Kennewick soil is:

These factors influence how you should approach lawn care in Kennewick. The alkaline soil may limit nutrient availability, especially iron and phosphorus. Despite having decent phosphorus levels (46 ppm), the high pH can make it harder for grass to absorb.

- Water deeply but infrequently to encourage deep root growth
- Mow at 3-4 inches to help cool-season grasses withstand heat
- Use fertilizers formulated for alkaline soils
- Consider a soil test kit to monitor nutrient levels

Great Custom Lawn Care
We are in a newly developed neighborhood that used to be desert. After using Sunday’s spring care box we had the greenest and most lush lawn in our neighborhood of 25+ homes. After getting our soil sample results we purchased additional fertilizer. That along with the summer car box kept our lawn in great shape. It’s October and we still have the nicest looking grass on our block.
