Petunia originated in South America. Petunia is an annual plant. Petunia needs at least five hours of sunlight every day. Petunias need well drained but moist soil. Keep them away from rain. Petunias cannot tolerate heavy rain, but need a lot of sunlight. Water when the soil gets dry. To improve flowering remove the flower stalk (Peduncle). If you do not remove the stalk the plant starts to seed, and once it seeds the life cycle of the plant ends. The bloom time starts from Summer and goes till autumn. Petunia comes in may different colors for example White, Red, Purple, Pink, Yellow, Burgundy, light purple, Purple-lavender, Lime Green, black berry. Petunia seeds need light to germinate, so just press the seeds in soil but do not cover the seeds. They need 7 to 21 days to germinate. Botrytis blight frequently affects Petunias following damp cloudy weather.
