Tree suckers can be a persistent nuisance for Calgary homeowners. These vigorous shoots emerge from the base or roots of a tree and can detract from its appearance, compete for nutrients, and lead to structural issues. Understanding why tree suckers appear and how to manage them effectively is crucial for maintaining healthy and beautiful trees. At Evergreen LTD, our ISA Certified Arborists offer expert advice and services to help you tackle this common problem.
Why Tree Suckers Exist
Biological Mechanisms: Tree suckers are part of a tree's natural survival strategy. They often emerge from dormant buds on roots or the lower trunk. Several factors can trigger their growth:
Stress Response: Trees under stress due to injury, disease, or adverse environmental conditions may produce suckers as a survival mechanism. These suckers can help the tree photosynthesize more efficiently and compensate for lost foliage.
Genetic Predisposition: Some tree species are more prone to sucker production due to their genetic makeup. Trees like willows, poplars, and certain fruit trees such as cherries are notorious for producing suckers.
Rootstock Vigour: In grafted trees, suckers often arise from the rootstock rather than the scion. The rootstock may be more vigorous and genetically predisposed to producing suckers.
Why Tree Suckers are Annoying
Aesthetic and Practical Concerns:
Aesthetic Impact: Suckers can ruin the aesthetic appeal of a tree, leading to an untidy and unruly appearance. This is especially problematic in ornamental landscapes where tree form and structure are important.
Competition for Resources: Suckers compete with the main tree for water, nutrients, and light. This competition can weaken the overall health of the tree and reduce its growth and vigor.
Structural Problems: Suckers can lead to structural issues if they are allowed to grow unchecked. They create dense, bushy growth at the base of the tree, which can interfere with mowing and other landscape maintenance activities.
Root Damage: In some cases, suckers can emerge from roots near the soil surface, causing damage to nearby infrastructure like sidewalks and driveways.
Management and Control of Tree Suckers
Preventive Measures:
Proper Tree Care: Maintaining tree health through proper watering, fertilization, and pruning can reduce the likelihood of sucker formation. Healthy trees are less likely to produce suckers as a stress response.
Mulching: Applying mulch around the base of the tree helps retain moisture, regulate soil temperature, and reduce the likelihood of suckers emerging from surface roots. In Calgary, you can find quality mulch at local garden centers like Greengate Garden Centres and Blue Grass Nursery & Garden Centre.
Mechanical Control:
Regular Pruning: Pruning suckers as soon as they appear is crucial. Using sharp pruning shears, suckers should be cut close to the point of origin. Regular monitoring and prompt removal can prevent suckers from becoming a persistent problem. Evergreen LTD offers professional pruning services to ensure your trees remain healthy and well-maintained.
Root Pruning: In severe cases, root pruning may be necessary. This involves cutting back roots that are producing suckers. It should be done with caution to avoid damaging the tree. Our arborists are trained to perform root pruning safely and effectively.
Chemical Control:
Herbicides: Applying systemic herbicides to suckers can be effective. Herbicides should be applied directly to the sucker foliage to avoid damaging the main tree. It is important to follow manufacturer instructions and safety guidelines when using chemical controls.
Sucker Growth Inhibitors: Products specifically designed to inhibit sucker growth can be applied to the base of the tree. These inhibitors reduce the frequency and vigor of sucker production.
The Importance of Managing Tree Suckers for Healthy Trees
Tree suckers are a common and often frustrating issue for homeowners. Understanding the biological reasons for their emergence and the problems they cause is essential for effective management. By implementing a combination of proper tree care, mechanical removal, and, when necessary, chemical controls, you can maintain healthy, aesthetically pleasing trees and minimize the nuisance of tree suckers.
