An annual reseeding programme should be part and parcel of grassland management. It does not have to be a big area that is reseeded each year. Instead, the little and often approach is a much better option as it is cheaper and it is easier to manage. Just like in cattle breeding when you change your stock bull for a young bull with new bloodlines that will deliver faster growing calves, reseeding will introduce newer varieties of perennial ryegrass that can yield more grass from similar levels of inputs.
But before you decide to reseed an underperforming paddock, there are a few things to be considered. Simply ploughing a field and sowing out again will not guarantee a successful reseed that can double your grass growth. Instead, doing a bit of preparation planning will increase the chance of the new sward performing over a prolonged period of 10 to 15 years.
