As seen on the Madame Flavour teas website, describing how their special tea bags (“infuser pods”) can be recycled:
Put several used infuser pods in the bottom of a hanging basket or pot, then put the soil over them. When you water the plant, the water is stored in the pods, a natural form of water-storing granule, reducing the need to water.
The same thing for new garden beds – perfect for water restrictions. And the tea puts minerals back into the soil as it breaks down.
Use infuser pods to plant seeds in. It saves on compost and you can plant straight into the ground.
I usually chuck our used tea bags into the compost, but these ideas sound much more creative!
