Your property’s natural slopes and rock formations aren’t obstacles—they’re design opportunities waiting to be unlocked. Start by examining three key elements: slope steepness, soil behavior, and water movement patterns. These factors determine which landscaping solutions will work best while keeping your yard stable.

Slope Evaluation Made Simple

Grab a measuring tape and level to categorize your incline. Gentle slopes (under 30%) allow for simple planting beds, while steeper grades might need terraced structures. Watch where rainwater pools during storms—these areas often need drainage upgrades to prevent erosion.

Soil Secrets Revealed

Perform a quick soil test using this method:

  • Scoop handfuls from different areas
  • Note texture and moisture retention
  • Check for rock content

Sandy soils dry fast but shift easily, while clay holds water like a sponge. Most yards benefit from mixing in organic matter to improve stability. Don’t fight existing rock formations—use them as natural anchors for plantings or stepping stones.

Notice how sunlight hits different zones? South-facing slopes bake in summer heat, creating perfect spots for drought-tolerant species. North-facing areas stay cooler, ideal for shade-loving groundcovers.
