What Are Suckers on Plants and How to Manage Them
What Are Suckers on Plants?
Suckers on plants are shoots that grow underground from the root or stem.
These shoots develop their own roots and eventually become new plants that are genetically identical to their parent plant.
Suckering can be either positive or negative, depending on the plant species.
However, suckers that emerge below the graft union should be promptly removed.
Some trees, like quaking aspens, primarily use suckering as a means of propagation.
Suckering can also indicate factors such as age, damage, disease, or weakening in trees.
To prevent the growth of additional plants or thickets, gardeners often remove suckers.
Key Points:
- Suckers are shoots that grow underground from the root or stem of a plant.
- These shoots develop their own roots and become genetically identical to the parent plant.
- Suckering can be positive or negative, depending on the plant species.
- Suckers emerging below the graft union should be promptly removed.

Did You Know?
1. Did you know that the “suckers” on plants, also known as adventitious shoots, are actually formed from the root system of the plant? These shoots emerge near the base of the plant and can give rise to new stems and branches.
2. In some cases, suckers can be quite invasive and can rapidly spread to form dense thickets. For example, the black cherry tree (Prunus serotina) is notorious for producing suckers that can quickly take over a garden or yard if not controlled.
3. Suckers often have a different leaf shape and appearance compared to the rest of the plant. This can help horticulturists and botanists identify specific species or varieties of plants, as leaf morphology can vary significantly between different sucker types.
4. Certain plants have evolved the ability to produce suckers as a response to stress or damage. If a plant is injured or its main stem is cut or removed, the production of suckers allows the plant to create new growth and ensure its survival.
5. Suckers are not unique to woody plants. Some herbaceous plants, such as strawberries, also produce suckers known as “runners.” These runners enable the plant to propagate vegetatively by producing new plants from the main parent plant, often resulting in the formation of a dense mat of interconnected plants.
Definition Of Plant Suckers
Plant suckers, also known as shoots, are growths that emerge from the underground root or stem of a plant. These shoots have the ability to put down their own roots and develop into new plants that are genetically identical to their parent. Suckering is a natural process that occurs in various plants and trees, serving different purposes depending on the species.
When a plant sucker emerges, it often appears as a small shoot or stem emerging from the base of the plant or at the surface of the soil near the parent plant. As the sucker grows, it develops its own root system and can eventually become a separate, independent plant.

- Plant suckers can develop into new plants that are genetically identical to their parent.
Positive And Negative Effects Of Suckering
The effects of suckering on plants can be both positive and negative. Suckering can be beneficial for plants that occupy large areas, such as shrubs or certain ground covers, as it allows them to spread and reproduce quickly. It enables these plants to fill in open spaces, preventing erosion and providing habitat for wildlife.
However, suckering can also have negative consequences, especially in garden or landscape settings. Some plants, like fruit trees and ornamental trees, tend to produce excessive suckers. This can lead to overcrowded or dense growth, resulting in competition for resources among the plants. Moreover, it may diminish the aesthetic appeal of the landscape or garden.
Why Suckers Below Graft Union Should Be Removed
In horticulture, grafting is a widely used technique to combine the desirable qualities of two different plants. The graft union occurs when the tissues of two plants are joined together, allowing them to grow as one plant.
When suckers emerge below the graft union, they originate from the rootstock rather than the grafted part of the plant.
Removing suckers below the graft union is essential to maintain the integrity of the grafted plant. If left unattended, these suckers can grow and dominate the growth of the desired plant, eventually overpowering it. This situation results in the rootstock taking over and the original grafted plant losing its distinctive characteristics.
Suckering As A Means Of Tree Propagation
Certain trees, such as quaking aspens, primarily propagate through suckering. This means that their main method of reproduction is through the emergence of suckers from the root system. Quaking aspens are known for their ability to form extensive clonal colonies, where numerous trees are genetically identical and interconnected underground by a shared root system.
Suckering in these trees is advantageous as it allows them to rapidly colonize an area and dominate the landscape. However, in garden or landscape settings, suckering can become problematic and challenging to manage if the trees are not properly controlled.
Some key points about suckering in certain trees:
- Suckering is the primary method of reproduction in trees like quaking aspens.
- Quaking aspens can form vast clonal colonies due to their suckering ability.
- The suckers emerge from the root system and are genetically identical to the parent tree.
- Suckering enables rapid colonization and landscape dominance.
- In garden or landscape settings, proper control measures are necessary to manage suckering.
Relationship Between Suckering And Tree Health
Suckering in trees is often an indicator of various factors that can affect their overall health. Suckers typically emerge in response to environmental stress, disease, damage, or the natural aging process of the tree. For instance, a tree that has suffered physical injury or has been pruned improperly may generate suckers as a survival mechanism to replace lost branches.
While suckering itself does not pose an inherent threat to the tree’s health, it is crucial to identify and address the underlying cause of the suckers. If the tree’s health is compromised, it is essential to investigate and remedy the root issue to ensure the well-being and longevity of the tree.
Understanding the nature of suckers in plants is vital for effective plant management. Suckering can have both positive and negative effects, depending on the specific plant and its environment. Removing suckers below a graft union is particularly important to preserve the desired characteristics of grafted plants. Furthermore, suckering plays a significant role in the propagation of certain trees. Observing suckering in trees can also provide valuable insights into their overall health and well-being. Through appropriate sucker management, gardeners and landscape enthusiasts can maintain the aesthetic appeal and health of their plants.

Frequently Asked Questions
How do you control plants?
Another way to control invasive plants is through biological control, which involves introducing natural enemies such as insects or pathogens to reduce their population. These enemies feed on or infect the targeted plants, limiting their growth and spread. By carefully selecting the appropriate method from these three categories, one can effectively control invasive plants and minimize their impact on the environment. It is important to consider factors such as the type of plant, the extent of invasion, and the desired outcome before implementing any control strategy.
1. How do suckers on plants affect the overall growth and health of the plant?
Suckers on plants can have a negative impact on the overall growth and health of the plant. Suckers are shoots that emerge from the base or lower parts of the plant, diverting energy and nutrients away from the main stem or desired branches. They compete for resources and can weaken the plant by draining its energy. This diversion of resources can lead to stunted growth, reduced flower or fruit production, and an overall decline in plant health. Therefore, it is important to remove suckers to ensure optimal growth and vigor of the plant.
2. What are the most effective methods for removing or limiting the growth of suckers on plants?
There are a few effective methods for removing or limiting the growth of suckers on plants. One approach is pruning. Regularly cutting off suckers close to the main stem can help prevent their growth. Additionally, it is important to properly dispose of sucker clippings to avoid any potential re-growth.
Another method is applying hormone-based sucker suppressants. These chemical treatments can be applied directly onto the suckers to inhibit their growth. However, it is essential to carefully follow the instructions and recommended dosage to prevent any damage to the plant or surrounding environment. Using a combination of pruning and suppressants can be the most effective way to control the growth of suckers on plants.
3. Are there any benefits or uses for suckers on plants, or are they purely detrimental to the plant’s development?
Suckers, also known as water sprouts or basal shoots, are young shoots that emerge from the base or roots of a plant. While suckers may seem detrimental to the plant’s development as they divert energy and resources away from the main growth, there are certain benefits and uses associated with them.
One potential benefit of suckers is their ability to provide a source of propagation for certain plants. Gardeners can detach suckers from the parent plant and replant them, allowing for easy and cost-effective propagation. Additionally, in some cases, suckers can serve as a backup if the main plant is damaged or dies, ensuring the survival of the species.
However, it is essential to note that the benefits of suckers vary depending on the plant species. In some plants, such as fruit trees, excessive sucker growth can negatively impact the overall health and productivity of the plant. Therefore, it is important to monitor and manage sucker growth accordingly to strike a balance between potential benefits and their impact on a plant’s development.
