I have already planted some petunias in the flower beds but i don't particularly like them there. Would the petunias survive being moved a second time into pots?
Your petunias will probably be just fine if you transplant them again, they're pretty tolerant plants. Of course water well when you transplant anything and rooting fertilizers like root n grow can help reduce transplant shock. Never use a high nitrogen fertilizer on anything newly planted. Nitrogen is the first number in the three numbers on fertilizer(4-12-12 for example). This article may help
