How to care for Petunia plants? 

1.Location :-

Petunias grow best in warm weather, with an ideal temperature range of 55–80°F.

2.Sunshine :-

Petunias need at least six hours of direct sunlight per day to produce their best blooms. They thrive in full sun, and will become spindly if they don't get enough. 

3.Soil :-

The soil should drain well and not stay overly wet, especially in containers. The soil should also be moderately fertile to promote the best growth.

4.Hydration:-

Keep the soil consistently moist, but not soggy. In containers, water petunias just about every day.

 Such as botrytis blight, powdery mildew, and crown rot, which can cause parts of the plant to die and rot. Such as bacterial leaf spot, aster yellows, and some types of fasciation, which can easily spread in overcrowded plantings. Can cause light and dark green mottled areas, mosaics, and crinkling of leaves.
