How Often Should You Put Coffee Grounds on Roses

A steaming cup of coffee not only awakens our senses but may also breathe life into our beloved rose gardens. The very grounds that provide the base of our favorite morning beverage also lay the foundation for flourishing roses. Utilizing both fresh and used coffee grounds, this ancient method of tending to roses unlocks various benefits, extending to soil health, growth, and disease prevention. But how often should you put coffee grounds on roses? The answer may surprise and delight both coffee enthusiasts and gardeners alike. In this comprehensive article, we will explore everything from the soil’s pH balance to the creative ways coffee grounds can be used to nourish your roses. Let’s delve into this invigorating topic.

Fresh and Used Coffee Grounds for Roses– a Matter of pH

Understanding the soil’s acidity is crucial in gardening, and coffee grounds play a pivotal role in this aspect. Fresh grounds are acidic, suitable for acid-loving plants, whereas used coffee grounds have a more balanced pH, making them an excellent option for roses. Regularly testing your soil’s acidity ensures you are using the right type of coffee grounds in the right amount.

Can You Feed Fresh Coffee Grounds to Roses?

Fresh coffee grounds, with their acidic nature, are not typically recommended for roses. Roses prefer a neutral to slightly acidic soil, and adding fresh grounds might upset this delicate balance. If your soil is already too alkaline, a small amount of fresh grounds may help; otherwise, used coffee grounds are a great way to nourish roses.

Adding coffee grounds to roses can be done in several creative ways. You can scatter them around the rose bush to slowly release nutrients, mix them with sand to improve soil structure, or add them to your compost pile to enrich compost tea. Combining coffee grounds with other organic matter like epsom salts can create a nutrient-rich layer to nourish the roots of the roses.

Can you put too much coffee grounds on roses?

Yes, using too much coffee grounds on roses can lead to problems. A thick layer of coffee grounds may hinder water drainage, affect root development, and create an imbalance in soil nutrients. Salt buildup is also a concern if overused. Following the good rule of a thin layer and monitoring the soil’s health ensures that you are using the right amount.

Do you just sprinkle coffee grounds on plants?

Sprinkling coffee grounds around plants, including roses, is a common practice and a great way to slowly release essential nutrients into the soil. However, it’s just one method. Coffee grounds can also be mixed with other organic material or used as mulch to improve soil structure and drainage.

Do you use fresh or used coffee grounds for roses?

Used coffee grounds are typically recommended for roses, as they have a more balanced pH that aligns with the needs of rose plants. Fresh coffee grounds are more acidic and might not be suitable unless the soil is too alkaline. Regularly testing the soil’s pH will guide you in choosing the right type of coffee grounds for your roses.

Is leftover coffee good for roses?

Leftover coffee can be beneficial for roses when used in moderation. By diluting it with water, you can create a nutrient-rich solution that provides nitrogen, potassium, and other essential nutrients. This diluted coffee can be used to water the rose plants occasionally, providing an additional boost to their growth.

Which plants do not like coffee grounds?

While coffee grounds are beneficial for many plants, some do not respond well to them. Plants that prefer alkaline soil, such as lavender and clematis, may not thrive with coffee grounds as they tend to make the soil more acidic. Overusing coffee grounds may also negatively affect certain types of indoor plants. Understanding your plants’ specific needs and preferences will guide you in using coffee grounds in the right way, and with the right care, to nurture your garden.


Coffee grounds, with their richness in nutrients, texture, and even caffeine, can breathe life into your rose garden. Whether scattered as mulch, mixed with sand, or brewed in compost tea, they offer a unique and natural way to enhance your roses’ growth and blooms. Following the right methods and understanding the seasonal needs ensures that this cup of care can lead to thriving plants and gardens.
