Is instant coffee good for houseplants?
If what you want is to fertilize the land so that your plants grow better, then instant coffee is perfect for plants. Coffee contain a great source of nitrogen and minerals, which give its peculiar brown color and in ecological terms, coffee are considered a green composting material.
There are two ways to use instant coffee on houseplants:

- Directly : if you want to pour it directly on the ground, you must make sure that the instant coffee are already dry, otherwise they could rot and damage the plant.
Which plants to fertilize with instant coffee?
Before you can use the instant coffee as fertilizer, you should let them cool down and dry otherwise it can quickly happen that the moist coffee grounds start to mold. It dries best if you spread it out on a flat plate and leave it overnight, for example.
With balcony flowers and potted plants, before repotting, lift the instant coffee under the new potting soil so that they are distributed and not just remain on the surface, where they cannot supply the plants with nutrients.
If you want to use the instant coffee mixed into the compost as fertilizer, it is sufficient to sprinkle the coffee grounds on the surface of the compost heap.
The following applies to indoor plants: do not fertilize them, but let the coffee cool down after brewing and water the plants diluted with water in a ratio of 1:1. Depending on the needs of the plant, half a cup per week is sufficient.
As you can see instant coffee is not good for all plants. Its properties are in fact extremely beneficial for some vegetables, while they could be a problem for others.

As you can see in the table above, fresh coffee tends to lower the pH of the soil and make it more acidic. It can therefore help you when growing acidophilic plants, such as berries or basil.
It can even help you balance the effects of ash, which tends to raise the pH of the soil. However, you need to be careful if the soil is already acidic, or if you are growing plants that prefer a neutral pH.
Nitrogen stimulates the development of leaves and all green parts, which is important. But when it is too much, you risk that the plants will produce many leaves and very few fruit. That’s why it’s best not to use too much coffee with tomatoes, despite being acidophilic plants.

Conclusion
One way or another we could conclude that yes, instant coffee is good for plants . In this way, you can use the instant coffee as fertilizer for tomatoes, olive trees, geraniums, lemon trees or cacti, among others.
Coffee grounds as a fertilizer for houseplants is only recommended to a limited extent: it decomposes very slowly on the root ball and often begins to mold.
If you are lucky enough to be able to grow vegetables and fruit in your garden , then you should know that in this case too, instant coffee can come to your aid. In addition to saving on the cost of fertilizers and chemical fertilizers, you can use an entirely natural product.
Not everyone knows that coffee promotes the growth of carrots and radishes : it will be necessary to simply add the coffee to the seeds of these vegetables during the sowing phase.
The coffee grounds fertilizer is particularly suitable for plants that prefer a humus-rich soil.
However, coffee also has a soil acidifying effect, which does not benefit all plants – the fertilizer can even damage acid-intolerant plants.
Many garden plants – such as peonies, rhododendrons, ferns or hydrangeas prefer acidic humus soil, so you can easily fertilize them weekly with coffee grounds.
However, there are also many plants that thrive better on calcareous soil: these should not be fertilized with coffee powder.
The same also applies to seedlings and young plants, which are very sensitive.
Although coffee is good for plants, not all plants tolerate liquid coffee , because liquid coffee filters much more quickly into the ground and can damage some of plants.
Therefore, before you venture to use that liquid coffee, find out about the type of plants you have and if they can properly digest coffee in this state.
