When choosing trees to plant in your garden or orchard, it is very important to consider their resistance to pests and ants. This will help keep your landscape healthy and attractive for years to come.
It's important to make that choice because the damage that diseases and pests cause to plants is sometimes irreversible. That way, those trees will grow healthier and stronger. They will have a very fundamental role in environmental conservation.
This article will explain how to choose trees with natural resistance to pests and ants, as well as some of the benefits of choosing these types of trees.
Difference between being pest resistant or tolerant
Some trees have the ability to resist pests and diseases because they have developed defense mechanisms against natural enemies.
Let's keep in mind that being pest resistant or pest tolerant is a key difference. that we need to know when choosing the type of tree.
Plants have natural defense systems that help combat diseases and pests. These defenses include physical barriers and chemical responses that make them harmful to pests.
Pest-resistant plants They have a mechanism that prevents damage. For example, they can release chemicals into the roots to repel pests and ants.
In the case of being tolerant to pests and diseases means that it resists damage caused by pests and survives symptoms that can include leaf loss without losing its performance.
We must also know that these defenses are important because some resistant plants release chemicals that repel pests, but attract predators that are beneficial.
Characteristics of trees with natural resistance
Strong, healthy trees are more resistant to pest infestations and other stressors. Look for trees with strong root systems, uniform growth, and well-developed leaves and stems.
Trees that turn yellow or wither may be of compromised health and should be avoided.
These are the characteristics of trees with the greatest natural resistance to diseases and pests:
Some trees produce substances that are toxic to certain insects, for example, essential oils and tannins.
They have a thick or textured bark which make it difficult for pests to lay eggs or feed.
Its leaves have textures, smells or compounds may be less palatable to insects.
They present vigorous growth which can help the tree overcome minor damage caused by pests.
One thing to keep in mind is that native trees tend to have greater resistance to the local pests they have evolved with.
Most of these tree species can attract beneficial insects that feed on pests.
Pest-resistant trees
Some of the most common pest-resistant trees are pine, oak, cedar, juniper, and walnut. Their resin can also act as a barrier and repellent.
Citrus fruits (lemon, orange, mandarin): The essential oils in its leaves and bark can repel some pests.
Cypress: Its resinous wood and aroma act as a natural repellent for certain insects.
Eucalyptus: Its leaves contain strong oils that repel many pests.
Neem tree: Known for its powerful natural insecticidal properties, it is an evergreen tree native to India, ideal for providing excellent shade thanks to its thick foliage. Its unique feature is its Sanskrit name, which means "healer of all ills."
Some species of maples: Certain varieties have moderate resistance to some common pests.
Lavender (bush): Although it is not a tree, its strong aroma repels many pests and can be an excellent companion plant.
When looking for pest-resistant trees, it is important to choose varieties that require relatively low maintenance and are somewhat resistant to disease and temperature changes.
Tips to maintain stamina
- Proper watering: A stressed tree is more susceptible to pests.
- Healthy soil: A nutrient-rich soil strengthens the tree.
- Proper pruning: To improve air circulation and remove weak branches.
- Regular observation: Detect problems early.
- Encourage the presence of beneficial insects: Ladybugs, lacewings, etc.
Choosing native species
It's also important to know the native tree species when looking for those with natural resistance to pests and ants.
Native trees are more likely to be naturally resistant to pests and local diseases, since these have been part of the ecosystem for long periods of time.
Native species occur naturally and are adapted to local climate, soil, and water conditions. They also help sustain local wildlife by providing food and shelter.
Examine the tree
Once you have selected a tree species that is known to have some resistance to insects and other pests, It is important to examine the actual tree.
Look for signs of pests and diseases to make sure it's healthy. Trees with pests or diseases may be more susceptible to future infestations.
Isolated, damaged, or deformed trees may be more susceptible to pests and diseases. Avoid these types of trees whenever possible.
Avoid the use of chemical pesticides
Even if you select trees that are naturally pest-resistant, it is important to avoid using chemical pesticides.
Chemical pesticides can kill beneficial insects, harm wildlife, contaminate nearby water sources, and cause health problems for humans.
It is better to use natural methods to control annoying pests and avoid the use of chemical pesticides whenever possible.
Benefits of choosing trees with natural pest resistance
There are many benefits to choosing pest-resistant trees. These trees are often easier to maintain and require less effort when it comes to pest control.
Naturally hardy trees tend to be more vigorous and require less water and fertilizer to grow. They also provide a home and food for local wildlife, and can help improve the health of the local ecosystem.
Finally, when choosing trees for landscaping, it's important to consider their resistance to pests and ants. Therefore, It is better to plant native species.
First, examine the tree, choose resistant trees, and avoid using chemical pesticides. These factors will help you choose the best trees for your landscape, which will require less maintenance and provide numerous benefits for your garden and the ecosystem.
