So do you all not worry about the anaerobic yuk that grows in those sealed bottom pots?
Do you all just use garden soil, sand, gravel, or kitty litter, with osmocote or...?
I tried coconut hair stuff on the bottom half of aquatic soil this year in perforated pond pots, with poor results. The coconut hair stuff collapsed under the weight so the pots were only half full of soil. I used the Jobes fruit tree spikes as well, but need a better set-up next year.
Suggestions?
