How to mulch grass and leaves

Mulching your lawn with grass and leaves can save you time as well as money. Here are our best tips when mulching your lawn with grass cuttings and leaves.

Mulching is a great way to get rid of fallen leaves as well as leftovers from grass cutting. The use of a cutting deck for mulching means that when the grass and leaves have been cut the first time, they’re thrown back up into the cutting deck and then fall down onto the blades a second time. That way the waste is finely cut.

Effects of mulching

在草坪上覆盖草和树叶有许多好处,如可以节省时i间和金钱,并且改善草坪的质量和外观。 Here’s a list of the perks of mulching:

  1. Turning waste into nutrients, thus reducing the need for fertilisation
  2. Improved micro life
  3. Increased humus layer
  4. No need for removal or composting of waste, which is good since throwing away grass cuttings adds to the already overloaded landfill sites

When to mulch

Mulching should only be done when there is active micro life in the soil. That means that the temperature in the surface layer of your soil should be at least 6 degrees Celsius. If mulching is done regularly when the grass is not growing, for instance during the warm summer months or late in the autumn if you live where seasons change, there will be little or no decomposition. Consequently there will be a greater risk of thatch development.

Mulching grass cuttings

Grass remains contain 80 to 85% water, which makes it decompose quickly with low risk of causing thatch, unlike other dead plant remains. 如果每次只切掉草叶长度的三分之一,残留草的分解速度将会最快。 However, no more than half of the length of the blade should ever be cut, as this would increase the risk of dehydration due to loss of fluid in the plant.

Leaf mulching

在覆盖树叶时,如果树篱、花坛和道路中的落叶被吹到开阔的草地上,就可以使用装有碎草装置的骑行草坪机来切碎它们,从而节约成本和时间。


When to collect instead

Keep in mind that mulching cannot altogether replace the traditional collection of leaves. Therefore, it’s a good idea to collect the remaining leaves after the last mowing of the season, when the ground temperature is below 6 degrees Celsius and the grass has stopped growing. Otherwise the risk of problems like fungal attacks increases during the winter.

Leaf mulching in different parts of the world

Depending on climate there are different things to consider when mulching. In northern Europe, for example, it’s important to remember when mulching leaves that only a small proportion of the leaves fall before the first frost, while a large part of it fall soon after. 在秋季让草比正常情况多长高几厘米,这样您就可以在短时间内覆盖更多残留的树叶,因为覆盖残留物会掩在较高的草中。
