Do your peach trees have some gummy looking sap exuding from the trunk? Gummosis is the term for the symptom of gummy sap oozing from the trunk and branches. It is not that unusual and can have several causes. Chemical, physical, insect, disease, or stress damage to the trunk can cause this symptom. Before you worry too much about it, you need to rule out the most destructive causes. There are two different peach borers that bore into trunks and scaffold branches that can cause this.

Peach Tree Leaking Sap

Pine resin. What do you think of when someone says resin? Images of sticky, gummy sap-like substances instantly jump to mind and most people consider all these plant products to be resins. Not all these sappy liquids are resins however. Resins are produced in special resin cells in plants, and are also produced when an injury occurs to the plant.

Resins can be produced through the bark of a tree, the flowers of an herb, or the buds of a shrub. Think of a pine tree that has a missing tree limb. What do you see? Carnivorous plants such as the spoon-leaved sundew Drosera intermedia use mucilage to trap insects.

Resins can occur as part of these other compounds, such as latex. Latex can contain resin, making the plant a resinous plant. There are many resinous plants all around the world. Although many resinous plants are not native to North America, some have established themselves here and are even considered weeds.

They can grow to feet tall with a diameter exceeding 40 inches. Because of their beauty and resistance to decay, tabonuco trees have been used for all types of furniture, cabinetwork, boat construction and boxes.

The smooth pale bark of tabonuco exudes a white resin that was used medicinally by early settlers and for making candles and incense. Tabonuco resin was also useful for making torches for starting fires and caulking material for boats. The endangered Puerto Rican parrot feeds on tabonuco seeds and the tree is rarely cut today. Humans have used resins and amber for thousands of years. An ant preserved in amber. Photo by Mila Zinkova. Amber is fossilized plant resin. Amber has been known to preserve insects and other small organisms that were imbedded in the resin before it hardened.

Amber is used for scientific research but it is used more widely for jewelry and art. It is often considered a gemstone although it is not a mineral.

Amber can be many colors, including green, gold, brown, red, black, and even bluish. The most well known and highly used amber comes from conifers, mostly pines; however, these same trees are not in existence today. Different amber sources have been dated from 40, years ago to million years ago. Amber can be found in deposits over many parts of the globe, generally in river deltas or sedimentary soils where water had washed plants downstream.

The remaining plant structures, including their resin, fossilized and created amber. European amber trade first began in the Stone Age, yet amber had been used ornamentally for hundreds of years before that. The best known amber deposit is from the Baltic Sea in north-central and Eastern Europe. From there, amber trade routes went to the Black Sea and the Mediterranean Sea and beyond.

Amber artifacts have been found in China from Myanmar deposits and Central America. Many cultures valued amber as religiously significant, due to its warm tones and ability to preserve life such as insects and plant parts. Other cultures used it to bargain for metal and necessities. Today, amber is still valued for its aesthetic beauty.

Balsam, cedar, and fir needle incense. Photo by Teresa Prendusi. Traditionally, incense was derived from plant resins, commonly from frankincense and myrrh trees. Resin is tapped from the tree and allowed to harden. When it is burned, the hardened resin releases aromatic smoke. Incense was a valuable commodity. Trade routes began from the southern coast of Arabia to the Mediterranean and Mesopotamia regions, beginning c.

Eventually, the trade routes collapsed because of better shipping routes, the loss of incense trees to agriculture, the demand for wood, and a decrease of rainfall in the region.

Other parts of the world, such as Central America, used resins for incense as well, although from plants native to those areas.

Both the Maya and the Aztec used resin from the copal tree as incense. Today, incense is made of other plant materials, in addition to resin, such as leaves, bark, seeds, fruits, roots, and rhizomes.

Ship builders have used the liquid form of resin for thousands of years.

It was used to waterproof rope and tarps, and was made into tar or pitch to seal the seams of wooden ships. The British Empire used resin for its navy, originally buying it from the Baltic region. However, they had to find a new source of resin, of which the American Colonies had plenty, due to the abundance of pine trees. Because of the demand and use of pines for resin, the first conservation legislation in America was passed in Massachusetts, requiring permits to cut or de-bark pines.

As sources of resin disappeared along the east coast, manufacturers looked elsewhere in America for resin sources. After the Revolutionary War, Britain went back to the Baltic for its resin stores while the new United States stored its own resin for pitch and tar.

Since the pine forests of the Southern United States were exhausted, and resin collection by tapping trees was getting too expensive, manufacturers started using mechanical means of refining wood by-products to collect resin. Developing countries around the world still use traditional methods for as long as their sources last.

Resin was also used to make turpentine and rosin. Turpentine was traditionally used in paints, but is now used in the chemical industry as a base to produce solvents, cleaners, fragrances, dry cleaning, and insecticides. It is also used in artificial flavors such as lemon, peppermint, and nutmeg, as well as cosmetics.

Rosin was discarded as a waste product until after the Civil War. It was used then as laundry soap but now as a variety of unrelated industrial products, such as adhesives, printing inks, and chewing gum. Varnish is plant resin combined with a solvent and drying oil also derived from plants to make it easier to apply to surfaces. It is commonly used for wood finishing and other crafts to provide protection and a glossy finish.

Natural lacquer is simply liquid resin. It is not mixed with any other solvents. Today, lacquer is a mixture of resin and quick-drying solvents; although in the United States, the name is used for a synthetic product.

Do you have sap dripping from trees? If so, you may be wondering how to stop a tree from dripping sap. Many homeowners have trouble with sap dripping off of their trees onto their cars and walkways. This sticky substance can be difficult to remove, accumulate dirt, and attract flies and other annoying insects. The sticky liquid oozing from the trees is Honeydew, and despite the name it has no relation to the fruit. Honeydew is the excrement of plant-sucking insects such as aphids , lace bugs , cicadas , and certain types of scale. Deciduous trees do not drip sap from their leaves. Insect infestations that lead to honeydew are frequently found on rose, ash, oak, elm, maple, willow, and fruit trees. Many homeowners ask specifically about their oak tree dripping sap.

Peach Diseases

The branch with the dead needles will have a canker which is a swollen area with discolored and cracked bark. Cankers on the main trunk are oval or diamond-shaped and often have a dead branch in the center. Sticky, clear-to-white sap oozes from the canker and drips from the infected branch or runs down the trunk. In spring, white-to-yellow blisters form at the edge of the canker and release powdery orange spores. Angular, yellow leaf spots that are contained by leaf veins can be seen on the upper leaf surface.

Tree Borer & Beetle Treatment

If you have apricot trees, or even one apricot tree, chances are that you have made a special effort to grow a special crop. Apricot tree diseases can undo years of work in just a few days, but most apricot tree diseases are identifiable, treatable, and sometimes preventable. Here is what you need to know about the most common apricot tree diseases. A frequent cause of this kind of apricot decline is armillaria root rot, which is also known as oak root fungus. Apricot trees affected with this disease show a general decline in vigor a year or two before the whole tree collapses. Usually there will be a circular area in an orchard where every tree is affected as the fungus spreads. The fungus spreads along the roots of infected trees to healthy trees. Peaches can also get armillaria root rot.

Insect Quick Links Anthracnose, Spot Description Anthracnose is a very common disease that attacks a very wide range of plants and trees. When Spot Anthracnose initially emerges, small light brown spots of dead tissue emerge on the leaves and blossoms in the late spring and summer. The spots develop during the cool, wet humid spring weather. The disease is caused by a fungus that over-winters on the bark of the tree or on fallen leaves.

Common Citrus Problems

If you can grow peach trees in your climate, consider yourself lucky. However, there are a few things you should know about common peach tree diseases and pests. Beautiful, fragrant flowers in the spring, followed by sweet, luscious fruit in the summer: just two of the joys of growing a peach tree. These popular stone fruits can be grown in USDA Zones 5 through 8, but they're happiest in the moderate temperatures of Zones 6 and 7. Plant your peach tree in a sunny spot with loamy, well-drained soil, and keep it well watered, fertilized, and pruned to encourage the largest harvests. While most need or more hours of chill, there are a few varieties that do well with as little as chill hours. Here are some of the most common peach issues you may face.
