Landscape Installation in Southampton, NY
Free quotes for landscape installation in Southampton, NY.
Landscape installation in Southampton, NY is the build itself: grading, soil, trees, hedges, beds and lawn set into the ground in the right season, on soils and in weather that decide whether they take hold. The soil series common on Long Island, such as Plymouth and Carver, are excessively drained sands that run acid; salt spray reaches plantings near the bays and ocean; deer browse what Rutgers rates C or D; and the Suffolk County Water Authority sets the days new plants can be watered. We prepare the soil first, plant inside the spring and fall windows that NOAA's freeze dates mark, and leave every job with a watering plan. Most new planting is a capital improvement under New York's sales tax rules, and our estimate says which lines are.
Typical published range
$4.50 to $12 per square foot (Angi, updated September 2026, national)
Installation is priced by area or by project, and every published figure is national; no survey prices Long Island work. Angi's landscaping page, updated in September 2026, gives $4.50 to $12 a square foot, up to $40 for a tear-out and major remodel, a $3,517 average with most owners paying $1,248 to $6,069, and $15,000 to $50,000 for a full backyard renovation. Fixr, updated January 31, 2025, gives $5 to $20 a square foot and a $10,000 average for a 1/4-acre job with design, soil, grading, seed, plants, a patio and a walkway. LawnStarter's New York City row, $1,779 to $2,102 against $1,400 to $1,660 nationally, is a city figure, not a Southampton one. HomeGuide's February 2026 survey puts labor at $50 to $100 an hour for a two-person crew, and the Bureau of Labor Statistics gives landscaping and groundskeeping workers a national mean wage of $20.33 an hour in May 2025.
Unit prices show where the money goes. HomeGuide, dated February 4, 2026, gives $25 to $85 to plant a shrub, from $25 to $35 for a 1-foot plant to $65 to $85 for a 4-foot one; its tree page, dated July 8, 2024, gives $200 to $700 for a tree up to 10 feet, tree included, and $400 to $1,300 for a large one. Sales tax follows New York's Tax Bulletin TB-ST-505: planting shrubs, trees and perennials, a new lawn and retaining walls are capital improvements, and with your signed Form ST-124 the installer pays tax on materials and collects none from you. Annuals, freestanding fountains, replaced flagstones and small sections of sod are taxable, at 8.75 percent in Suffolk County under Publication 718. Removing shrubs or trees counts as a capital improvement only as part of another one. Published ranges for every service are on our Southampton landscaping cost page.
Soil preparation, loosening, testing and amending the ground before anything is planted, comes first on sand. Plymouth and Carver soils are excessively drained and acid; Riverhead and Haven soils, formed in glacial outwash, hold a loamy layer over stratified sand and gravel. We test pH before amending, since Cornell Cooperative Extension of Nassau County puts the range where nearly all turf nutrients are available at 6.0 to 7.0, and bigleaf hydrangea color follows the same chemistry: blue in acid soil, pink with lime. Hedges go in as specified, privet as small 15- to 30-inch plants about 18 inches apart, cut back by half at planting and kept out of poorly drained ground. Imported fill over 20 cubic yards on a Town of Southampton building permit must be clean fill (section 123-48A); in the Village of Southampton, moving topsoil within the same lot for landscaping needs no excavation permit, but hauling it off does.
Planting windows, the stretches of spring and fall when new plants go in, come from the freeze dates. NOAA's 1991-2020 normals for Bridgehampton put the median last spring freeze at April 23 and the first fall freeze at October 24; at Westhampton Gabreski Airport the dates are May 7 and October 14. The rules set the rest of the schedule. In the Village of Southampton, landscaping runs 8:00 a.m. to 6:00 p.m. on weekdays and 9:00 a.m. to 5:00 p.m. on Saturdays, never on Sundays or federal and state holidays. In the Town of Southampton, land cleared under a land disturbance permit must be revegetated, with the certificate obtained within one year of completion. Suffolk County bans fertilizer on turf from November 1 to April 1 but exempts newly planted landscapes and new sod, and New York allows phosphorus on lawns only where a soil test shows the need or in a new lawn's first growing season.
The South Fork adds three pressures. Deer: Rutgers rates American arborvitae D and bigleaf and panicle hydrangeas C, plants it says need fencing or repellents. Salt: Cornell Cooperative Extension of Suffolk County warns that plants only moderately tolerant of salt spray may show tip dieback and reduced growth. Absence: 54.8 percent of Village of Southampton housing units are seasonal, recreational or occasional-use homes in the ACS 2020-2024 estimates, so a new planting may go weeks without an owner watching it. We hand every installation over with a watering plan and, where you want one, to our estate landscape maintenance crew for the first season. The plan itself comes from our landscape design process.
Signs a bed or screen should be replanted, not patched
Some failures are maintenance problems. Others mean the plant, the soil or the placement was wrong from the start, and the fix is a new installation rather than another season of care. These are the conditions we look for on a first walk of a South Fork property.
- A screen of American arborvitae has been browsed bare at deer height; Rutgers rates it D and advises fencing or repellents for plants in that class.
- Boxwood shows round dark leaf spots, black streaks on young stems and heavy leaf drop, the boxwood blight symptoms Cornell Cooperative Extension describes on Long Island.
- A bed holds border privet or another species New York prohibits under 6 NYCRR Part 575, so it cannot be bought or replanted as a replacement.
- New plants fail in the same bed year after year because water runs straight through excessively drained sand that was never amended.
- Evergreens facing the water brown at the tips where on-shore wind carries salt spray, the injury pattern Cornell Cooperative Extension of Suffolk County describes.
- Construction is finished and the ground around a new house, pool or terrace is bare graded fill waiting for its planting plan.
Planting windows set by NOAA's 1991-2020 freeze dates
NOAA's 1991-2020 climate normals give two stations near Southampton. At Bridgehampton the median last 32-degree freeze in spring falls on April 23 and the first in fall on October 24, a growing season of 182 days; the median last 28-degree hard freeze falls on April 8 and the first on November 5, a 209-day season. At Westhampton Gabreski Airport, farther west, the 32-degree dates are May 7 and October 14, a season of 160 days. These are 50 percent probability dates, so in half of years the freeze comes later in spring or earlier in fall, and USDA adds that its zone map cannot show frost pockets caused by small hills and valleys. We plant spring trees, shrubs and hedges after the last freeze date for the site and finish fall planting ahead of the first.
Other plantings keep their own windows. Suffolk County's Healthy Lawns program gives late August to late September as the period to seed lawns on Long Island and early August for tall fescue, and says Kentucky bluegrass can be broadcast in early spring while soil is below 50 degrees F. The state Department of Agriculture and Markets' pollinator habitat guidelines seed meadows from mid-April to late May after frost or from late October to early November before it. USDA NRCS gives October 15 to April 1 for planting dormant American beachgrass in the Mid-Atlantic, 12 to 24 inches apart.
Choosing plants for salt spray, deer and New York's invasive list
Plant choice is part of the installation contract, and three published lists guide it. For salt, Cornell Cooperative Extension of Suffolk County's list of salt-spray tolerant plants for eastern Long Island includes bayberry, beach plum, rugosa rose, inkberry, pitch pine, bearberry and both smooth and bigleaf hydrangea, with eastern red cedar, eastern arborvitae and red chokeberry rated moderately tolerant, and it warns that moderate plants may show tip dieback, foliar damage and reduced growth. For deer, Rutgers rates American holly, bayberry, common boxwood, pitch pine and little bluestem A, rarely damaged; privet, inkberry and eastern red cedar B; bigleaf, oakleaf, panicle and smooth hydrangeas, Leyland cypress and western arborvitae C; American arborvitae D. Rutgers says no plant is deer-proof and that C and D plants need fencing or repellents.
For invasives, New York's 6 NYCRR Part 575 prohibits border privet, Japanese barberry apart from five exempt cultivars, multiflora rose, autumn olive and oriental bittersweet, and regulates burning bush and Norway maple, which may still be sold with a warning label but may not be knowingly introduced into a free-living state. California privet is not on the list. Boxwood carries one more risk: Cornell Cooperative Extension reports that boxwood blight struck Long Island landscapes in 2012, and lists pachysandra, including the native species, as a host, so we do not pair the two. Our deer-resistant native plantings page lists the natives by rating.
Establishment watering on the Water Authority's odd/even days
Establishment watering is the extra water a new planting needs until its roots grow out into the surrounding soil, and on the South Fork it has to fit the Suffolk County Water Authority's schedule. SCWA assigns odd calendar days to addresses ending in 1, 3, 5, 7 or 9 and even days to those ending in 0, 2, 4, 6 or 8, and asks for no watering from 10 a.m. to 4 p.m. In July 2026 SCWA declared a Stage 1 Water Alert for its customers in the Town of Southampton, making those limits rules, after heavy overnight and early-morning irrigation left storage tanks starting each day low; it rescinded the alert for the Town on July 31. Suffolk County's Healthy Lawns program advises watering between 4:00 and 8:00 a.m.
and, on sandy soil, smaller amounts more often, and says newly seeded areas should stay moist until the seed germinates. We put new beds on their own drip or spray zones so they can run longer than established ones, stagger start times, and check the output with the tuna-can test the county suggests. SCWA credits $150 for a smart controller and $75 for a rain sensor, up to $250 per account every three years, for devices bought on or after February 1, 2023. If chemicals are fed through the system, SCWA requires an RPZ backflow device, tested every year. Our irrigation systems page covers zones and backflow tests.
Plant in spring, in fall, or in phases
Most installations here fit one of two planting windows, and a large plan can use both. The choice turns on what is being planted, when you are in residence, and how much summer watering the site can count on under the Water Authority's schedule.
Spring planting after the last freeze
Planting starts after the median last freeze, April 23 at NOAA's Bridgehampton station and May 7 at Westhampton Gabreski Airport. Plants get a full growing season before winter, but they meet July, the driest month in the Bridgehampton normals at 3.16 inches, while watering is held to odd or even days. Spring suits owners who arrive for the season and can watch new plants.
Fall planting before the first freeze
Planting runs after the August heat and finishes ahead of the median first freeze, October 24 at Bridgehampton and October 14 at Westhampton Gabreski. Lawn seed fits the late-August to late-September period Suffolk County's Healthy Lawns program gives for Long Island. Because USDA notes that dry soil in late autumn can injure plants hardy in their zone, we keep fall plantings watered until the irrigation is closed.
A phased installation across both windows
On a large plan we build in phases: grading, drainage and trees in one window, hedges and beds in the next, lawn in late summer. Phasing spreads the cost across seasons and lets each planting settle before the next goes in. Each phase's new planting is a capital improvement under TB-ST-505, documented with Form ST-124.
Questions
Landscape Installation FAQs
How much does landscape installation cost per square foot?
National surveys put it at $4.50 to $12 (Angi, updated September 2026), $4 to $12 for basic work (HomeGuide, February 4, 2026), $4.50 to $14.50 (LawnStarter, April 20, 2026) and $5 to $20 (Fixr, January 31, 2025), with Angi reaching $40 for a tear-out. Fixr's own ends show why the spread is wide: about $3,000 for seed, topsoil and shrubs in a front yard, and $20,000 for design, soil and sod with a retaining wall, patio, gazebo and xeriscaping. No survey publishes a Long Island figure.
How much to landscape a 20x20 yard?
A 20 x 20 area is 400 square feet. Angi's September 2026 table has no row for that size, but it brackets one: a 200-square-foot area at $900 to $2,400 and 500 square feet at $2,250 to $6,000, national figures. If the 20 x 20 is a stone terrace rather than planting, Angi prices a bluestone patio that size at $6,400 to $10,000, and HomeGuide's December 19, 2025 survey prices a 20 x 20 stone patio at $6,400 to $14,000. No survey prices Long Island work.
Will arborvitae or Leyland cypress work as a screen here?
Both carry deer risk. Rutgers rates American arborvitae D, frequently severely damaged, and Leyland cypress and western arborvitae C. Penn State Extension calls 'Green Giant' arborvitae somewhat deer-resistant, and the U.S. National Arboretum calls it an excellent substitute for Leyland cypress, which University of Maryland Extension says suffers canker dieback when stressed by drought. On a deer-heavy lot we screen with plants Rutgers rates A or B, such as American holly, eastern red cedar or California privet, or we fence.
Do new plantings need a permit?
Usually the setting, not the planting, triggers one. In the Town of Southampton, fertilized planting within 200 feet of a wetland can need a Town wetlands permit, and clearing more than 2,000 square feet on a lot of 20,000 square feet or more needs a land disturbance permit. In the Village of Southampton, landscaping within 125 feet of a wetland needs a Village permit, and planting in the street right-of-way needs a written permit from the Superintendent of Public Works.
