Flowers are beautiful, and they brighten up any room. But what do you do with them when they start to wilt? Can you compost them?

The answer is yes! Most flowers are actually quite good for composting. They add valuable nutrients to the compost pile, and help to balance out the carbon-to-nitrogen ratio.

However, there are a few types of flowers that should not be composted. These include flowers that have been treated with pesticides or other chemicals, as well as flowers that have a lot of resin (like pine cones). It’s always best to check with your local composting authority to see what they recommend.

In general, though, flowers make great additions to the compost pile!

What is composting?

Composting is the process of breaking down organic matter, such as food and plant waste, into a nutrient-rich soil amendment. This can be done through simple backyard composting or with the help of worms, also known as vermicomposting. Adding compost to your garden can improve plant growth, reduce the need for chemical fertilizers, and decrease water usage.

Organic matter that can be composted includes fruits and vegetables, eggshells, coffee grounds, tea bags, yard waste such as leaves and grass clippings, and even paper products that are free of chemicals.

What can be composted?

Fruits and vegetables, coffee grounds and filters, eggshells, and nut shells are all compostable items that will break down quickly.

Grass clippings, leaves, twigs, and branches are also compostable items, but they take longer to break down.

Paper products like newspaper, paper towels, cardboard, and gift wrapping can be composted, but it’s best to shred or tear them into small pieces first.

Yard waste like grass clippings and leaves make up about 28 percent of the solid waste in landfills, so composting them is a great way to reduce your environmental impact.

Flowers are also compostable, but it depends on the type of flower. Flowers that have been treated with pesticides or other chemicals should not be composted.

Flowers as compost

Flowers are organic matter and can be composted using the same methods as other kitchen and garden waste. The main thing to remember is that some flowers, especially those with a lot of pollen or nectar, may attract unwanted insects to your compost pile. You can avoid this by composting delicate flowers in a closed container or by adding extra leaves, grass clippings, or straw to the pile to absorb any excess moisture.

In general, it is best to compost flowers that have not been treated with pesticides or other chemicals. If you are unsure whether your flowers are safe to compost, it is best to err on the side of caution and avoid adding them to the pile.

Advantages of composting flowers

In addition to reducing waste sent to landfills, composting flowers has a number of other benefits. Flowers can help speed up the decomposition process by providing extra nitrogen. This is especially helpful in the fall when leaves are high in carbon and can cause the compost pile to slow down. Flower petals also add color, texture, and nutrients to the finished compost.

There are a few things to keep in mind when composting flowers. First, it’s important to remove all traces of pesticide before adding them to the pile. Second, avoid adding diseased plants or invasive species that could spread in the compost. Finally, while most flowers are safe to compost, some do not break down well and can actually hinder the decomposition process. These include tulip bulbs, coconuts, and woody stems.

Disadvantages of composting flowers

While many types of flowers are technically compostable, the process of breaking them down can take significantly longer than other organic materials. Additionally, certain flowers may contain harmful toxins or chemicals that can
contaminate your compost pile and potentially harm plants that later receive the compost.

Some common flowers that should not be composted include:
-Gerbera daisies

If you’re unsure whether a particular type of flower is safe to compost, it’s best to err on the side of caution and avoid adding it to your pile.


After doing some research, we have found that not all flowers are compostable. In fact, many popular flowers such as roses and lilies are not compostable. This is because they are often treated with chemicals that make them last longer.

If you’re looking for flowers that are compostable, we recommend sticking to simple bouquets of daisies, sunflowers, or other wildflowers. These flowers have not been treated with chemicals and will break down much more easily in your compost pile.
