Strategically placed garden plants offer a low-cost way to cool homes in summer Swati Mestri Scientific Editor Andrew Zinin Chief Editor Climate change is bringing extreme summer heat to many more countries, but using the right plants in your garden could…

Why it matters

As the fall planting season begins, this is a good time to plan for next summer.

Common ground

Planting now can also help your climbing plants and shrubs get established before spring.

Claim 1: “Leaving an air gap between the plant and the wall enhances heat insulation. Planting the shrub 0.5 meters (1.5 feet) from the wall or growing climbing plants on a wooden trellis set away from the wall is ideal for this.”
INSUFFICIENT EVIDENCE
No evidence was provided for this claim in the search results.

Claim 2: “plants that cool primarily through shade... have naturally large, dense canopies, such as cherry laurel and evergreen viburnums.”
CORROBORATED
Two independent web sources (one a general article on cooling homes and another a gardening/hedge site) confirm that cherry laurel and evergreen viburnums have dense canopies suitable for shade/privacy.

Claim 6: “Plants mitigate excess heat in three main ways. They create shade, reducing the sunlight absorbed by hard surfaces such as roads or driveways and then radiated back as infrared radiation (heat).”
SINGLE SOURCE
The provided evidence for this claim consists of irrelevant search results (adult content), except for one source in the evidence for claim 4 that mirrors the claim's wording. Since no independent corroborating sources were found in the specific evidence block for claim 0, it remains a single-source claim.
