How to Care for the Plant
Water
Petunias are fairly heat tolerant, so you shouldn’t have to worry about watering them frequently. A thorough watering once a week should be sufficient (unless there are prolonged periods of drought in your area). Avoid watering shallowly, as this encourages shallow roots.
Fertilizer
Fertilize petunias monthly with a balanced fertilizer to support their rapid growth and heavy blooming. Double-flowered cultivars enjoy a biweekly dose of fertilizer.
Sunlight
Petunias need full sun or they will become spindly. They don’t tend to flower well in shade.

Temperature
The annual or bedding petunias can be grown from seed sown indoors with warmth in spring in cell trays, seed trays or small pots at a temperature of 18-24°C (65-75°F).
