Diluted Coffee For Plants: Can You Water Plants With Coffee

The first thing to understand is that coffee is very soluble in water. So, if you are going to use it as a plant food, you need to dilute it with something else before using it on your plants. The most common way of doing this is by adding some fruit juice or milk (or even plain water) into the cup of coffee before drinking. If you want to make your own coffee at home, then you can just add one tablespoon of sugar or honey into the cup of coffee before drinking.

If you don’t have any other option, then there is another method that works quite well too. Diluting coffee with water is a great idea if you plan to drink it straight away. Just put a little bit of water in the cup and pour out some of the remaining liquid from the bottom until all remains is 1/4 cup. Drink it right away!

However, if you are planning to use it on your plants later, then you will need to dilute it further. This means putting some of the diluted coffee in a container and placing the container somewhere where the temperature stays between 30°C and 35°C. Then place the container inside a warm room for around 24 hours. After that, take out the container and let everything dry out completely before reusing it again.

Finally, if you are using instant coffee, it is not going to be as effective for your plants. The coffee grounds and the added sugars and syrups found in the instant coffee variety tend to make your plant food less effective.

However, you can make your plant food more effective by adding some fertilizers to it before watering your plants with it. Things like bone meal and rose food are known to increase the effect of the plant food that you are making.

Which plants like coffee?

When it comes to plants, many people believe that most plants should not really come into direct contact with coffee and its oils. However, this is not entirely true and there are many plants out there which do just fine when you water them with coffee. These include but are not limited to:

• African Violets

These plants tend to do especially well with coffee plant food. For best results, make sure you water it with diluted coffee before giving it to the plant. As a result of this, you should find that your African violet is going to grow denser and have a lot more flowers.

• Spider Plants

As long as you use coffee grounds on these plants, they will thrive very well in bathrooms or any other areas where there isn’t enough natural light. You can also water them with coffee to give the plants enough nitrogen to allow them to grow very well.

However, there are some plants which don’t do as well with coffee plant food. These plants include but are not limited to:

• African Violets

While these plants do fine when watered with coffee, they tend to not react well to the oils and dregs that are left over after you have finished drinking your cup of coffee. As a result of this, you should avoid watering these plants with coffee if you want to make them grow very well.

However, you can still give them coffee plant food and they will still grow okay. You just need to keep in mind that you need to dilute the coffee when you are watering the plant with it. This is due to the fact that African violets like their soil to be on the alkaline side.

Furthermore, you can also use coffee grounds on these plants as a mulch. This will help them in many ways and will give them the nutrition that they need to flourish. You simply need to wait until the oils have dissipated before applying them directly to the soil.
