Trellis Netting 15cm Mesh – Plant Support Net for Tomatoes, Beans, Cucumbers & Climbers | LightHouse

LightHouse Trellis Netting – 15cm Mesh Plant Support Net in 2 Sizes (1.5m x 4.5m & 1.5m x 9m)

Here's an awkward truth about plants: every bit of energy a tomato spends holding itself upright is energy it isn't spending on tomatoes. Nature's solution is to lean on something. Ours costs about the same as a bag of compost and lasts for years.

LightHouse Trellis Netting is a soft, flexible, heavy-duty polyester net with a generous 15cm (6") square mesh, made for climbing crops, top-heavy flowers and indoor growing alike. Choose 1.5m x 4.5m (5ft x 15ft) for about 6.75m² of support, or 1.5m x 9m (5ft x 30ft) for about 13.5m², double the length for very little more money. String it vertically as a climbing wall or horizontally as a crop support layer.

Why the Holes Are the Point

A trellis is mostly air, and that's deliberate. The 15cm reach-through mesh means your hand goes through the net instead of around it, so pruning, tying in and picking take seconds rather than a wrestling match. That open square also lets the net carry more weight and stay taut, which means stronger support and less crop damage. You're not fighting the net to get to the fruit.

Key Features

• 15cm (6") square reach-through mesh for easy training, pruning and harvesting.
• Heavy-duty, durable polyester that is soft on stems yet strong enough for heavy, fruit-laden crops.
• Non-tangle, so it unpacks and spreads out without turning into a bird's nest.
• Use vertically or horizontally as a climbing wall or horizontal crop support layer.
• Two sizes, both 1.5m (5ft) wide: 4.5m or 9m long.
• Cut to size with ordinary scissors, and reusable season after season.

Which Size Do I Need?

Not sure? Go long. Spare net is cheap to keep in the shed; a second trip to the shops mid-season is not. Tall crops usually end up wanting two layers anyway.

Perfect For

• Tomatoes: cordon and bush types. Weave stems through as they grow instead of tying every one to a cane.
• Cucumbers, squash & melons: train vines up instead of across the floor for cleaner, straighter fruit.
• Runner beans, French beans & peas: tendrils and twining stems grab the mesh on their own.
• Chillies & peppers: a horizontal layer stops heavy, fruit-laden branches splitting.
• Climbers & cut flowers: sweet peas, clematis, morning glory, plus tall stems like chrysanthemums, dahlias and sunflowers stay upright.
• Indoor gardens & conservatories: stretch it across a frame as a horizontal support layer to spread plants out, even up the light and hold top-heavy flowers upright.
• Greenhouses, polytunnels, fences, walls & raised beds: an instant, low-cost trellis wherever you need one.

How to Install

Vertically (climbing wall): Set a sturdy post, cane or frame at each end of the row. Fix the top edge to a taut wire, string or bar, then pull the net down and peg or tie the bottom edge so the whole sheet stays tight. A tight net carries far more weight than a loose one.

Horizontally (crop support): Stretch the net level over the bed or across a frame, tying each corner and the sides every few squares. Set it just above young plants and tuck new shoots under or through the mesh as they grow. For tall crops, add a second layer higher up.

Cutting to size: Snip with scissors to fit a smaller bed or frame. Cut just outside a knot so the edge stays secure.

Trellis Netting vs Canes & Ties

Canes support one stem at a time and need endless tying. A net supports the whole row at once, holds every branch exactly where you put it, spreads plants out for better light and airflow, and goes up in minutes. At the end of the season it folds into a pocket-sized bundle instead of a bundle of bamboo you trip over all winter.

Rose's Pro-Tip

Put the net up before your plants need it. Threading young, bendy stems through the mesh is easy; wrestling a mature, heavy plant into a net is how branches get snapped. Indoors, run the first horizontal layer about 20–30cm above the pots and add a second as the plants stretch. Pair it with a roll of Garland garden wire for a drum-tight top line.

Frequently Asked Questions

Can I use it horizontally indoors?
Yes. Lay it level across a frame, tie it taut and trim the excess. One 9m pack can do several beds or two layers.

Will it hold heavy crops like cucumbers or tomatoes?
Yes, when it's pulled tight between solid supports. For big fruit like melons or squash, a small sling takes the weight off a single stem.

Can I cut it?
Yes, with ordinary scissors. Cut just beyond a knot to keep the edge intact.

Is it reusable?
Yes. Pull out the old plant material at the end of the season, let it dry and fold it away for next year.

Can I use it outdoors?
Yes. It's used on fences, allotments and garden beds as well as in greenhouses and indoors.

What's the difference between this and pea netting?
Both have a 15cm mesh. This trellis netting is soft, flexible polyester in handy 1.5m-wide packs. Our LightHouse pea netting is a 2m x 25m roll for bigger jobs.
