Short Answer
Calathea plants generally do not prefer coffee grounds, as they prefer well-draining, slightly acidic soil.
Coffee grounds can make the soil too acidic, which can be damaging to the plant.

For best results, it is recommended to use a potting mix with a slight acidic pH, such as an African violet mix.
What is a Calathea Plant?
A Calathea plant is an eye-catching perennial native to tropical regions of the Americas.
They are a popular choice for indoor houseplants because of their lush foliage and bright colors.
Calathea plants are typically known for their bold, striped leaves and vibrant colors that are a beautiful addition to any home.
They come in a variety of shapes and sizes, from low-growing varieties to tall, upright plants.
They thrive best in moist soil and prefer indirect sunlight and high humidity.
Some Calathea varieties are known to be picky when it comes to their care, so it is important to research the specific variety you plan to grow before making any decisions.
What are Coffee Grounds?
Coffee grounds are the remains of used coffee beans that are often discarded after brewing.
They are dark in color and have a very strong aroma.
While the grounds may appear to be a nuisance, the truth is that they are a valuable resource when used in the right way.
Coffee grounds are full of nitrogen, phosphorus, and potassium, which are essential elements in plant nutrition.
They also contain trace elements of magnesium, calcium, and sulfur which can help to improve the structure and fertility of soil.
Additionally, coffee grounds have been found to be a natural deterrent to some pests and can help to improve the moisture and drainage of soil.
As a result, many gardeners have found that using coffee grounds can be a beneficial addition to their garden.
Effects of Coffee Grounds on Calathea Plants
When it comes to using coffee grounds on Calathea plants, it is best to stay away.
While coffee grounds may be beneficial for other plants, they are not recommended for Calathea.
This is because coffee grounds are acidic, and Calatheas prefer to have moist, well-draining soil.
The acidic nature of coffee grounds can damage the plants and even cause the leaves to become discolored and wilted.
Additionally, Calatheas are very sensitive to their environment and require specific care.
Coffee grounds can be too harsh for their delicate roots and can cause root rot, a common problem among Calatheas.
The acidic nature of the grounds can also lead to nutrient deficiencies and stunt the growth of the plant.
To avoid any damage to Calatheas, it is important to avoid using coffee grounds as a fertilizer.
Instead, use a balanced fertilizer specifically designed for Calathea plants.
This will provide the necessary nutrients and help keep the soil balanced.
Additionally, it is important to water the plants regularly, as Calatheas thrive in moist soil.
With proper care, your Calatheas will remain healthy and vibrant.
What Other Uses are There for Coffee Grounds?
While coffee grounds may not be ideal for Calathea plants, there are still many other uses for them.
For example, coffee grounds can be used as a beneficial soil amendment in compost.
They are packed with nitrogen, which helps to break down organic matter.
This can provide a source of nutrients for plants in the garden.
They can also be used as a fertilizer for other plants, such as tomatoes and peppers.
Coffee grounds can help to improve the soil structure and retain moisture, making them an excellent choice for gardens.
Additionally, coffee grounds can be used as a natural pest repellent.
Sprinkling grounds around the base of a plant can help to deter ants and other insects.
Finally, coffee grounds can be used as an effective mulch, helping to keep the soil moist and cool in the summer months.

The soil should also be slightly acidic, with a pH of around 6.
5.
It is important to use a soil mixture that is specifically designed for Calathea plants, as this will ensure that your plant is getting the best possible care.
The soil should be high in organic matter, such as peat moss, compost, or finely-ground bark.
These materials will help the soil retain moisture and provide essential nutrients for your plant.
Additionally, perlite or vermiculite can be added to the soil to give it better drainage and aeration.
It is important to remember that Calathea plants do not like to be over-watered, so it is important to use a soil mixture that will not become compacted or waterlogged.
The soil should be allowed to dry out slightly between waterings, and should not stay soggy for extended periods of time.
Additionally, fertilizers should be used sparingly, as Calathea can easily be burned by too much fertilizer.
A well-balanced fertilizer specifically designed for Calathea plants should be used to ensure that your plant is getting the nutrients it needs.
When it comes to using coffee grounds for Calathea, the answer is a definite no.

When to Fertilize Calathea Plants
Calathea plants, while beautiful and popular, require careful care and attention.
One of the most important aspects of Calathea care is fertilization.
Because Calathea plants are native to tropical rainforests, they require a nutrient-rich soil in order to thrive.
A balanced fertilizer specifically designed for Calathea plants should be used regularly to provide the necessary nutrients for the plant to grow and flourish.
Fertilizing Calathea plants should be done on a regular basis, usually once a month during the growing season (April through September).
During this time, the plants will be actively growing and need the extra nutrition.
However, it is important to note that Calathea plants do not require heavy doses of fertilizer and can actually be easily damaged by too much.
Therefore, it is best to use a weaker fertilizer or a fertilizer that is specifically designed for Calathea plants.
