Manufacturer's Description
Aquascape Aquatic Planters are ideal for all pond plants. The fine porous material allows water in, but keeps soil from entering your pond. The flexible material makes it simple to place the plants where plastic pots will not fit. Aquatic Planters quickly blend in with the rest of the pond. Aquascape planters will not break or crack like plastic planters. Can be molded to fit in tight spaces. Will not break or crack. Keeps soil from escaping.
