Leaving the soil in a natural state is the most beneficial approach for an existing native California oak tree. These trees have evolved in specific ecological conditions and thrive when their native environment is preserved. Maintaining the integrity of the soil allows for the natural exchange of nutrients and supports the existing ecosystem, which includes essential microorganisms, fungi, and other plants that contribute to the health of the oak.

Natural soil conditions help maintain adequate moisture and support deep root systems, which are crucial for the tree's stability and longevity. Disturbing the soil could lead to compaction or erosion, impacting the health of the tree and surrounding vegetation.

In contrast, cutting back the tree for shaping could cause unnecessary stress or damage, while moving it to a sunnier location might not align with its natural habitat preferences and could adversely affect its growth. Heavy fertilization may lead to nutrient imbalances and harm the tree rather than helping it flourish, as native oaks typically do not require heavy inputs.
