The most common problem we see, during our investigations of newly planted landscapes, is the application of too much water. Saturated soil conditions push out oxygen, and without oxygen roots cannot function. Expensive landscapes turn disastrous and trees never thrive. It is critical that one understands how much water is being applied to plants. This involves conducting a water audit and soil moisture monitoring (before and after irrigation with the use of a soil auger) until the moisture regime is understood.
