Are Coffee Grounds Good for Houseplants? (Explained)
Coffee grounds are often thrown away, but what can you do with them?
Did you know coffee grounds have been used as fertilizer for a long time?
So, in short, coffee grounds are good for plants. For houseplants, coffee grounds are an excellent source of nitrogen.
Therefore, plants benefit greatly from using coffee grounds as a source of fertilizer.
However, there are some potential downsides to using coffee grounds as houseplant fertilizer.
In the following paragraphs, we will delve into this topic in greater detail.
So, keep on reading.
Are coffee grounds good for your houseplants?
Coffee grounds are good for houseplants because they’re high in nitrogen and other micronutrients.
This makes them a great fertilizer for plants that need extra nitrogen, such as tomatoes, peppers, and roses.
However, you should be careful not to use too much coffee grounds on your plants.
Too much can cause the top layer of soil to grow mold and hinder oxygen getting into the roots of your houseplants.
The best way to use coffee grounds for houseplants is to dilute them with water.
It’s fine to apply coffee grounds directly to the soil as a mulch to help enrich the soil.
However, if you’re using them in your garden or on other plants that thrive in moist ground, it’s best to mix them with some calcium carbonate eggshells first.
This will help balance out the acidity in the coffee grounds and make sure they don’t harm your plants.
Coffee grounds also increase moisture content in the soil—which is why they work well for plants that like wetter conditions.
Do all plants like coffee grounds?
Not all plants like coffee grounds. In fact, some plants don’t like them at all and can be stunted by the grounds.
For example, succulents don’t do well with coffee grounds because they thrive in soil that is low in nutrients.
On the other hand, some plants love coffee grounds and will thrive when given them as a fertilizer.
Cacti are a great example of this: their natural environment is full of sand and gravel, so they love soils that are high in alkalinity (similar to coffee grounds).
Before you start using coffee grounds on your houseplants, it’s important to do your research first!
Not all plants enjoy the same things, so you’ll want to make sure you’re giving your plants what they need nutritionally.
Can I use too much coffee ground fertilizer on my plants?
It’s important to be careful with how much coffee grounds fertilizer you use on your plants.
Excess nitrogen can be harmful, and it’s easy to go overboard with this type of fertilizer.
Coffee grounds are a good source of nitrogen, so it’s tempting to apply them liberally.
However, over-fertilizing can cause problems like leaf scorching, which makes the leaves turn yellow and brown.
If you’re not sure how much coffee grounds to use, start small and increase the amount gradually until you find the right level for your plants.
You don’t want to put too much coffee grounds on top of the soil when using them as mulch.
This is due to the fact that coffee grounds can prevent oxygen and air from reaching the roots of your plants.
So, you may want to mix the coffee grounds with other types of fertilizer to reduce the risk of over-fertilization.
As long as you’re mindful of how much coffee ground fertilizer you apply, your plants should be happy and healthy!
