After a tsunami, soil often becomes saline and depleted of nutrients, making it challenging to grow plants. However, selecting the right species can help restore the soil and create a thriving outdoor plant box. Here are the best plants for post-tsunami soil:

1. Mangroves (Rhizophora spp.) – These salt-tolerant trees are ideal for coastal areas, as they stabilize soil and filter saltwater.

2. Sea Purslane (Sesuvium portulacastrum) – A hardy ground cover that thrives in saline conditions and prevents erosion.

3. Coconut Palm (Cocos nucifera) – Resilient and adaptable, coconut palms can grow in poor soil and provide shade.

4. Beach Morning Glory (Ipomoea pes-caprae) – This fast-growing vine helps bind sandy soil and tolerates salt spray.

5. Saltgrass (Distichlis spicata) – A tough grass that survives high salinity and improves soil structure.

For best results, mix compost or organic matter into the soil to boost fertility. Regular watering (with freshwater if possible) will also help leach excess salt. By choosing these resilient plants, you can transform a damaged landscape into a vibrant, sustainable garden.
