Non Blooming Impatiens
I have bought and grown impatiens for many years and never had any problems. This year they're planted in pots using Miracle Grow Moisture Control potting soil, as I am now in Nashville, TN. They have plenty of buds but are not blooming. I used Miracle Gro starting fertilizer and then regular Miracle Gro fertilizer since then every other week, but nothing except buds.
The most common reason is that there is not enough light. They do need shade but bright shade..........if in too dark of a location, they often bud but do not blossom. Hope that helps.
