Question: My impatiens’ leaves are rolled under and the plants have quit blooming. What is wrong?

Answer: That sounds like high summer temperatures.  Impatiens grow and flower best when temperatures are in the 70s and 80s.  They mysteriously slow in their flowering when temperatures consistently hit the high 90s, generally by mid-June.  If you can keep the plants moist over the summer they often will resume blooming in September.  You may want to shear them somewhat to keep them compact.  Watch, too, for spider mites over the summer.
