How do I care for a Night Blooming Cereus also known as Queen of the Night (Catus Family)?

Mine is 6 years old and has never bloomed. I am not sure of the type of soil, moisture level, lighting or fertilizing. I understand that their bloom measures 8 to 12 inches in diameter, lasting only about 6 hours, emitting a vanilla-like perfume.

Reply:wow, you've got yourself a highly protected native of Arizona. Your night bloomer does not have roots like most plants, it has a big tubor, like a big raddish for roots. Native night bloomers usually grow under the protection of Arizona desert trees. It likes semi shade, but will adapt to full sun, but may tend to sunburn in the summertime. It will grow in a big pot, or you can plant it in the native soil with a little mulch mixed in. Make sure that where ever you plant it that it has good drainage, you don't want to rot it's tubor type root. Water once per week in the summer, once per month in the winter. No fertilizer needed.
