Baskets

I've given up with everything other than plastic FC. The birds destroy the liners and use it for nesting material. For years I've cut up compost bags to line baskets and face the black side outwards. When I've filled the baskets with soil I put about half a dozen pencil width holes in them for drainage. So yes, the plastic on its own is enough.

 

@fat controller......The plastic will stop them drying out so quickly as well, but they will need the holes to take away the excess. I said half a dozen holes above, sorry, you'll probably need more than that. I was thinking of the baskets screwed to the front of my place which are semi circle. Unfortunately I can't have baskets on hangers the wind tosses them about to much.

Yes, the plastic will give more compost room. When I line my baskets, which is rarely when using plastic, I cut them quite a bit larger than the basket and then just overlap inside creating sort of pleats for shape as I put the compost in, this will hold them in position. Any excess at the top edge after filling can be trimmed off.

 

If you have a pound stretcher near you they are selling these

Might give them a try
I use compost bags as liners too

 

I think the only advantage with coir is it looks nice. To buy new liners for my bowers and baskets costs a fortune. Poundstretcher sell coir liners pretty cheap though , but don't have 14" ones in at the moment. I line my coir basket liners with plastic bin liner , it helps retain the water and protect the coir a little.
