Caldwell, ID lawns average 2648.5 sq ft and feature cool-season grasses like tall fescue and Kentucky bluegrass. The soil is slightly basic with a pH of 7.9, which affects how nutrients are absorbed by grass roots.
The soil composition is primarily silt (68%) with moderate levels of potassium, phosphorus and high calcium content. This soil profile creates specific needs for lawn care in Caldwell:
- Watering needs: Idaho's dry climate requires consistent irrigation, especially for cool-season grasses
- Fertilizing timing: Apply nutrients in spring and fall when cool-season grasses actively grow
- Mowing height: Keep grass taller (3-4 inches) to develop deeper roots
The alkaline soil may limit iron availability, potentially causing yellowing grass. A Sunday soil test kit can confirm your exact soil conditions.
Caldwell lawn care should focus on building soil health through targeted fertilization based on these specific soil properties. A Sunday Custom Lawn Plan can help address these unique Idaho growing conditions while providing effective weed control tailored to your yard's needs. Find more lawn tips at The Shed.

Tons of green growth
This seed blend combined with Sunday’s fertilizers worked awesome for our struggling Idaho lawn. I seeded 3 times over the course of about 2 months and we had tons of growth and it’s continuing to fill in bare spots months later.
