How to choose a garden trellis
Updated: October 2026
A garden trellis can mean four different products: a lattice fixed to a fence, a small stake pushed into a pot, elastic netting for a grow tent, or a folding screen on feet. Choosing by star rating alone can leave you with the wrong object. Start with the surface, the width and the plant, then compare brands. The Products Compared editorial team used amazon.co.uk extracts in the [garden trellis comparison](/hub/plant-accessories/trellis), not a garden trial. A qualifying purchase can earn a commission at no extra cost to you.

Four products share the word trellis
An expanding wooden lattice is the familiar fence or wall option. Most examples here open to roughly 180 cm by 30 cm, with thin crossed laths joined by rivets or pins. Opening the diamonds changes both dimensions, and the lattice needs support behind it.
A pot trellis is much shorter and has prongs for compost. The plastic set measures 18.2 by 35.8 cm per piece and can be stacked, which suits a pothos or ivy better than a 1.8 m lath. See trellis for potted plants if the roots and the support share one container.
Elastic netting stretches across a grow tent and attaches with hooks. It is not a fence panel. A freestanding screen has feet where you cannot drill, but it can blow over, and it is not a barrier for children or pets. The Royal Horticultural Society keeps freestanding screens to sheltered sites.
Width matters more than the 180 cm length
The repeated 180 x 30 cm size sounds substantial until you mark 30 cm on a fence. It gives one light climber a route upwards, or fills a slim gap beside a gate. It will not cover a standard fence bay. An expanding lattice becomes narrower as you stretch it, so check the size in the position you will use.
Wider panels exist outside this comparison. UK Garden Supplies lists 180 cm-high versions from 30 to 120 cm wide, from about £8.99 including VAT. Waitrose Garden lists a heavy-duty expanding trellis at 1.8 by 1.2 m, at £16.99. Those are shop pages, not listings in this set. If the lattice sits above a boundary, read trellis on a fence before you buy the extra height.
Match the support to the plant, not the star rating
Thin expanding laths suit light climbers you can tie in. Sweet peas, young clematis and jasmine appear in reviews of this set. The support still needs a gap so stems and air can pass. RHS guidance includes both wires and trellis on battens.
Wisteria develops weight and leverage, and climbing roses are not self-clinging, so both need a support planned for mature growth. Toyosport and LATERN each state a 10 kg capacity. Those are seller claims, not an independent test. Do not read heavy duty as a guarantee.
Several listings say the wood is treated or carbonised without a BS 8417 use class. That word does not tell you to bury the lath. Keep the bottom clear of wet ground. The AC Infinity product is a 60 by 120 cm grow-tent net. The best garden trellis shortlist keeps product type ahead of the headline rating.
What this comparison can and cannot tell you
The comparison contains six expanding wooden lattices, one stackable plastic pot set, one elastic tent net and two freestanding screens. Use it for pack count, stated open size, joint type, price and the failures reviewers repeat. Wooden packs run from about £7 to £20. The footed screens cost about £59.99.
Gardman has a large review file and a stated 1.8 by 0.3 m size, and buyers still report splitting without a pilot hole. Some Kanta reviews report pins or rivets pulling out as the lattice opens. There is no garden trial here, and no rigid panel or metal trellis in the set.
Common questions
Is expanding trellis the same as a rigid fence panel?
No. Expanding trellis consists of crossed laths joined at pivots, so its height and width change as the diamonds open. A rigid panel has a fixed frame and dimensions. The expanding type is lighter and easier to transport, but it generally needs support and careful fixing.
Is a 30 cm-wide trellis enough for clematis?
It can provide a narrow climbing route for a compact or young clematis, provided the support is spaced from the fence and the stems are tied in. It will not cover a whole fence bay. Check the mature spread of the cultivar before treating one narrow strip as the final support.
Should I buy a freestanding trellis instead?
Choose feet when you cannot drill and the site is sheltered. Do not assume a light screen will withstand wind or restrain a pet. Reviews mention weighting footed screens, and B&Q warns that its expanding screen is not a child or pet barrier.
Does treated wood guarantee outdoor durability?
No. Treated without a use class, process or service-life statement is limited information. Keep the wood clear of soil, inspect cut edges and joints, and follow any care instructions. A vague listing claim should not replace construction details when longevity matters.
When are wires better than lattice?
Wires are useful when you want adjustable horizontal spacing, less visual bulk or a support designed around a particular climber. They still need sound anchor points and suitable ties. For heavy woody plants, plan the complete fixing system rather than assuming either wire or thin lattice is automatically strong enough.
Are screws normally included with expanding trellis?
Not in the wooden lattice listings compared here. Gardman, Kanta, LATERN and Toyosport do not list mounting hardware. Budget for battens, appropriate exterior fixings and plant ties, and choose those fixings for the fence construction.
