Beaches are naturally beautiful, and we can bring the beauty of this nature to our garden in a harmonious and sustainable way. But how?

Many individuals might think that creating and maintaining a garden at a beach house is challenging. Indeed, since we spend most of the year away from the coastline, the garden often remains neglected during this time.

Likewise, we don’t want to spend our vacation time gardening; on the contrary, we’re more inclined to admire nature and enjoy the flowers and fruits it provides.

Apart from being neglected throughout the year, the garden is exposed to typical coastal climate adversities. These include high summer temperatures, constant rain, wind, and salt spray, sandy and excessively saline soils, and even cold temperatures during winter.

All of these details need to be considered when planning a garden that should also feature flowers or fruits during the summer and require low maintenance. After all, there’s no point in planting a beautiful flower adapted to the coastal environment if it only blooms in winter when we’re not there to admire it.

Designing a seaside garden demands more from the landscaper, as beyond the factors listed above, the landscape must be harmonious and not clash with the natural beauty of the shoreline. It’s like conducting a complex orchestra that needs careful guidance to ensure everything works out and the residents are pleased.

A golden rule in such cases: closely observe the plants that naturally occur in the area; they are adapted and equipped to withstand adversities, given that the coastal landscape in one region may differ from another.

Another crucial consideration is the terrain. Low-lying land can be invaded by high tides, which can damage the garden. If your property is seaside, elevating it slightly can be a solution to prevent this issue.

Most landscapers opt for tropical gardens to adorn coastal constructions. The plants in these gardens are the most suited to withstand the elements and blend well with the beach landscape. Alternatively, Mediterranean or contemporary style gardens can also be executed without issues.

It’s important for the plants not to obstruct the view of the sea; on the contrary, they should enhance and frame it harmoniously.

After proper analysis, the soil should be corrected in terms of pH and nutrients, so it can accommodate the new plants. Typically, due to their sandiness, they need to be conditioned with clay-rich soil and ample organic matter. Spare no effort or expense during this phase, as properly prepared soil can prevent future headaches; this step is challenging to rectify after the garden’s implementation.

Low-growing species that thrive on the dunes near the sea are an excellent choice as ground cover in a seaside garden.

Furniture and accessories are equally significant and should be ultra-resistant. One of the more economical and durable choices is polypropylene. The material is lightweight and washable, and some manufacturers even treat the furniture with a special resin that guards against UV radiation.

For more sophisticated options, use resilient woods like teak, which requires little maintenance and should always be protected with marine varnish. Steer clear of metals, as they rust with salt spray. Even stainless steel should only be used if adequately protected. Stay away from natural fibers like reed or rattan; nowadays, synthetic materials are available as substitutes.

Finally, don’t forget that you wouldn’t want to spend your summer toiling away in the garden. Use your creativity and knowledge to craft your private paradise—a place for rest and contemplation. Note: Reserve a special spot for a hammock or chaise lounge to admire the sea view.

In the sunny state of Florida, coastal landscaping takes on a unique character due to its tropical climate. The warm temperatures and occasional storms pose challenges for plant selection. Palms like Coconut Palms and Sabal Palms thrive here, while colorful flowering plants such as Bougainvillea and Hibiscus add vibrancy to the landscape. Dune restoration and salt-tolerant grasses like Sea Oats are crucial for stabilizing the sandy soil and preventing erosion along the coastline.

Miami, located on the southern tip of Florida, showcases lush and tropical coastal landscaping. Palm trees, such as Royal Palms and Foxtail Palms, create a signature look. Bromeliads, Crotons, and other colorful foliage plants thrive in the subtropical climate. Water features and poolside gardens are popular additions to Miami’s coastal landscapes.
