Re: Two more I. tridentata pictures


Ken and Rodney,

 

I grow lots of Hymenocallis and many Louisiana irises (hybrids and species), I. virginica, I. tridentata, various other irises, and crinums in pots without drainage.  All the containers I use without drainage are filled solely with ?top soil? that I buy locally by the truck load.  It is a black sandy soil with a very high organic content and is slightly acidic.  For containers with drainage I use equal parts of this top soil and a potting soil that I also purchase by the truck load.  The potting soil is mainly composted coarsely ground bark.  I mix it with the top soil in order to make the mixture heavier and hold more water so that it won?t dry out so quickly.  I can?t imagine why the tridentata in pots would rot unless the soil is highly alkaline.

Vic,

What kind of medium do you use in your containers? Every time I've tried I.
tridentata in pots it has promptly rotted.
