Petunia seeds do not require any treatment (eg soaking, stratification) before sowing. Petunia seeds grow best when they are raised in trays or other containers and transplanted to the garden once established. Fill trays, punnets or jiffy pots with a good quality seed-raising mix, or use soil starter pellets.Cuttings carry the risk of virus transmission, which can impact crop quality. In contrast, seed-grown petunias significantly reduce this risk, offering a more stable production method. Seeds are also more durable and easier to store, reducing the risk of spoilage during transport.
