Question:"Are there different strains of Poa annua having different habits? Is it ever an annual plant in this latitude under putting conditions? Our greens seem to be about nine-tenths Poa annua, yet at no time during the past few years have they ever assumed a patchy appearance, such as would result in case a considerable proportion of this Poa annua should die off. In my own experiments with bent turf in its second year, there are clumps of Poa annua which at least lived through last summer and are still thrifty, having quite heavy stems and leaves, and its pale green color is a disfiguration in a dark green turf. If Poa annua dies off every summer there might be a chance of retarding its germination by a heavy growth of bent grass; otherwise there would seem to be no reasonable way to eradicate it."

Answer/Response:"Northward Poa annuna, or at least some individual plants, behaves as a perennial, as a single plant will live one or more years, going through the entire summer season. This seems to occur also as far south as Washington, though rarely; where, however, the great majority of the plants behave practically as winter annuals, dying off in the summer. Where Poa annua is once thoroughly established we do not know of any method of getting rid of it except by hand-weeding at great expense. If, on the other hand, putting greens are weeded free of it at the beginning they can be kept free of the grass at very little expense for weeding. This has been done at the Old Elm course, near Chicago, and we have done the same thing on our experimental plots near Washington without any difficulty, although Poa annua is very abundant here."
