Green acorns on an oak are a common sight in summer. Typically, acorns “fall” around fall—in boom and bust cycles—to help plant new trees and to provide a nutritious food source for a number of critters.
- The acorn falls off the tree in late summer or early fall, and under the right conditions will germinate and grow into a new oak seedling. Like other deciduous trees that lose their leaves each fall, oaks go through a dormant period during the winter.

What is falling off my oak tree?
Notice “greenish brown things” falling from your live oak tree? The trees are dropping male catkins, which carry the male flowers of the tree. Use them as mulch or throw them in the compost when they start to pile up.
What are the black balls falling from oak trees?
If you have an oak tree in your home landscape, you might have spotted small, unsightly brown balls hanging like fruit or growing into a branch. These little balls, called oak galls, are a common occurrence caused when the tree reacts to non-stinging wasps laying their eggs on its leaves, branches, twigs or flowers.
What is the brown stuff falling from trees?
These stringy brown tassels are called catkins or tassels. They are the male pollen structures produced by oak trees (Quercus spp.). They hang in the trees like tassels on the end of bike handlebars, releasing their pollen into the wind to fertilize the female flowers.
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.
Should I remove oak galls?
Something you can do now – and I heartily recommend it – is to remove and destroy any galls you can find on the trees. There probably are many on twigs and branches; look for knobby and hard growth. Chances are it’s a gall. By removing it now, you lessen the number of eggs available to hatch come spring.
Are oak galls harmful to humans?
“Oak apple galls” are leaves that have developed into a thin sphere because wasps have laid eggs inside of the leaf. Inside the gall is a tiny wasp larva. Most galls, especially on leaves, do not hurt the oak tree, and the wasps aren’t harmful to people either.
Why are clumps of leaves falling off my oak tree?
A • You don’t say anything about the condition of the leaves, but if they are coming off in green bunches, then they are oaks that have either: (a) suffered minor twig damage from strong winds associated with recent storms; or (b) have squirrels in them that are building summer leaf nests.
Do oak trees have helicopters?
Oaks can often look like there are several trees growing from the same roots. and nest in oaks. Maples create seed pods, often referred to as “helicopters” because of their effect when falling to the ground in autumn.
What trees drop helicopters?
More commonly referred to as “helicopters,” “whirlers,” “twisters” or “whirligigs,” samaras are the winged seeds produced by maple trees. All maples produce samaras, but red, silver and Norway maples often produce the largest quantities.
Are oak trees male or female?
Function. Each oak tree is essentially both male and female, since it features both male and female flowers. The male flowers are small structures on stalk-like appendages called catkins; the catkins droop down from some of the branches. Female flowers are so small they are best identified with a magnifying glass.
What are the signs of a dying oak tree?
5 Signs that Your Oak Tree is Dying
- Yellow Leaves. Have you noticed yellow leaves with greenish-colored veins on your oak tree?
- Foliage Loss. Oak trees are bound to lose at least some of their foliage, especially when the cool fall and winter weather arrives.
- Decaying Bark.
- Powdery Mildew.
- Rotted Roots.
How do you treat a diseased oak tree?
All oaks, as well as many plants and vegetables, are prone to this infection. Treatment: In general, pruning dead twigs and branches during dormancy is the best treatment. For further protection, apply an appropriate fungicide to protect new growth.
How do I keep my oak tree healthy?
Here are our five top tips.
- Fertilizing. Fertilizer gives your live oak tree the nutrients to increase its capacity to capture sunlight so it can produce food and energy.
- Soil Cover. Covering the soil properly is the key to an oak’s survival.
- Never Tamper With a Live Oak Tree.
