UNEQUALED IN THE
Tree Pruning for Sherwood Park & Edmonton
When it comes to tree pruning, Sherwood Park and Edmonton homeowners trust the experts at Arbor Man Tree Care. We’re locally owned, carry nearly 20 years of experience, and have ISA-Certified Arborist on staff. Since you’re here, you are most likely looking for someone to prune a tree or several trees on your property. And, more likely than not, the reason you are seeking a tree care service to perform your pruning is mostly for aesthetic enhancements — and that’s okay! But, did you know regular pruning also keeps trees healthy?
In natural forest settings, falling limbs help to dislodge weak and unhealthy limbs from other trees, as well as their own lower branches. Also, trees naturally cut off nutrients to under-productive branches through a process known as “self-pruning.” Although, the process can take years for the dying limb to fall away, creating a potential a hazard for property and people within the vicinity.
Thinning gives branches the room they need to mature and receive adequate sunlight. It also allows wind to pass more freely through the tree, reducing the risk of branches being broken during a storm or high winds. Proper pruning gives trees a huge health advantage, such as removing dead wood to allow wounds to fully heal. At some point, a rubbing branch will either die or become an entry point for insects, disease, and decay.
Our team will give your trees the professional, quality care they need to thrive and be healthy. For more information on tree pruning in Sherwood Park, Edmonton, and the surrounding areas, call Arbor Man Tree Care!
Keep Your Trees Free from Disease and Insects
Dibotryon morbosum or Apiosporina morbosa is a plant pathogen, which is the causal agent of black knot. It affects the cherry, plum, apricot and chokecherry trees of North America. Most commonly infecting chokecherry (Mayday and Shubert) in Alberta. The disease produces rough, black areas that encircle and kill the infested parts, and provide habitat for insects. Black Knot occurs only on the wood parts of trees, primarily on twigs and branches but can spread to larger limbs and even the trunk. Olive-green swellings from the disease are visible in the late spring, but as it spreads and matures typically by autumn rough black knots circle and kill affected parts.
Prune out infected parts 6 to 8 inches back from infection making sure not to cut through infected parts and thus spread the disease. Regular disinfection of pruning tools is highly recommended. This is best done when the tree is dormant.
Yellow Headed Spruce Sawfly
Yellow Headed Spruce Sawfly- (Pikonema alaskensis Rohwer), can cause serious economic and aesthetic loss to ornamental and commercially grown spruce. The feeding destruction of the needles can reduce plant growth and vigor up to two years after the damage occurs. The yellowheaded spruce sawfly “worm” is commonly misidentified as the spruce budworm. This is most likely because both insects are spring defoliators, but this is where the similarity ends. Yellowheaded spruce sawfly is a stingless wasp. It is a clean defoliator, leaving few partial needles in its wake, and will fed on new and old needles. Yellow headed spruce sawfly will rarely be found on all spruce trees in a planting.
Options include: Hand picking, especially when numbers are small; High pressure blast of water; Insecticidal soap; Ace-Jet systemic insecticide is effective for control of this pest.
Spruce Budworm – being a messy eater, needles are seldom completely consumed by the larvae, but are often clipped at the base and webbed together. These dead needles persist on the trees for a few weeks giving trees a scorched appearance in mid-summer. When populations are low and moderate, partial loss of new foliage occurs, particularly in the upper portion of the tree. During severe persistent infestations, all of the new foliage plus some old foliage may be destroyed for several successive years. Buds and developing shoots may be killed in their formative stages. Complete tree mortality can occur following five to six years of severe infestation.
Recommended treatment Ace-Jet systemic insecticide is effective for control of this pest.
Bronze Birch Borer
BBB (Bronze Birch Borer) has become epidemic in Alberta. The adult is a copper/bronze colored slender beetle. The larvae, which do the damage, are unseen, feeding on the vascular tissue under the bark. The Bronze Birch Borer typically attacks trees which are already stressed or in decline. A birch infested with Bronze Birch Borer will start showing dieback in the crown, increasing in severity as the infestation continues, often leading to death of the tree. In later stages of infestation, the trunk will show D-shaped, rust-stained exit holes and may also have swollen extrusions under the bark where the tree tried to grow over larval galleries.
Recommended treatment Ace-Jet systemic insecticide is effective for control of this pest.
Treat Bronze Birch Borer with either TREE-äge or IMA-jet. The comparatively large vasculature in birch trees will readily move IMA-jet upward into the canopy. TREE-äge is more viscous and will take slightly longer to inject but will provide a longer residual effect. TREE-äge and IMA-jet will eliminate the Bronze Birch Borer larvae inside the tree. Independent studies strongly recommend that treatments be applied early, before extensive disruption occurs to the vascular tissues. Arborjet recommends treatment when Bronze Birch Borer is detected in your area, but trees still appear healthy for best outcomes (dieback symptoms on infested trees should be <40%). Applications should be made in the spring, about 30 days prior to expected adult emergence; however, treatment may be applied during the growing season (May – September) to protect trees. Uptake of formulation is fastest when trees are actively transpiring, after they have developed a full canopy. Bronze Birch Borer treatment in the spring will prevent the adult beetles from feeding and laying eggs in the tree, whereas summer treatment will kill the larval stage of Bronze Birch Borer feeding under the bark. Make summer treatment applications in the morning when temperatures are moderate. If soil is dry, water trees prior to treatment. Injection in the fall (after leaves color but before they fall) can protect the tree for the following season.
Tree Injections in Edmonton
Arbor Man uses the ArborJet systemic injection system. Although trunk injection is new to Canada, it’s known as a fast and effective disease control method in the USA, where it has been used for decades. Systemics are considered much more environmentally friendly than spraying, since systemic insecticides (we use IMA-Jet) are high pressure – injected into the wood (i.e., the xylem tissue). This keeps the chemicals away from the air and surfaces including humans and pets. Systemics protect the whole tree and can reach some pests that spraying can’t reach, such as wood borers and leaf rollers & miners. In fact, at this time, systemics are the only hope of saving a tree infected with poplar borers. Systemic injection prices vary according to site distance, tree diameters and number of trees. Injections are much cheaper than the cost of tree removal and/or re-landscaping and are sometimes be the only alternative.
A few small holes are drilled in the base of the tree, the formulation is injected and then the Arborplug is placed to seal the holes. Bark will grow completely over the Arborplug within 1-2 years. Formulations injected into the trunk reach the branches, stems, leaves and even the roots. Some insecticide formulations will protect trees for multiple years with a single injection.
Fruit Trees – Apple, Crab Apple, Pear, Mountain Ash, Cotoneaster Shrubs, Raspberry and Saskatoon
The most damaging disease affecting plants in the rose family is FIRE BLIGHT (Erwinia amylovora). Diseased leaves appear red and fire scorched (hence the name) Leaves turn brown, die and wilt downwards often creating a shepheards crook affect. Second stage is indicated by bark cankers where the bark splits, becomes indented and can result in the death of the tree
A combination of pruning out diseased portions and chemical control using (BACASTAT TM) to protect against further infection. Annual systemic injection is recommended.
Scab infections on leaves start as olive green to brown spots with an irregular or feathered edge. As leaf infections grow, they may merge together and assume a dark brown velvety appearance. Severely infected leaves may turn yellow and drop prematurely. Scab infections on young fruit start out as olive green to brown spots. As the lesions enlarge, they harden, and eventually become black, corky, inedible areas on the fruit. Severely infected fruit may be deformed and often crack open.
A trunk injection with a systemic fungicide PHOSPHO-jet is recommended. PHOSPHO-jet inhibits fungal cells while eliciting a plant health response from the tree. It promotes stronger, tree cells, root development, and triggers the tree’s natural defense mechanisms making it more resistant to infection with quicker recovery time.
