Wondering what to do with the cut grass on your allotment or in the garden? One possibility is: compost from grass. How to make it, for what and when to apply? What does compost from grass contain? How to speed up the composting of grass and prevent it from rotting in the composter? – we suggest in the next part of the Composting Guide.

Compost from grass – nitrogen content and pH.

Compost from grass contains a lot of nitrogen in ammonium form, which acts relatively quickly and has a beneficial effect on plants, especially during the growth phase. That's why it's worth sprinkling it on the plants from time to time, especially since this fertilizer This fertilizer can be used without the risk of over-fertilization of the soil (some nitrogen will be leached out of the soil with rainfall anyway).

As for the pH of this fertilizer, it is known that the pH content of grass compost will never be the same, but as a general rule, the fertilizer from grass has a pH of slightly acidic (the pH of grass compost stays within 6.7 pH).

What to use compost from grass for?

Cut grass as fertilizer can be used to fertilize the lawn or plants, Which do not require very acidic soil. Compost from grass can be used, among other things. Under thuyas and other conifers. If you feed such compost to your plants, it is a good idea to mix the fertilizer into the soil. You can do this by hand or with a rake.

Is it possible to compost grass alone?

We advise against composting grass alone, because such fertilizer is sticky and to say the least – has an offensive smell. much to say – it has an offensive smell. Fertilizing with such compost will not only be unpleasant, but will also reduce the supply of oxygen in the soil.

However, this is not the only reason for mixing grass with other scraps. residues. Mowed grass can clump together in the pile, which impedes air circulation air – the compost begins to rot and mold, which is harmful to plants and can make them sick.

CAUTION: do not compost grass that has been sprayed with herbicides (this agent is present on plants for up to 9 months).

Composting grass – where to start?

Freshly cut grass contains a lot of water, so it is worth drying it before composting – to do this, just spread it on the ground. After about 3 days, the grass will be ready, and thanks to the evaporation of water, it will also reduce its volume. It is also a good idea to clean the cut grass from tough stems and inflorescences, so that the composted layers will spread evenly.

Compost from grass – how to layer?

To ensure uniform decomposition of the compost, layers of composted matter should be Pile alternately – once dry, once wet. This will provide access to air and prevent rotting. Thin layers of grass should be overlaid with dry and loose material. material, such as shredded branches (larger parts of them can take longer to decompose), shoots, soil. The wet layer here will be grass, which you You can also mix with other plant debris, such as weeds (make sure make sure there are no seeds in them). On the other hand, on the bottom of the composter make a slightly a thicker layer consisting of shredded branches and such as straw.

Also, don't forget to stir the compost once a month. By doing so you will not only provide the oxygen important in the composting process, but also you will mix the undecomposed scraps with the processed ones, and the finished compost will fall to the to the bottom of the composter.

If you are composting grass in late autumn or winter, be sure to cover the compost with an with an extra layer on top, which will keep the heat in the composter (temperature is an important factor in faster composting).

How to speed up composting grass?

Decomposition of such mixed compost can take from 9 to about 12 months – depending on weather conditions (the warmer it is, the faster the decomposition process occurs faster) and other factors, such as moisture and access to oxygen. What else affects the decomposition time of the residue is the bacterial flora, which you you can introduce into your compost by using the right biopreparation -recommend bacteria for compost Biocomposter.

Using Biokomposter compost bacteria, you will shorten the decomposition process up to 2 months, and in addition, you will eliminate parasite eggs from the fertilizer and increase the fertility of the fertilizer (the metabolism of bacteria makes the decomposition of organic matter more efficient). In addition, due to faster decomposition, the composted grass will not emit such a strong odor.
