What Is the Live Oak?
Live Oak (Quercus virginiana) belongs to the Fagaceae family within the Quercus genus. Live Oak is native to the Southeastern United States. Live Oak is also known as Southern Live Oak, Carolina Live Oak, Laurel Oak.
Live Oak displays a large deciduous tree growth habit, reaching up to 80 ft tall with a spread of approximately 60 ft. Live Oak produces inconspicuous catkins.
Leaf size: approximately 6 inches.
How Often Should You Water a Live Oak?
Water a young or newly planted Live Oak every 7–14 days, soaking the whole root zone, until it is established — usually one to two growing seasons. Established trees mainly need water during long dry spells. In a container, water whenever the top few centimetres of soil are dry.

What Soil Mix Works Best for a Live Oak?
Well-draining loamy soil with good organic content. Good drainage is essential for Live Oak to prevent waterlogging, which leads to root rot and fungal issues.
Where Should You Plant a Live Oak?
Choose a spot with full sun and well-draining loamy soil with good organic content. Avoid low spots where water collects after rain.
Live Oak is suited to USDA Zone 7a – 10b.
Plant container-grown or balled-and-burlapped trees in spring or early autumn, setting the root flare at soil level, and water well after planting.
How Far Apart Should You Plant a Live Oak?
Live Oak can spread to about 60 ft (18.3 m) and reach about 80 ft (24 m) tall. Space plants about 60 ft (18.3 m) apart so mature crowns don't crowd each other, and plant at least half that distance from buildings, fences and paths.

How Do You Prune a Live Oak?
Prune Live Oak while it is dormant in late winter: first remove dead, damaged and crossing branches, then thin lightly for shape.
If it flowers in spring, prune right after flowering instead so you don't remove next year's buds. Never take off more than about a quarter of the tree in one year.
How Do You Care for a Live Oak in Winter?
Live Oak is hardy down to USDA zone 7a, so once established it can stay outdoors through winter in that zone and warmer ones.
Water deeply in late autumn before the ground freezes, and spread a 5–8 cm (2–3 in) layer of mulch over the root zone, keeping it away from the trunk.
Young and container-grown trees need extra protection: roots in a pot freeze much more easily than roots in the ground.
How Do You Propagate a Live Oak?
Live Oak can be propagated through acorns, grafting. Similar propagation techniques also apply to english oak plant care, which shares the same genus.
Is the Live Oak Toxic to Pets and Children?
Pet safety not verified
The ASPCA does not list Live Oak, so we can't confirm whether it is safe for cats and dogs. Keep pets from chewing it as a precaution.
This is a general caution, not veterinary or medical advice. If your pet ate a plant, contact your vet or animal poison control.
