What color do oak leaves turn in the fall?
The autumn foliage of some trees show only yellow colors. Others, like many oaks, display mostly browns. All these colors are due to the mixing of varying amounts of the chlorophyll residue and other pigments in the leaf during the fall season.
Named for the light color of its bark, white oak is easily identified by the rounded lobe leaves and unique acorns. Under the right conditions, the fall foliage can be reddish-brown.
Under the right conditions, their fall foliage can be a reddish-brown color that is especially rich on young trees. Their leaves are between 4 and 9 inches long with seven to nine lobes. They start a pinkish color in the spring and transition to dark green.
Red oaks usually provide the best fall color, with pin oaks in second place. White oaks can be colorful, but often turn brown depending on weather conditions. Some oaks, such as live oaks in the deep South, retain their leaves until spring and display no fall color.
The wide spreading branches form an upright, broad-rounded crown. The bark is light ashy gray, scaly or shallow furrowed, variable in appearance, often broken into small, narrow, rectangular blocks and scales. The leaves are dark green to slightly blue-green in summer, brown and wine-red to orange-red in the fall.
Generally the reddish coloring of new leaves disappears quickly in the spring as the leaves finish expanding, but this year, perhaps because of some late frost/freezes and the prolonged cool spring weather, the leaves maintained that slight reddish color well into June.
These green leaves give way to vivid fall color. Most red oak leaves fade to shades of red to orange-red, and they hold their color longer than many deciduous trees. Some red oak trees have yellow fall foliage instead of red.
Species that generally change to a golden yellow in the fall include American elm, black cherry, cucumber magnolia, hop hornbeam, quaking aspen, shagbark hickory, striped maple, sugar maple, tulip poplar and witch hazel.
Yellowing leaves are often the result of chlorosis, or lack of chlorophyll (which makes leaves green). This yellow is usually the due to some necessary minerals being unavailable in the soil which can be the result of an alkaline soil or poor drainage in the hole. Here are some pictures of chlorotic oak leaves.
Which Trees Turn Orange during Autumn? Maple trees are famous for producing bright orange leaves, including the sugar maple, Japanese maple, and red maple. Many oaks are not particularly impressive during the fall and have leaves that turn brown quickly.
What tree turns red orange in the fall?
Sugar maple
While commercially planted for its delicious syrup and value as lumber, this maple tree makes a great addition to any yard or park. And one of its most prominent features is amazing fall color. As the seasons change, the leaves turn vibrant shades of yellow, burnt orange and red.
The University of Illinois also notes that shingle oak and pin oak trees are a bit more abnormal than other oaks that display marcescence. These two species are some of the few who continue retaining leaves in the winter as mature trees.
Red oak varieties usually have pointed tips on their jagged leaves, as well as a smoother appearance to their bark. In contrast, a white oak's more bulbous leaf will be rounded at the tips, and the bark will have deep grooves, giving it a much more textured appearance.
The pin oak has great fall color, turning russet, bronze, and red.
White oak leaves are simple and arranged alternately on twigs. They are 7 to 9 lobed, 5 to 9 inches long with short petioles. The lobes are rounded without bristle tips and vary in length from leaf to leaf but are rather uniform on the same leaf. Surface color is dull green and paler below.
Red oak leaves are simple and arranged alternately on the twig. They are 7 to 11 lobed, and 5 to 9 inches long with slender petioles 1 to 2 inches long. The lobes are usually no longer than one third the total leaf width; the sinuses of the lobes are u-shaped and the tips of the lobes are bristle tipped.
The red color we see in the spring is made up of pigments called anthocyanins. These pigments come from an abundance of sugar that moves into the new leaves to give them energy to grow. The sugar gets converted into the red pigments or anthocyanins.
White oak trees get their name from the whitish color of the undersides of their leaves, distinguishing them from other oaks.
An underused beauty in midwestern yards and gardens, sweetgum has standout, star-shaped leaves that start out glossy green in summer, changing to glorious purple/red/multitones in fall. The colorful show endures longer than most trees.
Sweet gum (Liquidambar styraciflua) is often mistaken for a maple. The leaves have a similar shape, and the fall foliage color, well, that's bright and festive, just like a maple. Sweet gum leaves turn a mix of red, orange and yellow, often on the same tree.
What tree has red leaves all year?
Red maple is a fast growing deciduous trees with five pointed, palmate leaves, like in the symbol of Canada, and they are bright orange red in color all year round, from spring to fall.
Live Oak Leaf Drop – Live oak leaves start to turn yellow and blotchy in February or early March because they are senescing (or dying off). Then, they will fall off as the tree makes way for new leaves.
Leaf chlorosis (yellowing) is a perennial problem of pin oak (Quercus palustris) trees in landscapes in many parts of Michigan.
When you notice the leaves on red oaks taking on a yellowish tint when the veins in the leaves still look green, your tree may have iron chlorosis. You may even notice the edges of leaves turning brown with some premature leaf drop.
In a typical year, the first trees to change colors are maples and sugar maples which give us oranges and yellows, and of course the red maples. Later in the season, the oaks and hickories change. Regardless of how the drought affects fall foliage this year, autumn seldom disappoints here in New England.

Using neutral tones in fall color palettes
Design Tip: Purple can definitely be a fall color! Combining it with neutral tones adds depth to a fall color palette.
Fall is one of those themes, but other useful collections for those looking for a fall-like scheme include warm, vintage and gold.
Evergreen trees stay green year-round and never lose their foliage, even in the winter. Narrow-leafed evergreen trees with needles instead of wider leaves make up the majority of this category, but there are wide-leafed trees that are also evergreen. Deciduous trees lose their leaves in the fall.
There are a few species of trees that hold their dead leaves, Oaks, hornbeams, and Beech trees. This is a phenomenon called marcescence. Younger oaks may keep what looks like a full complement of dead brown leaves, while more mature oaks may keep them on just their lower branches.
What does it mean when an oak tree doesn't lose its leaves?
The term for this is “marcescence.” The abscission layer on these trees does not completely form until spring, which allows them to hold on to their leaves much longer. Marcescence almost always occurs on sexually immature parts of the tree (parts that have not yet formed flowers).
Species that generally change to a golden yellow in the fall include American elm, black cherry, cucumber magnolia, hop hornbeam, quaking aspen, shagbark hickory, striped maple, sugar maple, tulip poplar and witch hazel.
Most red oak leaves fade to shades of red to orange-red, and they hold their color longer than many deciduous trees. Some red oak trees have yellow fall foliage instead of red. While the color varies among trees, the leaves of individual trees tend to turn the same color every year.
Drought stress can make leaves wilt and turn yellow or brown. Here are some other symptoms of drought stress. Borer insects, like the two-lined chestnut borer, make leaves turn brown, wilt and eventually fall off. Root rot causes browning, starting at the top of the tree.
Every autumn we revel in the beauty of the fall colors. The mixture of red, purple, orange and yellow is the result of chemical processes that take place in the tree as the seasons change from summer to winter.

Why is my oak tree turning black?
Sooty Mold of Oak Trees
Sooty mold is a fungal disease spread to oak trees by aphids and scale insects; it causes black spots to appear on the live leaves. Over time, the black spots will spread to cover the entire leaf as the disease progresses and releases more spores into the surrounding atmosphere.
Bacterial leaf scorch can infect red oaks and other tree species. The disease rarely kills the tree, and it often shows symptoms each year, particularly in late summer. The disease is spread primarily by spittlebug and leaf hopper insects.
Oak Decline
Abiotic contributors include maturity, site factors, weather extremes including storm damage, extreme wet periods, and droughts. In residential settings, construction activity may cause root damage that weakens trees, causing them to become susceptible to a variety of biotic factors.
