POTR Copper Stem


The POTR Copper Stem, utilising the natural antimicrobial properties of copper, has been designed to extend the life of your flowers. It simply nestles in amongst your flower stems - to act as an antimicrobial rod, actively killing bacterial build-up in the water, the number one killer when it comes to premature flower withering. 

Pair the POTR Copper Stem with the POTR Letterbox Vase to create the optimal conditions to keep your flowers thriving as long as possible

POTR Copper Stem


How It Works

POTR Pots are delivered flat pack through your letterbox with the smallest carbon footprint possible. After popping into shape the wicking cord enables your plant to self-regulate its own water intake - no more unhappy plants!

Self-watering Innovation

Take the guess work out of plant care. The cotton cord functions as a wicking straw, transferring water from the reservoir in the base of the pot to the soil surrounding your plant. Built into all POTR Pots.
