It all depends upong the Ph. Are there plants growing? What kinds?

Here in Reno, our soil is alkaline also. Most plants don't seem to mind (the natives require it) but, you may want to add a lot of garden soil and compost to help lower the Ph but especially so the plants have something nutritional to grow in. Alkaline soils, whether clay based or sand based, don't have a lot of organic matter or they wouldn't be alkaline.

For most of my yard, I supplimented the planting holes by mixing garden soil into the native soil. For acid loving plants like azaleas, I replaced the soil completely.

Trees are a different problem as their root systems don't stay contained like a shrub or perennial's roots would. If you fortify a tree planting hole, you restrict root development because the roots would rather stay in a container of nice soil then grow out into the alkaline soil.

Shrubs I have replaced are easy to dig up because their roots haven't gone anywhere.
