The City has more than 330,000 trees along its streets and strives to keep them healthy.
The City regularly prunes its trees according to their species, their age and, in some cases, the place where they are located. To do this, she resorts to the following techniques:
After being pruned, a tree can look quite bare. However, it will return to a more normal appearance during the following growing season, and it will have a shape and structure that will seem healthier and more aesthetic.
The City only prunes the trees that are on its land, in particular the section of the roadway belonging to it (road right-of-way) in front of and on the sides of residential lots and municipal parks.

Recently planted trees need to be watered frequently, as their roots are not yet established enough to be able to absorb enough water. It is therefore necessary to put water in the hole before planting and to water regularly afterwards.
During periods of drought, use a porous hose or conventional low-flow garden hose to carry out top-up watering. The best way to ensure that the water penetrates to the roots is to keep the watering ring or bowl around the tree. Place the garden hose in the earth and water for two hours twice a week. During a week when it rains for two days or more, it is not necessary to water.
It is best to water in the morning before the temperature warms up. If the water accumulates or drains elsewhere, it is because the flow is too high or the soil is saturated; then you should stop watering. Use a garden hose with a timer to make sure you don’t overwater.
A tree that was planted more than 15 years ago can survive without your help. Its roots can fetch the necessary water and trace elements even if the conditions on the surface seem very arid. Trees of all ages suffer the effects of long droughts. Trees planted in places where the conditions are not ideal, such as along sidewalks, near terraces or in raised lawns from which water flows naturally, will deteriorate quickly if they lack water. During periods of drought, regular watering can prevent insects and diseases.
When the weather is very dry, the soil particles keep the water molecules at a minimum level. Clay soils will really reduce in volume due to the loss of water, which decreases the ability of the soil to support adjacent structures such as foundations. Damage to the foundations caused by unstable clay soils can be avoided by ensuring that the trees located near the foundations are always well irrigated.
