How to grow petunias
Petunias can be raised from seed, purchased as small plug plants to grow on or purchased as gardener plants. Petunias are soft and do not tolerate any frost at all, so you must not plant them outside until late in the spring or early summer.
Petunias needs a good rich soil to perform well. Prepare the soil in the boundaries by mixing lots of well -rotated compost or soil conditioner, before planting. For pots and containers, Petunias does the best in peat -free, multifunctional potting compost. For raised containers such as hanging baskets and window boxes exposed to drying sun and wind, choose a compost containing water holding granules.
