20. Using Wool as Garden Mulch
Wool mulch comes from natural sheep wool and helps retain moisture in your soil effectively. It creates a barrier that limits weed growth by blocking light and preventing seeds from sprouting.
As it slowly breaks down, wool mulch enriches your soil by releasing nitrogen, which benefits your plants over time. This makes it a practical choice if you want a natural solution that supports plant health while reducing weeds.
Applying wool mulch can also decrease the need for frequent watering since it holds water like a sponge and releases it gradually. It typically lasts up to two years, offering long-lasting protection without introducing chemicals.
