What is the plant
Petunias are one of the most popular garden flowers for both borders and containers. They are prolific bloomers, although some forms require deadheading to keep them going. However, most petunia varieties will bloom throughout the summer, except in extreme heat. You can find petunias in just about every color but true blue and with growing habits that mound in borders or trail down containers. Petunias have wide trumpet-shaped flowers and branching foliage that is hairy and somewhat sticky. They grow easily when you transplant them to the garden, and this should be done in the spring when the threat of frost has passed.

How to Care for the Plant
Water
While you can get away with watering petunias in a ground deeply once a week, petunias in containers need to be watered more frequently – as often as once a day. Whether they are planted in containers or in a ground, petunias require five to six hours of sunlight a day at a minimum.
Pruning
Prune branches back to a natural fork to avoid leaving unsightly stubs. Cuts bleed if pruned in late winter or early spring so pruning should only be done between mid-summer and early autumn.
Fertilizer
Simply apply the fertilizer around the base of the plant, extending to the drip line. For vegetables, place the fertilizer in a strip parallel to the planting row. Water-soluble fertilizers are faster acting but must be applied more frequently. This method gives plants food while you water.

Sunlight
If your plant is not getting enough light, the most common sign is the yellowing and dropping of leaves, stunted leaf growth, elongated stems, and a dull-green color. If your plant is getting too much light, then its leaves will have singed tips, burned patches, or will be falling off (yikes!).
Soil
Loamy soil is ideal for most garden plants because it holds plenty of moisture but also drains well so that sufficient air can reach the roots.
Temperature
Petunias are frost tender plants that are only hardy in zones with average winter temperatures of -3.9°C (25°F), so they are almost always grown as annuals.
