Live Oak

Quercus virginiana

Southern Live Oak tree
Trees

A broad, long-lived evergreen oak from the American Southeast, with dark green leaves and a dense, spreading canopy. It gives the deep shade of a traditional shade tree, has no thorns and handles both Phoenix heat and cold, which is why it appears in parks, golf courses and larger yards across the Valley.

Living with it in the Phoenix Valley

Watering

Follow the tree schedule in our Landscape Care guide. It is not a desert native and needs more water than a palo verde or mesquite to look its best. It responds well to deep watering on drip.

Pruning

Seed-grown trees vary in form, so early structural pruning sets the shape. On mature trees, lift the lower branches gradually for clearance and views while keeping as much shade as possible.

Spring leaf drop

Each spring it sheds most of its old leaves just as new growth emerges. It can look alarming for a week or two, but it is normal.

Pests

Aphids are the main pest. They distort new leaves and leave sticky honeydew and sooty mold on whatever sits below.

How our designers use it

Deep shade for larger yards

Its broad canopy shades a lawn, play area or large patio more fully than most desert trees.

Traditional and formal designs

Dark, evergreen foliage gives a classic, established look that suits Spanish Colonial and traditional homes.

Drives and walkways

Planted in a row, it frames a long drive or entry walk.

Good to know

Around the pool

Spring leaf drop and fall acorns add up to real cleanup, and roots spread wide and shallow under irrigation. We keep it well back from pools and paving.

Acorns

Acorns that fall into gravel or decomposed granite will sprout if not raked up.

Pets

The ASPCA lists oak as toxic to horses; acorns and leaves are the concern.
