Why Are My Tree and Plant Leaves Turning Black?

There are several potential factors that contribute to the blackening of tree leaves, including fungal diseases, bacterial infections, environmental factors, nutritional deficiencies, and pests.

Fungal Diseases That Cause Black Tree Leaves

Fungal diseases are among the most common culprits when it comes to black tree leaves. One such disease is black spot, which affects various tree species, including roses. Black spot is caused by the fungus Diplocarpon rosae and manifests as black spots on the leaves, eventually leading to their discoloration and defoliation. Another example is sooty mold, a fungal growth that develops on the sugary secretions left behind by sap-sucking insects. This mold covers the leaves in a black, powdery substance, inhibiting photosynthesis and ultimately causing leaf discoloration.

Bacterial Infections That Cause Black Tree Leaves

Bacterial infections can also cause tree leaves to turn black. One notorious example is fire blight, which affects a wide range of trees, including apple, pear, and ornamental varieties. Fire blight is caused by the bacterium Erwinia amylovora and leads to wilting, blackening, and curling of leaves. Another bacterial infection that results in black leaf symptoms is bacterial leaf scorch. This disease affects trees such as oak, elm, and maple, and causes leaf margins to turn black and crispy.

Environmental Factors That Cause Black Tree Leaves

Environmental factors play a significant role in leaf discoloration. Exposure to extreme temperatures, such as frost or scorching heat, can cause leaves to turn black. Additionally, excessive sunlight without adequate protection can lead to sunscald, resulting in blackened leaves. Air pollution, especially high levels of smog or chemical pollutants, can also contribute to leaf discoloration. It is important to consider these factors and provide appropriate care and protection for your trees.

Nutritional Deficiencies and Excesses That Cause Black Tree Leaves

Nutritional imbalances can lead to blackened leaves as well. Certain deficiencies, such as iron or magnesium, can cause chlorosis, a condition characterized by yellowing and eventual blackening of leaves. On the other hand, excessive levels of certain nutrients, such as nitrogen, can result in leaf burn and blackening. It is essential to maintain a balanced nutrient profile in the soil to prevent these issues and promote healthy leaf growth.

Pests and Insects That Cause Black Tree Leaves

Pest infestations can also cause tree leaves to turn black. Aphids, for instance, are tiny insects that feed on the sap of leaves, leaving behind a sticky residue known as honeydew. This honeydew attracts sooty mold, which blackens the leaves. Other pests, such as scale insects and spider mites, can also cause leaf discoloration and blackening through their feeding activities. Proper pest management techniques, including regular inspections and appropriate insecticides, can help prevent these issues.

Prevention and Treatment for Black Tree Leaves

Prevention is key when it comes to addressing black tree leaves. Regular maintenance practices with a certified arborist consultation are vital. Other practices such as proper watering, pruning, and fertilization, can help keep trees healthy and resilient. It is also crucial to address any signs of disease or pest infestation promptly. In the case of fungal diseases, having your local tree care specialist apply fungicides can aid in prevention and treatment. For bacterial infections, pruning and removing affected branches is often necessary to prevent further spread. Consulting with a certified arborist can provide valuable guidance in determining the best course of action.

Conclusion and Final Thoughts

While the sight of black tree leaves may initially raise concerns, understanding the underlying causes can help you take appropriate action to address the issue. Whether it be fungal diseases, bacterial infections, environmental factors, nutritional imbalances, or pest infestations, a proactive approach to tree care and maintenance is crucial. By implementing preventative measures and seeking professional advice from a certified arborist when needed, you can ensure the health and vitality of your trees for years to come.

Remember, a healthy tree not only enhances the beauty of your garden but also contributes to the overall well-being of our environment.

What is the green stuff growing on my trees?

Most of the time, in damp, shady areas you will spot a substance on the branches or trunk of a seemingly declining tree. This substance can be either lichen or moss.

What’s the difference between lichen and moss on trees?

Lichen

  • A combination of fungi and algae

  • Can be a range of colors including blue, green gray etc.

  • Appears in thin flaky patches

Moss

  • Always dark green

  • Coarse texture

Does moss or lichen harm my tree?

Lichen does not harm trees, though it might seem that way because they are usually found on declining specimen. Actually, lichen just tends to thrive on unhealthy trees because when they are under stress, there are usually less leaves and branches, allowing more light to shine on the trunk and creating the perfect environment for lichen to take over.

How can I get rid of moss or lichen on my trees?

There is no pressing need to rid the tree of moss or lichen as it does no harm to your trees and actually can be beneficial to the environment by providing a food source for many birds and other animals. However, if you would still like to get rid of it, a fungicide called copper sulfate can be applied by an ISA certified Arborist to kill it.

If you have moss or lichen on your trees, it is best to have them assessed properly by one of our ISA certified Arborists to rule out any potential tree disease, tree decay or pests that could be causing stress on the tree to begin with.

Why Is Topping Your Trees Deadly?

Sometimes, due to improper planting or planning, the trees we once loved outgrow them selves and become a problem. It may seem easiest to just chop them at the top to shorten them back down to a reasonable size. However, doing so could put your trees at major risk for decline.

Why is tree topping bad for my trees?

  • Improper pruning leaves the tree open for pests and decay to take over

  • It triggers response growth, a trees natural reaction to grow a large amount of smaller weaker branches in place of what was lost. This can be very unsightly and dangerous in heavy storms

  • The tree struggles to repair the large amount of leaves and branches lost, its main food source

Topping your trees can end up being much more costly than just removing them al together and replanting and specimen that fits your style.

If you have trees that have outgrown their space and need some recommendations on how to fix them, our Arborists in Monroe are always available at the link below!

Why Are My Shrubs Dying?

DSC_7743.jpg

Some of the most common types of shrubs to plant around suburban houses are azaleas, boxwoods and holly’s. But sometimes, due to a number of reasons, these shrubs don’t last long before turning brown and dying off little by little.

But what’s causing my shrubs to die?

Many factors come into play when determining cause for decline in shrubs.

Environmental factors. Georgia heat can be a lot to handle, especially for certain specimen who prefer partly shaded areas or thrive in cooler environments. Before planting your desired shrub, be sure to do some research on where and how you should plant it to ensure it isn’t getting too much or too little sun.

Pests/diseases. Small insects such as borers or different types of diseases can cause your shrubs to turn brown or die. Be sure to have your property inspected by a certified Arborist to be sure that those diseases or pests don’t spread to your other trees or plants.

Soil moisture. In summertime, your shrubs will need a little extra TLC. Especially when it comes to water. The most vital thing to your plants health is ensuring they are getting enough water in extreme heat temperatures. However, it is also possible to over water your shrubs and trees as well so it is important to establish a schedule that fits.

Fertilizer overload. This can be tricky because unless a soil test has been performed, the proper amount or type of fertilizer you may need can be a guessing game. By applying too much of the wrong type of fertilizer to your shrubs, you can actually burn your shrubs by increasing the salt levels in the soil.

How can I stop my shrubs from dying?

If your shrubs are suffering from something simple like leaf scorch or drought, getting them in a shaded area by replanting or putting another species nearby to provide them with more shade could do the trick. Establishing a proper watering schedule especially in extreme heat situations is important to keep them healthy and happy as well. But if you are concerned about diseases or pests that could have infected your shrubs, be sure to contact your local ISA certified Arborist to schedule a free consultation on your landscape!

Is My Sprinkler System Damaging My Trees?

IMG_0033.jpg

Irrigation systems are great for low maintenance landscaping. Essentially you just set it , forget it, and watch everything bloom. However, if these irrigation systems are not properly placed, they can cause a problem for your trees and plants.

In the strong Georgia heat, we rarely think of overwatering posing any threats to our gardens. In the heat of the summer especially, it is very important to provide a substantial amount of water to keep your trees, plants and grass thriving.

When you decide to have your sprinkler system installed its important to make sure the location is ideal. Too much water can do just as much harm as too little. Overwatering with trees can be a dangerous situation as excessive moisture provides a perfect breeding ground for pathogens and fungus to develop, essentially leading to the weakening of your trees. If you notice any fungus or mushrooms growing at the base or the trunks of your trees, call a certified Arborist as soon as possible to have your trees properly assessed for decline.

Some signs your plants/trees are getting too much water are:

  • root rot

  • bark falling off the trunk

  • trunk damage

  • saturated soils

  • fungus (mushrooms, etc.)

Some signs your plants/trees aren’t getting enough water are:

  • wilted or curling leaves

  • smaller leaves than normal

  • leaf drop

  • yellowing or burning of the leaves

After installation, walk around to different spots checking the soil after a run to ensure it is getting proper moisture. If the soil is heavily saturated you know your trees and plants are being overwatered and visa versa.

Is It Too Late To Prune My Trees In Georgia?

Tree pruning, among other tree maintenance techniques can determine the health, longevity and cosmetic look of your trees. Tree pruning, especially on larger specimen is best left to the professionals as improperly pruning your trees can do more damage than good.
