What not to compost: Common mistakes to avoid
Composting is a method to transform waste into valuable fertilizer. However, not all scraps are suitable for this process. Here's what should not be thrown into the composter.
Composting is not just a way to dispose of organic waste but also a means to obtain high-quality fertilizer for garden plants. Unfortunately, many people make mistakes in composting by placing unsuitable waste in the container. We explain which scraps are okay to discard and which should be kept out of the composter.
What not to throw into the compost?
We often aren't aware that scraps of animal origin shouldn't be placed in the composter. Meat, bones, or even dairy products should be avoided. Why? These items attract pests such as rats or insects and can emit unpleasant odours.
A composter with animal scraps not only attracts pests but also becomes a source of various pathogens. Bacteria and viruses can proliferate in these conditions, making the compost dangerous for the plants it was meant to enhance. It's crucial to remember that meat and fish scraps should go in the trash, not the composter.
Now let's head to the kitchen, which is often a source of scraps that seem suitable for composting. However, not every kitchen waste is appropriate for composting. Many fruits and vegetables can be included, but special care should be taken with citrus fruits. Peels from lemons, oranges, or grapefruits can acidify the compost, making it unsuitable for fertilizing plants.
Citrus fruits are often covered with pesticides and preservatives that can disrupt the development of microorganisms essential for the proper decomposition of organic scraps.
Do not throw cooked dishes, especially those containing fats and oils, into the composter, as they can negatively affect the processes occurring in the compost. Instead of improving soil quality, such waste can retain moisture and block oxygen access, leading to rotting and unpleasant odours.
We should also not overlook waste from our garden. Although many plants compost well, those that are diseased or pest-infested can become a serious problem. Mould spores and pest eggs thrive in a moist composter, spreading to the rest of the waste.
Some weeds, especially those that have already produced seeds, should be kept away from the compost. There's a risk that such a mixture will create ideal conditions for their proliferation, eventually ending up in our flower beds.
Avoid throwing large branches into the compost, as they decompose slowly. If you wish to include branches, cut them into smaller pieces. Pet waste should also be avoided in the composter, as it may contain pathogens and parasites hazardous to health. Additionally, avoid placing coloured newspapers, foil, synthetic materials, or coal ash into the compost.
What to remember when composting waste?
Composting waste is an excellent way to obtain valuable fertilizer for garden plants. However, to create good compost, it is essential to follow guidelines regarding the waste that can be placed in the compost.
Before discarding waste, ensure a thorough selection. It's also vital to balance green and brown materials, which support the decomposition process and facilitate air circulation. Regularly turning the compost and adding fresh organic ingredients helps produce excellent fertilizer.
