Nycon Floating Plant Protector NYCRFID2 -round; 18"" deep &#9989; KEEPS PLANTS SAFE FROM FISH: The Nycon Floating Plant Protector NYCRFID2 protects all parts of your pond plants. Its netting prevents the plants' submerged stems and roots from becoming food for koi and other fish. Because its top ring floats, the protector also prevents the plants' emergent leaves from being nibbled by fish at the water surface. Slip the netting over a pond planter for full protection of tender emergent stalks and roots. &#9989; PERFECT SIZE: Measuring 2 feet in diameter at its top, this round, floating protector offers plenty of room for one or more plants. The protector is 18 inches long or deep, accommodating the lengthy stems of water lilies, lotus and other plant varieties. Using its drawstring makes the plant protector funnel shaped, with its top wider than its bottom. &#9989; PERFECT COLOR: The plant protector's black color reduces its visibility in a water feature. It allows the focus to remain on your beautiful plants. &#9989; CAN CONFINE PLANTS TO A SPECIFIC AREA: In addition to holding aquatic plants, this protector can be used to keep the plants in a certain part of the pond. Simply anchor or tie the protector to the pond bottom or bank. (Anchor and tie are not provided.) &#9989; REDUCES POND CLEAN-UP: Because this netting basket holds an entire plant, it keeps the plant's old, lost leaves from floating throughout the water garden. That feature reduces algae in the water and makes collecting the spent leaves simpler and quicker.
