The other main advantage of Polythene Pots when compared to traditional plastic plant pots is that they are very easy to store. When supplied they are folded flat so you can store lots of pots in a very small space. Once they have been used, you can wash away any soil and fold them flat again ready for when they'll be needed again.
Made from flexible black plastic, the Polypots have punched-out drainage holes in the base for free drainage. When opened up and filled with compost they form a square, free-standing pot.
