Blueberry plants require more care than most fruit crops, making those sweet, juicy berries especially precious. Unfortunately, the birds love blueberries just as much as you and can devour an entire crop in no time. Scare tactics such as aluminum plates and metal strips are usually ineffective, according to Oregon State University Extension Service. But a permanent structure is a simple, effective solution.
Measure the area around your blueberry patch. Cut the PVC pipe into four lengths as wide as the blueberry plants with your hack saw. Cut four more pieces of PVC pipe as long as your blueberry patch. Cut four pieces of PVC pipe as high as your blueberry plants plus 12 inches.
Attach the three-way joints to the long PVC pipes. Attach two short PVC pipes to two long PVC pipes at the joint. Continue attaching the PVC pipes with the joint until you've created either a rectangular or square-shaped box, depending on the measurements of your blueberry patch.
Lay the netting over the PVC box so it extends all the way to the ground. Secure the netting by tying plastic ties through the netting and the pipe every 3 inches. Insert landscape pins through the netting into the soil every 3 inches so birds can't scoot underneath the netting.
