If you’re lucky enough to have a garden in a big city, you learn to accept the fact that while you’re out there, you’re in full view of everyone whose windows overlook your yard. Hanging an awning over your entire backyard or planting a tree big enough to screen everything isn’t a good option, since usually, getting the light you need to grow things is already a challenge.
So what are the best ways to make a small urban garden feel more private—or at least to create the illusion of privacy? For advice, we asked landscape designer Susan Welti, a partner in the Brooklyn-based Foras Studio. Susan has designed countless urban spaces; two of her gardens appear in our Gardenista book.
Here are some of her ideas to create privacy in a small city backyard.

Is it really possible to have privacy in an outdoor city garden?
Let’s admit that it’s almost impossible to create as much privacy as you might want. “There are so many buildings surrounding you, and they’re so much bigger than you,” Susan says. “But while you can’t block out the buildings, what you can do is to create something beautiful and compelling that will hold the eye within the confines of the site, and make you feel enclosed and secure.”
How can you use trees to create privacy?
“You can’t just throw in a big tree to block the view, because that also blocks the light,” says Susan. “In most city gardens there are trees in your sightline, but they’re often really big—such as oaks or maples or ailanthus. It’s nice to put in a tree that’s a more human scale. We use a lot of fruit trees—crab apple, dwarf apple, even pomegranate and fig. These all flower, which is always nice.”
Susan also recommends small understory trees like Chionanthus virginicus, known as “old man’s beard”; Amelanchier x grandiflora ‘Autumn Brilliance’ (serviceberry); and Magnolia virginiana—native magnolia or sweetbay. And if you’re not going for bloom, consider a Japanese maple—“They fit beautifully into a pared-back grassy landscape.”
What are the best trees for fence-line privacy?
When space is at a premium, Susan often uses trees that are pleached—trained and clipped to grow on a flat plane, like an espalier.
“Pleached trees are a powerful visual element, and you can control where they canopy out,” she says. Susan’s choice is hornbeam (Carpinus caroliniana), a native tree that takes well to pruning; she buys them already started off from Brooklyn’s Urban Arborists. “Pleached trees don’t bloom; it’s more about the shape and the beauty of the foliage.”
Can vines and climbers be used to create privacy?
“Vines are great for adding a green layer to a fence or pergola,” says Susan. “For an airy look, you want plants that have some visual porosity. We use Wisteria frutescens ‘Amethyst Falls,’ a native plant that’s less vigorous than Chinese or Japanese wisteria, and has a nice bloom.” For other flowering vines, she recommends clematis, honeysuckle, and crossvine, such as Bignonia capreolata ‘Tangerine Beauty.’ To create a wall of green, Susan suggests the vigorous, shade-tolerant Akebia ‘Shirobana’—but be aware that it’s considered invasive in some areas, so check with local authorities before planting, and be prepared to monitor its growth carefully.
