Putting lemon peel around the compost heap can serve multiple purposes:
Ant Repellent:
Lemon peels contain compounds that can repel ants. Placing them around the compost heap can deter ants from invading the area without drastically altering the pH of the soil, as would happen if you applied lemon juice directly.
Odor Neutralizer:
The fresh smell of lemon can help neutralize unpleasant odors emanating from decomposing organic matter in the compost heap. It adds a natural, citrusy fragrance to the area.
Fly Deterrent:
Lemon peels can also help keep flies away from the compost heap, especially when placed near windows or other entry points. The strong scent of citrus acts as a deterrent for flies.
Rodent Repellent:
Mice and rats dislike strong odors, including those from citrus fruits like lemon. Placing lemon peels around the compost heap may help deter these pests from frequenting the area.
Prevent Cockchafer Development:
Some gardeners believe that the strong smell of citrus fruits, including lemon, can deter cockchafers, thus preventing the development of white grubs in the compost pile.
As for whether lemons can be added to the compost itself:
- Yes, lemons can go in the compost: Despite their high acidity, lemons and other citrus fruits are organic matter that can be composted. They are considered green materials and can be added to the compost pile. Cutting the peels into smaller pieces can help speed up the decomposition process.
- Moldy lemons: Moldy lemons can still be added to the compost. Mold is a natural part of the decomposition process and helps break down organic matter. However, if you see black, blue, or green mold, it’s best to bury the contents deep in the garden rather than adding them to certain types of composting systems like Bokashi.
- Cutting citrus fruits: You can choose to put citrus fruits in the compost heap whole or cut into pieces. Whole fruits may decompose more slowly, while cutting them into pieces can help accelerate the process. However, avoid cutting rotten fruit to minimize the risk of inhaling mold spores.
