Cable Ties for Agriculture and Irrigation

Most agricultural tie work falls into three groups: holding irrigation lines in place, attaching cloth and netting to structures, and supporting plants. The first two are a good fit for cable ties. Plant support can be, with care, but softer ties are often better for tender growth.

The table below uses black UV-stabilized ties for everything, since almost every agricultural job sees sunlight at some point.

Girdling happens when a tie is tight enough, or the stem grows enough, that the tie cuts into the bark or stem and restricts the vessels that move water and sugars. The damage often shows up late, as wilting or dieback above the tie, and it leaves an entry point for disease.

Cable ties are practical for sturdy, woody growth like established canes, climbing roses, and trellised brambles, and as a quick hold while you get to it with a softer tie. For tender vegetables such as tomatoes and cucumbers, and for young trees, many growers prefer vine tape, soft garden ties or clips.

1. 1Loop the tie around the trellis wire or stake first, then around the plant, so the stem is not squeezed directly against the support. A loose figure eight works well.
2. 2Leave a gap of at least a finger's width between the tie and the stem.
3. 3Place ties on stems or canes below a node or leaf so they are less likely to slide.
4. 4Never tie around a tree trunk to a stake; use a wide, flexible tree strap instead.
5. 5Mark your calendar: check and loosen or replace plant ties at least a couple of times through the growing season.
6. 6Cut out plant ties when the support is no longer needed rather than leaving them to be engulfed.

Hanging drip line on a trellis wire keeps it off the ground, away from mowers and rodents, and makes leaks easy to spot. Ties are the simplest way to hang it, though some installers use purpose-made drip line hangers or clips instead.

1. 1Lay the drip line along the row and let it sit in the sun for a while so it relaxes and the kinks come out before you tie it.
2. 2Tie at regular intervals along the wire, close enough that the line does not sag between ties. Add ties at each end post and near connectors.
3. 3Keep the loop loose. Tubing expands and contracts with temperature and pressure, and a tight tie can pinch it or distort flow.
4. 4Position emitters where they drip on the root zone, not directly under a tie where water can run along the wire.
5. 5Pressurize the system and walk the row, checking for pinched sections and emitters that moved during tying.
6. 6At the end of the season, check for ties that have cracked in the sun or been pulled by equipment.

Ties are inexpensive and fast, but some farm jobs need a stronger or purpose-made fastener. A tie's rated strength is a loop tensile figure, the load at which a new tie fails in a lab pull, not a working load, and outdoor aging reduces what it will hold.

• Greenhouse poly film on hoop houses: channel lock and wiggle wire or the manufacturer's system are the usual approach
• Trellis end-post anchors, high-tension trellis wire and anything carrying crop weight on the main wire
• Livestock fence under pressure from large animals
• Electric fence, which needs insulators rated for the charger
• Pressurized hose and fitting connections; use proper hose clamps or fittings
• Staking young trees, where a tie can girdle the trunk
• Mounting or lifting anything heavy, including panels, tanks or equipment

Black ties are UV-stabilized for outdoor use. Natural Clear White ties are made for indoor and general-purpose use and will break down much faster in sunlight, so they are the wrong choice for fields, orchards, vineyards and greenhouses.

Natural ties can make sense in a packing shed, a workshop or a fully enclosed indoor grow room away from sunlight. If you are not sure whether a spot sees sun, or plants are under lamps that may emit UV, use black.

Trellis and drip work uses ties in quantity, and running out mid-row costs more in labor than the ties do. Standardizing on two or three black lengths, such as 8, 14 and 24 inch, covers most jobs and keeps trucks simple to restock.
