Gardening

I'm thinking about buying a few fabric pots and would like to hear some user experiences.

But my main concern is sustainability.

Does anyone have experience using them outside at harsh conditions, e.g. UV radiation, freezing temperatures, all year around?

1. Can you wash them in the washing machine? Are they hard to clean?
2. How well do they work for perennial plants in winter? They are pretty airy after all, does this insulate the cold, or makes it even more destructive for the hibernating roots?
3. How long do they last under those conditions? Will they disintegrate after some time and shed microplastics?
4. Do they dry out significantly faster than regular pots? How is the water consumption?
5. When using coco coir, should I use less perlite?

Thanks a lot!
