Caring for Petunias in Hanging Baskets

Petunias in hanging baskets aren't too different from petunias grown in the ground, but there are still some things that you need to be on top of when caring for them.


Try to hang the petunias in an area with at least 6 hours of sunlight a day so it can bloom at its peak. Rotate the basket every week by 180 degrees so each side receives an equal amount of sunlight.


Petunias need to be watered regularly, especially in the summer heat. If the first inch of the soil is dry, then they need to be watered. Be wary of overwatering, as too much water can lead to root rot or mold.


Petunias may be healthy and grow abundantly, but their leggy overgrowth can cause them issues. Petunias that are too leggy during the blooming season flower poorly and may die prematurely. Pinch back the leggy stems for healthier blooms.
