Most HDPE netting does not fail in the field — it fails in the barn. A net that is stored wet, folded on concrete, or left in direct sun off-season degrades years faster than the same net stored properly. Off-season handling is where you buy back lifespan you already paid for.
HDPE netting is UV-stabilized, but stabilizer slows degradation — it does not stop it. Sun, damp and dirt all work against the yarn between seasons. A net stored dry, dark and off the ground keeps its strength; a net left muddy and damp develops weak spots that tear exactly when you put it back under load. The factors that set HDPE lifespan are mostly decided at purchase — but storage is the one you control every year.
Rinse the net with water to remove soil, sap and fertilizer residue before putting it away — mud holds moisture and grit against the yarn for months. Let it dry completely, then fold or roll. Do not use harsh solvents or high-pressure washing at close range, which can scuff the yarn. A simple rinse and full air-dry is enough.
Three rules. Dry: damp nets mildew and weaken. Dark: out of direct sun, since UV is the main degradant. Off the ground: on pallets or shelving, not bare concrete or soil, so rodents and ground moisture stay away. Rats and mice will nest in folded netting and chew holes through it — an off-ground, sealed storage spot is cheap insurance.
Roll large sheets rather than stuffing them into sacks; folding along the same creases every year stresses the same yarn lines. Label each bundle with its GSM, mesh and size before you store it, so next season you know what you are pulling out instead of guessing. Repairs are easiest now, not at harvest — patch border tears with HDPE twine while the net is clean and dry. See our bird netting rip guide for the common failure points to check.
Clean it, dry it fully, and store it dark and off the ground on pallets or shelving. Moisture and direct sun between seasons degrade the yarn faster than a whole growing season in the field.
You can, but you shorten its life. Snow load, wind flapping and months of sun all work on the net. Where practical, take it down, clean it and store it for the off-season.
Patch it with HDPE twine while the net is clean and dry, preferably right after harvest. A five-minute border repair saves a full panel next season — the border is where most failures start.
Damp, direct sun and rodents, in that order. Mildew weakens yarn, UV breaks it down, and rats chew holes. Dry, dark, off-ground storage avoids all three.
