What is the solution?
There is no way to get rid of caliche if it’s in your soil. But, there are ways to help your plants live with it.
Planting a wide enough hole for the mature size of the plant’s roots to extend out is extremely important. This will help because the roots of the plant probably won’t be able to extend out any further than the hole you originally dig.
Remove the caliche from the hole you’ve dug and replace it with an amended soil that will help your plant grow.
If the drainage is bad, create a chimney to allow excess water to drain away from your plant.
Always use native desert plants when planting in caliche. They are much better adapted to survive in caliche than other plants.
