Q: My mother has an old flower plot containing phlox, sedum, and many other perennials. The bed is in decline and needs to be rejuvenated. Considering the variety of plants, what needs to be done?

A: Wait until April and observe the bed for emerging leaves of the various flowers. Once you know where each plant is growing you can transplant the clump to a better spot. Keep an eye on the area in winter; don’t allow weeds to grow so thickly that they obscure the green leaves of the perennials in spring.
