1. Moisture: Begonias prefer moist, well-drained soil. They thrive in environments with higher humidity. Petunias, on the other hand, are more tolerant of drier conditions and can even handle some drought.
2. Light: Begonias generally prefer shade or partial shade. Too much direct sunlight can scorch their leaves. Petunias, in contrast, love full sun and will produce the most vibrant flowers when exposed to direct sunlight.
