Watering wisely
One of the biggest challenges during a heatwave is ensuring your plants receive adequate water without the risk of evaporation.
Contrary to what might seem intuitive, watering your garden in the middle of the day can do more harm than good.
The intense midday sun can cause the water to evaporate quickly, leaving the soil dry and depriving plants of essential moisture.
Instead, water your plants generously in the early morning and late afternoon.
This timing allows the soil to retain moisture longer, providing your plants with the hydration they need to survive the heat.

The magic of mulch
Mulch is a gardener’s best friend during hot weather.
By acting as a protective barrier over the soil, mulch helps to shield the ground from direct sunlight and reduces evaporation rates after watering.
This means your plants can absorb more water over a longer period, minimising the need for frequent watering.
Dry grass clippings are an excellent choice for mulch during a heatwave.
They are easy to obtain and effectively protect the soil with their sturdy exterior.
Shading potted plants
Potted plants have the advantage of mobility.
During extreme heat, consider moving them to shaded areas of your garden.
This not only prevents them from overheating but also makes it easier to manage their watering needs.
Creating natural shade
For plants that are fixed in place, creating shade can be a bit more challenging but not impossible.
Use larger plants, bushes, or ferns to provide natural cover for more delicate flowers and plants.
These larger plants can cast shadows and protect others from the direct sun, creating a more balanced and cooler environment.
Grass maintenance
While mowing the lawn might seem like a never-ending summer chore, it’s essential for maintaining a healthy garden.
Keep your grass at a length of three to five inches to ensure it can cast shadows over the soil, providing additional protection from the sun’s rays.
This length helps maintain a cooler soil temperature, benefiting the overall garden ecosystem.
