Question
I have had a large calla lilly in a large pot for at least the last 10-12 years and it has always bloomed around the first of July.  The blooms are huge and usually number 10-12 blooms and they are bright yellow.  This year, I have not had any blooms.  We had a pretty hard winter for the Pacific NW; could this have affected this year's blooms?  The pot has always been left outside through the winter and I usually plant over the top or around the dormant bulbs.

Answer
Hi Tawnya,
Thanx for your question.  If the plant is only growing foliage, wait a little bit longer, it just may be blooming later this year because of the hard winter you indicated in your question.  If it hasn't bloomed by mid-August, allow the plant to continue growing until it goes dormant in the fall then dig it up.  You may need to separate the rhizomes after 10-12 years.  When the rhizomes become too crowded this will cause a reduction or complete absence in blooming.  You can replant the other rhizomes in separate pots or give them a way to friends.  I hope this helps.
