Why Coffee Grounds

Coffee grounds are toxic to plants. This may not be a secret to many coffee drinkers, but it’s an interesting tidbit of information for those who care about our plants. Coffee grounds can be quite destructive to plants if left on the soil’s surface. They can form a thick layer of organic matter that will suffocate the plant’s roots. Additionally, coffee grounds contain high acidity levels, which can damage plant cells. If you’re growing plants in containers, rinse the grounds before placing them in their new home.

List of Plants that do not like Coffee Grounds

Cacti and Succulents

Cacti and Succulents


Cacti and succulents have very sensitive root systems and thrive best in sandy soil with little or no organic material added to them. The high nitrogen concentration in the coffee grounds will cause these plants’ roots to rot and die off quickly, leading to other problems such as root rot or stunted growth.




Tomatoes need a lot of nitrogen, and use it quickly, so adding coffee grounds will kill them if you use too much. It is better to add compost or aged manure instead of coffee grounds.

Fruit Trees

Fruit Trees


They need a lot of potassium, phosphorus, and calcium, but coffee grounds do not provide enough nutrients for fruit trees. It would be best to use compost or aged manure instead of coffee grounds when planting fruit trees.

Aloe Vera

Pulpy plant and the Middle East. It’s been used as a medicine and an aid to skin care for centuries. Despite its popularity, aloe vera doesn’t like coffee grounds very much. When they’re brewed with coffee, the acidity of the grounds can cause damage to the plant’s cells.




Grapes are a type of fruit that typically does not like coffee grounds. The acid in the coffee grounds can damage the skin and pulp. The coffee grounds can also contain caffeine, making it difficult for the grapes to absorb nutrients.




Coffee grounds can be a nuisance for plants as they can harm them by leaving behind a bitter residue. This is why many plants do not like coffee grounds, including blueberries.

Peace Lily

The Peace Lily likes moist soils with good drainage, but coffee grounds can make the soil too wet and cause rot. Avoid watering your peace lily on coffee grounds, as this will only worsen the situation.


Geraniums prefer slightly alkaline soil, and coffee grounds can increase the acidity, potentially affecting their growth.


Asparagus plants prefer neutral to slightly alkaline soil. The acidity of coffee grounds may not be suitable for them.

Whiteflies-Prone Plants

Coffee grounds can attract whiteflies, so plants susceptible to whitefly infestations, such as tomatoes, cucumbers, and peppers, may be negatively affected.

Pros and Cons Of Using Coffee Grounds In Plants

Pros Cons
Coffee grounds are a rich source of organic matter, adding nutrients to the soil. Coffee grounds are acidic and can potentially alter the pH of the soil.
They improve soil structure and drainage, especially in compacted or heavy soils. Excessive use of coffee grounds can lead to a buildup of caffeine, which may negatively affect plant growth.
Coffee grounds can attract earthworms, which help aerate the soil and enhance nutrient availability. Coffee grounds can retain moisture, potentially causing root rot if overused or in poorly draining soil.
They can act as a natural mulch, suppressing weed growth and conserving soil moisture. Coffee grounds should be properly composted or mixed with other organic materials to avoid compacting the soil.
Some plants, like roses and acid-loving plants, benefit from the acidity provided by coffee grounds. Improper application or excessive amounts of coffee grounds can create a crusty layer on the soil surface, inhibiting water infiltration.
