Choosing a Supplier of Trellis Netting for Windy Sites

A net that works neatly for peas may sag under the weight of a tomato crop. A climbing pea needs a different opening and support height from a heavy tomato system or a commercial cucumber crop. The mesh must give tendrils or training clips something useful to hold without creating excessive interference with harvest. Before ordering, decide whether the material will be installed vertically, horizontally or as part of a more complex structure. A net intended for one orientation may behave differently when turned or tensioned another way.

Wind loads are easy to underestimate. Dense foliage can act like a sail, transmitting force through the net to the posts and anchors. A light-looking plastic mesh may be strong enough in a short sample but the supporting frame may still fail when wind acts on the whole planted row. Review the length of unsupported spans, the condition of end posts and how tension is carried into the ground. Site exposure matters; a sheltered growing tunnel and an open coastal plot are not the same installation. When contacting a supplier of trellis netting, share the exposed span and support-post arrangement, not only the mesh opening.

Fixing methods should not cut into the net. Sharp wire ends, over-tight ties and poorly positioned staples create local stress points. Use compatible fixings and check whether the material needs some freedom to move with temperature changes. If the net is reused between growing seasons, inspect it for UV ageing, brittle strands and previous damage before putting it back under load. A strand that snaps easily by hand is not a promising sign, even if the rest of the roll still looks clean.

At the end of the season, inspect the highest-stress points. Look near tie locations, end anchors and parts of the row exposed to wind. Photograph where strands broke so the next layout can be adjusted. If the material was intended for reuse, assess whether it remains strong enough before storing it. A simple seasonal record turns field observations into a useful basis for the next order instead of relying on memories of the worst storm.

Trellis netting behaves differently once wind, water and fruit weight enter the picture. A greenhouse team can install a short trial run at its normal support spacing, then observe sagging and attachment wear during irrigation and harvest. Mesh opening should suit the crop and the way workers reach through the net; larger gaps are not automatically easier to use. Keep notes on UV exposure, breakage at ties and whether the net can be removed without damaging plants. Those field observations are more relevant than a generic claim that the material is strong.

Harvest and removal deserve advance planning. A mesh that supports the crop beautifully can become frustrating if plants are difficult to separate at the end of the season. Consider whether the system will be disposable, reused or removed with the crop residues. Waste handling differs by material and local practice; avoid assuming that a product described as recyclable will actually be collected by a local recycling stream. Labour costs from installation and removal belong in the comparison.

Large growing operations should test the handling process before buying a full season's stock. How quickly can workers hang a roll without tangling it? Are the cut ends manageable? Does the chosen mesh work with existing posts and clips? Installation time can become a substantial cost when the same small task is repeated across many rows. A netting product that is slightly cheaper per metre may prove more expensive if its packaging or stiffness makes installation difficult.

The cost of crop support also includes crop access. A narrow mesh may hold vines securely but make selective harvest or pruning more awkward. In protected cultivation, the net should work with carts, irrigation lines and existing crop-management routines. Walk the planned installation with the people responsible for harvest before ordering. Small access constraints multiplied across hundreds of plants can turn a nominally inexpensive support system into a significant labour burden.
