What Are the Causes of Lawn Moss Growth?

When you notice signs of moss infestation, it is a signal of weakened grass. These are the main causes of lawn moss;

  1. Poor lawn care, including irregular mowing and little fertilizer addition that leaves the grass thin and weak.
  2. An excessive shade that leaves the ground moist most of the time
  3. Compacted soil that stores enough moisture for moss to thrive
  4. Unstable soil pH
  5. Poor soil drainage
  6. Low soil fertility
  7. Lawn thatch, made of dead grass, weeds, and roots, encourages a lot of moisture retention

Factors You Can Consider Before Buying the Best Moss Killer for Lawns

While moss can sometimes be good for the lawn, you will need to eradicate it if it becomes too much. However, as seen above, you will also need to address the root causes for its growth to prevent its regrowth after using a weed killer.

You could mow your lawn more often and get rid of excess lawn thatch. Also, if you notice you have compacted soil, you could look for ways to make it more breathable, thus less accommodating of moss in the future.

While you tackle the causes of moss growth, it will also be ideal to use the best moss killer to kill the moss growing on your lawn. Here are some vital factors that should influence your buying decision.

a) Type of lawn moss killer

There are two main types of moss killers for your lawn you can buy;

  1. Liquid/spray moss killers
  2. Granular moss killers

You can find liquid lawn moss killers that can also work for the roofs, walls, and other areas of your home with moss that needs eradicating. They are formulated without bleaches, thus will not bleach or stain woofs or walls, or other surfaces your need to clear moss from. Unfortunately, granular moss killers will stain your surfaces, thus only ideal for lawns.

A liquid lawn moss killer is a carefully formulated formula that is easy to apply and fast on eradicating moss. When buying, you will find it packaged in a spray bottle to attach to the hose for easy application.

If you decide to buy a liquid moss killer, you can also look for one with extra ingredients to boost the health of your grass. Often, these are vital nutrients such as iron to help treat the soil and strengthen the thinned grass for a fuller, green, and glossy lawn.

Granular moss killers are the most common options for lawns. They are packaged in bags and will require a spreader to spread all across the lawn.

Unlike the liquid lawn moss killers, granular killers are packaged for larger yards, often with a potential coverage of 5000 square feet. However, you will need to wet the lawn or garden after spreading so the granules can be better absorbed to control the moss.

b) Size of the lawn

You will need to estimate how much moss killer will be sufficient to cover your whole lawn, yard, or garden. When buying, you will learn from the packaging how much coverage you can expect. Most moss control products offer coverage from 500 sq. ft to 10000 sq. ft.

However, this coverage will depend on how much moss you want to kill without affecting grass, plants, and surfaces around the lawn. If your lawn is too infested, you may need to use more products or consult a professional landscaper to help you restore the health of your lawn.

c) Ease of Application

While it is easier to apply a moss killer during seasons like summer and autumn, you will also need to consider how much work you will have to do to kill moss quickly.

You can choose between liquid moss killers you can easily spray around your lawn or granular moss killers you can spread by hand or using a spreader if your lawn is large.

In addition, you can consider how the formula will kill moss quickly and if you will need to remove the moss from the soil. Some products will kill the moss, but you will also have to physically uproot it to make way for new grass growth.

Frequently Asked Questions (FAQs) About the best Moss Killer for Lawns

a) Why do I need a moss killer?

You will need a moss killer to get rid of moss infestation faster and encourage a healthier lawn. However, it is also important to find the underlying cause of the moss infestation and tackle it too to prevent the moss from regrowing in a few months.

b) When should I apply a moss killer?

It is best practice to apply a moss killer under wet conditions, and even so, right before you start to rake your lawn. Raking before applying a moss killer will likely spread the moss further, but raking after it is dead will completely eradicate it and promote better breathability for better grass growth.

c) Will healthy grass grow after killing moss?

A few factors will influence the regrowth of thick, glossy glass even after you've killed the moss.

Firstly, you will need to ensure you tackle the cause of moss infestation, in most cases, poor soil pH, poor soil fertility, soil compaction, or more. If your soil pH is too low, it is an acidic environment that will encourage moss regrowth.

Alternatively, if soil fertility is poor, you will also need to feed nutrients to the soil even as you use a moss killer. Healthy grass will only grow uniformly if the root cause of moss is addressed.

d) Do I need to rake the dead moss?

Yes, it is very important not to leave dead moss on the yard as this will encourage excess lawn thatching, which will inevitably encourage more moss regrowth.

e) Can I put grass seeds after moss killing?

You can plant new grass after the moss is killed, but this will depend on how much damage you see on the lawn. If there are big patches without grass, you can sprinkle a few seeds after treating the soil to encourage uniformity.

It is important to sprinkle the seeds carefully so they can sprout uniformly with existing grass and, in the long term, not require too much gardening to maintain a level surface.

Alternatively, you might not need to put seeds on the ground if the patches are very small, as grass can spread with good health.
