Coffee grounds make the soil acidic that is good for the string of pearls.

When added to the compost, coffee grounds can bring in microorganisms that are beneficial for the soil. So, you can add the coffee grounds to other organic matter to create compost for your string of pearls.

Best way to use coffee grounds on string of pearls

Coffee grounds can boost your plant’s growth and add nutrition to it if used correctly.

But many plant owners make the mistake of adding the coffee grounds directly to the plant’s soil. That is not the correct way of using coffee grounds and can damage the plant in the long run.

Adding coffee grounds to the soil directly can cause fungal growth and attract pests, so you should use some other method of adding coffee grounds to your plant.

There are three ways of adding coffee grounds to the soil so that the plant benefits from it. Let’s find out what these three methods are.

  1. Liquid fertilizer
  2. Mulch
  3. Compost

Now let’s understand these in detail.

As a liquid fertilizer

One of the best ways to use coffee grounds is by making a liquid fertilizer out of them. You can use the following steps if you want to make liquid fertilizer with coffee grounds.

  1. Fill a container with water. Let the water simmer.
  2. Turn the gas off when the water starts simmering. Let the water sit for some time.
  3. Add coffee grounds to the water after 5-10 minutes.
  4. Now leave the mixture for few days and stir it every few days.
  5. Strain the water and fill it in a spray bottle to use on the houseplants.

The coffee grounds break down and add nutrition to the water when you let it sit there for few days. After the nutrients have mixed well with the water, you can use it on your string of pearls.

You need to check how your plant reacts after applying the liquid fertilizer to it. If the plant responds well, you can keep spraying the liquid fertilizer once a month to boost the growth.



As a mulch

Mulching is mainly used for outdoor plants but can be used for indoor plants as well. Mulching can be beneficial for the soil as it retains moisture, adds beneficial bacteria and microorganisms, and fertilizes the soil.

Mulching is when you add and mix some organic matter and use it as a cover on top of the soil.

You can prepare mulch by mixing organic matter such as branches, leaves, straw, etc., and add some coffee grounds to it. It would be ideal if you will be careful while using mulch on your houseplants as it can change the soil’s pH level that might be damaging for the plant.

As a compost

Composting is another great way to use coffee grounds on your string of pearls. The coffee grounds alone can’t provide all the required nutrients, so mixing them with other elements will help provide all the necessary nutrients for the plant.

Coffee grounds add nitrogen to the soil that is very beneficial for the plant. You can mix 15-20% coffee ground with the organic compost along with the other elements.

You should avoid adding too much coffee as that can increase the acidity of the soil. And you should keep the compost light and dry so that it doesn’t retain too much water in the soil.

It would be best if you do not go overboard with composting as that can have harmful effects on the plant. You should use the compost to fertilize your string of pearls once every six to eight weeks and see how the plant reacts.

Hazards to keep in mind while using coffee grounds in the string of pearls

Coffee grounds can have their benefits, but we should look at the hazards of using coffee grounds on the string of pearls.

Coffee grounds can have harmful effects if you are using them incorrectly, such as adding them directly to the soil or using them in a large quantity.

So the first thing that you should keep in mind is that you need to use coffee grounds in the appropriate way that doesn’t turn out to be harmful to the plant and avoid using a large quantity.

Pest infestation

Coffee grounds can be excellent in keeping away some pests from the plant, but they can also attract some pests such as gnats or flies.

Pests infest your plant when you add coffee directly to the soil. These pests slow down the growth of the plant. Therefore, you should use coffee grounds as liquid fertilizer or mix it with compost instead of adding it directly to the soil.

Fungal diseases

Just like pest infestation, adding coffee grounds directly to the soil can cause fungal growth in plants.

The coffee grounds will take time to break down and add nutrition to the soil, but the fungus will infect your plant in the meantime and damage it.

The fungal growth not only stops the growth of the plant but also causes other problems. Therefore, you should skip adding coffee grounds directly to the topsoil. You can use coffee grounds as compost, mulch, or liquid fertilizer to be on the safe side.

Retains moisture

The string of pearls likes well-draining soil that doesn’t retain excess water and allows airflow between the soil and the roots.

Coffee grounds can retain moisture for an extended period that is not ideal for the string of pearls. Adding coffee grounds directly to the soil adds a layer that holds water in the soil.

If you end up overwatering the plant and adding coffee grounds, it will be a deadly combination for the plant. It will lead to root rot and other diseases in your string of pearls.

Even when using coffee grounds as compost, if you add too much coffee grounds, it will retain excess moisture. So you should use the right amount of coffee grounds when creating compost for the string of pearls.

Inhibits the growth of the plant

Adding coffee grounds directly to the topsoil can hamper the growth of the plant or even stop it.

Researches show that adding coffee grounds, especially to young plants, can be harmful to them. So you should avoid using coffee grounds when you have a young string of pearls.

Should I water my string of pearls with leftover coffee?

It is best to avoid watering your string of pearls with leftover coffee. It might not be the best option because the concentrated caffeine in the coffee can hinder the plant’s growth.

You might end up overwatering the plant if you start watering with coffee, and the string of pearls hate overwatering and appreciate soil that doesn’t hold too much water.
