An olive net that dies in two seasons wasn’t badly made — it was badly kept. The same knitted HDPE net lasts 3–10 harvests depending almost entirely on what happens to it in the weeks around harvest: how it’s dragged, when it’s cleaned, and how it’s stored. The direct answer for longer life: shake off fruit and debris daily, never bale a wet net, wash before storage, and keep it folded dry and dark until next October. This is the after-harvest care guide — written while the Mediterranean harvest is running, for the growers and cooperatives pulling nets right now.
Buyers assume UV kills the net. In reality, UV takes seasons; mud and moisture take one. The three killers we see in every warranty conversation: nets dragged over stony ground collect abrasion wear at the contact points; nets baled wet come out of storage with mold-welded layers and weakened yarn; and nets stored in sun lose the UV stabilizer package months faster than nets stored dark. A harvest net’s worst enemy is never the October sun — it’s the November corner of a damp shed.
The care that matters most happens while the net is still working. Shake fruit and debris off daily — olive mass left overnight traps moisture against the knit and adds dragging weight. Lift, don’t drag, when moving the net between trees — dragging over dry stony soil is the single biggest abrasion source; two people and ten seconds is cheaper than a panel. When nets are rolled or baled between rows, never bale them wet: if rain catches you mid-harvest, spread the net over a fence line or the tree row itself for an hour before rolling. And keep the reinforced edges taut to the ground anchors — a flapping loose edge in autumn wind scuffs itself against the ground all night. Between rows in wet weather, fold the used panels onto the clean net you’re about to spread rather than onto bare mud; the minute of tidiness saves an hour of washdown in November.
Before storage, give the net a wash: low-pressure water only — a hose, not a pressure washer, which forces grit into the knit and frays the yarn surface. The point is removing the organic film (olive juice, leaf pulp, dust) that feeds mold in storage and stiffens the mesh by spring. Spread the net flat or over a line until bone dry — this is the step everyone skips, and the step that decides whether next year’s net unrolls clean or peels apart in mold-fused layers. No detergents, no bleach: plain water does the whole job.
October is repair season, not purchase season. Walk each panel as it comes off: small holes and edge tears get a cable tie or a folded patch now, while you remember where they are — the grower who repairs in autumn unrolls a ready net next harvest; the one who postpones discovers the holes with the fruit already dropping. A panel with a dozen repaired holes is still a working panel; a panel with a torn edge seam is not — edge damage spreads under the shaker’s vibration, so edge repairs get priority.
Fold panels flat along their length rather than tight-rolling them — flat folds put no crease memory into the knit and stack cleaner on pallets. Store them off the ground (pallets or a rack), under cover (UV in storage counts double: no fruit shade above, no work to justify it), and dry — a ventilated shed beats a sealed container, because residual moisture needs somewhere to go. Rodents nest in stored netting more often than buyers expect; a pallet off the floor and a closed door solve that too. One habit that saves the first day of next harvest: label each stack by panel size before it goes into the shed — the crew that unrolls in October shouldn’t be measuring nets to remember which stack goes under which tree row.
Same net, same grove, different habits: a dragged-wet-baled net lasts 2–3 seasons; a lifted-washed-dark-stored net lasts 8–10. Our olive nets are 85–100 gsm virgin HDPE with reinforced edges and knitted eyelets, built for the multi-season duty — but the material only delivers its rated seasons when the handling does its half. For cooperatives and distributors, this is also the after-sales conversation that retains customers: the buyer whose nets serve eight seasons buys the replacement set from you, and tells the neighboring grove why.
If this harvest showed you panels that won’t survive another year, the time to replace them is the off-season, not September. Production runs 25–35 days after deposit, and harvest-deadline orders pile up in late summer — the growers who receive their nets in time for the October start are the ones who ordered by midsummer. A 40’HQ carries 14–15 tons of olive netting — roughly 140,000–175,000 m², enough for a cooperative’s whole season. MOQ is 2 tons with mixed panel sizes (3×6 m to 12×12 m) in one shipment; samples free, you cover the courier. Send your panel count and sizes via the contact page or WhatsApp and we’ll quote within 24 hours. If you’re still choosing specs, the olive net GSM guide and the panel sizes guide cover those decisions.
3–10 seasons depending on grade and handling. The biggest factor is not the sun — it’s mud and moisture: nets lifted (not dragged), washed before storage and stored dry and dark reach the top of the range; baled wet or stored damp, they’re done in 2–3.
Yes — low-pressure hose water only, no detergents. The goal is removing the organic film (olive juice, leaf pulp, dust) that feeds mold in storage. Spread the net flat until fully dry before folding; a pressure washer frays the yarn.
Folded flat (not tight-rolled), off the ground on pallets, under cover and dry — a ventilated shed beats a sealed container because residual moisture needs to escape. Sun exposure in storage burns UV stabilizer without doing any work.
Yes — repair in autumn, not before harvest. Cable ties or folded patches on small holes while you remember where they are; edge-seam tears get priority because they spread under shaker vibration next season.
In the off-season, by midsummer for the October–December Mediterranean harvest. Production is 25–35 days after deposit plus ocean freight; orders placed in September compete with everyone else’s harvest deadline.
Lift, don’t drag. Wash before storage, never bale wet. Fold dry, store dark. Repair in October, not September. Send your panel sizes and count and we’ll spec the replacement set of olive harvest nets for next season.
