What to Plant First in New Jersey Landscaping Designs

Introduction: Start with the big picture

Designing a landscape in New Jersey requires a phased approach. Planting the wrong item first or tackling seasonal tasks in the wrong order can cause extra work, wasted money, and inferior long-term results. This article explains what to plant first, why sequence matters, and specific plant and maintenance recommendations tuned to New Jersey’s climatic and soil variability.

Understand New Jersey’s growing context

New Jersey stretches from the Hudson River to the Atlantic coast and from the Pine Barrens to the Highlands. That variety matters for plant selection and timing.

• USDA hardiness zones commonly range from about 6a in higher inland areas to 7b along the coast.
• Soils vary from acidic, sandy soils in the Pine Barrens to heavier loams and clays inland. Coastal sites may experience salt spray and strong winds.
• Deer pressure is a serious, unevenly distributed issue across the state; municipalities and neighborhoods differ.

Knowing your microclimate, sunlight patterns, soil texture and drainage, and pest pressures is the first practical step before choosing the initial plants.

Planting priority: what to put in the ground first

1. Site assessment, soil test, and design framework.
2. Trees and large structural shrubs (anchors).
3. Evergreen hedges and windbreaks where needed.
4. Hardscape, drainage improvements, and soil amendments.
5. Lawn or groundcover (if included).
6. Perennials, ornamental grasses, and native understory shrubs.
7. Bulbs.
8. Annuals and seasonal color.

Planting in this order saves time and reduces the risk of damaging smaller plantings while establishing large, long-lived elements first.

Why plant trees and large shrubs first?

Trees and large shrubs are the backbone of any landscape. Planting them first gives you:

• Immediate structure and scale for the rest of the design.
• Shade patterns that determine where sun-loving and shade-tolerant plants belong.
• Root systems that need room to establish; it’s easier to plant smaller items around them later than to replant large trees.
• Long-term habitat and value; trees take decades to mature and shape the site.

Planting trees and shrubs in the first year also allows you to focus on proper placement relative to utilities, property lines, and existing structures.

Best timing for major plantings in New Jersey

• Fall (mid-September through October) is ideal for planting trees and shrubs across most of New Jersey. Soil is still warm enough for root growth, air temperatures are cooler, and transplant stress is lower.
• Early spring (as soon as ground is workable) is a second acceptable window, especially for bare-root stock and some trees. Avoid planting in summer unless you are prepared for intensive irrigation.
• Plant evergreen windbreaks and salt-tolerant shrubs in spring or early fall to maximize establishment before winter salt exposure.

Practical takeaway: prioritize fall planting for trees and shrubs when possible.

Which trees and large shrubs to choose first (regional recommendations)

Northern and inland New Jersey (zones 6a-6b)

• Native canopy trees: Red maple (Acer rubrum), White oak (Quercus alba), Northern red oak (Quercus rubra).
• Understory/ornamental: Eastern redbud (Cercis canadensis), Serviceberry (Amelanchier spp.), River birch (Betula nigra) in wetter spots.
• Shrubs: Viburnum species, New Jersey tea (Ceanothus americanus), and native hollies.

Central and suburban New Jersey (zones 6b-7a)

• Canopy and street trees: Sugar maple (Acer saccharum), Hackberry (Celtis occidentalis), Tulip tree (Liriodendron tulipifera).
• Foundation and privacy shrubs: Boxwood (for sheltered sites), Leyland cypress (for rapid screening, with caution about size), and native Ilex (American holly) for seasonal interest.

Coastal and southern New Jersey (zones 7a-7b, sandy soils)

• Salt-tolerant trees and shrubs: Eastern red cedar (Juniperus virginiana), Bayberry (Morella pensylvanica), Beach plum (Prunus maritima) for dunes and exposed areas.
• Grasses for stabilization: Little bluestem (Schizachyrium scoparium) and switchgrass (Panicum virgatum).

When selecting species, favor native or regionally adapted varieties for resilience, pollinator support, and lower maintenance.

Soil testing and amendment: do this before planting

A simple soil test from your county extension or a commercial lab is worth the cost. It informs pH, nutrient levels, and organic matter needs.

• Adjust pH only if required. Many New Jersey natives tolerate slightly acidic soils; azaleas and rhododendrons prefer lower pH.
• Incorporate 2-4 inches of compost into the top 8-12 inches of planting beds to improve structure and moisture retention.
• For heavy clay soils, add coarse sand and compost and consider raised beds or planting on mounds for trees if drainage is poor.

Practical takeaway: never assume the soil is fine. Test and amend before you place expensive trees.

Mulch, planting technique, and watering for long-term success

• Mulch newly planted trees and shrubs with 2 to 3 inches of organic mulch, keeping mulch pulled 2-3 inches away from trunks to avoid rot.
• Dig planting holes twice as wide as the root ball but no deeper than the root flare; the root flare should sit at or slightly above final grade.
• Backfill with native soil amended with compost; avoid large amounts of fertilizer at planting time.
• Water deeply at planting and continue with a soak-and-rest pattern: when soil is dry in the top few inches, give a deep watering rather than frequent shallow waterings.
• For the first year: water newly planted trees 1-2 times per week in dry periods. Second year: taper off to encourage deeper roots.

These simple habits reduce transplant shock and encourage robust root systems.

Lawns and groundcovers: when to do them

If you plan a lawn, schedule seeding for late summer to early fall (late August to mid-September) in most of New Jersey. This timing avoids summer heat stress and takes advantage of warm soil and fewer weed pressures.

• Choose cool-season grasses: tall fescue mixes for heat and drought tolerance, Kentucky bluegrass blends for lush sod in well-watered sites, or perennial ryegrass for quick establishment.
• If you prefer low-maintenance alternatives, use native groundcovers such as Pennsylvania sedge (Carex pensylvanica) or a mix of low-growing natives and clovers.

Practical takeaway: do not seed a lawn before planting major trees unless you can protect root zones; plant trees first, then establish lawn around them.

Perennials, ornamental grasses, bulbs, and annuals: finishing touches

Once large plants and lawn are installed and settled, add perennials, grasses, bulbs, and annuals. This sequencing prevents smaller plants from being trampled or displaced during heavy equipment work and tree root establishment.

• Perennials and ornamental grasses establish best in spring or early fall.
• Spring-flowering bulbs (tulips, daffodils) are typically planted in fall after trees and shrubs are in place.
• Annuals and seasonal containers are the final layer for color and can be changed each season as design evolves.

Practical takeaway: treat bulbs and perennials as the final aesthetic layer; they are easiest to place once the hard structure is set.

Deer, salt, and pest considerations in plant choice and placement

• Deer-resistant doesn’t mean deer-proof. Use a combination of plant selection (bayberry, hollies, native grasses), barriers, and repellents where deer browse is heavy.
• For coastal and salt-prone sites, prioritize salt-tolerant species and plant behind buffers (fences or hedges) to reduce direct spray damage.
• Inspect plant health regularly during the first two years and treat problems early: scale, borers, and fungal issues can be managed more effectively when caught early.

Practical takeaway: match plants to site hazards rather than trying to retrofit protections later.

Example planting scenarios and palettes

Small urban yard (north-central New Jersey)

• First: 1 small ornamental tree such as Eastern redbud or serviceberry placed for spring color and limited shade.
• Second: 2-3 evergreen shrubs for year-round structure (boxwood or dwarf holly) along foundation.
• Third: lawn alternatives (sedges or a small turf of tall fescue) and a perennial border of native asters and coneflowers.

Coastal cottage garden (southern New Jersey)

• First: wind-tolerant screening trees and shrubs like Eastern red cedar and bayberry.
• Second: structural dune grasses and ornamental grasses for texture and erosion control.
• Third: hardy perennials and seaside bulbs, finished with annuals in containers.

Suburban family yard with privacy needs

• First: evergreen privacy hedge (native holly or Thuja cultivars placed at correct spacing and setbacks).
• Second: shade trees placed to protect the house and create play areas.
• Third: lawn seeded in late summer and perennial beds under existing trees planted in the following spring.

These templates illustrate sequencing more than exact species lists; adjust species to your exact zone and soil.

First two-year maintenance calendar (practical checklist)

• Year 0 (planting year, fall or spring): soil test, install trees/shrubs, mulch, water deeply and regularly, avoid heavy pruning except to remove dead wood.
• Year 1 (establishment): monitor watering frequency; reduce shallow watering gradually. Apply a topdressing of compost in spring. Monitor for pests and deer browse. Do formative pruning in late winter if needed.
• Year 2: taper establishment irrigation further; plan any additional plantings of perennials and bulbs in fall. Begin long-term maintenance schedule of fertilization for lawns in fall and early spring.

Maintaining a simple calendar reduces mistakes and extends plant life.

Final practical takeaways

• Always start with a site assessment and soil test; invest effort in the ground before buying plants.
• Plant trees and large shrubs first, ideally in fall, to establish structure and shade patterns for the entire yard.
• Amend soil with compost, mulch correctly, and water deeply rather than frequently.
• Seed lawns in late summer to early fall; install perennials, bulbs, and annuals after structural elements are in place.
• Choose regionally adapted and native plants whenever possible to reduce maintenance, support wildlife, and avoid replacement costs.

Thoughtful sequence and attention to site specifics will make your New Jersey landscape resilient, attractive, and easier to maintain over the long term.
