Reseeding

Key factors for reseeding
Irrespective of the method of grasslamd  improvement there are a number of secrets to success.
  • Rectify any soil compaction by either ploughing or subsoiling.
  • Correct the soil acidity (pH) and fertility based on recent soil analysis.
  • Sow seed into a firm and fine seedbed
  • Don’t bury seed too deep - aim for 6-12mm.
  • Lightly roll after broadcast sowing to ensure good seed contact with the soil and to reduce water loss from the soil surface.
  • Control pests (leatherjackets, slugs) and weeds (chickweed, docks) if necessary.
  • Graze frequently with lighter stock such as sheep (if you haven't got any light stock use a mower).
Once a reseed has been established it must be continually monitored for signs of pest damage, especially slugs and leatherjackets and treated as soon as damage is noticed.  The new reseed should also be monitored for weeds, e.g., chickweed, which can quickly smother the new grass.  Grasses should have at least two leaves and clover should have 3 leaves before spraying.  
The new grass should be grazed as soon as roots are strong enough (roots remain in the ground when the plant is pulled). Early grazing is important to allow light down to the base of the sward to encourage tillering. Frequent light grazing is best to establish a dense, even sward
