Yardwork: Shade trees and shrubs
Cost effective home cooling
Strategically plant shade trees and shrubs to help cool down your home
Planting trees and shrubs strategically around your property can significantly cool down your home on hot summer days. These natural elements provide shade, wind protection, improved air quality, and absorb rainwater that could otherwise contribute to localized flooding.
Mature trees can cool surrounding areas by 2 degrees Celsius to 4 degrees Celsius, which reduces the need for air conditioning. This not only cuts your energy costs but also reduces greenhouse gas emissions. In addition, trees and shrubs help intercept rainwater, reduce soil erosion, and manage stormwater runoff-critical benefits as climate change increases the frequency and intensity of storms.
Trees in urban areas also play a vital role in reducing the urban heat island effect. As Ontario faces more extreme heat days due to global warming, increasing tree canopy cover is one of the most effective ways to offset the impact.
What to look for
- Native species: These are adapted to local soil, rainfall, and temperature conditions, and require less maintenance.
- Deep-rooted species: Ideal for reducing erosion and improving stormwater infiltration.
- Diversity of plant types: Combining trees, shrubs, and ground cover improves habitat value and environmental function.
- Placement: Plant deciduous trees on the south and west sides of your home to provide summer shade and allow winter sun exposure. Evergreen trees to the north and northwest can serve as windbreaks in winter.
Things to consider
- Root and utility conflicts: Check for underground services and avoid planting directly under power lines or near foundations.
- Mature size: Ensure the selected species won't overcrowd structures or each other as they grow.
- Soil condition and drainage: Amend soil if needed and avoid planting in areas with poor drainage.
- Watering and care: Young trees and shrubs need consistent watering for the first few years to establish deep roots.
- Long-term commitment: Trees and shrubs provide long-term benefits, but also require occasional pruning and care.
Average cost
$50 to $300 per tree, depending on size and species.
$20 to $100 per shrub, plus soil preparation or mulch as needed.
