Understanding Coastal Gardening Challenges

Before we dive into the list of best coastal plants, let’s take a moment to understand the unique challenges that come with gardening near the ocean:

• Sandy Soil: Coastal areas are often characterized by sandy soil that drains quickly, making it challenging for plants to retain moisture and nutrients.
• High Salt Content: The salt content in coastal soil can damage plant roots and leaves, leading to stunted growth and foliage burn.
• Strong Winds: Coastal regions are prone to strong winds that can dry out the soil and plants, making it difficult for them to withstand the harsh conditions.
• Periodic Flooding: Flooding from high tides or storms can saturate the soil with saltwater, leading to nutrient depletion and root rot in plants.

Despite these challenges, there are many plants that thrive in coastal environments due to their adaptability and resilience. Let’s take a closer look at some of the best coastal plants that you can grow in your seaside garden.
