Growing petunias can offer long term color in the summer landscape and brighten dreary borders with lovely pastel colors. Proper petunia care is simple and easy. While petunias will grow in a partially shaded location, a fuller and more abundant bloom is produced in full sun.Petunias tolerate lots of heat, and are relatively undemanding when it comes to water. Except for "spreading" types, which require frequent watering, thorough watering once a week should be sufficient in all but the worst weather.
