These tender herbaceous perennials come in a variety of colors, shapes, sizes and forms. Although flower size differs among cultivars, you can produce larger but fewer flowers by disbudding. Keep the large terminal bud in the center of each flower cluster and remove the rest of the flower buds from each shoot. The remaining flower bud will produce an extra-large, showy flower. To produce mums with a multitude of flowers, pinch them back when the new growth is four to six inches tall. Continue pinching them throughout the summer months up to August 1, whenever the new shoots are three to five inches long. Repeated pinching will produce bushy, mounded plants that will be blanketed with flowers in the fall. Chrysanthemums naturally bloom during the shorter days of late summer and early fall, which extends the flower garden season up to the first heavy frost. Colors cover the entire spectrum in virtually every shade except blue. If you'd like to match the colors of hardwood leaves, choose yellow, rust, red and bronze-colored mums. If you'd like to use mums as accent plants, consider white, pink and lavender-colored ones. Besides enjoying them outdoors, bring some inside as long-lasting cut flowers to brighten your home for several weeks. Garden mums are easy-to-grow perennials. Choose a fertile, well-drained sunny location with at least a half day of sun. Always water freshly planted garden mums, and keep a watchful eye out for dry spells. Water as needed to keep the plants from wilting. Maintain a two- to three-inch layer of compost to reduce water evaporation and suppress weeds. Mums are susceptible to stem rot, powdery mildew, aphids and spider mites. Should you these or any other problems, contact your local Extension agent or Master Gardener for recommended control measures. -- Bob Polomski, Clemson Extension consumer horticulturist. ******************************************* If you have gardening questions or comments, write to Agricultural News & Publications, A-101 Poole Agricultural Center, Box 340311, Clemson University, Clemson, S.C. 29634-0311 END
