Coffee grounds are acidic, so they should be reserved for plants that like acid. Coffee grounds could stunt the growth of plants that need it the most if your soil is already high in nitrogen. “If you’re growing a lot of nitrogen-fixing plants, you might want to consider using a coffee ground instead of a nitrogen fertilizer,” Coffey .

Are there any plants that don’t like coffee grounds?
Some of these plants include; century plant, lavender, pothos, orchids, sago palm, yucca, rosemary e.t.c. These plants do not like acidic soil and coffee grounds and can be toxic to fish and other aquatic life if they are added to the soil. Coffee grounds can also be used to fertilize your garden.
Which plants like leftover coffee?
Coffee is a great source of nitrogen, and plants that enjoy more acidic soil can benefit from certain levels of nitrogen, like azaleas and rhododendrons. If you plan on doing this, you will need to keep an eye on how much nitrogen your plants are getting from the soil. If they’re getting too much, it could be a sign that they need more nitrogen in their diet.
You can also add a little bit of compost to your potting mix to help with the nitrogen absorption. Another option is to use a soil amendment that contains nitrogen-fixing bacteria, such as Bacillus thuringiensis (Bt), which is commonly used in organic gardening. Bt has been shown to be effective in increasing nitrogen uptake in soil, but it’s not recommended for use in the home garden.
How often should you put coffee grounds on plants?
Don’t add too many at once, because the acidity could bother your worms. For a small worm bin, a cup or two of grounds per week is ideal. In addition to using coffee grounds in your worm bin, earthworms in your soil will also be more attracted to your garden when you use them mixed in with your compost.
If you have a large garden, you may want to consider adding a few worms to the soil at a time. This will help keep the worm population in check, and you’ll be able to see how many worms you’re adding to each bin. If you do this, be sure to add the worms at the same time each week, so you can see if they’re getting enough food.
When should I put coffee grounds on plants?
If you don’t have enough green material, the compost pile won’t heat up because the microorganisms don’t have enough energy to do their thing. ‘After about three months your old coffee grounds will have been transformed into nutrient-rich compost giving you the best of both worlds,’ he .

Should you share a cup of coffee with your plants?
Plants that thrive in low-nitrogen environments can be helped by the nitrogen found in coffee grounds.
“Coffee grounds have a lot of nitrogen in them, and that nitrogen can be used by plants to make their own nitrogen-fixing compounds,” said Dr. Michael J. O’Connor, a professor of plant pathology at the University of California, Davis, who was not involved in the study.
Where do you put coffee grounds in the garden?
It’s said to repel cats, fertilize soil, kill slugs and keep weeds at bay if you spread on planting beds like mulch. A coffee mulch is said to bring earthworms and acidify the soil. Other gardeners work coffee grounds into beds to aerate and acidify the air.
Coffee grounds can also be used as a soil conditioner, helping to prevent soil erosion and improve soil structure. Coffee grounds also help to improve the soil’s pH, which is a measure of how acidic or alkaline it is. The higher the pH value, the stronger the plant’s ability to absorb water and nutrients.
Do tomato plants like coffee grounds?
Coffee grounds are very important for the growth of tomato plants because they contain 2% nitrogen and varying amounts of phosphorus and potassium. By mixing some coffee grounds into the soil below your tomato plants you’re increasing the amount of nitrogen available to your plants, which in turn will help them grow faster.
