I recently came across someone who also grows tropical plants. Doesn't have any plumerias, but said that it's always best to put screens at the bottom of the pots to prevent soil coming out the drain holes as well as keeping critters from entering the drain holes.
He also said a paper towel works too, but it will eventually turn brown and mold.
Just curious if anyone else does this or something similar or has better insight on it?
Thank you
