| Question: | "Annual bluegrass is giving us considerable trouble in our greens. Some greenkeepers object to it and try to get rid of it while others do not seem to mind it. What are your suggestions?" |

| Answer/Response: | "Annual bluegrass makes up a large percentage of the turf on some of the most famous golf courses in the country. It is at its best in spring and fall. When a green contains also bent grass, there is a gradual change in late spring and early summer from a large percentage of annual bluegrass to a large percentage of bent. The bent predominates during summer, and in fall the annual bluegrass returns in abundance. Greenkeepers who have mixed annual bluegrass and bent greens have varying success in bringing the bent grass in as the annual bluegrass disappears in hot weather and in keeping the annual bluegrass in good condition during the seasons when it is most in evidence. Apart from general observations, little is known regarding the best method of culture for annual bluegrass. It is possible to have very fine annual bluegrass putting turf in spring and fall. The grass adapts itself fairly well to most cultural methods. Often it is necessary to cut annual bluegrass greens twice a day. The grass requires frequent watering, but not to the extent of keeping the soil saturated. Also frequent light applications of fertilizer are advisable; it is better to apply small amounts of fertilizer every two weeks than large amounts once a month. If the annual bluegrass produces a great deal of seed and becomes bumpy, the turf can be improved by dragging it with steel mats, followed by close cutting, in order to eliminate as many of the seed heads as possible. Also a light top-dressing at that time will improve the putting surface. The undesirable feature of annual bluegrass is that it may become weak or even die out very quickly in summer. The fact that it can not be depended upon to provide good turf in certain sections of the country through summer seems important enough to some clubs to endeavor to prevent it from becoming established in their greens, particularly by paying special attention to means of preventing this when the greens are first planted. No doubt large quantities of seed of annual bluegrass are carried to putting greens through topdressing material. Also seed of it may be washed from plants on higher elevations, to a putting green, unless sand traps or grassy hollows are provided to catch the surface wash before it reaches the green. When annual bluegrass has become thoroughly distributed in a putting green and makes up a large percentage of the turf, there is no practical method of getting rid of it apart from removing the turf and replanting the green." |
