Using Coffee Grounds on Succulents: What it actually does

What Do Coffee Grounds Contain?

Succulents benefit from the use of coffee grinds in their growth and development. Additionally, it will improve the soil’s richness.

When coffee grounds are added to succulent soil, both drainage and aeration are improved. Additionally, it raises the amount of organic matter in the soil, which improves the availability of nitrogen while giving the succulent the nutrients and minerals it needs for healthy growth.

Nitrogen is crucial for the growth of the plant and coffee grinds will increase the production of it.

More factors, such as type, quantity, brewed or unbrewed coffee, and other topics covered in this article, should be taken into account when using coffee grinds on succulents.

What Do Coffee Grounds Contain?

Many of the critical elements that are favorable for the growth of succulents are typically found in coffee grounds.

Coffee grinds typically contain:

  • Nitrogen at 2% (N)
  • potassium at 0.6 percent (K)
  • phosphorous content of 0.06 (P)

On the mineral scale, there is a minuscule quantity of

  • Calcium (Ca)
  • Magnesium (Mg)
  • Boron (B)
  • Iron (Fe)
  • Zinc (Zn)

The mineral composition of the grounds will vary depending on where in the world they were produced.

They will nevertheless consume roughly the same amount of macronutrients (NPK).

All of these nutrients are necessary for plants to develop and function normally, and succulents are no exception.

The Benefits of Using Coffee Grounds on Succulents:

Improves Soil Quality: Adds Nitrogen (N)

By increasing the ratio of nitrogen in the soil, using coffee grinds on succulents will help you improve the quality of the soil (N).

The most important component thought to be restricting plant growth is nitrogen. It is in charge of making chlorophyll.

Chlorophyll is crucial for absorbing light during the photosynthesis process.

Coffee grinds can boost photosynthesis and chlorophyll development in the soil.

Additionally, the inclusion of additional ingredients in the coffee grounds enhances the soil’s profusion.

Soil Drainage:

Coffee grounds would improve the soil’s ability to drain.

The richness of the soil and the increased production of microorganisms from the coffee grinds could both improve the soil’s ability to drain.

Soil Aeration:

The process of using coffee grounds on succulents to improve soil aeration and the soil winch’s ability to exchange gases.

So the plant would simply obtain the necessary gaseous form as a result of the soil aeration.

Soil aeration would increase both the activities of the plant and the growth of the plant body in this way.

Soil pH:

The pH of most coffee grounds is 7.0, which is neutral.

However, there are a few rare instances where coffee grinds can interfere with the soil’s pH, causing the pH to decrease.

Unbrewed coffee, which can actually recycle the pH of the soil, is mostly linked to this.

For plants that like acidic soil, the lower pH can be useful.

However, used coffee grounds generally keep the pH level of the soil for succulents pretty stable.

The reasonably priced Trazon Soil 3-in-1 Meter can be used to measure the soil’s pH and moisture content. It checks the pH as well as the amount of moisture and light. Clicking here will take you there!

Can Too Many Coffee Grounds Harm Succulents?

Yes, too many coffee grounds would prevent the succulents from developing and germination.

Fertilizers with less nitrogen concentration are ideal for succulents.

A delicate equilibrium within the natural environment of soil is necessary for the healthy development and proper operation of plants.

If there is an excess of nitrogen in the soil, using coffee grounds as fertilizer can enhance the ratio of nitrogen in the soil.

A highly high nitrogen content in the soil can cause nutritional lockup, lanky growth, stunted root growth, and an increase in soil mineral salts.

For a more thorough explanation of how adding organic matter to the soil impacts the availability of nitrogen for plants, see our in-depth article on mulching the soil.

Nitrogen Toxicity:

The University of California academics Sham S. Goyal and Ray C. Huffaker underlined the potential harmful effects of extremely high nitrogen levels on plant growth in their research publication.

A specific kind of nitrogen or a particularly high nitrogen content in the soil can both cause nitrogen poisoning.

Nitrogen can have a variety of effects on plants, especially succulents.

Continuous nitrogen exposure during the early stages of germination can seriously harm a plant’s physiological development.

Therefore, give it some thought before you add coffee grinds to your younger, still-developing succulents.

Leggy Growth:

As was already mentioned in the article, nitrogen in coffee grounds can accelerate the growth of succulents.

Coffee grounds may raise the nitrogen ratio in the soil, causing your succulents to produce a lot of new growth too quickly.

The natural growth pattern of succulents will be disrupted by too much nitrogen, resulting in their lanky growth (etiolation).

Sunlight exposure can also contribute to leggy growth in succulents. Your succulents begin to grow lanky in quest of sunlight when they don’t receive enough sunlight.

A more thorough explanation of how light affects plants will be provided in our post on what produces a leggy monstera.

As a result, if you notice that your succulents are becoming leggy, check the fertilizer’s nitrogen content and place them in indirect, bright sunshine.

Using Brewed and Unbrewed Coffee Grounds:

The Benefits of Using Coffee Grounds on Succulents:

Coffee grinds can be applied to succulents in both brewed and unbrewed forms. We have briefly outlined which option would be preferable below.

Brewed Coffee Grounds:

For all kinds of succulents, using coffee grounds from freshly brewed coffee is preferable. Brewed coffee is coffee that has had hot water added to it.

It would continue to make the soil neutral. It might not be the root cause of acidity in the plant’s soil.

Its ability to keep insects and pests away from the succulent plant body is one of its key advantages.

Numerous insects’ activity that might destroy the succulents would also be hampered.

Unbrewed Coffee Grounds:

Many different plants can benefit from unbrewed coffee grounds. But compared to that of the brewed coffee grounds, it is less beneficial.

The unbrewed coffee grounds wouldn’t be able to neutralize the soil, which is why.

Unbrewed coffee grounds actually lower the pH of the soil, making it unsuitable for succulent growth.

How To Use Coffee Grounds on Succulents?

Use coffee grounds in the plant’s planting area’s exposed soil.

Never use coffee grounds on succulent plants that are housed in planters. since the impact would be the least.

One thing you must keep in mind while using coffee grinds is not to pour or apply excessive amounts on the plant’s soil.

The plant might be harmed rather than protected from insects or other pests.

Can Coffee Grounds Prevent Pests?

Yes, coffee grounds—both brewed and unbrewed—can be quite effective in reducing pests and bugs.

Low pH can weaken or harm an insect’s exterior covering, making it fragile and prone to collapse, just like in the case of unbrewed coffee grounds.

Thus, by utilizing coffee grounds, you may protect your succulent plants from environmental hazards like pests and wasps, which will lengthen their healthy lifespans.

Around the world, coffee grounds are utilized to help propagate and feed succulent plants.

If you’re considering putting coffee grinds on succulents, keeping the factors outlined in this article in mind might help you make wiser choices.

The Takeaway:

Succulents may benefit from the addition of coffee grinds since it enriches the soil with macronutrients and NPK.

When utilizing unbrewed coffee grounds, there are some pH issues that should be taken into account because, if you’re not careful, they could cause the pH of the soil to decrease.

The conclusion is that, when applied properly, utilizing coffee grounds can actually improve the general health of succulents.


Do succulents like eggshells?

Definitely. In order to flourish, plants require calcium just as much as they do phosphate and nitrogen. Additionally, using eggshells as fertilizer is a great way to feed your succulents and cacti calcium carbonate.

What plants benefit from crushed egg shells?

According to Savio, shell fertilizer is particularly beneficial for plants like tomatoes, peppers, and eggplants. The additional calcium will assist in avoiding blossom-end rot. In addition to being calcium-rich, broccoli, cauliflower, Swiss chard, spinach, and amaranth may use more calcium from eggshells.

Do coffee grounds help succulents?

The decomposition of the used coffee grounds will enrich the soil with nitrogen, a crucial component for succulents. Along with improving drainage and aerating the soil, they may also reduce weeds and deter pests.
