Preventive Tips Keep Moss From Growing/recurring

How to kill moss in a lawn | FAST and EASY

Although moss is harmless, its presence on lawns signifies unhealthy conditions that kill the grass. These poor conditions are overly shaded areas, poor drainage, compact soil, acidic soil, and close mowing.

Moss will regrow if you kill it and retain the conditions that favor its growth. You will need preventative measures that keep your lawn healthy to keep moss at bay completely.

Using Ferrous Sulphate As A Moss Killer

Ferrous sulphate is often seen advertised as a solution to lawn moss. Most chemical moss killers contain ferrous sulphate, and when contained in a proprietary moss killer and correctly applied, it is effective. However, it should not be used on its own as a moss killer because is likely to do more harm than good by killing off grass as well as moss.

Use A Natural Moss Killer

There are a number of natural moss killing methods the two best ones use either bicarbonate of soda or dish soap. These homemade techniques can be surprisingly effective at getting rid of moss, especially if your grass is otherwise quite healthy.

  • If using baking soda, add three tablespoons to a litre of water. Mix the solution together, dissolving the baking soda, and add it to a spray bottle.
  • If using dish soap, add 25mL to a litre of water, mix the dish soap into the liquid, and add it to a spray bottle.

Wait until the grass is completely dry, and you have no rain forecast for the next 24-48 hours. Then, no matter which method you have chosen, spray the liquid liberally over the moss on your lawn.

Wait around two weeks for the moss to die completely. If the moss still looks green after a few days, consider applying the solution again, with up to double the amount of baking soda or dish soap as before.

Once the moss has turned brown and died, its important to rake it away, and get rid of the dead moss. Then, youll need to use some of the methods weve discussed below to prevent the moss from returning to your lawn.

Its important not only to choose the best solution to killing the moss that has taken root in your garden, but also to understand what times of the day and year are best to apply the moss killer.

Moss is best dealt with during the early morning hours when the lawn is still damp from overnight dew. This allows the product to seep into the root systems, as well as covering the surface of the moss.

You should also check and make sure that no storms are forecasted for about a day after you plan to apply moss killer. Any heavy rainfall will simply wash away the product and youll have to start all over again.

In general, gardeners should aim to kill moss in their lawns during the late spring or early fall, when new growth has begun and before cool weather sets in.

Additionally, you should not seed the lawn before you set out to kill moss, as most moss remedies will harm newly germinated turfgrass as well.

Heaped Teaspoons Per Litre

I worked out the weight of a heaped teaspoon and it’s about 7 grams

So make up your iron sulphate solution to the following strength

  • 21 grams per litre
  • 2.8 ounces per US gallon
  • 3.4 ounces per UK gallon.

You can double up on the concentration to ensure more thorough results, but I have found this to be unnecessary. It also tends to blacken the grass as well as the moss . It also tends to stain concrete and gravel driveways.

Instead of using teaspoons which can be tedious, you can use an old weighing scales for weighing out the iron sulphate. Alternatively use a disposable cup or other container and add the required number of spoons into this for the capacity of your sprayer, e.g 5 litres. Mark the inside or outside of the container. Then in future you can just measure out by volume rather than by weight or counting spoons.

So to summarize:

    Try A Natural Moss Killing Solution

    If the idea of introducing herbicides to your lawn does not seem attractive, there could be a relatively safer alternative. We suggest you mix the following ingredients in a spray bottle to create a natural moss killing agent to use now and in the future, if the moss reappears:

    • 1 tsp of baking soda or 1 tsp of mild dishwashing detergent
    • 1 l of lukewarm water

    These are the ingredients to tackle relatively small moss-covered areas. You can double or even triple the amounts if the invasive plant has spread throughout your entire lawn.

    Its best to apply the solution in dry and sunny weather. Otherwise, the rain may wash away the solution before it has time to kill the moss. Aim to spray only the invasive plant.

    The minimum time this homemade moss killer requires is 24 hours, but the most telling sign of success is the change in colour of the plant from green to yellow or brown. When you are sure the moss is dead, pull it out from the root, place it in a bag and throw it out a solid distance away from your lawn.

    Ways To Kill Moss On Your Lawn

    Traditional ways of eliminating moss include spreading iron sulfate moss killer. You can also get rid of moss in your lawn by making it less acidic by adding lime to the soil. Or, you can use good old sweat equity and rake out the living moss from your lawn. But the simplest, safest method is to use dish soap. It’s easy to learn how to kill moss with this recipe that costs pennies to whip up. Just follow these three steps.

  • For small patches, mix in a garden hand sprayer 2 ounces of dish soap and 1 gallon of water. Use gentle liquid dish soap, such as blue Dawn, which you’ll find in most grocery stores. For larger areas, use 4 ounces of dish soap in 2 gallons of water for every 1,000 square feet of lawn.

  • Spray the mixture on the patches of moss. Holding the spray nozzle a couple of inches from the target area, drench the moss with the solution. Make sure not to spray the grass, as the solution can also kill healthy grass.

  • The patches of moss will turn orange or brown in 24 hours and eventually dry up. Dig up the dead moss. The dish detergent does not necessarily kill moss at the roots, so remove as much of the moss as possible. The surrounding grass will begin to grow over the patches.

  • After raking up the dead moss, take it to an isolated area. Don’t compost it or the moss spores could spread back into your lawn. Wait to re-seed bare areas left by the dead moss, as the liquid soap can impede germination. Top the new grass seed with new, loose soil that’s free of moss spores.

  • What Causes Moss In Lawns

    Moss thrives in damp and wet, cool conditions.

    • Bad drainage. If the underlying soil is compacted and clayey, and doesn’t drain well, it can remain excessively wet after rainfall
    • Topology of the Lawn. If your lawn isn’t flat and at the bottom of a slope, or has slightly hollow shaped sections like a saucer , water will tend to collect. This in addition to bad drainage can make the lawn excessively wet
    • Lack of Nourishment. If you don’t feed the lawn, moss can out compete grass
    • Shade. Sun tends to dry out the lawn and reduce the effects of water logging. However in the shade of buildings or under trees, moss can thrive in low light conditions while grass struggles. You may have noticed this in a forest where conditions are damp and moss grows on trees but very little grass is to be seen
    • Climate. There’s not much you can do about this. If you live in a country which has a mild climate and lots of rain, moss can be a serious problem although growth will stall somewhat during long dry spells in the summer

    Rake it Out

    Because moss has shallow roots, you may be able to get rid of it simply by raking it out. Vigourously rake your grass to ensure the moss comes out. A bit of grass might also come out, but grass has longer roots and will be able to survive a thorough raking.

  • Step Things up with Baking Soda

    Try organic options first, with two main ones available:

  • Mix two gallons of room-temperature water with a box of baking soda. Apply it evenly to your lawn where moss is growing, soaking the grass 1/2 to 1 inch below the surface.
  • Use gentle dish detergent and mix 1 to 2 tablespoons of it with one gallon of water. Use a watering can to apply it evenly and thoroughly to your lawn.
  • 3

    Test the pH of Your Soil

    Use a kit to determine the pH of your soil. Sometimes if your soil is too acidic, you may need a more alkaline soil to effectively compete with moss. Garden lime is a good tool to use in this case, as are compost and fertilizer.

  • 5

    Reduce Excessive Shade

    Moss likes dark, cool conditions, so reducing the amount of shade covering it can help eliminate moss. Prune branches or shrubs that may be casting nearby shadows or plant shade-resistant grass to help crowd it out.

    How to Remove Moss from your Lawn – Great Lawns Made Simple

    You can treat moss using a chemical called iron sulphate . It can be spread as a dry powder, however personally I find it’s much more convenient to spray it or use a watering can, and this gives better coverage than spreading dry powder by hand which can produce patchy results. When you spray iron sulphate, moss turns black within about 20 minutes, so it’s easy to see whether you missed any spots.

    Iron sulphate will stain clothes, hands and everything else brown, and the dry dusty powder can irritate eyes. When sprayed, It will stain concrete and tarmac to some extent so you might consider alternative chemicals as a treatment on these materials. Vinegar, bleach or salty water will burn moss and can produce good results. Boiling water also scalds moss and weeds. If you spray iron sulphate solution, the resultant stains are not as bad as those which result from scattering the dry powder.

    Once you treat your lawn with iron sulphate, the moss will turn black and also the grass to some extent. This is why it’s best to spray in the spring. Firstly you will have dealt with all the moss growth which accumulated over the winter, and secondly any staining of the grass will be eradicated once you start mowing your lawn again.
