The answer is not really. Coffee is bad for plants for the same reason most people love drinking it. Coffee is allelopathic, meaning it reduces the growth of other plants that compete with it for nutrition. Coffee is not the only plant that has a negative effect on other plants, but it is the most common.

In fact, it’s so common that it has its own name – coffee rust. This rust is caused by a fungus that lives on the leaves of coffee plants. The fungus eats away at the plant’s leaves, causing them to turn brown and eventually fall off.

Once the rust has taken hold, the coffee plant can no longer produce its normal amount of caffeine, which means it can’t compete in the pollination process. As a result, many plants will die off, and others will be able to produce enough caffeine to keep the rest of their plant alive.
