White Flux or Alcoholic flux, is a stress-related disease that affects sweet gum, oak, elm and willow trees. The disease is caused by a microorganism that ferments the sap that seeps or bleeds from cracks and wounds in the bark. The result is a white, frothy ooze that has a fermenting odor similar to beer.
As you probably know, the yellow dust covering everything that doesn’t move this time every year is pine pollen. Pine trees produce large (very large) amounts of pollen each spring in order to ensure that the seeds get fertilized and the species can survive.
Pine trees produce male cones, which shed pollen, and female cones, which develop into pine cones. The eggs hatch and the pine catkin sawfly larvae feed on the male cones (or catkin) as they grow out. When they finish feeding, they drop to the ground to pupate.
That “black stuff” is the result of a bacterial infection called Wetwood or Slime Flux. These particular bacteria thrive in anaerobic (low oxygen) conditions present in the dense interior hardwood. As the anaerobic bacteria ferment and release carbon dioxide, it creates pressure forcing liquid from woods in the trunk.
White flux, also known as foamy canker or alcoholic flux, occurs when bacteria penetrate bark wounds or cracks and the underlying cambial tissue. The multiplying organisms ferment the sap, releasing alcohol and gasses.
Powdery mildew is a fungal pathogen that results in grayish or white growth with a powdery texture appearing on leaves, buds, fruit and branches. … Powdery mildew is rarely a serious disease, and vigorous established apple trees handle an infection without long-term damage.
The “tassels” that drop from oak trees are called catkins, and they are the spent male flowers whose purpose is to shed pollen that is carried by the wind to female flowers. If all goes well, the female flowers will then develop into the acorns that are the seeds of the oak tree.
Almost everyone who lives near oak trees has seen the small balls hanging in the tree branches, yet many still may ask: “What are oak galls?” Oak apple galls look like small, round fruit but they are actually plant deformities caused by oak apple gall wasps. The galls generally do not damage the oak tree host.
ANSWER: The live oaks are dropping male catkins. Their structures carry the male flowers of the trees. Live oaks, like many shade trees, produce separate male and female flowers on the same plant.
Essentially, catkins allow the tree to reproduce. Catkins allow the female flowers to be pollinated as the pollen from the male flowers is blown by the wind. Once the seeds have developed they are dispersed by the wind to avoid growing right below their parent.
There are about 90 species of oak in North America. All oaks produce acorns. Acorns belonging to trees in the red oak group take two growing seasons to mature; acorns in the white oak group mature in one season.
Samaras, also known as “helicopters” or “whirligigs.” Photo credit: J.S. … 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.
Trees With Spiked Seed Pods. If you’ve encountered some round, spiny balls under a tree or maybe still on the plant, and you’re wondering what it could be, it’s likely one of several options: buckeye/horsechestnut (Aesculus), chestnut (Castanea), or sweet gum (Liquidambar styraciflua).
The foul-smelling liquid can kill grass or other plants growing around the base of the tree. The slimy mess is not harmful to humans or pets, although the family dog might want to roll in it, making him less than welcome in the house.
We have received several questions this summer about trees that are covered with a black substance on their leaves and twigs. It almost looks like the leaves have been dusted with soot, and the black dust can be rubbed off with a finger. … In most cases, the problem is fungi called “sooty mold“.
Foam forms on the trunks of trees in heavy rains because of chemical interactions similar to those that occur when you make soap. … The air pollutants land on trees during dry periods and build up. During rains, they interact chemically, forming a soap and run down the trunks, foaming as it hits bumps in the bark.
Lichens are often found on tree trunks, branches and twigs as the bark provides a stable place to reside to collect needed sunlight, rainwater and materials from the air. They grow on healthy trees, as well as stressed or otherwise unhealthy ones.
It’s cottonwood, practicing its signature survival strategy. All that fluff you’ve seen in the air is a survival tactic for a tough species of tree.
The young mites move to the undersides of leaves where they feed and develop. Five or more generations of mites occur in summer, adult females spreading the infestation as they move to fresh leaves. The mites form fine silken webs on which they can be carried from tree to tree by wind.
Depending on the infecting fungi, some moldy core can turn into core rot, but this does not happen all of the time. If you encounter an eating apple that has moldy core and not core rot, the flesh is still eatable should you choose to eat around the core. … Consequently, these apples are perfectly fine and disease-free.
It’s easy to tell if your neighborhood is home to a cottonwood tree. The trees produce white seeds that look just like cotton. With the wind’s help, they can spread for miles, covering lawns, driveways and everything in sight with white fluff. At first glance, it may look like a snowstorm hit your yard!
The alder is also the only native deciduous tree to have tiny cones. Alder is monoecious, which means that both male and female flowers are found on the same tree. They take the form of catkins that appear in early spring, between February and April, usually before the leaves.
A catkin or ament is a slim, cylindrical flower cluster (a spike), with inconspicuous or no petals, usually wind-pollinated (anemophilous) but sometimes insect-pollinated (as in Salix). They contain many, usually unisexual flowers, arranged closely along a central stem that is often drooping.
Acorns are also rich in nutrients. Percentages vary from species to species, but all acorns contain large amounts of protein, carbohydrates and fats, as well as the minerals calcium, phosphorus and potassium, and the vitamin niacin.
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. These insects inject a hormone into the plant tissue, causing it to grow abnormally and enclose the developing wasp larvae.
When looking at an oak tree with small round balls hanging on the branches, you may have noticed it, much like acorns. These balls are known as galls and are not actually fruits. Galls are caused by parasitic insects and are actually growths.
The galls, or tumor-like growths, are produced by the tree in response to chemicals injected into it by an adult or larval gall-making insect. The shape of the gall is determined by the chemicals used by each species of gall-maker. Galls can be round and dense, woolly, fuzzy, veined, bullet-shaped or horned.
The oak tree pollen drop lasts about four days. It is this yellowish dust that is seen on car hoods and deck floors, and causes problems for people with seasonal allergies. Heavy rains and humid conditions may delay the release of pollen and affect the number of acorns produced on a single tree.
Live oaks bloom in spring, producing long catkins that drape gracefully from the ends of their branches. If your tree is shedding stringy stuff in spring, it might be engaging in its annual flowering where the long male catkins let loose pounds of yellow pollen and then fall from the tree as new leaves push them out.
The willow has a specialized flower called a catkin. A catkin is a cylindrical flower cluster with few to no petals. Catkins are found in some other tree species, such as birches, hickories and chestnuts. … During the spring, they are often mistaken for caterpillars once they have been pollinated and fallen off the tree.
Tiny flowers in long, slender, cylindrical clusters called catkins. … Male catkins appear in the last joints of twigs in summer and stand erect during winter. In the spring they flower, lengthening to 5–10 cm, and droop. Female catkins, 2–4 cm long, are solitary at the end of side branches and stand erect at maturity.
Catkins, the male flower of the hazelnut tree. It starts with catkins, a long droopy flower that first appear on hazelnuts in the spring. Catkins are the male parts of the tree that produce and release pollen. … The small red flower, or floret, receives the pollen and will later grow into a nut.
What is a mast year? This is a term that refers to a year that some trees and shrubs produce huge numbers of seeds as compared to other years.
Oak bark is the bark from several types of oak trees. It is used to make medicine. Oak bark is used as a tea for diarrhea, colds, fever, cough, and bronchitis; for stimulating appetite; and for improving digestion.
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.
Are Maple Seeds Edible? The helicopters, also called whirligigs but technically known as samaras, are the outer covering that must be removed when eating seeds from maple trees. The seed pods under the covering are edible. After peeling the outer covering of the samara, you’ll find a pod containing the seeds.
The fruits of maple trees (Acer spp.) are called samaras, but kids of all ages call them helicopters. Each seed has its own little “wings” that allow it to spiral downward and plant itself in the soil below. Maples aren’t the only species that produce samaras, but their helicopters fly best, by far.
The young spring leaves of maple are edible. You can eat them raw or cooked. … You can peel away the outside layer and eat the tiny seeds inside either raw or roasted. Soaking them in water first will take away some of the bitter taste.
The Sweet Gum tree is the sand spur of the forest. You painfully find them with your feet. The vicious seed pods have impaled many a forager and has done much to ruin the Sweet Gum’s reputation. … The only edible part of the tree is the dried sap which makes a fragrant, bitter chewing gum.
Not all species of sweetgum trees have balls. Some fruitless varieties of sweetgum trees, such as the sweetgum ‘Rotundiloba,’ don’t produce the seedpods. This means that there is no mess from these sweetgums and their flowers rarely mature into spiky gumballs.
