Extreme summer heat can be devastating for your garden. When temperatures reach **40°C (104°F)**, many plants struggle to survive — leaves wilt, soil dries out quickly, and roots overheat. However, there’s a simple, low-cost trick that can keep your plants healthy, green, and thriving even in scorching weather: **mulching**.

### Why Mulching Protects Roots in High Heat
Mulching involves covering the soil around plants with organic or inorganic material such as straw, hay, wood chips, or shredded leaves. This layer acts as a natural shield, protecting the roots from excessive heat and moisture loss.
**Benefits of mulching in extreme temperatures:**
1. **Regulates soil temperature** – Keeps roots cooler during the day and warmer at night.
2. **Reduces evaporation** – Retains soil moisture, cutting down the need for frequent watering.
3. **Prevents soil erosion** – Protects the topsoil from wind and water damage.
4. **Suppresses weeds** – Stops weeds from stealing water and nutrients from your plants.

### How to Apply Mulch for Maximum Effect
**Materials you can use:**
– Straw or hay (great for vegetables)
– Shredded leaves or grass clippings
– Wood chips or bark for long-term beds
**Steps:**
1. Water the soil deeply before applying mulch.
2. Spread a **5–8 cm layer** around the base of the plant, keeping it a few centimeters away from the stem to prevent rot.
3. Replenish the mulch as it breaks down over time.
