Watering. Water petunias when the top inch of soil feels dry. Avoid letting the soil stay soggy, as this can cause root rot. During hot weather, more frequent watering may be needed.
Fertilizing. Feed petunias every two weeks during the growing season with a balanced, water-soluble fertilizer to support continuous blooming.
Petunias are easy to grow and thrive in sunny spots with well-draining soil. They need regular watering but avoid waterlogging. Deadheading spent flowers helps encourage more blooms. They are generally low maintenance and suitable for beginners.

Petunias can cause mild allergic reactions in some people, especially those sensitive to pollen. The main trigger is the pollen released by the flowers, which may cause sneezing or itchy eyes. To reduce exposure, avoid handling the flowers if you are sensitive and keep the area well-ventilated.
Common problems
Petunias can suffer from fungal diseases if overwatered or if air circulation is poor. They may also attract aphids or caterpillars. Wilting usually indicates underwatering or root problems.
Uses
Primarily grown as an ornamental plant for colorful garden beds, borders, containers, and hanging baskets.
Notes
Regular deadheading (removal of faded flowers) promotes more blooms. Petunias can be grown indoors if placed in a very bright spot but perform best outdoors. Avoid overwatering to prevent root rot.
