Re: Vic -- Iris tridentata

>You asked are there any problems with the tubs freezing in the winter.  It gets down into the teens some winters here in >Crawfordville, Florida and the water surface in the tubs may freeze.   However, the tubs and I. tridentata come through >fine.  You also asked about growing I. virginica and I. pseudacorus in no-drainage tubs.  I grown both in no-drainage >tubs and they love it.  The only thing I do differently with these species is that I add fertilizer usually once a year.

 

Vic,

     Actually, it was me who asked about Iris virginica and Iris pseudacorus in the no drainage tubs.  I very tempted to try it.  I was asking you and Ken about the freezing.  There is an area along US 41 in the western part of Florida that is known as the âcold troughâ in winter due to our colder nights.  The temperature starts falling fast in late afternoon then and night freezes are common.  This is a USDA Zone 8b climate, so we do go into the teens some.
