This is what has worked for me. I use baskets lined with weed blocking
fabric (no pesticide treated stuff). I use these for lilies and some of my
marginals. I find that the baskets allow for some circulation, because the
sandy soil I use doesn't stink like what comes out of a closed pots. I use
holeless closed pots for cattails as they have sharp runners and it has
been suggested that those runners might go right thru a liner. I imagine

I can confirm that cattail roots will penetrate a liner. My pond was
dug 20 years or so ago and is lined with a polyester-reinforced
synthetic rubber material from BF Goodrich. It was typically sold by
the acre for lining retention ponds, etc. and is pretty tough stuff.
Several years ago my wife had thrown a cattail head or two into it.
There was a pretty good stand of them when I decided to have a water
garden instead of a liquid compost pile. I had to patch 2 or 3 holes
where the cattail roots had gone through,

On the original topic, I have trouble understanding why one should use
closed pots. Seems like you would need the circulation to get
nutrients to the plant. Anyway I don't use closed pots and most of my
plants are doing fine.
