Tree Health Care and Arborganix

Whether a particular issue’s come up with your trees – like insect damage a weak limb or a strange symptom – or you’d just like to see your trees look a little healthier, Arborwood can take care of it.

Tree problems are often misdiagnosed, mainly because many symptoms look very similar. Add to that the many abiotic tree diseases in the Golden Horseshoe that appear differently from species to species, as well as the multitude of insects. Each tree and problem has its own treatments and in order for us to achieve the best effect, we like to visit and assess the site with you.

Treatments can range from soil analysis to soil treatments both Arborganix™ soil enhancements with our Compost Tea Program or organic fertilizers specific to your tree needs. Some trees may need injections with our Arborjet™ system, which involves a direct injection into the trunk of the tree. Some trees will need a target spray with pesticides to ensure they are not defoliated or permanently damaged by insects. Finally, if needed, we can spray the foliage with our Arborganix™ Compost Tea program up to three times per year to promote healthy and sustainable urban forests.

Arborganix™ Compost Tea

Arborwood has the great distinction of being the biggest brewer of Compost Tea in Canada and possibly North America, brewing approximately 1800 litres per day. Arborganix™ is our own proprietary, trademarked blend of ingredients specific to the needs of trees, and Arborwood Tree Health Care professionals take a more holistic, natural and organic approach compared to conventional tree care. Our Arborists have been studying and promoting this natural way of soil and tree Health for over 10 years.

Arborganix™ is designed to enhance the microbiology in the soils and on the leaves, often depleted by harsh chemicals as well as tree and lawn care products. When the soil microbiology is in check, the PH and other important needs will be balanced. This is essential for tree health as it treats the “root” of the problem, not just the symptoms.

We blend a very specific amount of worm castings where the worms are fed a specific organic food to ensure beneficial fungal activity in their castings and the worm castings are then blended with a specific compost formula for trees and healthy soils. Combined, this gives us our base and then, depending on the application, specific foods are added for the desired microbiology and then it’s applied to your trees. We use two different application methods for maximum effect – soil injections and foliar sprays.

The Arborganix™ Health Care Programs

The Arborganix™ programs are designed to enhance the health and vigor of the tree and suppress insect and disease infestation. We use a guiding philosophy of CPR for trees [link to EA article] which promotes the conservation, preservation and restoration of your valuable woody landscapes.

Air Spading, Tree Health Care - Radial Trenching - Air Spade

Designed to access the sensitive areas of the tree root system and to improve the soil structure, nutrient levels and increase the microbial activity.

  • Excavate trenches with an AirSpade
  • Trenches extend beyond the drip line by 30% of radius
  • Trenches are not to extend into the interior 30% of the drip line radius
  • Remove all excavated soil.
  • Replace excavated soil with finished compost soil mixture.

The benefits of this encompass a wide range of issues pertaining to trees in the urban setting such as: Soil aeration, Radial trenching, Root collar excavation, Root damage investigation, Girdling Roots, Vertical mulching, Transplanting / bare rooting, Checking root structure before pruning, Soil compaction reduction, Locating roots for utility line installation.

Advantages of Excavating with AirSpade:

Air excavation has become a preferred method for digging on many jobs ranging from utility work to advanced tree care. Excavating with the AirSpade offers a number of advantages over conventional tools such as picks, shovels, and backhoes, including:

  • Two to three times faster than hand excavation.
  • Less worker fatigue than a pick or shovel.
  • Eliminates sharp metal edges as featured on picks, digging blades, or buckets.
  • Harmless to buried, solid objects such as utility lines, telecommunication cables, tree roots, hazardous waste containers, or military ordnance.
  • Excavates some rocky soils where a shovel is difficult to use.
  • Breaks soil into small particles that are ideal for re-compaction.
  • Powered by common, tow-behind air compressors.

Tree Health Care - Aeration/Vertical Mulching

Aerate and vertical mulch with non-invasive tree root excavation. Excavation to be 6-10cm diameter holes, 20 - 45 cm deep, approximately 60 cm apart in the soil within the canopy of the tree. dispose of old soils and replace with a compost solution to improve soil structure and nutrient levels as well as increase the microbial activity

Tree Health Care – Mulching

Using natural wood chips for soil coverage or compaction protection.
