Pine trees turning brown due to many reasons. Here, learn all about how to identify different causes and their preventions to stop pine trees from turning brown.
Are you wondering how to cure your pine tree that is going brown in your yard? Numerous factors might cause pine trees to become brown. The trees occasionally lose their leaves and appear to be dying. The needles can sometimes become brown and fall off.
Various factors contribute to the browning needles of a pine tree or the tree itself turning brown, including the stem.
Reviving a brown pine tree to become its lush green self is complex, and if it is utterly brown to the core, then there is no hope. However, the pine tree can survive if the problem is correctly identified and diagnosed beforehand.
Let’s look at the possible issues that cause the pine tree to turn brown and (Causes + Fixes) or better prevent them.
Pine Trees Turning Brown: Causes and How To Fix Them
1 Corm
The pine trees turn brown for several reasons. The leaves will remain on the pine tree for quite a time unless they fall off because the rings or branches are not clipped.
This is referred to as a “corm,” and it will regenerate. This issue won’t exist in trees with bigger branches and more leaves.
The tree will turn brown due to the wooden rings and the decomposition of the tree; however, tiny branches and small trees have less impact from this.
To start, ask yourself when did you last move the soil? Before taking action, several gardeners let the trees rest on the ground for extended periods.
The normal soil conditions of the tree are altered as a result, which explains why dark stains occasionally show up.
It is recommended to relocate the pine tree to a location with less rainfall if brown hues have emerged on the trunk.
Before trying to repair the tree, one must ensure that there isn’t any issue with the soil because it might get muddy or even toxic once the rains end.
- The tree’s top inspection comes next. It’s possible that a plant with an old canopy that is going brown was injured by a cyclone or rotted, which led it to collapse.
- Examine the trunk, paying close attention to the area at the bottom and the ends. Due to weak or broken trunks, improper tree support, or both, the branches might seem slightly twisted.
- The growth of algae, bacteria, fungi, or insects can also darken the top. It is wise to have the limb trimmed by a tree trimming business if the brown patches are clustered close to the tree’s stem or crown.
- Some trees do not respond to any treatment once they have started to turn brown. Despite any treatment, certain trees, mainly pines, can turn brown.
These kinds of trees comprise Picea deodara and Pinus sylvestris. These trees might appear ailing, but that doesn’t guarantee they won’t perish.
You should still take action immediately if the tree turns brown. However, keep in mind that until a tree is in immediate danger of collapsing, the best method to prevent it from withering is to leave it alone.

2 Environmental Factors that Lead to Pine Trees Turning Brown
To help with treatment, you must first determine the reason for any browning or needle loss on the pine tree. Brown needles on a pine tree are often a sign of low moisture or a cold environment.
Browning leaves on pine trees outdoors are typically an indication of either wet roots or that they are too parched due to a drought.
One should be capable of identifying the source of the problem according to the local weather. One should improve drainage at the tree’s base if the roots remain wet.
Try hydrating the pine tree once a week if there is a dryness to determine whether things get better.
3 Pine Trees Turning Brown Due to Old Age
Understanding that browning and dropping needles may be routine features for a pine tree’s growth cycle is crucial.
Depending on the type, pines normally lose their elder leaves in the fall after they have been on the branch for 2 to 5 years.
Every year, fresh blades grow to replace the old ones. However, you might want to investigate other potential causes if the tree loses its leaves at varying times of the year or if whole branches are going brown.
4 Fungi In Pine Trees
Different fungi that attack pine trees cause different kinds of needle blight. Each class experiences the sickness differently, but it typically involves browning needles.
For instance, Dothistroma needle blight frequently affects Austrian pines. Usually, in the summer, the damaged trees begin to sprout brown needles only on the bottom of the pine.
Contrarily, brown stains on the leaves can appear anyplace on the tree at any time during the year. It’s crucial first to pinpoint the fungus that has infected your pine tree.
The land, the wind, the precipitation, and sometimes even infected trimming tools can transmit an infection.
We’ll describe how to spot and treat the condition to reduce damage if you suspect a pine tree could have a fungal infection.
5 Annosus Root Rot
Annosus fungal disease limits the growth of the needles and results in “butt decay,” a rotting condition. This fungal infestation is an issue in pine plantation areas that have been thinned.
Following weakening, the newly cut trunks aid in the condition’s propagation. Even though this illness is fatal, there is a way to stop this from expanding to good pine trees. It starts with a significant stump rot.
The butt and roots start to decay softly. The fungi may produce conks and fruiting bodies at the trunk’s base.
The fruiting bodies are distinct in form and vary in color from gray-brown to dark brown on top, with white beneath.
For recently cut stumps, the fungus Heterobasidion annosum propagates quickly. The fungus can spread from contaminated stumps to healthy plants having cut surfaces by wind or dripping rain.
The spores first touch down and afterward enter the wood, where they start an infestation.
Years may pass before an infestation reactivates and affects the pine tree’s growth. Robust trees can also become infected by trunks and trees having annosus root rot via their roots.
Application of regular borax powder to the grounds of recently removed stumps will assist stop the spread to nearby trees. Use a salt spreader to sprinkle the boron powder.
6 Cotton Root Decay
Other names for cotton decay include Texas root decay, Ozonium decay, and Phymatotrichum root rot. It is among the hardest fungal infections to manage and affects over 2,000 different plant types.
The host’s fronds initially show a mild yellow or tanning. Within three days, there is persistent withering, then extinction.
The fungus will kill shrubs and trees more gradually. Ring designs of decaying plants mark the damaged regions, which can grow larger as time passes.
The fungi Phymatotrichum omnivorum is responsible for cotton root disease. The fungus slowly spreads from crop to crop through the earth, encroaching on new areas.
This fungus can remain alive for several years in mud up to eight feet below the surface.
If the pine tree has the cotton fungal disease, it is possible to save it as long as the deterioration isn’t yet severe.
7 Blight on brown spots on needles
For coniferous tree seedlings, particularly Afghan pines cultivated in Christmas tree farms, brown spot needles blight is a significant issue.
Months after the infestation, signs start to appear, and under the right meteorological circumstances, they can spread quickly.
The pine leaves develop spherical gray-green patches in the autumn. The dots then grow larger and encircle the tips with skinny brown lines. Later, the needles decompose and drop off.
The pathogen Mycosphaerella dearnessii is responsible for brown blotch needle blight. In only damp conditions will it propagate.
The raindrops’ dashing action helps the spores quickly spread and contaminate significant portions of the tree. The infection can also be propagated by infected pruning equipment.
Between two and three years, contaminated tips are destroyed, and contagious spores are killed by planned and controlled fire scorching. The infection can also be controlled using expert fungicide applications.
FAQs
How can I prevent my pine tree leaves from browning?
Use the following procedure to stop the pine tree turn brown:
- Add two inches of biomass or cow dung to a crest of soil along the tree’s chute.
- Sprinkle sulfur and ammonium sulfate over the dung
- Fill the basin with water until the bottom is 3 feet deep
- Maintain the soil’s moisture for a few weeks.
- Within the season, the tree will be green again.
- Planting a resilient crop all around the diseased area is yet another option. The infection is inhibited from spreading by the immune crop’s barrier.
