Answer: You didn't mention whether you took cuttings or are propagating from seeds and that would make a difference in how you take care of them and when they will be ready to go back into the ground. Aside from that, your ice plant is a perennial and can go into the ground as soon as it develops roots (usually 4-6 weeks). The petunias and impatiens are annuals and they will die when the weather turns cold. Neither one is suitable for growing indoors. They just won't perform well. Wish I had better news for you!
