Moss Growing On Garden Soil Needs Lime?
Lots of people want to know how to get rid of moss in the law, but a better question to ask is, "why does moss grow in lawns?"The most common response to this question is that the lawn receives too much shade and that the soil is acidic. The common advice is that grass will grow better if you limb up the trees and add lime to the soil to make it less acidic. Or you can spread a moss killer for lawns.
What about moss that is growing in a sunny area? What about moss growing in soil that is alkaline? There is much more to the moss story and the only way to really get rid of moss in a lawn is to understand why it is there in the first place.

Moss in Lawn is Not a Sign of Acidic Soil.
Moss does prefer to grow in acidic soil, but it will grow just fine in alkaline soil. Part of my lawn is shady, wet and has a pH of 7.4. Moss grows much better than grass in that area. The picture above is a 4 foot high limestone bolder that is covered in moss – it is certainly not acidic.
The common advice of liming the soil will make it less acidic if done properly, but it will not get rid of moss. Liming can actually make the situation worse. Unless you know for sure that your soil is too acidic for growing grass, do not add lime.
Moss is one of those plants that can grow in spots that are inhospitable to other plants, including:
- Too much shade
- Too wet
- Compacted soil (ie lack of air in the soil)
- Low fertility
When you have moss in your lawn, the moss is not the problem. The real problem is that you are trying to grow grass in a spot where it will not grow well. If the grass is not growing well, moss takes advantage of the situation and moves in. Moss will not invade a healthy growing lawn.
Moss Killer
You can spread lawn moss killer, which usually contains some form of iron sulphate (ferrous sulphate or ferrous ammonium sulphate). This will kill moss since moss does not grow well with high levels of iron in the soil. You can also rake out the moss and physically remove it from the lawn.
The problem with either if these options is that they do not work long term. Unless you fix the real problem ie grass not growing well, the moss will soon return to the lawn. There are really only two options. Leave things alone and embrace the moss as a natural ground cover, or fix the problem so that the grass grows better.
How to Get Rid of Moss in a Lawn?
In order to fix the problem, you need to first identify the problem, but any or all of the following will improve the growing conditions for the lawn.
– Reseed with shade tolerant varieties of grass – if the area is shady
– Aerate the soil – reduces compaction
– Add organic matter to the soil
– Fertilize more if there is a nitrogen deficiency
– Reduce the amount of shade ie thin or limb up the trees
– Water less if it is a wet area, water more if it is a dry area
– Cut grass higher to encourage stronger grass roots
Moss Grows in Full Sun
It is a myth that moss grows only in shady wet areas. There are many kinds of moss and some of them like to grow in dry sunny areas, even desserts. Sun loving moss will invade a sunny lawn.
Moss is Not Always Moss
There are some garden plants that look like moss and some that even have 'moss' in their name. The following are not true mosses
- Spanish Moss (is an epiphyte)
- Caribou Moss (is a lichen)
- Iris Moss (is a vascular plant)
- Scotch Moss (is a vascular plant)
