I grow Epiphyllums as a hobby & last year, decided to use the Eden range of Self Watering pots (from Bunnings) for over 15 of my Epiphyllums.
Whilst accepting the concept of Self Watering pots, I have found over the past months, even though I do not over water & use a (Bunnings) "wet/dry" thermometer; in many instances, the plant stems have begun to rot due to "wet soil" accumulated in & aggravated I believe, by the "cross indentation" in the pot base which allow soil to remain continously wet.
I also have plants in Tuscan Self Water Hanging Baskets (from Bunnings) where although they do have an indentation in the middle, this is far smaller than the Eden product. No plant stem rotting occurred to-date.
So, what is your advice...change over to standard Plastic pots...or...???
