Trees are not only a stunning addition to any landscape, but they also provide essential benefits like clean air, shade, and natural habitats for wildlife. However, trees can be vulnerable to a variety of pests and diseases that can compromise their health and lifespan.
Maintaining the wellbeing of your trees goes hand in hand with a vigilant approach to recognizing and addressing potential threats. Some of the most prevalent tree pests include aphids, scale insects, and bark beetles. These pests can cause extensive damage to trees, inhibiting growth, and even leading to tree death in severe cases. On the disease front, trees can fall prey to fungal, bacterial, or viral infections, leading to symptoms such as leaf spots, cankers, and root rot, all of which can deteriorate tree health and function.
Implementing a comprehensive tree protection plan is essential in maintaining a lush, thriving landscape and preserving the natural beauty and functionality of your trees. In this insightful guide, we’ll explore the common tree pests and diseases, discuss preventive measures, and share effective tree protection strategies to ensure your trees remain healthy and resilient.
Common Tree Pests and Diseases: Signs and Symptoms
One of the first steps in tree protection is becoming familiar with the common pests and diseases that may affect your trees. Here are some of the prevalent tree pests and diseases, along with the signs and symptoms associated with them.
1. Aphids: These tiny, sap-sucking insects can cause leaves to curl, wilt, and become discolored. They also produce honeydew, a sticky substance that encourages the growth of sooty mold on leaves and nearby surfaces.
2. Scale Insects: Scale insects feed on tree sap, leading to discolored and curled leaves, branch dieback, and, in some cases, tree death. Scales often appear as small, immobile bumps on leaves, stems, and branches of affected trees.
3. Bark Beetles: Bark beetles bore into the bark of trees, creating tunnels and potentially introducing harmful fungi. Signs of a bark beetle infestation may include entry and exit holes, sawdust-like frass, and tree decline, including yellowing foliage and branch dieback.
4. Leaf Spots: Fungal and bacterial leaf spots manifest as discolored, irregular spots on leaves, which can lead to premature leaf drop. If left untreated, these leaf spot diseases can weaken the tree and make it more susceptible to other diseases and pests.
5. Cankers: Cankers are localized dead areas on a tree’s bark, often surrounded by sunken or swollen tissue. They can be caused by various fungal and bacterial infections and may result in branch dieback or overall tree decline.
Preventive Measures for Tree Protection
Implementing preventive measures to maintain tree health is key in warding off pests and diseases. Here are some best practices to follow.
1. Proper Tree Selection: Plant tree species that are well-adapted to your region and the specific growing conditions of your landscape, thereby reducing their susceptibility to pests and diseases.
2. Practicing Good Hygiene: Keep the area surrounding your trees free from debris and fallen leaves, which can harbor pests and diseases. This also includes routine pruning to remove dead or diseased branches and improve airflow, reducing the likelihood of pests and diseases taking hold.
3. Adequate Irrigation and Mulching: Ensure your trees receive sufficient water and consider using mulch around the base to conserve moisture, regulate soil temperature, and minimize weed growth.
4. Careful Use of Pesticides: Use chemical control methods judiciously to prevent killing off beneficial insects that can help keep pest populations in check.
Effective Tree Protection Strategies
1. Cultural Controls
Cultural controls involve fostering a healthy growing environment for your trees. This includes proper planting techniques, providing adequate water and nutrients, and performing routine maintenance such as pruning and mulching. A dense canopy in trees susceptible to fungus disorders, such as crab apple, pear and some maples to name a few, should be trimmed by removing crowded interior branches to increase air flow. The increased airflow in the tree reduces the amount of time the leaves stay wet, which gives the fungus a smaller window to infect the tree. Overcrowding from other trees can also block out the light and stunt trees around them. Trimming crowded trees will allow them to better fit the area they are growing.
2. Trunk Injections
Trunk injections are a fantastic way to get the chemical to the source of the problem. We put the chemical into the vascular system of the tree where it travels directly to the issue correcting the problem from the inside. Pesticides, fungicides, fertilizer and specific nutrients will quickly correct most issues. The other benefit of a trunk injection is that it is 99% safe for the environment. Trunk injections are commonly used for correcting specific issues, or on trees that are too large or in an area that cannot be sprayed. They also do a fantastic job controlling needle cast in spruce trees.
3. Tree/Bush Spraying
Spraying is the tried and true method in our industry to control and correct most issues with trees and is one of the main methods we use to maintain a healthy and vibrant landscaping. Our maintenance blend consists of a pesticide, fungicide and miticide as needed. The spray is applied in the spring while the trees and insects are growing. Insects are controlled before they are able to cause damage and active spring mold spores are not able to attach themselves to the leaves. If you have a tree that was not treated in the spring and has an insect or fungal disorder a single sanitation spray can get your tree right back on the right track.
Everything we enjoy about our landscaping, the colors, shade, shape all comes from the roots. Without a healthy root system there is no healthy tree. Most of the subdivisions in our area had all the nutrient rich top soil scraped off during the development process, then dozers and graders compacted the soil. Debris from the roads and the building process little the dirt and can affect its PH. Homeowners are left with basically dead soil that is compacted and can’t hold water appropriate. Without fertilizers your plants don’t have a chance! Our fertilizers are so much more than just the low salt fertilizer we use. It also has a soil conditioner, mycorrhizae that attach to the root systems and increase water and nutrient uptake. The process of deep root feeding sprays the fertilizer as a liquid under high pressure 4-6 inches underground which de-compacts the soil. A spring and fall application are recommended.
