Jameson Premium Seed 2025 7 BENEFITS OF RESEEDING Overseeding will rejuvenate old leys and introduce more productive species GUIDELINES TO OVERSEEDING A simple, but effective way to improve old pasture Overseeding increases yield and quality and can be achieved without ploughing and minimising time spent out of production. It is a cost effective way of extending the life of a ley by 2-3 years.The best time to overseed is March-September when the soil temperature is above 7°C. Sufficient moisture is vital so avoid May and June when the existing grass growth will smother new seedlings. The main aim is to minimise competition from existing sward. Best results are achieved from using large seed, vigorous tetraploids as used in No.10 REJUVENATOR. • Soil test in good time. Check pH is 6-6.5 • Check for soil compaction, subsoil 50mm below the pan using a sward lifter if needed • Tight graze or cut. • An open sward is vital for good seed to soil contact, scarify in at least 2 directions using a wire tine grass harrow to open up the sward • Drill (no more than 1cm) or broadcast seed, especially clover, immediately at 10kg/acre. • Roll thoroughly using a ring or flat roller, or tread in with sheep (take sheep off after 7-10 days) to get as much seed to soil contact as possible. • Apply slug pellets if necessary • Control weeds (eg chickweed) 4-6 weeks after sowing • Lightly graze with sheep or very young cattle, around 6-10 weeks after sowing, plants 8-10cm tall and able to withstand the ‘pull test’, to encourage tillering. Don’t leave sheep on too long as they will graze too close, causing damage to new seedlings. • Any nitrogen applications should be delayed until the new grass is well established (normally around 4 weeks after sowing). P & K levels should be maintained at Index 2.
