Re: CULT: planting in pots

<< Many of you have mentioned planting your more valuable iris in pots 
 when they first arrive.  That seems logical to move to sun when it 
 shifts or shelter from winds.  But doesn't that expose the plant more 
 to the weather in winter since the roots are closer to a surface?

      Irises grown in pots are exposed more to extremes of temperature.  Most 
Irises are very cold hardy, but in cold winter climates, I would recommend 
the pots be grouped together and mulch be put around and between them.
     I am one who grows Irises in containers all the time.  The Louisianas 
and Iris virginicas, pseudacorus, and tridentata are all in kiddie pools sunk 
into the ground.  This is to enable me to keep them moist enough to grow them 
here.  I grow my reblooming Tall Bearded Irises in pots too.  They have done 
fine so far in pots, but they tend to dwindle away if grown in the ground.
      Lastly, I have some plants of what is probably Iris japonica, which is 
tender to cold.  I grow them in pots, so that I can pull them inside on 
nights like tonight, in which a horrific freeze is forecast.
