Trees in Winnipeg can’t live on sun and water alone. For them to grow to their best health, they need air, water and nutrients. Various treatments can be a source of needed nutrients for weak or stressed trees, as well as a way to defend against pests and tree diseases. Kildonan Tree Service offers a variety of treatment services that can help the growth of your trees.


Though it may seem like an afterthought with the sunny weather and large amounts of precipitation we get in Winnipeg, trees needs extra nutrients to flourish. In landscaped environments, it’s impossible for nature’s cycle of food renewal to effectively take place. Research shows that using tree fertilizer regularly provides dramatic benefits including:

  • Greater resistance to disease
  • Increased vigor
  • Denser more luxurious foliage
  • Healthier, stronger root systems

At Kildonan Tree Service, our commercial grade fertilizer is the best fertilizer for trees and shrubs. It is enhanced with organic nitrogen and is pressure injected where it helps to feed the tree roots. It contains no chloride or nitrates and is good for the environment. A good time to apply tree fertilizer in most Northern temperate climates is fall or spring. This is when tree roots take the nutrients from the soil and apply them to important health-promoting functions. If you’d like to know more about having your trees fertilized contact one of our tree experts today.


In addition to ash trees, deciduous trees such as oak, elm, poplar and maple can become infected with diseases. Initially, fungus affects the leaves and then may spread throughout the tree. Fungus on Winnipeg trees may be inevitable, but it doesn’t have to kill your greenery. Kildonan Tree Service uses a fungicide that is environmentally friendly, along with the latest tools and application methods to prevent Dutch Elm Disease.

Despite all the care you give to your trees, there are still insects that can cause damage and wreak havoc on your landscaping. Insecticides may seem intimidating, but Kildonan Tree Service’s expert arborist staff will work on your trees with the upmost care. We use a biological spray that is safe for the environment. We can treat for cankerworms and forest tent caterpillars. We also have specialized equipment that allows us to reach more than 90 feet high, hitting the tops of nearly any tree in Winnipeg.

Left unchecked, insects and tree diseases can quickly damage your tree. An arborist’s keen eye is essential, and proactive monitoring goes a long way towards early detection. To learn more about treatments for trees in Winnipeg, use our online form to contact Kildonan Tree Service.
