How do you water a mature oak tree?
Water deeply, to one to two feet, in the outer two-thirds of the root zone. Alternatively, placing organic mulch under the tree can conserve moisture in the root zone by reducing surface evaporation. Mulch also inhibits the growth of weeds, which can compete with oak roots for moisture and nutrients.
Can you overwater live oak trees?
In most circumstances it is not necessary to water mature established live oak trees. Shallow watering can in fact cause additional problems. Over watering or improper watering of oak trees may promote the growth of bacteria that can damage the root hairs and the ability of the tree to absorb water from the soil.

What kind of mulch is best for oak tree?
The very best are oak leaf mulches, which exist, but are quite pricey and are typically derived by stripping wild oaks of their natural mulch base. Even less-than-ideal source material, such as eucalyptus leaves or black walnut roots, can be safely used if properly composted.
Should you mulch around oak trees?
The roots of oak trees extend out a significant distance from their trunks, but most of the absorbing roots are located within a few inches of the soil surface. These roots require oxygen, and a layer of mulch will improve the soil structure and increase oxygen levels so that they can absorb nutrients more effectively.
Where do you water an oak tree?

How do you treat a stressed oak tree?

Should you water oak trees in summer?
