When to Use

Apply every 3-4 weeks from Spring to Autumn when the grass is actively growing. For best results apply to the lawn after mowing and remove the clippings for better seed-soil contact.

Best Conditions: apply when the soil is moist and the grass is dry. Do not apply when soil is dry, during freezing conditions or when frost is expected.

How to Use


It is good practice to wear gloves when using the product. Apply the granules thinly and evenly to ensure the same result across the entire lawn. Mark out the areas to be treated.

Handy Tip: 1 parking space = 2 x 5 metres = 10 sq. m

By hand

  • Apply 35 grams per square metre over the marked area

By wheeled spreader

  • Apply at a rate of 35 grams per square metre over the lawn
  • Use the correct spreader setting or calibrate your spreader to apply the correct amount

To Finish

Brush off granules immediately from hard surfaces, decking, clothing and footwear to avoid staining/discolouration. Do not wash as may cause staining. Water in thoroughly after application.

Keep the lawn well watered for at least 2 weeks to help grass seed germination. After 3 days the lawn will become greener and healthier.

Over the following days and weeks, the grass seed will germinate to create a lusher, thicker lawn.

Tips to Feed your Lawn

Feeding and regular maintenance provides the nutrients needed for a healthy lawn that looks green and lush. Also helps to develop a strong root system in your lawn to withstand weather/traffic and to crowd out weeds and moss. Ideally, follow these season treatments for best results:

Spring Feed

Your lawn needs extra nutrition as it starts actively growing. Also itʼs the ideal time to overseed. Combine these two steps by applying Aftercut Lawn Thickener between March-May.

Summer Feed

Lawn gets most use and dry weather takes it toll. Feed your lawn for root strengthening and green results by applying Aftercut Lawn Thickener between June-August.

Autumn Feed

Care taken now will reap rewards next spring. Feed your lawn again for a final boost before winter time for more resistant leaves and roots.
