What eats live oak trees?
Unlike most oak trees, which are deciduous, southern live oaks are nearly evergreen. They replace their leaves over a short period of several weeks in the spring. Sweet, tapered acorns produced by the trees are eaten by birds and mammals, including sapsuckers, mallards, wild turkeys, squirrels, black bears, and deer.
Are blue oak acorns edible?
Blue oak acorns were among the most commonly gathered, for indigenous Californians thought them to have a good flavour. Acorn meal must first be treated in special ways, for it contains bitter-tasting compounds called tannins that must be removed before cooking the flour.
Do blue oaks lose their leaves?
Normally blue oaks are winter-deciduous, dropping their leaves in the fall. They will normally produce a fall crop of acorns from stored food and then follow up with new leaves in the spring. A tree owner may be tempted to water drought-stressed oaks, but should avoid doing so.
What does a diseased oak tree look like?
Conks are initially white or light-colored and turn black and crusty with age. Infected trees show symptoms of general tree decline including branch dieback, loss of leaves and yellowing or browning of leaves in summer. Trees weakened by drought stress, wounding or other injuries are most susceptible.
What insect kills oak trees?
Borers are beetle or moth larvae that develop under the bark of trees, damaging the wood and eventually killing the tree. Unhealthy trees are more susceptible to borers, so the best defense is to keep your oak tree (Quercus spp.) watered, fed and properly pruned.
Do squirrels eat live oak acorns?
He’s curious about how animals and plants interact. Eastern gray squirrels, the most common squirrels in the Washington area, are opportunistic eaters. That means they will eat just about anything. But they especially like acorns, which are the seeds from which oak trees grow.

Can you eat a raw acorn?
Acorns can be used in a variety of ways. They can be eaten whole, ground up into acorn meal or flour, or made into mush to have their oil extracted. Once you’ve safely leached the tannins from your raw acorns, you can roast them for 15 to 20 minutes and sprinkle them with salt for a snack.

How tall do blue oaks get?
Blue Oaks are medium-sized deciduous trees growing up to 50-82 feet tall, usually with a somewhat irregularly-shaped crown, and a trunk 1.5-3 feet in diameter. The tallest recorded oak was found in southern Alameda County, at 94 feet.
How long do blue oaks live?
Stands of blue oaks are typically 80 to 100 years old. Blue oaks are slow growers, and small plants can be 25 years old. Some blue oaks are as old as 200 to 500 years old.
Can oak tree recover from drought?
Although previous experience indicates that most oak trees that turn brown early, survive and recover the following winter, the effects of drought on trees are not known. As a result, growth is reduced and trees may become more susceptible to insect and disease attacks.
How fast do blue oak trees grow?
The age analysis showed that, in general, blue oaks grow very slowly. On average, trees that were 7 inches in diameter were 100 years old. Although growth was slightly faster than this in some locations, even at the best site, it took an average of ten years for a tree to grow each inch in thickness.
