Thank you so much for your suggestions. These fabric pots are strongly pushed as the viable alternative to plastic pots with such a degree, I did not focus on the content of materials. Thank you for snapping me back!
Has anyone tried the Hugelkultur method with large 25-30 gallon smart fabric pots? I was concerned about mold developing as I am in Northern/Central Florida and we get much rain. Also very humid. It would be a great way to fill such a large container.
