Biwi Bio-Pellets for balcony flower boxes and gardens are made from local cattle manure. Due to the anaerobic fermentation process, the nutrients have a time-delayed but long-term effect. You will get thriving flower beds with sustained growth – both in window flower boxes and in garden beds. Easy to transport, absolutely odorless, and non-smearing. Just work them into the soil– and you're finished! Biwi Bio-Pellets work like a charm!
