Does Mulching Really Help in Hot Weather?
When the mercury rises and rain seems like a distant memory, mulching can actually be a lifesaver for your garden. Here’s how mulch protects your garden in the heat:
Moisture Retention: Mulch slows evaporation, meaning your plants need less frequent watering.
Temperature Regulation within the Soil: Providing a layer of insulation helps keep roots cool during heatwaves (and prevents them from freezing over winter).
Suppression of W**d Growth: Mulch blocks sunlight from reaching the soil, meaning fewer weeds and less competition for precious water.
Improvement in Soil Health: Organic mulches break down over time, enriching the soil.
Prevention of Soil Erosion: The protective barrier that mulch creates helps keep soil structure intact, even in dry, windy weather.
By reducing the stress plants experience in extreme heat, mulching helps them continue to grow, flower, and fruit well into summer.
