Question
Susan,
I am raising a Florist Gloxinia.  I have grown it through several cycles.  The problem I am having is that the leaves are misshapen and/or they curl downward at the outer edges.  What could be causing this?
Randy

Answer
Hi Randy,

This is a fairly common problem in Gloxinias especially during winter, when they require less water, so there is less leaching of soil nutrients.  Gloxinias are very sensitive to ammonia, so avoid all forms of ammonicial nitrogen for awhile.  Increasing the PH (potential hydrogen) of the soil might be called for.  Get a PH test kit from your local nursery.  They are inexpensive - usually around $5.  Here are a couple of good links on Gloxinias and Nitrogen.
