| Question: | "We have recently read a number of articles in various trade publications condemning annual meadow-grass as a species with serious disadvantages as far as golf greens are concerned. We were therefore disturbed to hear from our greenkeeper that our greens contain a high proportion of this grass. Do you consider annual meadow-grass a serious disadvantage and, if so, how can it be controlled?" |

| Answer/Response: | "Annual meadow-grass (Poa annua) has some advantages in that it rapidly covers bare patches and provides some kind of cover on poor soil conditions where better grasses tend to be thin and sparse. It does, however, have serious disadvantages. Fertilizer requirements are high, particularly for phosphate and potash, and it is susceptible to Fusarium patch disease. It also has a tendency to deteriorate rapidly in the autumn, particularly if the weather is harsh, and is slow to recover the following spring, giving a type of golf green which is in good condition for only a limited period each year. Annual meadow-grass is often associated with poor soil conditions - excessive wetness and a tendency to thatch accumulation. It can sometimes be difficult to decide if the meadow-grass is causing the thatch or vice versa. Control is best achieved in the long-term by maintenance aimed at encouraging better grasses and improving soil conditions. The use of excessive quantities of nitrogen and particularly phosphate fertilizer should be avoided - there is nowadays a tendency for most clubs to use far too much fertilizer, particularly phosphate. Watering should also be strictly controlled as watering favours both annual meadow-grass directly and, by encouraging wet, poor soil conditions, indirectly as well. Any measure aimed at improving soils - sandy compost top dressing, thatch removal, adequate aeration and the promotion of good drainage will all tend to encourage the desirable bent and fesue grasses at the expense of annual meadow-grass. Liming should be avoided in most circumstances as the more acid greens tend to have less annual meadow-grass in their make-up. The botanical composition of greens containing a high proportion of the weed grass can therefore be gradually changed by careful management over a period of years." |
