Poor management allows annual meadow grass to establish itself everywhere and this plant raises its ugly head if the weather is favourable i.e. wet. Autumn has always been a period when annual meadow grass attempts to establish itself in the sward or keep holding its own just before winter. This happens more easily if the sward is open, offering annual meadow grass the chance to establish. That's why it is essential to overseed in good time with RPR or SOS. Furthermore, the sward is then ready for winter with a nice, dense turf and the risk of unwanted annual meadow grass in the spring is reduced.
Breaking through the vicious circle of annual meadow grass
July is usually a warm, sunny month, but August can be wet and a bit nippy so that annual meadow grass can easily take hold in a lot of places. Therefore, many swards get off to a bad start in the new season. Firstly, annual meadow grass causes a lot of bare patches to appear mid-season, then the bare patches are eventually filled in by even more annual meadow grass. Regular overseeding is recommended to break this vicious circle of annual meadow grass. For several reasons, it can be difficult to decide when the time is right for overseeding, but it is important to watch out for when annual meadow grass is in bloom. When it is in bloom, new seeds are formed and this is the ideal time for dissemination of this unwanted plant.
