If you are a coffee lover, you must be familiar with coffee grounds. Coffee grounds are reusable! Reusing coffee grounds is a great, effortless way to do eco-friendly gardening to nourish houseplants. Take a closer look at how to reuse coffee grounds to fertilize houseplants:

Why Use Coffee Grounds for Compost?

Organic matter is present in coffee grounds, while nitrogen, potassium, and phosphorus are favorable to growth. When applied properly, coffee grounds can:

  • Improve soil structure, improving water retention and drainage
  • Slowly release nitrogen, giving your plants a consistent source.
  • The coffee-rich soil helps develop a healthy root by harboring useful bacteria.
  • Reusing coffee grounds is environmentally sensitive because most grounds are headed to landfills.

How to Grow Houseplants by Using Coffee Grounds?

While coffee grounds have numerous benefits, they need proper preparation to avoid harming your plants. Here’s how:

  • After brewing coffee, lay the grounds on a baking sheet and let them air-dry for a day or two. This prevents mold and makes them easier to store.
  • Coffee grounds are slightly acidic. Excessive use can lower soil pH, which may not suit all houseplants. Balance is key.
  • Mix coffee grounds with compost, potting soil, or sand to dilute the potency and ensure even nutrient distribution.

How to Use Coffee Grounds for Houseplants

Coffee grounds can be mixed with brown materials, like cardboard or dried leaves, and composted into a nutrient-rich green compost perfect for houseplants. Ground coffee can also be used as an organic mulch to keep things moist and suppress weeds. Don’t apply too much as it can compact the soil and reduce aeration.

To not burn excess nutrients, mix with potting soil to avoid this. Great for houseplants that love nitrogen, like Pothos, Philodendrons, and Ferns. Steep old coffee grounds in water for a day or two, make a mild fertilizer, and use it to water houseplants; great to give a little nutrition boost without over-fertilizing the soil. You can fertilize your houseplants with some other fertilizers too.

Plants That Love Coffee Grounds

While coffee grounds and many plants, not all houseplants thrive with their use. Some benefits the most, are given below:

  • Nitrogen-loving house plants like monstera and ferns grow well with compost consisting of coffee grounds.
  • African violets and peace lilies can benefit from the gentle nutrient release.
  • Growing herbs or vegetable plants indoors, and coffee grounds can improve soil fertility.

Plants That Don’t Love Coffee Grounds

Certain plants prefer more alkaline soil and may not respond well to coffee grounds. Succulents and cactus plants prefer dry, sandy soils devoid of organic matter, while carnivorous plants do well in low-nutrient soils, while palms and spider plants can be quite sensitive to acidic environments.

Common Mistakes to Avoid

Avoid these common mistakes:

  1. Excessive coffee grounds can create overly acidic or compacted soil.
  2. Always use brewed grounds, as fresh ones are highly acidic and can harm plants.
  3. Wet grounds can harbor mold, which may spread to your houseplants.
  4. Not all houseplants thrive with coffee grounds. Always research your plant’s specific soil and nutrient requirements.

Creative Ways to Reuse Coffee Grounds

If you have more coffee grounds than your houseplants need, don’t let them go to waste! Keep ants and snails at bay by sprinkling used coffee grounds around plant bases. You can mix coffee grounds with soil for a nutrient-dense medium. Coffee grounds are an excellent addition to vermicomposting containers, as worms love them.
