Answers To Landscape, Gardening At Ag Progress ROCKSPRING (Centre Co.) This year's long winter and cold spring damaged many landscape plants. Whcthfcr you’re a homeowner, gardener, or professional grower, Penn State faculty and cooperative extension agents can help solve your plant problems at this year's Ag Progress Days, Aug. 13-15. The Landscape, Lawn and Garden Tent will be open from 9 a.m. to 5 p.m. on Tues day and Thursday and from 9 a.m. to 8 p.m. on Wednesday. Advice will be available on in door and outdoor plants, turf, flowers, tree fruit, small fruit and vegetables, as well as control of plant-dam aging insects and other pests. Visitors may bring in plant samples for the experts to examine. These samples can be disposed of at the tent “To get a clear idea of the problem, we need a large sample in good condition," said Dr. Gary Moorman, profes sor of plant pathology. “It’s best to bring sam ples that represent vari ous stages of the prob lem, and to bring in sects in jars, since damage alone may be hard to diagnose." Penn Slate’s Ag Pro gress Days features more than 500 acres of educational and com mercial exhibits, tour, and machinety demon strations.
