As summer temperatures soar across Canada, your beautifully maintained landscape can quickly become stressed. Prolonged heat waves, drought conditions, and increased UV exposure all contribute to dry soil, wilted plants, and a fatigued lawn. To keep your property lush and vibrant, it’s essential to take proactive steps in heat protection.
Mulch: Nature’s Insulation Layer
Mulching is one of the most effective ways to conserve soil moisture and regulate temperature. During hot summer months, exposed soil can dry out rapidly, leading to plant dehydration and poor root health. A generous layer of organic mulch — such as wood chips, shredded bark, or compost — acts like a protective barrier.
Mulch helps retain moisture by minimizing evaporation, suppresses weed growth that competes for water, and moderates soil temperature. This means roots stay cooler during the day and warmer at night, reducing heat shock. Replenish your mulch regularly, aiming for a 2–4 inch layer around trees, shrubs, and flower beds. Be careful not to mound mulch directly against plant stems or trunks, as this can lead to rot.
Water Deeply and Less Frequently
When it comes to watering during the summer, frequency matters less than depth. Shallow watering encourages surface-level root growth, which makes plants more vulnerable to heat and drought. Instead, adopt a deep-watering approach: saturate the soil down to at least 6 inches to promote deeper, more resilient root systems.
The best time to water is early in the morning, before the sun has reached its peak. This reduces water loss from evaporation and allows moisture to reach the roots effectively. For optimal results, use drip irrigation or soaker hoses rather than overhead sprinklers, as these methods deliver water directly to the base of plants while minimizing waste.
You can also consult your province’s water conservation guidelines — for example, Environment and Climate Change Canada provides resources for sustainable lawn care and climate adaptation strategies.
Choose Heat-Tolerant and Native Plants
A key strategy in building a resilient landscape is selecting plants that are naturally adapted to local climate conditions. Native plants and heat-tolerant varieties require less water, are more pest-resistant, and tend to thrive with minimal intervention.
For example, prairie grasses like Little Bluestem and drought-tolerant perennials such as Coneflower, Black-Eyed Susan, and Blanketflower perform exceptionally well in hot, dry conditions. For ground cover, creeping thyme or sedum varieties are low-maintenance and heat-resistant. When designing your garden, group plants with similar water needs together to improve efficiency.
This approach not only conserves water but also enhances biodiversity and attracts pollinators such as bees and butterflies, further supporting a healthy ecosystem in your backyard.
Maintain a Healthy Lawn with Smart Practices
Lawns are especially vulnerable during extreme heat. Without proper care, grass can quickly turn brown, thin out, and become susceptible to pests and disease. One of the best defences is setting your mower to a higher setting. Taller grass shades the soil, reduces evaporation, and develops deeper roots.
Avoid fertilizing during peak heat, as this can stress grass further and promote weak, rapid growth. Instead, focus on improving soil quality through aeration and topdressing in the spring or fall. For heat-stressed lawns, spot watering and limiting foot traffic can also reduce damage.
