Most homeowners don’t begin this conversation by asking me about root zones, grading, or construction access. They usually point toward a large maple, oak, or pine and say something like:“We love that tree. Are we going to lose it if we redo the property?”

That’s a valid question. On a mature New England property, trees often hold much of what people value about the place. They shade the patio in July. They frame the view from the kitchen. They soften the house from the road. They may have been there when the homeowners moved in, when their children were young, or long before the house belonged to them.Sometimes the tree is the reason the property feels established rather than newly assembled.

So when I walk a property at the beginning of a landscape redesign, I’m not looking at mature trees as obstacles scattered across a plan. I’m trying to assess which of them give the property its identity, which are healthy enough to build around, and what the new landscape would lose if they disappeared.The best landscape renovations don’t begin by asking what should be removed. They begin by identifying what’s already worth preserving.

An Expert’s Summary

Yes, mature trees can often remain during a landscape redesign, and in many cases they should. A healthy, well-placed tree can give a renovated property shade, scale, privacy, seasonal character, and a sense of permanence that new planting can’t provide for decades.

But keeping a tree means more than drawing a circle around its trunk and telling the construction crew to be careful.

We need to understand the tree’s condition, species, structure, root environment, surrounding grade, and relationship to the proposed work, including how landscape drainage may affect long-term root health. We also need to look at how equipment, excavation, drainage improvements, utility trenches, walls, patios, pools, and new planting will affect the soil around it.

Some trees can tolerate a thoughtful redesign nearby. Others can’t withstand the amount of disturbance a project would require. Occasionally, a tree that looks important from across the lawn turns out to be declining, structurally compromised, or poorly located. In other cases, the tree everyone assumed would need to go becomes the organizing feature of the entire design.

Our job is to tell the difference early, before the plan gets too far ahead of the property.

Evaluate important trees before finalizing the landscape plan.
Preserve the trees that are healthy, structurally sound, and meaningful to the property.
Design patios, walls, paths, drainage, and gathering spaces around real root conditions, not just the visible trunk.
Establish tree-protection limits before construction begins.
Be honest when preserving a tree would create an unsafe condition or compromise the entire renovation.

The goal isn’t to save every mature tree at any cost. It’s to preserve the right trees and make decisions that will still look sensible years after the construction crews have left.

The Question

We’re considering a major redesign of our backyard, including a new patio, better drainage, new plantings, and maybe a small pool. Several mature trees surround that space, and they’re a big part of why we love the property.

We’ve been told that some of them may need to come down to make the project work. Is it realistic to keep mature trees during a renovation, or do they usually become too difficult to build around?

The Not-so-short Answer

Yes, it’s often realistic to keep mature trees during a landscape renovation. In fact, when the trees are healthy and well placed, keeping them usually leads to a better design.

A mature canopy gives us something we can’t manufacture quickly. It creates proportion around the house, filters views, casts moving shade, and makes new stonework and planting feel as though they belong to an established property. You can install a beautiful patio in one season. You can’t install a 70-year-old oak.

But of course, that doesn’t mean every tree should stay.

When I first walk a property, I’m looking at more than whether a tree is large or attractive. I’m watching how it sits in the landscape. Is it leaning toward the house? Are there large dead limbs over the proposed gathering area? Does the trunk flare naturally at the soil line, or has the base been buried by years of added mulch and grade changes? Is the canopy full and balanced? Are there visible cavities, included bark, fungal growth, or signs of previous construction damage?

I’m also looking at what the tree is doing for the property. There’s a difference between a mature tree and an important tree.

A tree may be large but contribute very little. Another may not be the biggest specimen on the site, yet it perfectly frames the back of the house, screens a neighboring second-story window, or shades the one part of the terrace where everyone naturally wants to sit.

Those are the moments when experience matters. A plan can tell us the tree’s diameter and location. It can’t fully explain why the property would feel exposed without it.

I remember walking a property where the homeowners assumed a broad-limbed maple beside the existing patio would have to be removed. The patio was uneven, the circulation was awkward, and surface roots had lifted several stones. At first glance, taking the tree down might have seemed like the cleanest solution.

But once we stood beneath it, the decision became more complicated.

The maple shaded the back of the house through the hottest part of the afternoon. Its canopy created a ceiling over the garden. From inside, it softened the view toward a neighboring home that would otherwise have felt surprisingly close. Removing it would have solved one construction problem while creating three design problems.

We kept the tree.

Instead of forcing a conventional patio layout beneath it, we pulled the primary terrace farther away, adjusted the path to improve landscape circulation, and turned the area under the canopy into a quieter garden space with a looser surface and shade-tolerant planting. The finished landscape felt larger because it had more than one kind of outdoor room, and the tree remained the element that tied everything together.

That’s often the better approach. We don’t insist that an old tree accommodate every new idea. We let the tree tell us where certain things shouldn’t go.

There are also times when keeping a tree simply isn’t the responsible recommendation.

If an arborist identifies serious structural decay, if the root system has already been compromised, or if the proposed construction would remove too much of the tree’s supporting root area, we need to say that clearly. Preserving a tree on paper doesn’t help anyone if it declines several years later beside a new pool, patio, or addition.

I’m especially cautious when someone says, “We’ll leave the trunk alone.”

The trunk usually isn’t where the construction conflict occurs. The damage happens farther out, where excavation cuts roots, machinery compresses soil, grades change, or drainage patterns shift. A tree can remain standing throughout construction and still lose the conditions it needs to survive.

That’s why tree preservation needs to influence the design before construction documents are finished. It can’t be added as a note after every major decision has already been made.

If the trees matter to you, tell your landscape designer at the beginning of your backyard transformation. Walk the property together. Identify the trees you’d be genuinely upset to lose, even if they aren’t the most impressive specimens. Sometimes the tree with the greatest personal value isn’t the one a designer would notice first.

Once we understand what matters to you, we can evaluate what’s practical, bring in a certified arborist where needed, and shape the renovation around the strongest parts of the existing landscape.

That’s a much better starting point than clearing the property and trying to put its character back afterward.

My Expert Advice

One of the biggest misconceptions about a landscape renovation is that the design begins with a blank sheet of paper. It almost never does.

When I arrive at an older property in Concord, Dover, Weston, Lincoln, or Wellesley, I’m usually walking through decades of decisions. Some have been excellent. Others haven’t aged particularly well. There may be gardens that have slowly outgrown themselves, walls that have settled, drainage that no longer works, or patios that simply don’t fit the way the homeowners use the property today.

But woven through all of that is usually something that deserves our respect. Almost always, it’s the mature trees.

Those trees have quietly shaped how the property feels every single day. They influence where snow melts first in the spring. They determine which rooms stay cooler in July. They soften afternoon light. They create privacy without feeling like a fence. They make the landscape feel established instead of recently installed.

That’s why I rarely begin by asking what we’re going to remove. I begin by asking, what would this property miss if it disappeared?

Some trees become the reason the design works.

I remember visiting a property where the homeowners apologized before we even reached the backyard.

“We know the oak is probably in the way.” It wasn’t.

The tree stood just beyond the house, with broad horizontal limbs reaching over the lawn. Underneath, the grass had thinned, and the existing planting had become sparse. From a maintenance perspective, it looked tired. From a design perspective, it was extraordinary.

The canopy established the scale for the entire backyard. It made the house feel settled into the site instead of sitting on top of it. It framed long views into the garden while screening neighboring roofs without making the yard feel enclosed.

If we had removed it, we wouldn’t have been creating a better landscape. We would have been trying to replace something that couldn’t realistically be replaced in our lifetime.

Instead, the tree became the anchor around which everything else was organized. The terrace shifted slightly. Garden beds widened. Circulation changed. Seating areas moved into better light.

The design improved because we stopped asking the tree to accommodate the project and started asking the project to respect the tree. That change in perspective often transforms an entire renovation.

Healthy trees don’t always look perfect.

Another thing homeowners are often surprised to hear is that appearance alone doesn’t tell us very much. I’ve seen magnificent-looking trees with serious structural problems hidden high in the canopy.

I’ve also seen trees that worried homeowners because of a few dead branches or an irregular shape but turned out to be vigorous, stable specimens with many healthy years ahead.

That’s why I avoid making quick judgments. Instead, I’m looking for patterns.

Has the canopy gradually become thinner?
Is one side declining while the other remains healthy?
Are mushrooms appearing near the base?
Has construction occurred nearby in recent years?
Has the grade changed?
Has someone repeatedly piled mulch against the trunk?
Do large roots show signs of previous excavation?

Sometimes the answers suggest the tree simply needs better care. Sometimes they tell us the tree has been under stress for years, long before anyone started thinking about a landscape renovation. Those are two very different situations, and they deserve two very different recommendations.

The roots matter more than most people realize.

If there’s one thing I wish every homeowner understood before starting a renovation, it’s this: The most important part of a mature tree is usually the part you can’t see. People naturally focus on the trunk because that’s what’s visible. Trees don’t.

The fine roots responsible for absorbing water and nutrients often extend well beyond the edge of the canopy. They’re surprisingly close to the surface, where heavy equipment, repeated foot traffic, trenching, excavation, stockpiled materials, and changes in drainage can all affect them.

That’s why experienced contractors install tree-protection fencing long before excavation begins. It’s also why we spend so much time coordinating construction access.

Sometimes protecting a tree isn’t about changing the finished design at all. It’s about changing how the project gets built. A skid steer making repeated trips across the same area may cause more long-term damage than the finished patio itself. Moving a staging area twenty feet can occasionally save a tree that would otherwise struggle for years after construction.

Those decisions rarely appear on the final photographs, but they often determine whether the landscape looks just as healthy five or ten years later.

Not every mature tree belongs in the future landscape.

This is usually the hardest part of the conversation. People naturally become attached to mature trees, and for good reason. But age alone doesn’t make a tree worth preserving.

I’ve walked properties where nearly every design decision was constrained by a declining tree that homeowners felt obligated to save because it had always been there. Sometimes preserving that tree meant sacrificing better drainage, safer circulation, usable outdoor living space, healthier replacement planting, or long-term safety.

Those aren’t easy conversations, but they’re important ones. If we believe a tree is approaching the end of its useful life, I’d much rather discuss that honestly before construction begins than promise preservation only to watch it decline two years after the project is complete.

Removing the wrong tree is unfortunate. Building an entire renovation around a tree that cannot realistically survive is often much more disappointing.

The properties that age the best share one thing in common.

After designing landscapes throughout Greater Boston for many years, I’ve noticed something consistent. The landscapes people admire most twenty years later are rarely the ones with the largest patios or the most elaborate features. They’re the ones that still feel like they belong to the property.

The mature trees, original landforms, borrowed views, and existing character were never treated as obstacles. They became part of the design language from the very beginning.

When that happens, new stonework doesn’t compete with old trees. New gardens don’t look recently inserted. The entire landscape feels as though it has quietly evolved over time. Ironically, that’s usually the highest compliment a homeowner can receive. Guests assume the landscape has always looked that way.

In reality, that’s exactly what thoughtful landscape design tries to accomplish.

Ask a Landscape Expert

Every property has something that makes it unique. We say this every day, and all over this website.

Sometimes it’s a beautifully proportioned front entry. Sometimes it’s an old stone wall that has quietly defined the landscape for generations. And very often, it’s the trees.

They’re easy to overlook because they’ve always been there. But once they’re gone, the entire property can feel different in ways that are difficult to describe. That’s why one of the first things we do on every project is simply walk the site. Not to measure patios. Not to decide where new planting should go.

Just to understand what already makes the property feel special.Only after we’ve identified those elements do we begin thinking about everything else. Because the goal of a landscape renovation isn’t to erase the history of a property. It’s to build thoughtfully on what time has already done well.

If you’re considering a landscape renovation and wondering which mature trees should stay, we’d be happy to walk the property with you. Sometimes the most valuable advice isn’t about what to build. It’s recognizing what’s already worth protecting.
