Question
Please advise how to care for Crown of Thorns plant.  The leaves are turning yellow....It is still blooming

Answer
I am sorry, but my expertise is limited to the care of African Violets.  This is stated in my profile on AllExperts website.

You can get an answer to your question by visiting the Houseplants site in AllExperts.com and directing your question to Will Creed or Darlene Kittle.  Both of these are master gardeners, and very knowledgeable in the care of all plants.
Good luck.
