Answer: You can plant plants of Broccoli rabe that have been hardened off about two weeks before the last frost occurs. You can plant the forsythia and the daylilies in the spring. However, there may be a problem if you want to interplant day lilies among bulbs you've already planted. Do you know exactly where the bulbs are? It would have been better to plant the day lilies first and then plant the bulbs among them.
