Compost is a very good idea. It helps to get rid of excess debris and grass, and in return provides excellent fertilizer for the plants grown on the site. However, not every garbage is suitable for composting, some substances do not decompose in the soil, while others can even harm plantings. What absolutely shouldn't be put in compost?


When choosing plants for the compost heap, it is very important to carefully sort through them and throw out the weeds so that the compost does not spread them throughout the area. Weeds are very tenacious plants, and man himself made them so, fighting them in every possible way. You need to carefully examine the grass for the presence of weeds and their seeds, and only then can the grass be added to the compost.

Meat and dairy products

It is better to dispose of such products in any way, but not in compost. The fact is that rats, mice and insects can come running to their smell, and not a single summer resident will be happy with such neighbors. Mice, for example, can begin to stir up not only compost, but also crops, and then climb into the house and gnaw everything there.

Fatty and fried foods

Not only are they a treat for rats and mice, but they hardly decompose in the soil.

Plants treated with pesticides and diseased plants

In addition to the presence of weeds, plants need to be checked for disease. It is better to destroy a diseased plant, because the disease will not go anywhere in the compost, and such compost will become dangerous for healthy plants. Also, pesticides are not going anywhere.

Sawdust of unknown origin

It is important to understand that sawdust treated with various varnishes and other substances is categorically unsuitable for composting, they can contaminate the soil and damage the crop. Therefore, you should always monitor the origin of the sawdust before using it in the garden.


If plain paper is an excellent component for a compost heap, then various newspapers and magazines are best sent for recycling as waste paper. The fact is that the coating used for this kind of publications can be harmful to the soil and plants, so it is better to use plain paper.

Pet feces

It is better not to put this material in compost and generally keep pets away from the beds. Feces can contain parasites that are hazardous to health. It is better to add combed wool there, after making sure that the animal has not been treated with chemistry from fleas and ticks.
