Non blooming Impatiens
Planted Impatiens in full shade about a month ago. They were blooming at the time. Now growing and look healthy but stopped blooming since put in the ground. Never had this problem with them before. Thanks, Sharon 🤔
You could have too much nitrogen in your soil. Excess nitrogen will inhibit flowering.
Don't over fertilize. Use a balanced formulation when you do.
Give you plants an application of phosphorous, which promotes flowering.
Bone Meal is a good organic method to add phosphorous.
