Installing Your Trellis: The Essentials

Before you begin the installation process with your trellis, take a little bit of time to check that space that you will be placing the trellis in. Measure the space in the garden to make sure there is adequate space in the garden for the trellis you will be installing. Next make sure that the area is level to safely install. After this, take a second to dream about the garden space you are creating so you'll have a plan when installing the trellis and planting any new foliage or greenery!

Installing Freestanding Trellises

The Original H Potter trellis style, a freestanding trellis creates an instant focal point in the garden with architectural and sculptural beauty defining your garden for years to come. Design garden backdrops, flank garden beds, or create privacy screens that make a statement. Each of these pieces is a fantastic addition to the garden and also functions the best when they are properly installed. Proper installation ensures an H Potter trellis remains strong and stable despite the weather or the season. If you’re deciding whether your structure should be anchored or movable, our guide on whether a trellis can be freestanding explains stability considerations, placement options, and when seasonal repositioning makes sense.

How to Install a Freestanding Trellis in Soil

1Choose The Location

Find a space that fits the plants you will be growing, for some more sunlight or for others less. Make sure the space will fit the trellis that you are installing and the ground is somewhat level to ensure safe installation.

Mark your footprint for trellis installation

2Mark Your Footprint

Set the trellis spikes in ground and lightly press them an inch or so into the ground to mark the anchor points before final installation. For rocky or solid ground that will not allow easy installation, consider loosening the soil around the spikes a little bit to allow for easier installation.

3Constructing & Anchoring the Trellis Structure

Construct the trellis using the included H Potter instructions (if your printed guide is missing message us directly for a copy). Once assembled, position the trellis and use a rubber mallet to drive the ground stakes firmly into the soil.
If necessary due to your soil type, some of our larger trellises come with larger external stabilization spikes. Using the rubber mallet, drive these into the ground at the side of the trellis and attach using the included zip ties. This will create maximum stability for your trellising. For a deeper explanation of how to anchor a freestanding trellis for maximum stability, our step-by-step guide covers soil types, spike placement, and professional anchoring tips. When anchored properly, the trellis should not come loose in windy or adverse weather.

4Check for Level

Use a level (or if the ground is a little uneven visually check) to confirm the trellis is level and at a lower risk of tipping over. Adjust the trellis as necessary to prevent it from falling, and make sure that it is as beautiful as the rest of your garden.

Backfill and compress soil around trellis

5Backfill & Compress Soil

If you have loosened any of the soil around the trellis, make sure to press the soil firmly around the base or lightly tamp with your feet. This will prevent the trellis from leaning too far in any one direction as the soil naturally settles.

Installing Wall Trellises

A stylish trend we think is here to stay, wall-mounted trellises are a great way to add a sophisticated backdrop to any exterior vertical surface. Jazz up a home exterior, garden wall, gardening shed, or interior brick facade with these fantastic and functional decorative pieces. Whether you are planning on displaying the trellis on their own or with climbing plants and foliage, installation is important for wall trellis to make them safe for home use.

How to Install Against a Wall

1Mark Mounting Points

Before you begin installation of the trellis mounting brackets, make sure to find where the brackets will be installed. If the trellis is being attached to a house that does not have masonry or brick siding, the brackets will need to be secured in the wall studs. Locate the wall studs and mark the places the pilot holes will be drilled.

2Drill & Insert Anchors

For brick or masonry: Using a masonry drill and drill bit (you may need to purchase these at a hardware store or have a professional install the trellis) drill a pilot hole and install masonry anchors.
For wood: Find the wall studs and screw directly into them for maximum security.
For vinyl siding and stucco: drill pilot holes and attach anchors before mounting the wall brackets.

3Mount the Trellis

Attach the mounting brackets using the pilot holes and anchors. Make sure the brackets are securely fastened to the wall before placing the trellis on the brackets, with the help of another adult if the trellis too large to be moved by one person. Ensure the trellis is secured to the brackets.

4Allow Space for Airflow & Plant Growth

Make sure the trellis mounting brackets extend several inches away from the wall. This spacing allows climbing plants to weave naturally behind the trellis while promoting proper airflow and preventing excess moisture from collecting against siding or masonry.

This clearance is especially important when training vigorous climbers such as roses and clematis. For plant-specific guidance, see our detailed tips on how to trellis climbing roses and our expert advice on proper clematis care, placement, and trellis support.

Anchoring Tips for Every Trellis Style

Obelisks

Level the Obelisk trellis in the desired location. Make sure to drive the included stakes all the way into the ground to ensure the obelisk does not tip or fall over.
With their significant height, making sure the obelisk is level at the base will prevent the top from being completely out of line with the rest of the trellis.

Arbor Arches

Follow the instructions and leave the bolts only finger tight unless instructed otherwise in the assembly instructions, this will keep the structure somewhat bendable before final construction.
Always assemble Arbor pieces on the ground before raising them into the air. With the height of these trellis arch use extreme caution and never construct these on your own!

Privacy Trellis

If using multiple trellis screens, make sure to place them closely together, but not rubbing against each other to prevent the finish from becoming marred.
Perfect for blocking views or creating a backyard space that is perfectly private, these trellis should be properly installed to prevent them from tipping with the added weight of plants.

Maintenance & Rust Prevention

Built from premium materials including premium heavy-duty iron, and a 5-step finish, including a one of a kind powder coat, and clear coat lacquer finish, every H Potter trellis is built to endure. However, these trellises while weather and rust resistant are not completely indestructible and we suggest a few seasonal maintenance routines to keep your trellis looking brand new.

Seasonal Maintenance Tips

Check anchor points for mars to the finish and tighten any hardware that has come loose over time. Consider adding a layer of clear spray paint to any spot where the finish has rubbed off.
Clear exterior points of large amounts of dirt that does not stabilize the trellis itself.
Check for soil erosion around the base of the trellis that may cause the trellis to be less stable. Add and pack any extra soil that may need to be added around the base of the trellis.

Rust Prevention

Most H Potter trellises feature hand-applied powder coatings or antique finishes designed to weather gracefully. To extend longevity:

Avoid letting water pool at the base or pool long term at any location on the trellis. Additionally do not drill extra holes into the trellis as this will cause rusting and corrosion from within.
Brush off rust-colored pollen or soil stains; these are often surface-level and not corrosion.
If actual rust spots appear over time, brush the rusted material off lightly (or use fine sand paper) and apply a coat of clear spray paint to protect the trellis over time.

Troubleshooting FAQs

"My trellis wobbles, what should I do?"

If longer external spikes are included with your H Potter trellis, consider adding those to the sides and securing them to the trellis with zip ties.
Make sure the soil beneath the trellis is not too loose, as loose soil can sometimes cause the trellis to wobble.
Check that the trellis spikes are completely driven into the ground and double check that hardware has not come loose.

"I'm having trouble getting the trellis spikes into the ground?"

Make sure the ground beneath the trellis is loosened if it is very rocky or hard.
Use a rubber mallet to drive the trellis into the ground completely.

“My plants aren’t attaching to the trellis.”

Some climbing plants—such as clematis, roses, and flowering vines—require gentle training to begin attaching.
Use soft garden ties to guide new growth until the plant establishes a natural climbing pattern.
Choosing the right plant for your trellis makes a significant difference. Explore our recommendations for plants that grow best on a trellis.
For roses specifically, follow our expert tips on how to train and care for climbing roses on a trellis for healthy attachment and long-term support.

"Can I move my trellis after installation?"

Absolutely. Freestanding trellis can be repositioned seasonally. Just lift carefully and re-anchor at the new location.
