The short answer: Choose garden netting based on the pest you are excluding, measure the area to cover, and prioritize UV-treated polyethylene with a mesh size small enough to block the target but large enough to allow pollinators and light through.
Different pests require different mesh sizes and netting types. For birds and deer, use a coarse net with 1/2 to 3/4 inch mesh. For insects like cabbage moths, carrot flies, or aphids, choose a fine mesh of 0.8mm to 1.0mm. If you need to block all flying pests, go for insect netting with sub-1mm holes. For frost protection, use a row cover fabric instead of netting. Always match the netting to the specific pest you have observed in your garden; otherwise, you may waste money on a product that does not solve your problem.
Calculate the square footage of your garden bed or row. Add 30% to 50% extra for drape and anchoring. For example, a 4×8 foot raised bed needs a net at least 6×10 feet to allow slack and proper sealing along the edges. If you are covering a fruit tree, measure the canopy width and height and add 2 feet on each side. Use stakes, hoops, or a frame to keep the netting off the plants; direct contact can lead to rubbing and pest access through the mesh.
Most garden netting is made from polyethylene (PE) or polypropylene (PP). PE is more durable and UV resistant. Look for a UV stabilizer additive; this prevents the net from degrading in sunlight. A net without UV treatment may last only one season. Good quality netting should have a lifespan of 3 to 5 years. Avoid netting that feels brittle or has a strong chemical smell, as it may leach or degrade quickly.
Fine mesh (0.5mm to 1.0mm) blocks small insects but reduces airflow and light by about 10% to 20%. This can be a problem for sun-loving crops like tomatoes or peppers in hotter climates. Coarse mesh (1/2 inch or larger) allows full light and airflow but only stops larger pests. For pollination, you may need to remove fine netting when flowers bloom or use a net that can be opened. No net is perfect; you trade off protection against light and air.
Easy installation saves time and frustration. Look for netting with reinforced edges or grommets. Use ground staples, sandbags, or bricks to secure the edges. For raised beds, a simple hoop frame with netting draped over and weighted down works well. For larger areas, consider a walk-in tunnel or a netting system with a zipper door. Avoid netting that tangles easily; some products come with a carry bag and instructions for folding. Check reviews for customer feedback on tangling and durability.
Q: Can I use garden netting for frost protection? A: No, standard netting does not provide frost protection. For frost, use a row cover fabric (floating row cover) which traps heat and blocks cold. Netting is for pest exclusion only.
Q: How do I clean and store garden netting? A: Shake off debris and hose down with water. Let it dry completely before folding to prevent mold. Store in a cool, dry place away from rodents. Most nets can be folded and reused for several seasons.
Q: Will fine insect netting keep out bees? A: Yes, fine netting (sub-1mm) will block bees. If you need pollination, either remove the netting during flowering or use a net with larger mesh that allows bees to pass but still blocks larger pests. Alternatively, hand pollinate or introduce bumblebees inside a closed net.
