butterfly bush

Question

Mine never bloomed! What did I do wrong?

Answer 1

This could be a case of too much Nitrogen in the soil. Excess Nitrogen can lead to lush green plants and little or no flowers.
A soil test will help you determine if this is the case.
Your nearest County Extension Office can help you with a soil test for a small fee.
You can add phosphorous to promote flowering. Bone Meal is a good way to add phosphorous.
