Ideal for keeping leaves out of the pond year round. Black, 3/8 inch mesh. Cover your pond in the fall with this floating netting to reduce leaves accumulating in the pond. Use at other times of the year to keep fish in, cats or other animals out, or to reduce debris blowing into the pond. While the netting is designed to be used over a water garden to keep leaves, birds and cats out, there are other useful places it can be helpful. Don’t forget to cover your stream, waterfall and disappearing fountain to keep leaves out in the fall. We discovered that using the pond net over our vegetable garden kept moths from laying eggs that grow up to be caterpillars. We had very few holes in our cabbage, broccoli and other cold season crops when we covered them!
