Posted By: lizziecatI use Miracle Gro moisture control potting soil. My impatiens thrive on it.I had good luck with this potting soil last year as well.
Posted By: bobkImpatiens are shade annuals, as pointed out above. Putting them in the sun is like sending Nicole Kidman to the beach without sunscreen.

I was doing great this year, with the healthiest, firmest, fullest plants ever, until this week. The humidity just saps the life out of them (i've noticed its more about humidity than the heat. Anybody else make the same observation?)
This year, since we have a new baby, i even tried the diaper trick of lining the bottom of the pot with a diaper to keep in more moisture, but i'm not convinced its working.
