lining pond baskets

Guernsey Donkey2

Do you line your submersible pond baskets? Some say yes, and others don't bother.  Don't the roots make their way out of unlined baskets and eventually become a nuisance in the pond if you don't line the baskets? If you do line them, do you use Hessian or some other type of liner?

Depends on the plant. My water mint worked through the liner so I just lift it every so often and hack it back.

I used hessian to line mine but the plants eventually escaped and wandered further and the hessian also biodegrades after a few years.

I thought of using plastic with a few small holes punched in to it so that the water can escape but hopefully not the roots. Using old plastic bags as liners would be far cheaper, readily available and would not biodegrade.

I've used the mesh planting baskets and aquatic compost topped with washed gravel. I've had no problem with the compost leaking out of the baskets. We haul the pots out of the pond every couple of years or so, depending on how vigorous the growth is, and split and replant. there's been no need to line them with anything.

Following up - I have now planted two baskets for the pond, immersing them into a galvanized tub of water until the pond is ready.  I used garden soil (not particularly enriched & no food or chemicals recently put into it). I lined the baskets with old polythene sheeting although I realize that determined roots will penetrate this. I topped the soil with plenty of pretty pebbles. Once immersed into the water no soil escaped.
