This waste can slow down or even stop the decomposition process

Composting is an easy way to turn kitchen and garden waste into something useful for the garden. But not everything suits her equally. Some food waste creates an odor that can attract pests, and some yard waste can slow or stop the decomposition process, which can be very uncomfortable. You don’t want to add anything that could harm you or your plants when using ready-made compost in your garden, do you? In this article, you will discover what not to compost and what household waste you may not know about composting.

What is not allowed on the compost – meat and fish residues

The stench of stale seafood or the stench of rotting meat is sure to make you feel uncomfortable. But those foul odors are also magnets for raccoons, rats, flies, and many other wildlife, including some nearby pets. So never put meat, fish, or bones in a compost heap. Even if you have a closed compost bin, the smell can attract pests to picnic there.

Dairy products, fats and oils should not be thrown on the compost

Dairy products, fats and oils in a compost bin attract rats and flies

Dairy products such as cheese, butter, milk, sour cream and yogurt, as well as fats and oils, should be avoided for the same reason: they attract unwanted visitors. You should also avoid processed foods that are high in dairy or fat.

Chemically treated plants and wood

What not to compost - some waste can stop the decomposition process

Never add plants to your compost that have been treated with insecticides, fungicides, or herbicides. Residues from chemicals used in the garden to kill insects and control plant diseases can inadvertently kill beneficial organisms in compost. Herbicide residues can affect plants once compost is added. The same goes for pressure-treated, painted, stained or varnished wood.

Plants that are diseased or attacked by pests

Killing insects and pathogens such as fungi and bacteria requires a hot compost pile (up to a temperature of 140-140°F (60-63°C) and maintained for at least several days). Unfortunately, most home compost bins and piles never reach temperatures high enough for pests and diseases to remain inside.

What should not be on the compost – weeds grown hectarest: Same for weeds that have developed seeds that can generally survive as long as compost temperatures don’t reach 140°F (63°C). There is no point in sowing weeds next year while applying the finished compost.

Dog and cat droppings don’t belong in the compost heap

Dog and cat waste can become hazardous waste

Dog and cat feces can turn the final product into hazardous waste because cats and dogs can carry bacteria and parasites that cause disease to humans. Roundworms are the most common problem with dog poop. Cat feces and litter are of even greater concern because they can carry the causative agent of toxoplasmosis, a disease particularly dangerous for pregnant women because it can seriously harm an unborn baby.

What should not be in the compost – black walnut tree debris

Black walnut contains juglone, which inhibits the growth of many plants

Most untreated garden and yard waste is a good addition to your compost pile, but there are exceptions. The leaves, twigs, and especially the roots of the black walnut tree contain a natural substance called juglone, which hinders the growth of many plants and can kill them. Some plants appear to be more delicate, including edible plants such as tomatoes, peppers, and potatoes, and ornamentals such as azaleas, viburnum, and hydrangeas. Research has found that over time and with sufficient heat, juglone will degrade to the point where it loses its toxicity, but black walnut cuttings are best left first.

Coal ash should be avoided

Coal ash does not belong to the compost heap

Ash on Compost – Although you can add ash from a wood-burning stove or fireplace (in limited quantities), coal ash should not be added. First, these materials are high in sulfur, which can make your finished fertilizer too acidic for most plants. Second, charcoal briquettes often contain chemicals that can harm plants.
