Landscaping & Irrigation
TNC Landscaping

Outdoor spaces that look intentional — and stay that way.

From first consultation to finished ground, TNC Landscaping designs and installs beautiful, functional outdoor spaces — planting, native design, and full irrigation — for residential and commercial properties across East Tennessee.

Custom Landscape Design

Master planting plans shaped to the property, the light, and the way the ground actually drains — not a template.

Native Plant Design

Species that belong in the Smokies: resilient, enduring, and a landscape that fits its mountains.

Installation & Enhancement

Planting, grading, stone accents, and seasonal color — installed by the same crew that designed it.

Irrigation Systems

Efficient irrigation designed, installed, and tuned to the planting — so the landscape has exactly what it needs, and not a drop wasted.

Drainage & Grading

Water moved off the property deliberately rather than by accident — swales, French drains, and grade set before anything is planted into it.

Lighting & Finish

Path, wash, and uplighting that make the ground work after dark, laid out with the planting rather than added to it later.

Plan it yourself

Build your budget, by the foot.

Pick your trees, beds, stone steps, lighting, decking and fencing, enter your sizes, and watch an installed price build as you go. Our real rates, labor included — so you can plan a budget before we ever meet.

How we approach it

A landscape is a drainage plan with plants on top.

Start with where the water goes

East Tennessee gets between forty and fifty inches of rain a year, and most of it arrives in a hurry. On a graded lot that water finds the lowest line and stays there. Beds installed across that line hold moisture against root collars through a wet spring, and the plants that die are blamed on the plants.

So the first thing we read on a property is not the planting opportunity — it is the fall. Where does the roof drain, where does the driveway shed, where does the neighbour's grade send water across the line, and where does all of it want to collect. Grade, swales and drains get set before a single plant is specified, because a planting plan laid over unresolved water is a plan to replace plants.

Then choose plants that want to live here

The Smokies sit across USDA zones 6b and 7a, with clay-heavy soil in the valleys and thin, fast-draining ground on the slopes. Those are different planting problems on the same property, and a plan drawn without walking both will get one of them wrong.

Native and regionally adapted species do the heavy lifting: oakleaf hydrangea, itea, viburnum, serviceberry, river birch, little bluestem, and the mountain natives that were already doing well here before anyone planted them. They ask less of the irrigation, they carry through a dry August without going to pieces, and they feed the pollinators that keep the rest of the planting productive.

  • Right plant, right place — sun, soil and mature size checked before it goes on the plan, not after it outgrows the bed
  • Layered structure — canopy, understorey, shrub and ground plane, so the planting reads as composed in every season and not just in May
  • Seasonal interest deliberately spread across the year, including winter form and bark
  • Mature spacing honoured at install, even though it looks sparse for the first two seasons — the alternative is thinning out work you paid to plant

Irrigation tuned to the planting, not to the calendar

Most irrigation problems we are called to fix are not broken equipment. They are a system watering every zone the same way — turf, beds and new trees on one schedule — which drowns half the property to keep the other half alive.

We zone to the planting: turf separately from beds, sun separately from shade, drip to shrub and perennial beds rather than spray. Drip puts water at the root and not on the foliage, which cuts evaporation loss and takes away the overnight leaf wetness that fungal disease needs. New trees get their own zone for the first two seasons, then come off it.

We build on Hunter controllers and rotors, which is what the trade in this region stocks and services — worth knowing if you ever need a part on a Saturday. Their own reference material on zoning and scheduling is genuinely good if you want to read further.

Then it has to be maintained, or none of it holds

An installed landscape is not finished, it is started. Mulch depth, pruning timing, irrigation adjustment through the season, and the dormant-season structural work are what decide whether the property looks better in year five than in year one.

Mulch is the one most often got wrong: two to three inches, pulled back off the trunk, is the whole rule. Piled against the bark it holds moisture on the collar and invites rot and voles. If you have ever seen a mulch volcano around a tree in a parking lot, that tree is on a clock.

One team draws it, grades it, plants it, and comes back to look after it — so when something is not thriving there is no argument about whose line it fell on.

Questions

Common questions

Do you design the landscaping or just install it?
Both. We plan the planting alongside the grading and hard structure so the design works as one property rather than a lawn added after the fact.
Do you install irrigation systems?
Yes. Irrigation is part of our landscaping division and is planned with the planting, so the system matches what is actually going in the ground.
Will plants survive on a steep mountain lot?
With the right selection and the right grading, yes. Slope, drainage, sun, and elevation all narrow what will establish here, which is why planting is planned with the site work rather than separately.
What planting zone is East Tennessee, and what does that rule out?
The Smoky Mountain foothills sit across USDA zones 6b and 7a, so anything rated to zone 6 will overwinter reliably here. The harder constraint is not cold, it is soil and water: clay-heavy ground in the valleys holds moisture against roots through a wet spring, while thin soil on the slopes drains fast and dries out in August. The same property often has both, which is why we walk the whole site before specifying anything.
When is the best time to plant in East Tennessee?
Autumn is the best window for trees and shrubs here. Roots keep growing in soil that stays warm well past the first frost, so an autumn planting has a full season established before it faces its first summer. Spring planting works but leaves less margin, and mid-summer planting means carrying the plant through heat stress on irrigation alone. Cool-season lawns are the same story: late summer to early autumn is the aeration and overseeding window, and it is over by mid-October.
How deep should mulch be, and does it matter?
Two to three inches, pulled back off trunks and stems. It matters more than most things on a planting plan. Mulch piled against bark holds moisture on the root collar and invites rot and voles, and anything deeper than about four inches starts shedding water instead of holding it, with fine roots coming up into the mulch layer where they dry out first. Refreshing the top of existing mulch is better practice than laying a new course over the old one every year.
How should an irrigation system be zoned?
To the planting, not to the calendar. Turf, beds, sun and shade all want different amounts of water at different intervals, and a system that runs them on one schedule drowns half a property to keep the other half alive. Beds and shrubs should be on drip rather than spray — it puts water at the root, cuts evaporation loss, and removes the overnight leaf wetness that fungal disease needs. Newly planted trees are worth their own zone for the first two seasons and should then come off it.
