Why are the needles on my pine tree turning orange?
In early summer, the rust fungus produces spores on leaves of Laborador tea or leather leaf. If the wind blows these spores onto current year spruce needles and if the weather is wet and cool, the spruce needles become infected and turn yellow, orange or tan in July and August.
Why do pine trees bleed sap?
Excessive pine tree sap loss results from injuries like broken branches in a storm, or accidental cuts made by weed whackers. It can also result from borer insects who dig holes in the tree. If the sap is dripping from multiple holes in the trunk, it is likely borers.
Why are my white pine needles turning brown?
Researchers noted this year’s brown needles are a result of last year’s wet weather. When there is heavy rain during the growing season (May to July), the interior needles of white pine trees are infected with fungal spores as they develop new shoots.
How do you treat a stressed pine tree?
Remove the lower branches of a pine tree that are dead, dying or damaged. This helps reinvigorate the tree. Avoid cutting the limb flush with the trunk so the wound can heal properly. Remove the lower branches of a pine tree that are dead, dying or damaged.
Can a stressed tree recover?
Trees can sometimes lose all their leaves to drought and recover; sometimes not. If a tree is severely stressed and drops all of its leaves, it may be unable to produce enough photosynthates to properly harden off and survive the up-coming winter. My advice, especially at this time of year, is to wait and see.
What causes evergreen trees to turn red?
Needle Cast Disease This disease most often springs to life in wet, warm weather when the temperature ranges from 65 to 75 degrees Fahrenheit, with the fungal spores spreading easily through warm rain. It causes the needles of the spruce to take on a reddish-purple, brown or yellow tint before they fall from the tree.
Why do trees bleed red?

What is wrong with my white pine?
Root diseases and cankers are the most common fungal pathogens that attack the Eastern white pine. Root disease symptoms are characterized by overall poor growth, the tree becomes off-color, wilts and dies. Insects often act as vectors (transporters of the pathogen) for diseases.
How do you save a dying white pine?
Solution: Dead and dying wood is a magnet for diseases and pests, so it has to go. Prune as needed, cutting back to healthy branches. Use rubbing alcohol between cuts to disinfect your tools. Try to keep the tree’s natural shape, and avoid cutting the branches flush to the trunk, which may damage the bark.
How do trees respond to stress?
When trees experience a disturbance (like an insect chewing its leaves), their capacity to soak up carbon dioxide and therefore to grow is strongly reduced. Similarly, the ability of the trees to supply us with wood is decreased.
Do any pine trees turn red?
CUSTER — Many pockets of ponderosa pine trees are appearing red or brown on the landscape across the central and southern portions of the Black Hills National Forest.
Do pine trees turn red in fall?
Before dropping, these needles change color, sometimes impressively. The old needles of red pines, for instance, will turn a deep copper color before falling, while white pines and pitch pines take on a lighter, golden color. Changing conifer colors can also be the sign of total needle drop.
Why are the needles on my white pine turning brown?
Often, needle browning is the primary symptom that alerts homeowners and nursery growers of health problems. In Kentucky, brown needles on white pine are often caused by one of the following three conditions: white pine decline, white pine root decline (Procerum root rot), or Phytophthora root rot.

Why are the needles on my white pine tree turning yellow?
Eastern white pine (Pinus strobus) with yellowing and browning needles attributed to white pine decline. Photo Credit: Travis Cleveland.

But, needle drop in white pine trees can also be a sign of something more serious.
Should I be concerned about the browning of my pine needles?
There is really nothing to be concerned about. What is happening is commonly called inner needle drop or third year needle drop. In some species like white pine and arborvitae, this fall browning takes place rather suddenly. The older needles turn a bright gold-yellow and remain attached for about 7 to 10 days depending on the weather.
What kind of pine trees have spots on their needles?
Pine trees affected: Affected pine trees include, but are not limited to, Austrian, jack, red, Ponderosa, mugo, and Scots. Symptoms: The first sign of the disease occurs when small yellow-orange spots form on the needles. In spring, the spots develop white, spore-producing pustules called aecia.
Is it normal for white pine needles to drop?
White pine decline is different than seasonal needle drop that happens in the fall in response to shorter days and cooler temperatures. Illinois Extension Horticulture Educator Ken Johnson says while needle drop may be alarming, it is normal this time of year.
