Living mulches are a fantastic way to improve soil health, retain moisture, and suppress weeds in outdoor plant boxes. These low-growing plants act as a natural ground cover, reducing the need for synthetic mulches and promoting a thriving ecosystem. Here are some of the best plants to use as living mulches:

1. Clover (Trifolium spp.) – A nitrogen-fixing plant that enriches the soil and attracts pollinators.

2. Creeping Thyme (Thymus serpyllum) – Drought-tolerant and aromatic, perfect for sunny spots.

3. Ajuga (Ajuga reptans) – Spreads quickly, providing dense coverage with vibrant foliage.

4. Strawberries (Fragaria spp.) – Dual-purpose as they produce fruit while covering the soil.

5. Sweet Woodruff (Galium odoratum) – Ideal for shady areas, with fragrant leaves and white flowers.

By incorporating these plants into your outdoor plant boxes, you’ll create a sustainable, low-maintenance garden that benefits both plants and soil. Choose varieties that suit your climate and sunlight conditions for the best results.
