Did you know? Laying mulch 75mm thick helps retain soil moisture and suppress weeds better than shallow layers. But why does that extra depth matter? Let’s break it down.
The Power of Mulch – More Than Just Looks
Mulch isn’t just about giving your garden that neat, finished look (although it does do that beautifully). It plays a vital role in soil health, plant protection, and long-term garden performance. Here’s how a 75mm mulch layer works wonders:
1. Moisture Retention
A 75mm (7.5cm) layer of mulch acts like a natural barrier between your soil and the sun. This significantly reduces evaporation, meaning your plants stay hydrated longer — and you water less often. Win-win!
2. Weed Suppression
Weeds thrive on light. A thicker mulch layer blocks sunlight from reaching weed seeds in the soil, reducing their ability to sprout. Say goodbye to those pesky invaders and hello to low-maintenance garden beds.
3. Soil Temperature Control
Mulch acts as an insulator. It keeps roots cooler during hot summer days and warmer during winter chills — protecting delicate plant roots year-round.
4. Soil Health Booster
Organic mulches break down over time, adding valuable nutrients to your soil. This improves soil structure, encourages microbial activity, and gives your plants a healthier foundation to grow.
