Westland Aftercut All In One Autumn Lawn Feed and Moss Killer - 160m2

The best time to apply is during autumn, ideally from September to November, when the grass is still growing and moss is prevalent.

No, this product is not suitable for newly sown or laid lawns. It requires the lawn to be established and at least 12 months old.

You should see the moss begin to turn black and die within 7-14 days after application.

Once the moss has turned black and died, it should be raked out of the lawn. You can then use a lawn repair product for any thin or bare patches.

The NPK ratio is 4-5-15, which is specifically formulated for autumn lawn care with high potash content.

The product contains a combination of high potash lawn fertiliser and ferrous sulphate to kill moss and feed the lawn.

Ensure the product was applied evenly and at the correct rate. Environmental conditions (e.g., very dry or cold weather) can sometimes slow the process. Reapplication is not recommended without consulting the product label for specific guidance.

This may be due to over-application or application during very hot, dry weather. Ensure an even spread and avoid applying when the temperature is above 21°C. Water the lawn lightly if scorching is suspected.

Consider using a lawn spreader for more consistent coverage. If applying by hand, divide the lawn into sections and apply a pre-measured amount to each section to ensure an even distribution.
