Rowan County Master Gardeners will host a plant swap and sale on May 1. Open to the public, the swap will begin at 9:00 a.m.; plant sale at 8:30 a.m. The plant swap and sale will be at the Agricultural Center on Old Concord Road. Only perennial plants will be accepted for the swap; however, annuals, bulbs, seeds and perennials will be available at the sale.

     Perennial plants live for multiple years and many such as hostas, daylilies, dianthus and peonies benefit from division every three to four years. As plants mature and become crowded, the bloom quantity and quality decline. Division can also be used to restrict invasive perennials like bee balm, lambs ear and
herbs in the mint family.
     April is an excellent time to divide perennials. Choose a cool, overcast day so as not to shock the plants as they are being transplanted. Several methods of division can be employed depending on the plant characteristics. Use a sharp spade or knife to remove portions of the crown for perennials such as coral bells, ensuring that sufficient roots are available to support each new plant. For other perennials the result is more aesthetically pleasing when the entire plant is dug up and divided into pieces, replanting one division in the original location.  This works well with daylilies, hostas and sedum Autumn Joy. Many other perennials drop seeds (columbine, sundrops, and blackberry lily) so that you need only dig up the wayward plants and relocate them. Creeping perennials like thyme often root sections away from the center of the plant. Carefully dig up the rooted section and disentangle it from the main plant. In all cases, prepare the new location(s) by loosening the soil and adding amendments if necessary. Plant the division at the same depth as the original plant and water thoroughly. It will be necessary to water the new plantings until they are established.  Divide your perennials and bring any surplus plants to the swap. You'll go home with some new additions for your garden.

For those entering the plant swap, the following guidelines apply:
