Application Rates

  • Greening rate 25 grams per square metre
  • Moss control rate 35 grams per square metre

Maximum 2 applications between October and April - Do not apply during rainy weather to avoid loss by leaching

  • As a Winter Lawn Feed: December to February - One to two applications at 25g per m2 to provide beneficial winter nutrients and grass protection. For best greening effect apply during a damp mild spell after rain
  • For late Autumn and Winter Moss Suppression: October to February - One application at 35g per m2 during damp/moist ground conditions or after rain
  • As part of a Spring Moss Control Program: March to April - Apply at 35g per m2 during damp/moist ground conditions one to two weeks prior to raking moss. As this is a low nutrient Winter Feed a Spring Feed will still be required after raking and seeding to promote recovery and aid development of new seedlings.

Yet to use this product since we're still in autumn. However, I have been advised by Lawnsmith this is the best fertilizer to apply over the winter months to newly laid lawn.
