Eight of the best plant supports and garden obelisks in 2023
Support climbing plants and herbaceous perennials with our pick of obelisks and plant supports.
No matter what size your outdoor space, with obelisks and plant supports, you can bring vertical elements to your garden, adding height, structure, and definition.
Obelisks are ideal for climbing plants throughout the garden, allowing them to grow upwards while being supported and without relying on walls and fences. They can add a different dimension to your landscaping and can become a real aesthetic feature. Plant supports can also help plants grow healthily and prevent herbaceous perennials from flopping over paths, lawns or their plant neighbours.
Below, we’ve curated a list of the best obelisks and other plant supports to help you make the most of all the climbing plants in your garden.

What to grow on a garden obelisk?
Obelisks are a perfect way to elevate your garden’s aesthetics, while providing plants with optimal growing conditions and the potential to climb. There are a range of plants well-suited to growing on a garden obelisk, including the following:
Climbing roses: Transform your obelisk with an array of colourful climbing roses for a fragrant feature in the garden.
Clematis: Clematis plants are great for growing on your obelisk, with their twining stems and colourful blooms draping elegantly from the structure.
Sweet peas: Scented sweet peas are vigorous climbers and need support to thrive, so a garden obelisk is the ideal solution.
Honeysuckle: Honeysuckle will weave beautifully around your obelisk, adding charm and delicious fragrance to your garden.
How to secure a garden obelisk
Once you have chosen your garden obelisk, it’s essential to secure it properly before growing your climbing plants. Below are various steps to follow to ensure it stands tall and stable:
- Find the right location: First things first, ensure you pick a secure spot in your garden to position your obelisk.
- Concrete anchoring: In your chosen spot, dig a hole at least two feet deep, fill it with concrete and place your obelisk’s base into it while wet. This will provide a sturdy structure.
- Metal anchoring: Screw metal ground anchors, such as spiral or auger-type stakes, into the ground firmly at the base of the obelisk. Fasten securely, making sure they are deep enough to ensure the plant’s stability.
- Lattice or trellis: Attach lattice or trellis to the sides of your obelisk to provide additional support to your climbing plants.
- Guy wires: For tall structures, or in extra windy conditions, consider attaching guy wires to the anchor points of your obelisk. These will prevent any unnecessary movement and disturbance.
