They Are Used As Natural Pesticides
Coffee grounds contain certain toxic compounds, they include diterpenes and caffeine that repulse insects and pests.
The rough grain of coffee grounds keeps away pests especially slugs and ants from attacking the plant.
To use coffee grounds as a natural pesticide sprinkle them in the garden around the plants or set them in a container and place them in outdoor areas.
Dont Let Your Pets Around An Indoor Garden With Coffee Grounds
Slugs arent the only creatures that dont like coffee grounds. If you have a dog or cat who gets curious around your houseplants and they happen to take a big ol bite, you could accidentally make your pet very sick.

Some of the minerals contained in coffee grounds are essential to plants growth, in fact they are very, very rich in the following:
You have NPK . Talking of nitrogen, 2% of all the volume of coffee grounds is made up of this most fundamental of nutrients! And thats a lot!
But you also get some of those nutrients plant need in lower quantities but that are essential for their health, like magnesium and calcium. Finally, you also get some rare minerals like chromium.

Why Is Coffee Good For Plants
Some plants benefit from extra nitrogen and potassium. And coffee grounds being added to the soil, can supply this in the same way you would from a fertilizer.
In particular some plants like a more acid growing environment. And left over, cold black coffee can bring up the acidity levels. So acid loving plants can benefit from being watered with left over, cold black coffee. If it is really strong coffee, just water it down a bit first.
BUT I would definitely add it to water first and use it at watering time and not just pour coffee into the soil or you will go too far!

What Do Coffee Grounds Do
Coffee grounds act as a natural fertilizer for plants. They have often been used in composting and outdoor gardens due to the benefits they provide in keeping the soil healthy. They are acidic but do not change the pH levels of the soil when added.
Coffee grounds giveout nitrogen. It is important to plants since it is a major component ofchlorophyll. With the right amount of nitrogen, plants will grow and developbetter. There are three forms of soil Nitrogen:
NO3 negative ions do not bind with the soil due to the principle of like charges repel, instead they dissolve in soil water and precipitate as soluble salts.
Soil nitrogen is primarily made up of 95% Organic Nitrogen that comes from either plant or animal residue. Whereas plant nitrogen is common in inorganic forms such as Ammonium and Nitrate .
Plants requirelarge amounts of nitrogen, and even if nitrogen is readily available in theatmosphere, the whole process of absorption can take some time. For plants withrestricted root systems due to compaction, nitrogen deficiency will be evident.
In addition to nitrogen, coffee grounds also contain a good amount of phosphorus and potassium to keep your plant healthy.
What Plants Like Coffee Grounds
Acid loving plants like coffee grounds. You can also water them with cold black coffee occasionally alongside normal watering. Especially Jade Plants, Pothos, Philodendrons, African Violets, Christmas Cacti, Peace Lilies.

How To Use Coffee Grounds Properly
You need to use coffee grounds properly if you want to have optimal results with your plants. Coffee grounds, in fact, are very powerful and nutrient rich, and they need to be used with care.
To start with, remember that coffee grounds are green compost. This means that to give your plants a balanced diet, you need to add brown compost or carbon rich organic matter to your coffee grounds.
Cut up some dry leaves and mix in the coffee grounds before adding them to the soil. Any other carbon rich material will do, but dry leaves mix in very well with coffee grounds.
Only use a small amount of coffee grounds. So, no, the idea if growing plants directly in coffee grounds is not good gardening. Why? The same reason why they are so good: too much nitrogen. Let me explain.
Nitrogen is the nutrient plants need most. But if plants have too much nitrogen in the soil they do not develop their roots.
They have no reason to, because all the nitrogen they need is nearby. And this is a major problem.
When the nitrogen finishes, the plants dont have a well developed root system and they will suffer even die!
You can add coffee grounds to the surface of your soil. This is a good way to improve your soils nutritional levels and texture.
They will slowly mix in and they will leach the nutrients into the soil. Do not nix the coffee ground into the soil it is best to let the nutrients mix in the soil with rain and irrigation.

In smaller amounts, especially when mixed with dry materials, coffee grounds will give up their nitrogen. Used coffee grounds are actually nearly neutral in pH, so they shouldn’t cause concerns about their acidity. Be careful not to use too many coffee grounds or pile them up. The small particles can lock together, creating a water resistant barrier in your garden.
You can also make coffee ground “tea.” Add 2 cups of used coffee grounds to a 5-gallon bucket of water. Let the “tea” steep for a few hours or overnight. You can use this concoction as a liquid fertilizer for garden and container plants. It also makes a great foliar feed you can spray directly on the leaves and stems of your plants.

Tips For Adding Coffee Grounds To Your Plants
The fact that some plants go well with coffee grounds doesnt mean you should add them mindlessly. Youll want to follow some tips if you want to ensure you gain the desired results.
For coffee composts, you should perfectly adjust the mix ratio to avoid over-acidity. Add coffee grounds to the soil with a recommended ratio of 1:3 or 1:2. Otherwise, you can just use an online compost calculator.
Overuse can result in suppression of the plants roots, a dramatic decrease in soil bacteriasome of which are quite beneficialor trapping the soil worms. So, suiting the compost ratios and amount is pretty important.
When applying, scrub the compost into the soil or at least let it cover the topsoil with a layer of a minimum thickness of 1.5 inches. Also, take care to evenly distribute the compost to avoid aeration blockage in certain areas.
To use the coffee grounds as mulch, you can go through the same procedure but with a few tweaks. After covering the soil, all you have to do is to use wood chips, so they act as organic mulch layers. This will accelerate the soils germination. Such a process is often used while planting soya beans, cabbage, and sugar beet seeds.
Do Know The Acidity Of Your Plants Before Feeding Them Coffee
If you need a refresher on what makes something more acidic or alkaline, dont worry. If your plants are acidic, then their pH is 1 to about 6.
Anything from 8 to 14 is considered basic or alkaline, which is less acidic.
To make it more clear, gastric acid in your body has a pH of 1, lemon juice a pH of 2, and tomato juice a pH of 4. Milk, which is more neutral but still somewhat acidic, has a pH of 6. On the alkaline side, hand soap has a pH of 10 and bleach a pH of 12.
Black coffee is a 5 on the pH scale, so its not the most acidic substance, but it does contain much more acid than water. H2O is neutral.

Plants That Like Coffee Compost
Coffee compost is made from green materials and brown materials. The green materials, rich in nitrogen, refer to the coffee grounds. They take about 15% to 20% of the total compost volume.
These materials are mostly plant-based animal manures, fruit peels, or fresh grass.
Meanwhile, the brown materials, high in carbon, refer to newspapers, straws, or old dried leaves. This carbonic addition lowers the high acidic pitch and makes the compost suitable for many plants that dont accept high acidity levels.
