Do Succulents Like Coffee Grounds.


Coffee is a popular beverage millions of people enjoy as a stimulus for when you need a boost in the morning. Most of the time, the coffee grounds after making your coffee are tossed out. But did you know that coffee grounds also can be used to improve your succulent’s soil nutrient content and health?

Coffee grounds are rich in nutrients such as nitrogen, phosphorus, and potassium. These compounds improve the soil structure and water retention. Using coffee grounds in your succulent soil reduces waste, saves money, and provides the needed nutrients for your plants.

Succulents are low-maintenance plants and can survive extreme weather conditions. However, to ensure the healthy growth of succulents, it is essential to provide them with the proper nutrients.

This post will explore the benefits of using coffee grounds as fertilizer and nutrients for succulent soil.

Are coffee grounds good for succulents?

Coffee grounds are a natural and organic source of essential nutrients that benefit your succulent soil. Here are the compounds in the coffee that provide the needed nutrients to your soil:

Nitrogen: Nitrogen is one of the most vital macronutrients plants need to grow. It plays a crucial role in photosynthesis production. Coffee grounds contain 2% nitrogen that is slowly released into the soil.

Nitrogen helps in the growth of leaves, stems, and roots and can make your succulent look greener and lusher. Nitrogen deficiency on succulent leaves is indicated by the leaves turning green to yellowish. The oldest leaves are affected first, but the whole plant may be yellow in severe cases.

Phosphorus: Phosphorus is an essential macronutrient that plants need for root development. The nutrients are necessary for the development of a strong root system. Phosphorus is also beneficial during seed germination for succulent seedlings.

Coffee grounds contain about 0.3% phosphorus, which benefits your succulents. 

The reddish-purple color on the leaves indicates phosphorus deficiency in succulents. The oldest leaves are affected first. The plants are usually stunned. Phosphorous deficiency is common in overwatered succulents, and the soil is always wet.

Potassium: Potassium is a macronutrient that is essential for plant growth and health. It regulates water movement in the plant and plays a crucial role in developing flowers and fruits. 

Coffee grounds contain approximately 0.4% potassium, which can benefit your succulent plants. Potassium helps grow strong stems and roots, making your plants more robust and disease-resistant. 

Potassium-deficient succulents become gray and tan near their leaf margins. The oldest leaves become affected first. Potassium deficiency is common in sandy soils and soils low in native potassium.

Too much potassium does cause the salt burn. Soils with high potassium levels can induce magnesium deficiency.

Magnesium: Magnesium is a micronutrient essential for plant growth and development. It is responsible for the production of chlorophyll and helps in the absorption of other nutrients.

Coffee grounds contain approximately 0.1% magnesium, which can benefit your succulent plants. Magnesium helps in photosynthesis and can make plants look more vibrant and healthy.

What are the benefits of coffee grounds to succulent soils?

The nutrients provided by coffee grounds can benefit succulent soil in several ways. Here are some of the benefits:

Improved Soil Structure

The organic matter in coffee grounds can help improve the structure of the soil. It can increase soil porosity, allowing air and water to penetrate quickly and enhance soil drainage. This can be particularly beneficial for succulent plants that require well-draining soil.

Increased Nutrient Availability

The slow-release nature of the nutrients provided by coffee grounds can ensure that your succulent plants get a steady supply of essential nutrients. This can promote healthy growth and ensure the plants have all the nutrients they need to thrive.

pH Regulation

Coffee grounds are slightly acidic, with a pH of around 6.5. This can benefit succulent plants, as they prefer slightly acidic soil. The acidity of the coffee grounds can help regulate the pH of the soil, making it more suitable for the growth of succulent plants.

Pest and Disease Resistance

The nutrients coffee grounds can make your succulent plants more resistant to pests and diseases. For example, calcium can strengthen the plant’s cell walls, making it more resistant to pests and diseases. 

Potassium can also promote disease resistance, while nitrogen can help promote healthy growth and make plants more resistant to pests.

How to Use Coffee Grounds in Succulent Soil?

Use in Moderation: While coffee grounds can benefit your succulent plants, it is essential to use them in moderation. 

Using too much coffee grounds can make the soil too acidic and affect the pH balance of the soil, which can harm your plants. A good rule of thumb is to use no more than 20% coffee grounds in your soil mix.

Watering: Coffee grounds can also be added when to watering your succulent plants.

Add a small amount of coffee grounds to the water and let it sit for a few hours before watering your plants. This can provide a slow release of nutrients to the plant and help regulate the pH of the soil.

Composting:  Coffee grounds are an excellent nitrogen source essential for composting. Add coffee grounds to your compost pile and other organic materials such as fruit and vegetable scraps, yard waste, and eggshells. 

Mix the materials and let them decompose over time. The end result will be a nutrient-rich compost that can be used to fertilize your garden.

Mulching: Coffee grounds can also be used as mulch around your plants. Mulch helps to regulate soil temperature, retain moisture, and suppress weed growth. 

Sprinkle a thin layer of coffee grounds around the base of your plants and gently work them into the soil. Be sure to keep the coffee grounds away from the stem or trunk of your plants to avoid any potential damage.

Using coffee as fertilizer and nutrients for soils is a sustainable and cost-effective approach to gardening. Coffee grounds are rich in nutrients, improve soil structure, and attract beneficial organisms.

Using coffee as fertilizer and soil nutrients can promote a healthy garden ecosystem and reduce waste. So the next time you make yourself a cup of coffee, don’t throw away those grounds – use them to boost your succulent garden.
