What are the best plants to prevent soil compaction in marble boxes?

Soil compaction is a common issue in marble boxes, restricting root growth and reducing water drainage. To combat this, choosing the right plants is essential. Here are the best plants to prevent soil compaction in marble boxes:

1. Lavender – Its deep roots help aerate the soil naturally.

2. Ornamental Grasses – Fibrous root systems break up compacted layers.

3. Sedum (Stonecrop) – Drought-tolerant with shallow roots that improve soil structure.

4. Thyme – Low-growing and spreads to prevent soil hardening.

5. Dwarf Shrubs (e.g., Boxwood) – Their roots create channels for better water flow.

These plants not only enhance soil health but also add aesthetic appeal to your marble box garden. Regular mulching and avoiding overwatering further prevent compaction. Happy gardening!
