FAQs

When is the best time to apply Aftercut Moss Killer?

The best time is from May to mid-November when both the grass and moss are actively growing. Apply on calm days when the grass is dry but the soil is moist. Avoid applying during drought, frost, or high winds.

How long after application can children and pets use the lawn?

Children and pets can safely use the lawn once the treated area is completely dry after application.

Can I use this on a new lawn?

No, this product is only suitable for established lawns that are at least one year old.

How much product do I need to use?

Apply at a rate of 32 grams per square meter. It's important not to overdose the lawn.

What should I do if it doesn't rain after applying the granules?

If no rain falls within 48 hours of application, water the granules into the lawn.

How soon can I mow the lawn after application?

You can mow the lawn 3-4 days after application. However, do not use the first three clippings for mulching unless they have been composted for at least six months.

How long should I wait before sowing new grass seed?

Wait for at least six weeks before sowing new lawn seed in any patches that have been treated with this moss killer.

What should I do with the dead moss?

Between 7 to 14 days after application, rake out the dead moss to allow the grass underneath to recover and grow.

Troubleshooting

Moss is not dying after application.

Ensure the product was applied at the correct rate (32g/m²) and that conditions were suitable (active growth, moist soil). Re-check application instructions and wait the recommended time before assessing. Reapplication may be necessary after 6 weeks if moss is still present.

Product seems to be burning the grass.

The product may have been overdosed or applied during unsuitable conditions (e.g., drought, high heat). Ensure correct application rates and follow the weather guidelines strictly. Avoid applying directly to grass crowns.

Granules staining paving slabs or patios.

Brush off any spilled granules from hard surfaces immediately after application (within 0-1 hour) before they have a chance to react. Do not wash them off with water, as this can spread the staining.

Difficulty in spreading granules evenly.

Use a garden spreader for more uniform application. If applying by hand, divide the lawn into sections and use a consistent amount for each section. Ensure the granules are dry and free-flowing.

Setup, Compatibility & Care

How to Use:

  1. Check Lawn Age: Ensure your lawn is at least one year old.
  2. Check Conditions: Apply only when grass and moss are actively growing, on calm days, with dry grass and moist soil. Avoid windy, drought, or freezing conditions.
  3. Measure Area: Determine the size of the area to be treated.
  4. Determine Amount: Apply at a rate of 32g per square meter. Do not overdose.
  5. Application: Wear gloves (recommended). Mark out the treatment area. Spread the granules evenly. If using a wheeled spreader, check its settings for accurate distribution.
  6. Avoid Contact: Prevent granules from contacting plants and hard surfaces.

Aftercare Instructions:

  • 0-1 Hour: Brush off any granules that have landed on hard surfaces (patios, driveways) to prevent staining. Do not wash the granules off with water.
  • 48 Hours: If no rain falls within 48 hours, water the granules into the lawn.
  • 3-4 Days: Mow the lawn. Do not use the first three mowings for mulching unless they have been composted for at least six months.
  • 7-14 Days: Rake out the dead moss to allow the grass to recover and grow.
  • 6 Weeks: If moss regrowth occurs, a second application can be made, but wait at least six weeks between treatments. Do not sow new lawn seed in treated patches for at least six weeks.

Compatibility:

  • Suitable for established lawns.
  • Keep people and pets off the lawn until it is dry after application.

Care: Store in a cool, dry place away from children and pets. Ensure the packaging is sealed after use.
