Espalier is the horticultural technique of forcing woody plants to grow flat along the same plane as a wall or fence. This is achieved by systematically pruning branches to restrict plant growth and guiding the branches in a selected direction until the plant assumes the desired shape. The plant is anchored to its companion wall (fence), or else to a trellis running parallel to the wall, via an elaborate support system that serves as a framework.

Espalier is an ancient art form that goes back at least to the Romans. It is similar to the art of topiary in that, in both cases, you are giving a plant an artificial shape, guiding its growth by means of a framework and intensive pruning. But espalier differs from topiary in that the resulting shape is two-dimensional (with a height and a width, but with no depth to speak of), not three-dimensional.

The word, "espalier, " is French, and it can be a noun or a verb. As a noun, it can refer not only to the technique just described but also to the supporting framework or to the plant so trained. As a verb, it refers to practicing said technique.

Espalier has both aesthetic and practical purposes. You can use this art form to dress up a blank masonry wall, especially if you select a plant with nice flowers and/or attractive fruits; indeed, fruit trees are a popular choice for espalier. Growing an espalier along a chain-link fence can give you more privacy. In a yard where space is at a premium, an espalier serves as a great space-saver. Running along a solid, south-facing wall, an espaliered plant can enjoy a microclimate where temperatures are warm enough to extend the growing season. Finally, because the dimension of depth has been almost totally eliminated (an espalier has height and width, but no depth to speak of), each leaf of a fruit tree can receive full sunshine, meaning better fruit production per square inch.

When to Espalier

Begin an espalier when the plant is still young. This is when the plant will be most agreeable to taking on the shape you wish to give it, through pruning. The best time to buy the tree and plant it is spring or fall. Buy a plant that is small, so that, as it grows and branches out, you will have the opportunity to selectively prune off branches and thereby control the shape that the plant will take.

Espalier is an ongoing procedure, but, once the espaliered plant has matured (5 to 10 years) and assumed its basic shape, the remaining work is easier and simply a matter of maintenance.

This maintenance consists of pruning three times a year to remove unwanted branches:

  • Winter
  • Early spring
  • Early summer

Do not prune in late summer or in fall. This would only encourage tender growth that will not be sufficiently hardened off to survive winter, thereby inviting damage.

Styles, Shapes, and Supports

There are different styles and shapes to choose from when creating an espalier. Some gardeners prefer a highly formal style (where the plant is trained to assume a precise pattern). Others like an informal style.

Within these styles, there are also variations; in the formal style, you must decide how many levels or "tiers" (main branches spreading left and right from the trunk) your espalier will have. This decision can be influenced by how tall a wall you have behind the espalier: For a very tall wall, you may want to have more tiers, since this will give you better coverage.

You must also decide on a way to support an espalier. One option is to build out a framework directly from the wall. There are specialty supplies available for working with masonry (for example, concrete nails). For a wooden wall, screw eyes can be effective. You would then string 9-gauge wire between the nails or screw eyes to establish the lines for your tiers.

But it is easier to erect a separate trellis. This way, you will not have to worry about damaging your wall. Besides, a trellis has openings in it, through which you can easily thread ties that will bind the branches to the supporting framework. 

What You'll Need


  • Pruners
  • Shovel
  • Tape measure
  • Carpenter's level
  • String level
  • Circular saw, jigsaw
  • Drill, screws
  • Hammer, nails
  • Garden hose


  • Compost
  • Mulch
  • Suitable plant
  • Two stakes
  • Twist-ties
  • Scrap lumber
  • Two 4 x 4 pressure-treated posts, 8 feet long
  • 4 x 8 wood lattice panel
  • 1 inch x 8 inch x 8 foot board
  • Quick-setting concrete

Twist-ties can serve both to anchor branches to the framework and to mark projected growth (by tying them to the framework to plot out where you want the plant's branches to grow eventually). Not only are they versatile, but they are also free (recycle the ones you have used to tie grocery bags). Stretchy plant ties do exist that are safer to use because they will not girdle branches, but they cost money. If you do not wrap twist-ties tightly around branches, you can avoid girdling.

Best Plants for Espalier

While many types of woody plants can be espaliered, highly formal espalier work is more suitable for certain kinds than it is for others. Over the centuries, practitioners of the art have learned by trial and error which plants adapt better to espalier and have passed this information on to future generations. A feature that many plants best-suited to highly formal espalier share is flexible lateral branches. As with any plant project, make sure your selection is suited to your zone.

Traditionally, fruit trees were more commonly espaliered than other plants, precisely because many of them do have flexible lateral branches. If you are inspired by this ancient tradition and wish to stay authentic by practicing espalier on fruit trees, take note that small fruit trees are the best choice. But you are in no way limited to fruit trees or even to trees, generally; you can espalier shrubs and woody vines, too. Here are some great choices for espalier:

Apple Trees

A plant that is commonly espaliered is the apple tree (Malus spp.). Semi-dwarf types (12 to 16 feet tall) are popular in espalier. Fully dwarf kinds (5 to 8 feet tall) are even more suitable. Not only do you save space by espaliering an apple tree, but you also make it easier to harvest its fruit.

Bloodgood Japanese Maple Trees

Bloodgood Japanese maple trees (Acer palmatum atropurpureum) offer beautiful foliage but may become too large for a very small yard. If you want to enjoy one without worrying about space considerations, espalier it. Such a great foliage plant is an excellent choice for an espalier designed to lend interest to a blank wall.


Gardenia jasminoides is hardy only in zones 8 to 11, so Northerners will not be able to enjoy its showy flowers in an espalier. If you are lucky enough to garden where Gardenia can survive outside year-round, set up your espalier where you will be spending the most time outdoors: You want to be close enough to it to be able to inhale its wonderful fragrance.

Winter Jasmine

Winter jasmine (Jasminum nudiflorum) is a borderline-hardy plant in zone 5 and above. If you are a Northerner, grow your espalier with this vine in a sheltered area on the south side of a building where it will stay warmer than elsewhere on the landscape. Winter jasmine will reward you with yellow flowers in early spring.


In our example, we will create a highly formal espalier using a dwarf apple tree, and we will give it three tiers. For a support, we will attach the espalier to an 8-foot-long lattice trellis.

  1. Choose a Location

    Because we are growing an apple tree, we need a location with full sun and well-drained soil.

  2. Erect a Lattice Trellis

    If the trellis is to parallel a wall, locate the trellis 18 inches out from the wall. Sink your 4x4 posts 3 feet down into the ground, pouring concrete into the holes to secure them there. For further stability, attach the 1x8 board across the faces, at the top, of the 4x4 posts. Attach the lattice to this supporting structure.

  3. Plan It Out

    Using twist-ties, mark the future course of your espalier out on the lattice. We want our apple espalier to be 4 feet high and 7 feet across. So, vertically, run twist-ties 4 feet up from the ground; this is where the trunk will grow. Measure 16 inches up from the ground; this will be the height of our first tier. Run twist-ties, horizontally, 3 1/2 feet out from the vertical column at this 16-inch height, on both the left and the right. Repeat for the second and third tiers. Each tier is separated from the next one by 16 inches.

  4. Install the Plant

    Dig a planting hole in front of the vertical column that you have just marked out and place the tree in it. Other than this alignment, installing a plant for espalier is no different from installing any other plant. Add compost as you backfill; add mulch at the end.

  5. Prune the Trunk

    "Topping" is usually a dirty word, but not in this project. Prune off the top of the trunk 1 to 2 inches above the first tier, just above a bud. There should be three buds or more below this bud. The idea is to generate side-growth that will become the first tier.

  6. Create the First Tier

    Once this side-growth has been generated, keep the best branch growing horizontally to the left and the best branch growing horizontally to the right, and prune off the rest. In fall, carefully bend the branches into position so as to form your first tier. Gently tie them to the lattice with twist-ties, avoiding girdling.

    Do not make heading cuts on your lateral branches until they've grown out to the final length you want them to achieve. Once they've achieved this length, make heading cuts to stop further growth.

    While you're waiting for this lateral growth, don’t let the trunk reach more than 6 inches above the first tier; if it does, prune it to keep it "in-bounds."

  7. Create the Second Tier

    After your first-tier branches have made it 3/4 of the way across to their projected terminal point, let the trunk grow to the second tier, and repeat the process you used to make the first tier.

  8. Create the Third Tier

    Do the same to create the third tier.
