Metal containers without drain holes
So! My mom brought over these adorable containers.
They are metal, and without any drain holes. I am afraid that if I plant directly in them, they will rust, as well as collect way too much water.
Where would I get plastic liners for these? The liners wouldn't drain either though, so how do I solve this problem of no draining? I just don't get it. How do you plant in things with no drainage holes without having plants rot?
Could I leave these adorable pots outside, or would they just rust? Maybe they are for indoors. Not a clue.
