Method of manufacturing a plant receptacle wherein the following steps are performed: a) a PLA thread is co-extruded with a flexible aliphatic polyester, said flexible aliphatic polyester comprising 10 wt% to 30 wt% bamboo material, such that the flexible aliphatic polyester covers the PLA thread, thereby creating a weldable biodegradable thread； b) using said weldable biodegradable thread in a woven or non-woven process, making a permeable sheet material； c) continuously forming said sheet material into a continuous receptacle, by bringing the side edges of said sheet material into contact and welding said side edges together； d) cutting said continuous receptacle in predetermined lengths thereby creating separate plant receptacles.
