Yes. Yes you can!
Bird netting can last for years. That said, some people like to cut holes in it to allow taller plants to grow through while still maintaining a good level of protection from critters. If that’s your style, you may go through more netting than if you were leave it in tact. When you do need to replace the netting, it is available at many big box stores, local hardware stores, and garden centres.
Plastic sheets that are included in our Hoop Tunnel kits will also last for years. If small holes or tears appear, simply tape them up with clear tape. We suggest taping from both sides of the plastic for a stronger fix.
When you do need to replace the plastic, rolls are available from big box stores, usually in the paint section where you would find tarps and canvas drop sheets, or in local paint and hardware stores. Choose the medium grade thickness. The heavy grade (often referred to as Super-Six) blocks some sunlight, and the light weight stuff is too fragile.
