Which Plants Do Not Like Coffee Grounds?

If you’re looking for a cheap, natural fertilizer that is highly nutritious for plants, coffee grounds are a great choice. However, if you’re growing acid-sensitive plants, they might not tolerate coffee grounds well. Also, coffee grounds contain a lot of nitrogen, which will stunt the growth of certain types of plants. For these reasons, they’re best used in nutrient-poor soil and for plants that tolerate a slightly acidic environment.

Cyclamen coum

Cyclamen coum likes to grow in soil that is both acidic and alkaline, but it prefers loose soil with good drainage. This plant grows best in pots or raised beds. It will tolerate light shade and is hardy in USDA zones 2-7. The plant will grow best in well-drained clay or chalk. Adding coffee grounds to the soil will help provide the plant with rich nutrients.

Cyclamen coum does not like to be overwatered. It likes a slightly acidic soil and will benefit from an acid fertilizer once a year. Be sure not to overfeed the plant, however, as too much fertilizer will result in lush foliage but no blooms. Cyclamen coum usually blooms in the winter, and goes dormant in the spring. It is native to the Mediterranean, as well as Turkey and some parts of Europe.

Cyclamen coum is a semi-shrub that grows along the Black Sea coast and in southern Israel. Its leaves are round and variegated with silver. The flowers are magenta with a darker base and are produced in abundance during the winter and early spring.

Cyclamen coum can be grown in pots and containers. While some species benefit from subtle changes in cultivation, they generally don’t need special care. Plants can be transplanted in September and will flower again in the new year.


Daffodils are tolerant of coffee grounds, but do not like wet roots. A solution to this problem is to add dried wood ash or coffee grounds to the soil around the bulbs. This mixture will aid the roots in absorbing moisture. Also, daffodils prefer a well-drained soil. Watering is necessary every week to maintain optimum growth.

If you are planning to grow daffodils in your garden, it is crucial to keep in mind that they are only seasonable and rarely perennial. They bloom during the spring season in zones 6-7 and a little earlier in zones 8 and warmer. Ensure that you plant daffodils in the fall, about two to four weeks before ground freezes, to give them a chance to bloom in the spring.

Another flower that loves coffee grounds is cyclamens. These flowers make for an excellent display and attract a variety of pollinators. The blooms are also robust and contain oxalic acid, which deters rodents and deer. They also make a great cut flower. When they are growing in pots, they need to be separated from other plants. If you plan on displaying daffodils in a mixed display, you should plant them separately from each other.

Daffodils grow best when they receive adequate light. The most suitable locations for planting daffodils are sheltered and south-facing.


Coffee grounds are an excellent fertilizer for camellias, holly, and other acid-loving plants. They are also slightly acidic, which helps acidify soil. These grounds are better for your plants than commercial fertilizers. Holly plants are especially fond of acidic soil. Mixing some coffee grounds with your soil will help your camellias grow healthier and more lush foliage.

If you do not like coffee grounds, you can use the leaves of your native holly tree instead. Holly is an evergreen tree and deciduous shrub that grows naturally in temperate and tropical climates. It grows up to 18 metres tall, and its leaves are rich in caffeine. Holly is also known as yaupon holly, which grows wild throughout the Southeast and many coastal states. Native Americans steeped yaupon hollies and leaves in hot water to make a stimulating drink.

While it might not sound appealing, the leaves of holly are great for making a delicious tea. Make sure you air-dry the leaves before using them, as they contain toxic chemicals. Holly is often covered with a waxy coating to prevent animals from eating it. If you want to brew your own tea, use a tea infuser and use hot water. Avoid boiling the water, as this can make the tea bitter.

Holly is a drought-tolerant shrub that can tolerate light shade and full sun. It is best grown in well-drained soil with a pH that is neutral or slightly acidic. It also thrives in alkaline soil.

African violets

You can use coffee grounds to fertilize your African violets. They will appreciate this organic matter. African violets like bright, indirect light, and need to stay away from hot places. Once you’ve planted your African violets, they should grow to about eight inches tall and forty centimeters wide. After you’ve given them some time to establish, you can fertilize them with phosphorous every two weeks.

Coffee grounds can also be added to your compost pile. You can add a cup of grounds every week to keep your compost bin smelling nice. However, don’t use them to replace store-bought fertilizer. You’ll want to sprinkle the grounds in a light layer over the soil before adding them to the compost pile. This will prevent the grounds from burning your African violets.

You should also avoid feeding African violets with concentrated urine or manure. The urea in these products can burn the roots of the plants. The urea content in both fresh animal manure and urine can be reduced by waiting for them to rot. Adding a bit of bone meal to the soil can also help.

African violets need specific nutrients for good health. They need a certain ratio of nitrogen, phosphorus, potassium, and trace minerals. You can find commercial formulas to feed your African violets but you should remember that most of them use urea as a nitrogen source. Urea will burn the roots of your African violets, so use an organic fertilizer instead.


Coffee grounds are an established addition to home gardens as a nitrogen fertilizer. However, these grounds can alter the texture of soil, making it harder for clover to establish. In addition, they also have the potential to cause the growth of wood sorrel, which prefers acidic soil with low levels of nitrogen. So, if you want to use coffee grounds, you must apply them in a precise dosage.

Some people suggest using coffee grounds to prevent weeds. However, this is not an ideal method because you need to spread a very thick layer of mulch over the ground. It is not healthy for your plants. This idea stems from the belief that coffee grounds inhibit weed seed germination. While coffee grounds have the ability to inhibit clover germination, they have not been proven to have any effect on other weed seeds. Instead, you should follow recommended methods for weed suppression.

Another way to prevent clover is to keep your lawn mowed regularly. It is best to keep the grass height low. This will give the grass a slight edge over the clover. This method can be a great alternative to chemical weed killers. While some homeowners may not like the look of the white clover, it is not difficult to remove it.

Coffee grounds are a great slow-release fertilizer. However, it is important to make sure to test the acidity of your soil before adding coffee grounds to your garden. If the soil is too acidic, the resulting plants may be stunted.


There is some evidence that coffee grounds can help repel slugs and snails. This information comes from the OSU Extension Service. Coffee grounds contain antimicrobial properties, and they are known to suppress certain diseases and improve soil fertility. In controlled research, coffee grounds may also suppress some types of pathogens and affect plant growth and pH. Whether these benefits outweigh the risk of attracting pests is debatable.

Coffee grounds can help improve soil structure and drainage. The larger particles of coffee grounds allow water and air to easily penetrate the soil to the roots. They can also help attract worms, which turn organic matter into valuable nutrients for plants. While coffee grounds may not be a good addition to the soil, they can help plants grow faster.

Although coffee grounds may not be desirable for growing plants, they are an excellent source of nitrogen. They have an NPK value of 2.1-0.3-0.3, which is comparable to commercial single-ingredient organic fertilizers. In addition, they are neutral in pH. The acid content of coffee grounds is mostly leached out. They have a pH of 6.5 to 6.8, which means they won’t negatively impact the pH of your soil in moderate amounts.
