What Are Tree Suckers and How to Control Them?
What Are Tree Suckers?
Tree suckers are miniature shoots that sprout at the bottom of a tree’s trunk when the tree is stressed.
They can stunt the growth of healthy roots and prolong the growth time of flowers or fruits.
Suckers often occur if the base of the stem fails in grafted trees, especially on smaller ornamental trees like crabapples or redbuds.
It is important to remove suckers and take action as soon as possible to prevent their negative effects on tree growth.
Key Points:
- Tree suckers are small shoots that grow at the base of a stressed tree’s trunk.
- They can hinder the growth of healthy roots and delay the development of flowers or fruits.
- Suckers are common in grafted trees, particularly ornamental ones like crabapples or redbuds.
- Prompt removal of suckers is crucial to prevent negative impacts on tree growth.
- Suckers can occur when the base of the stem fails in grafted trees.
- Taking action as soon as possible is necessary to prevent the negative effects of suckers.
Did You Know?
1. Tree suckers are not actually a type of plant, but rather small shoots that grow from the base or roots of a mature tree.
2. Some tree suckers can grow into full-sized trees if they are left unpruned and become established.
3. Tree suckers are often genetically identical to the parent tree, making them useful for propagating tree species through a process called vegetative reproduction.
4. The term “sucker” comes from the way these shoots draw nutrients and resources from the main tree, sometimes causing detriment to its growth.
5. Certain tree species, such as aspens, are particularly prone to producing tree suckers, allowing them to spread and form extensive colonies connected by a shared root system.
Definition Of Tree Suckers
Tree suckers are miniature shoots that sprout at the bottom of a tree’s trunk when the tree is under stress. These suckers are often the tree’s response to damage or other unfavorable conditions. They can emerge from the base of the trunk or even from the root system. Suckers are characterized by their vigorous growth, often surpassing the main tree in speed and size. They usually lack the strength and stability of the main trunk and can hamper the overall health and growth of the tree.
In appearance, suckers resemble small branches with leaves and sometimes even buds. They are often seen as clusters of shoots arising from the same spot. These shoots can grow rapidly, diverting valuable resources and energy from the main trunk and healthy branches. This can lead to an unbalanced distribution of growth and negatively impact the overall aesthetics and health of the tree.
Impact Of Suckers On Root Growth
One of the primary concerns associated with tree suckers is their detrimental effect on root growth. Suckers compete with the main tree for essential nutrients and water from the soil. Their vigorous growth often puts a strain on the tree’s root system, limiting the resources available to support healthy root development. As a result, the growth of the main tree’s roots can be stunted, leading to a weaker and less stable overall structure.
Furthermore, the presence of suckers can disrupt the natural distribution of root density. Instead of developing an extensive and well-balanced root system, the tree’s energy is diverted towards supporting the sucker growth. This can cause the main tree to become more susceptible to environmental stressors, such as drought or strong winds, due to the compromised root system.

Effects Of Suckers On Flowering And Fruiting
Suckers have a significant impact on the flowering and fruiting of trees. Competing with the main branches for sunlight and nutrients, suckers delay or diminish the tree’s ability to produce flowers and fruits. The resources that should be allocated to the development of flowers and fruits are diverted towards the sucker growth, resulting in a prolonged growth period or reduced yields.
In addition to diverting resources, the presence of suckers disrupts the natural balance of hormones within the tree. Hormones play a crucial role in regulating flowering and fruiting processes. When suckers grow vigorously, they can produce an excess of growth hormones, disrupting the tree’s natural flowering and fruiting cycles. This can lead to irregular or reduced fruit production and a decline in overall reproductive health.
Suckers In Grafted Trees: Causes And Consequences
Suckers commonly occur in grafted trees, particularly in smaller ornamental varieties like crabapples or redbuds. Grafting involves joining a scion (the top portion of one tree) with a rootstock (the bottom portion of another tree) to create a new tree. However, sometimes the base of the stem fails to integrate properly with the rootstock, resulting in suckers emerging from the rootstock instead of the desired scion.
When suckers develop in grafted trees, they are referred to as “rootstock suckers.” These suckers have different genetics from the scion and often exhibit different characteristics, growth habits, or even produce different types of flowers or fruits. The presence of rootstock suckers can significantly impact the intended appearance and traits of the grafted tree.
Rootstock suckers can have adverse effects on the overall health and growth of grafted trees. The growth of the suckers competes with the desired scion for resources and can hinder its growth and development. Additionally, the vigorous growth of suckers can create structural imbalances, increasing the tree’s vulnerability to breakage or uprooting.
Preventing And Managing Tree Suckers
To prevent and manage tree suckers, it is important to take prompt action. Regularly inspect trees for the emergence of suckers and remove them as soon as possible. When removing suckers, it is vital to cut them as close to the base as possible to prevent regrowth. It might be necessary to repeatedly remove suckers as they can often reemerge after pruning.
For grafted trees, proper care during the grafting process can help prevent the development of suckers. Ensuring a strong union between the scion and rootstock can minimize the risk of the stem failing and producing suckers. Additionally, regular maintenance, such as removing competing shoots from the rootstock, can help redirect resources towards the desired scion and discourage sucker growth.
Promoting the overall health and vigor of trees through proper watering, fertilization, and pruning practices can also help prevent the emergence of suckers. By providing adequate resources and minimizing stress, trees are less likely to produce suckers as a response to unfavorable conditions.
tree suckers can negatively impact the growth, stability, and aesthetics of trees. It is crucial to remove suckers and take preventive measures to minimize their occurrence. By understanding the causes and consequences of suckers, and implementing appropriate management strategies, trees can flourish without the hindrance of these unwanted shoots.

Frequently Asked Questions
What is an offshoot of a tree?
An offshoot of a tree refers to a new sprout or shoot that extends from the main trunk or branches. This natural occurrence represents the tree’s ability to branch out and grow in different directions. Metaphorically, the term offshoot can also be applied to describe any developing aspect or derivative that stems from a particular idea or concept. Just as a tree’s offshoots signify expansion and diversity, these figurative offshoots emerge as innovative and novel ideas that stem from a central source.
What is tree sprouting?
Tree sprouting refers to the fascinating response of trees to stress or trauma, wherein they generate upright shoots known as water sprouts and suckers. These distinct growths occur in specific areas of the tree. Water sprouts are shoots that emerge on the trunk or branches of a tree, while suckers originate from the roots or the base of the tree. When a tree undergoes stress or damage, these sprouts serve as its resilient and determined effort to recover and heal. They can often be seen as a sign of a tree’s vitality and ability to adapt to challenging circumstances.
What is it called when a tree grows out of a stump?
When a tree grows out of a stump, it is known as coppicing. This natural process of sprouting from the stumps is commonly employed in silviculture as a method to regenerate forests. Coppicing allows the stump of a felled tree to regrow, giving rise to new shoots and eventually, a new tree. This sustainable practice has been utilized for centuries as a way to rejuvenate woodlands and continue harvesting timber while promoting healthy forest ecosystems.
What is the meaning of offshoot?
An offshoot refers to something that branches out or emerges from an existing entity or main stem. It can be a new development, concept, or organization that is derived from a pre-existing one. In the context of a plant, an offshoot is a branch that grows from the main stem, extending its growth and reach. The term “offshoot” encapsulates the idea of expansion, diversification, and evolution, whether in the realm of ideas or the natural world.
