How To Landscape Around A Pool

Planning Your Pool Landscape: Where Design Meets Function

A well-designed pool landscape looks good, but it also works — keeping things safe, easy to care for, and visually unified. Before you pick out plants or pavers, take time to study your site: where the sun hits, which way the wind blows, how water drains, and how the pool sits in relation to your house. The American Society of Landscape Architects (ASLA) suggests thinking of the pool area like another room in your home — using similar ideas about flow, size, and proportion.

Most residential pool landscapes cover 1,500 to 4,000 square feet, including the deck, planting beds, and any built features like fire pits or storage. Working within that space means choosing plants and materials carefully, and keeping in mind how chlorine splash, reflected heat, and foot traffic will affect each part of the design.

Hardscape First: Building the Foundation

Landscape architects usually finish all hardscape work before adding plants. The deck around your pool sets the tone — and it needs to be slip-resistant, stay cool enough to walk on barefoot, and be simple to clean. Each material has trade-offs in cost and performance.

Material	Cost per sq ft (installed)	Heat Retention	Slip Resistance	Maintenance Level
Brushed Concrete	$6–$10	High	Good	Low
Travertine Pavers	$15–$30	Low–Moderate	Excellent	Moderate
Porcelain Tile	$18–$35	Moderate	Good (textured)	Low
Natural Flagstone	$20–$40	Moderate	Good	Moderate
Composite Decking	$12–$22	Low	Excellent	Low

Travertine shows up often in high-end residential projects — think Palm Beach, Florida or Scottsdale, Arizona — because its natural pores help it stay cooler. On a 95°F day, it can run 20–30°F cooler than standard concrete. That difference matters if you’re walking across it barefoot in summer.

Deck width matters too. Most local codes require at least 4 feet of clearance around the pool, but 8 to 12 feet gives you room for lounge chairs, paths, and a safety margin. Skimp on width, and furniture ends up in planting beds — making the space feel tight and harder to use safely.

Retaining Walls and Grade Changes

If your yard slopes, retaining walls help manage elevation changes and keep soil from washing into the pool. Dry-stacked natural stone walls between 18 and 36 inches tall hold up well and fit most pool styles. For walls taller than 36 inches, most areas require engineered drawings and permits. You’ll pay about $25–$50 per square face foot for professionally installed natural stone, or $15–$25 per square face foot for segmental concrete block systems.

Pergolas, Shade Structures, and Outdoor Rooms

A pool without shade feels incomplete. The University of Florida's Institute of Food and Agricultural Sciences (UF/IFAS) points out that UV exposure near water is stronger than on open grass — so shade isn’t just nice to have, it’s practical. Cedar or pressure-treated pine pergolas for a 12×16 foot area typically cost $3,000–$8,000 installed. Aluminum or steel versions range from $5,000 to $15,000 depending on size and detail. Placing a pergola on the west or southwest side blocks harsh afternoon sun while still letting morning light hit the water.

Plant Selection: Balancing Beauty and Practicality

Plants near pools need to handle reflected heat, occasional chlorine or saltwater splash, and the compacted, amended soils common after construction. They should also drop little — leaves, seeds, or berries clog filters and make wet decks slippery. That cuts down your options, but plenty of good ones remain.

Trees and Large Shrubs

Keep trees with aggressive surface roots at least 15 feet from the pool shell. Poplars (Populus spp.), willows (Salix spp.), and weeping figs (Ficus benjamina) are known to crack decks and invade plumbing lines. Better choices include:

• Lagerstroemia indica (Crape Myrtle) — Upright shape, minimal root spread, blooms in summer in white, pink, or red. Grows 15–25 feet depending on cultivar. Handles heat well.
• Olea europaea (Olive) — Drought-tolerant, slow-growing, and sculptural. Fruitless types like 'Swan Hill' avoid mess. Hardy in USDA zones 8–11.
• Podocarpus macrophyllus (Yew Podocarpus) — Dense, columnar evergreen that works well for screening. Grows about 6–8 inches per year and holds up to pruning. Drops very little.
• Magnolia grandiflora 'Little Gem' — Compact version that reaches about 20 feet, with big white flowers and glossy leaves. Plant it at least 10 feet from the pool edge.

In tropical and subtropical climates, the Bismarck Palm (Bismarckia nobilis) stands out with its silver-blue fronds. At maturity it reaches 40–60 feet, but a single 10-foot specimen planted 12–15 feet from the pool adds height without shedding much. Installed cost runs $800–$1,500 depending on where you live.

Groundcovers and Perennials

Planting beds right next to the deck do best with low, dense plants that hold weeds down without constant trimming. Loose mulch tends to blow or wash onto the deck and into the pool, so groundcovers that knit together tightly are a better bet.

• Agapanthus africanus (Lily of the Nile) — Strap-like leaves and blue or white summer flowers. Clumping habit, drought-tolerant once settled in, and rarely bothered by pests.
• Liriope muscari (Lilyturf) — Evergreen, grows in sun or shade, spreads slowly to form a solid mat. Variegated types add visual interest.
• Rosmarinus officinalis (Rosemary) — Prostrate forms like 'Huntington Carpet' make fragrant, drought-tolerant groundcovers in warm areas. The scent may help keep some insects away.
• Festuca glauca (Blue Fescue) — Forms neat 6–10 inch mounds of blue-gray grass. Gives texture against stone or concrete.
• Trachelospermum jasminoides (Star Jasmine) — Evergreen vine or groundcover with sweet-smelling white flowers in spring. Grows 1–2 feet tall and handles heat well.

Lighting Design for Safety and Atmosphere

Pool lighting has two main jobs: keeping people safe and setting the mood. The National Electric Code (NEC) Article 680 covers all electrical work within 20 feet of a pool — requiring GFCI protection and fixtures rated for wet locations. Hire a licensed electrician for anything in or near the water.

For landscape lighting beyond the pool perimeter, low-voltage LED systems are reliable, energy-efficient, and flexible to install. A typical lighting plan for a 2,500 square foot pool landscape uses 12–20 fixtures and costs $1,500–$4,000 installed. Key spots to light include:

1. Paths and steps along all walking routes — aim for at least 0.5 foot-candles at ground level, per ASLA safety guidelines
2. Uplighting for standout trees and structural plants to add height and interest after dark
3. Deck perimeter lighting, using recessed or surface-mounted fixtures that sit flush with the hardscape
4. Underwater pool lighting, usually LED fixtures designed for submersion
5. Accent lights for water features, retaining walls, or pergola structures

The Illuminating Engineering Society (IES) advises keeping the brightness ratio between the brightest and darkest parts of your outdoor space no higher than 10:1. Big differences in light levels cause glare and make it hard for eyes to adjust — so layer several softer lights instead of relying on one bright fixture in an otherwise dark yard.

Water Features and Naturalistic Elements

Adding a secondary water feature — like a spillover spa, deck jet, bubbler, or freestanding fountain — extends the experience of your pool and helps drown out street or neighbor noise. A spillover spa at one end of the pool becomes a focal point and adds $8,000–$15,000 to the project, depending on size and finish.

For a more natural look, consider how places like Chicago’s Lurie Garden blend strong hardscape with loose, meadow-style planting. Apply that idea to your pool: let ornamental grasses and perennials soften the edges of the deck, but keep sightlines clear to the water so you can watch swimmers easily.

"The best pool landscapes feel inevitable — as though the pool has always been there and the plants grew up around it naturally. That quality comes from careful attention to scale, material continuity, and plant massing, not from expensive materials alone." — Adapted from ASLA Professional Practice guidelines on residential water feature design, 2022

Boulders and groupings of natural stone also lend a natural feel. Try boulders weighing 200–500 pounds, placed in groups of three or five (odd numbers look more organic), partially buried and surrounded by appropriate plants. Locally quarried stone usually costs less and reads as belonging to the area — a key idea in regionalist landscape design, championed by figures like Lawrence Halprin.

Maintenance Planning and Long-Term Sustainability

A pool landscape that looks great on day one but takes 10 hours a week to maintain isn’t working. Sustainable designs use plants with similar water and fertilizer needs, hardscape materials that age well without constant upkeep, and irrigation systems divided into zones that match those needs.

Drip irrigation beats spray systems near pools. Spray heads tend to wet the deck, creating slip hazards and encouraging algae. A well-planned drip system delivers water straight to plant roots and uses 30–50% less water than spray irrigation, according to a 2021 University of California Cooperative Extension study.

Fertilizer near pools needs caution. Nitrogen-heavy formulas that wash into the water speed up algae growth and throw off chemistry. Use slow-release granular fertilizers applied at least 6 feet from the pool edge, and don’t fertilize within 48 hours of expected rain. Organic options with lower soluble nitrogen work better for plants closest to the water.

Annual maintenance for a well-designed 2,500 square foot pool landscape usually runs $1,200–$3,000 for professional service — covering pruning, feeding, checking the irrigation system, and cleaning hardscapes. Landscapes planted with suitable species and mulched properly from the start tend to fall toward the lower end of that range as plants mature and fill in, cutting down on weeding and replacements.
