new guinea impatiens
My hanging baskets are lush and full but no flowers.
This article will refresh you on the care requirements.
New Guinea Impatiens need evenly moist soil, and are heavy feeders.
Make sure you use a low nitrogen fertilizer; too much nitrogen will inhibit flowers leaving you a lush green plant.
If you have over fertilized, try adding a feeding of phosphorous rich Bone Meal.
