Q.coco liners
At the end of the season, can the coco liners in hanging baskets be removed, washed out and stored and reused next season?

Coconut coir liners are considered to be incredibly durable and can be reused for many years if carefully handled. I would hope that you would get at least 3 years out of them with year-round use. So, yes, they can be washed out, dried and stored for reuse next season.
