The very fine dust-like seed of petunias require light for germination. If you grow petunias from seed, start them eight to 10 weeks before planting in beds. They prefer soil with a pH of 6.0 to 7.0. If the soil or the area is poorly drained, you can build raised beds to grow good petunias. Best growth occurs in well-drained, light soil of medium fertility. They will become spindly and have few flowers if grown in shade. Petunias should be planted in full sunlight. They can be used for color masses, borders, containers, hanging baskets or as a seasonal groundcover. Many petunias, especially white and lavender cultivars have a very sweet fragrance. The flowers may be large or small, ruffled, fringed, or double. Petunias can be found in every color of the rainbow in solids, contrasting veins or edges, and star patterns. The size of the flowers varies from an inch in diameter from 5 to 6 inches. Height can vary from 6 inches to 18 inches.
