Seagrass identification problem
I've been looking around for any type of woven baskets etc to compost the natural fibre material they're made from.
I understand that Seagrass is one such fibre but, while doing a search on Google, I found this information:
"Beware if using excessive amounts of Seagrass as compost: it has a high Boron content that may lead to toxic plant levels, predisposing those who eat them to stomach cancer. Kelp is a better choice."
My problem is, how do I identify Seagrass among all the other natural fibres that are used?
