Mulching with grass clippings has started to become extremely popular in the past couple of years. The availability and the ease of use of grass clippings as mulch means that more and more people will start using their grass clippings instead of outright throwing them out. Mulching with grass clippings is excellent for vegetables, flowers, and even fruit trees, but a lot of people do make mistakes when it comes to mulching with grass clippings, especially if they use it around their trees.
Grass clippings around trees are an ideal way of providing valuable nutrients to the tress and also keep the nearby soil moist. On the other hand, if the grass clippings are in direct contact with the trees then they can do more harm than good. Make sure to place the grass clippings around your trees and not directly on the stem of the tree, just leave a couple of inches between the grass clippings and the trees.

Grass Clippings Around Trees Without Direct Contact
Probably one of the biggest mistakes that someone can make when it comes to grass clippings is to pile them on the base of the tree. While this might look practical, but it can actually damage the tree, given enough time. As grass clippings are excellent at retaining water, they will be an excellent environment for fungal growth. Some fungi are beneficial for the growth of the tree but others can be extremely harmful.
This is one of the main reasons why you should not pile the grass clippings around trees, as sooner or later the fungal growth will start damaging and even rotting the tree. Make sure when you are using the grass clippings around your trees to leave a couple of inches between the grass clippings and the trees, in such a way that they are not touching each other.

Using Too Much Grass Clippings Around Trees
In a lot of neighborhoods, people seem to simply pile the grass clippings around their trees, and after a while, it looks like the tree is growing out of a small hill. This is extremely harmful to any tree for two reasons, due to fungal growth and due to the anaerobic bacterias. Anaerobic bacterias do not need air to survive, and your main goal with mulching or composting is to have aerobic bacterias which need air, this way they will also aerate the mulch or compost.
If you are using too much grass clippings around your trees, then sooner or later the anaerobic bacterias will take over. The anaerobic bacterias do break down the grass clippings but they do it a lot slower than bacterias that do need oxygen. Go check the grass clippings around your trees, and if the bottom layer of grass clippings are compacted, gray, and look like a fuzzy carpet then you are using way too many grass clippings.
To fix this problem, you will have to remove the old grass clippings and add a thinner layer of fresh grass clippings.

Grass Clippings Around Trees Can Attract Pests
Grass clippings around trees can be an ideal home or hiding spot for a lot of different pests. The most common pests the grass clippings will attract are slugs and snails, although, for the most part, they are harmless to most trees, but if you have flowers or vegetables growing nearby then this could be problematic. Ants will oftentimes set up shop at the base of the tree especially if the grass clippings are touching the tree.
In the worst-case scenario, the grass around your tress will be an ideal home for mice and rats. If you start to notice an unusually high amount of pests in your area then make sure to check the grass clippings around your trees.

Grass Clippings Around Trees Will Leave A Bare Spot
I know that you already know this, I am not trying to insult your intelligence but a lot of people freak out when they use grass clippings around their trees and see that nothing grows in those spots, even after they have removed the grass clippings. This is perfectly normal, as the grass clippings will simply smother the weeds and other plants that might want to grow in those spots. Keep in mind that if you remove the grass clippings the bare spot will still be there for a good while.
Grass Clippings Around Trees For Fast Nutrients
There are a couple of extremely important nutrients which all trees need, nitrogen and phosphorus. The good news is that grass clippings tend to contain a lot of these nutrients and the even better news is that they will release these nutrients a lot faster than if you would be mulching with wood chips. Grass clippings fully decompose in a couple of weeks or months, depending on your climate, and the faster they decompose the faster the nutrients will be readily available for your trees.
On the other hand, if you are using wood chips as mulch, these also contain nitrogen and phosphorus, but these nutrients will be trapped inside them for years mostly because wood chips tend to decompose relatively slowly.
As you can see grass clippings are excellent around trees, just keep in mind that the grass clippings should never be in close contact with the tree. Make sure to check the grass clippings from time to time, especially if you have started noticing a lot more snails and slugs in your garden.
