the mulch out of it every storm, and low spots that stay soft for days after rain. Reshaping the ground, extending discharge away from the house and correcting fall solves the cause. Adding more mulch on top only hides it.</p>
