Is coco coir sustainable for long-term gardening?
I've been using coco coir in my landscape design projects in my local community for the past couple of years, and I appreciate its benefits, like aeration and water retention. However, I'm curious about its long-term impacts on soil health and sustainability. I'm aware that coco coir is a renewable resource, but are there any drawbacks I should be aware of when using it continuously? I've attempted to balance its use with compost and organic amendments, but I'm concerned about future soil quality. What insights do you have regarding the sustainable use of coco coir over time?
