When & Where to use moss killer

For best results, you should use this product to remove moss and improve the colour of the grass blades before you rake or scarify the lawn

Apply during Spring, Summer or Autumn when the weather is not too hot and not too cold. Don’t apply if frost is forecast.

It’s perfectly fine to apply moss killer at any time of year but you want to make sure the grass is growing well when you scarify.

The best time to apply this product early in the growing season – March or April – as part of a year round lawn care programme.

When to expect seeing results from ferrous sulphate moss killer

The fast acting formula will blacken moss within 2 days. After which, you should rake or scarify the dead moss from the lawn.

The grass will turn greener over the following 2 weeks

How to apply moss killer

The simplest method is by mixing the granules with water and sprinkling the mixture over a marked out area on the lawn. There are 2 popular methods of applying iron sulphate to lawns. One is with a watering can and the other with a knapsack sprayer.

How much moss killer to use

How much iron sulphate to use with a watering can

For moss control hen using a watering can, you will need 4 grams per litre of water and 1 litre of water will cover 1 m2.

For example, if you have a 10 litre watering can, that’s 40g mixed with 10 litres of water, sprinkled over 10m2.

How much iron sulphate to use with a knapsack sprayer

For moss control when using a knapsack sprayer, you will need to mix 4 grams of iron sulphate with 200ml of water to cover 1m2.

For example if you have a 16 litre knapsack sprayer, that’s 320g mixed with 16 litres of water to cover 80m2.

Knapsack sprayers have finer nozzles so they can apply the right amount of product without needing as much water

Is Iron Sulphate safe for pets and children

As this is a non-toxic product, it is safe to use where pets and children play. However, iron sulphate is known to stain surfaces. So, it’s recommended to keep pets off treated areas until it has been properly absorbed by the lawn – usually a couple of days or after a heavy downpour. That way it removes any possibility of their fur being stained by the product.

  2. Naomi

  3. DT

    Decided to go for the premium stuff to kill the moss in my lawns. I put it on near the end of January and did not know how much it would work. Mixed in a watering can and used it to cover the area. Due to it being a bit cold did not expect much. Within 7 hours the moss was black and started to shrink. The grass also took on a greener look. I can highly recommend it’s purchase. The product is good value for money and very pleased with the immediate results. Very happy so far.
