Pond netting can protect your fish from predators, such as raccoons, cats, dogs and birds like blue herons and egrets. Pond netting also prevents leaves and other debris from falling into and contaminating your pond. Many varieties of pond netting are available, with different mesh sizes. A good mesh size for pond netting is 3/8 inches or no larger than 1/1 inch. Unfortunately, pond netting doesn't come with anchoring devices, so you'll need to improvise.
Stretch and lay the netting across the pond. Place rocks or landscaping pavers on top of the netting around the pond to secure it. You can also drive garden stakes into the ground around the pond to hold the netting in place.
Inspect the netting to see whether it is hanging into your pond and touching the water or plants. You don't want the netting to touch the water's surface because your fish could become tangled in the netting.
Insert PVC pipes in the ground around your pond, spaced about 3 feet apart, to prevent the netting from hanging into the water. Drape the netting over the PVC pipes and secure the netting by placing rocks or pavers on top of it where the netting drapes to the ground behind the pipes.
Clean the netting once per month. Remove the netting and flip it over. Shake off any debris, such as leaves, twigs or snow. Lay the netting back over the pond.
Purchase pond netting that has added UV inhibitors to extend its lifetime. You may pay a little more money initially, but you won't have to replace the netting as soon as you would the netting without UV inhibitors.
Don't allow the netting to touch your pond plants. Place stakes or PVC pipes around your shoreline pond plants to prevent the netting from touching the plants.
