Del Rio Stone Delivery

Will rock mulch make my yard hotter in summer since we already deal with triple digit heat?

This is a real consideration in Del Rio. Dark colored stones like black lava rock or dark crushed basalt do absorb and radiate significant heat and are not ideal for planting beds where roots run close to the surface. Lighter materials like decomposed granite, cream limestone, or buff colored river pebble reflect more heat than they absorb. Placing stone in open areas, pathways, and borders rather than directly over shallow rooted plants reduces any heat stress concern while still delivering the water conservation benefit.

How deep does decomposed granite need to be for it to actually stay in place and not wash away when we get a big rain?

Del Rio's rainfall is infrequent but occasionally arrives in intense bursts that can move loose material quickly. A 3 inch compacted layer of decomposed granite holds up well under most rain events, especially if you install steel or plastic edging around the perimeter to contain it. Areas with any slope benefit from going to 4 inches and compacting the material with a plate compactor or a hand tamper after initial spreading. Avoid applying decomposed granite over areas with significant drainage flow paths where channeled water velocity would dislodge even compacted material.

Is river rock or crushed stone better around the foundation of my house here in Del Rio?

For foundation borders in Del Rio, crushed limestone or pea gravel sized river rock in the 3 to 4 inch depth range is ideal because it promotes drainage away from the foundation during heavy rains rather than directing water toward the structure. River rock in the 1 to 3 inch size range is easy to maintain and does not blow away in spring winds. Avoid very fine crushed material directly against the foundation because it can retain moisture against the concrete, which is counterproductive in a climate where you want fast drying conditions near the structure.

Can I use caliche from my own yard as a gravel substitute or is it worth buying actual gravel?

Caliche from your yard is inconsistent in size and hardness, and it tends to soften and become muddy when it gets wet, which makes it a poor substitute for processed gravel in driveways or high traffic areas. For pathways and decorative applications, native caliche can work as a temporary solution but it will break down and compact unevenly over time. Buying quality processed decomposed granite or crushed limestone gives you a consistent particle size and long term stability that raw caliche simply cannot match.

What is the best stone for a dry creek bed in my yard to handle drainage from those sudden rainstorms we get?

Del Rio periodically receives intense short duration storms that overwhelm the clay soil's ability to absorb water quickly. A dry creek bed built with river rock in the 3 to 6 inch size range moves that excess water efficiently while looking natural in the local landscape. Line the creek base with landscape fabric to prevent the rocks from sinking into the clay over time, and use a slightly larger 6 to 8 inch anchor stone on the outer edges to keep the channel defined during high flow events. The rounded surface of river rock also reduces turbulence that can erode channel edges over repeated storms.

Does stone need any maintenance or is it truly a set it and forget it solution for a yard in Del Rio?

Stone is lower maintenance than any organic ground cover in Del Rio's climate, but it does require occasional attention. Leaf and debris buildup in rock beds creates an organic layer on top of the stone that seeds will germinate in over time, so a seasonal blowout with a leaf blower keeps beds clean. Decomposed granite in high traffic areas may need a light top dressing every three to five years as fines work into the soil below. Edging maintenance once or twice a year keeps stone contained and the overall look sharp without major effort.
