A plant guard for protecting plants against pest attack. The guard (10) comprises a knitted hose-like net structure which is intended to form a casing around the guard. Connected to the bottom part (13) of the net structure are mutually crossing hang-threads (14) which form the bottom of the guard. A closure thread (17) is located at the other end of the net structure, this thread when tightened gathering together the upper part of the guard. The closure thread (17) is knitted integrally with the net structure and comprises a thread of high surface friction, so as to be self-locking when tension is released. At least one loop (18) formed from the closure thread is attached to the bottom end (15) of an adjacent, corresponding plant guard, such that the closure thread (17) is drawn together when the two plant guards are separated one from the other. The application also describes a method and a circular knitting machine for manufacturing such a plant guard.
