I have replaced most with a mixture of garden soil, manure, and pete over the last couple years. It drains well, holds moisture.
I have Praying hands, lady fingers, some unknown that have all bloomed and or fruited in the same soil.
Red drawf does well too, but it keeps getting knocked down by the cold before fruiting.
The orinoco's (4 in different areas throughout) just haven't done well.
Not that big a deal, but maybe just one time get close
