Used coffee Grounds are not worthless; they contain potassium, phosphoric acid, and nitrogen. All of these are excellent for your plants, particularly those that are acidic, such as many fruit trees, tomatoes, azaleas, roses, camellias, blueberries, and evergreens.
The coffee grounds should be allowed to dry before being used. Lightly distribute them over your plants to begin. When they are damp, avoid spreading them widely since wet clusters might grow mold.

3. EGGSHELLS

Eggshells should be cleaned before being used, then crushed and ground into a powder. Eggshells contain calcium, phosphoric acid, and nitrogen, making them useful fertilizers. In addition to aiding in the prevention of blossom end rot, the calcium in the shells is crucial for cell growth and production.
You can use the 93% calcium carbonate found in eggshells to make your own potting mix for beautiful and healthy fruits. Much calcium is taken out of the soil, just like when your plants grow. This is a great technique to recycle eggshells and sprinkle them over your garden soil because your soil needs additional calcium.
4- CORN GLUTEN MEAL

Corn gluten meal is a byproduct of the water milling process of corn. It can be applied as a pre-emergent organic herbicide. You can classify it as fertilizer because it includes 10% nitrogen.
Using this fertilizer is easy; just apply a thin coating of corn gluten meal to your soil and scratch. This will maximize the benefits of nitrogen without harming your plants.
5. GREEN TEA

Green tea is beneficial to your health, but once you use it, the leaves or bags are worthless. Every four weeks, you can make a weak green tea solution to use on your plants. Two gallons of water can be made with just one tea bag.
6- POWDERED MILK

Add or mix powder milk in the soil before sowing. As milk is in powder form, therefore it is ready for the use of your plants.
Aquarium Water When cleaning your aquarium, use the water directly from the tank to water your plants. Fish excrement is an excellent source of fertilizer for plants. Do not use water from a saltwater tank; only use fresh water.
in certain regions. Because the ashes are alkaline, they might make the soil more alkaline.
7. MATCHES

It may surprise you to learn that old-fashioned, easy-strike matches are an excellent source of magnesium and make good fertilizer. How these matches are used as fertilizer is the question that comes to mind.
You can soak matches in water for later use, or you can just put the entire match in the hole with the plant. When this liquid is ready to be added to the soil of the plants, it will become a good supply of magnesium.
8. FEED FOR HORSES

Molasses is a fantastic element that makes it a superb fertilizer. One easy way to utilize it as a soil amendment is to sprinkle it on top of the soil. Another method is to dissolve it in water and combine it with another organic fertilizer. Apply this mixture as a soil drench now.
9. WATER IN AQUARIUM

Don’t waste any water that has been removed from the aquarium when you begin cleaning it. Because fish waste is so beneficial and makes an excellent plant fertilizer, you can use this water for your plants.
10. Bananas

Not only are bananas tasty and good for you, but they are also good for many plants. When planting roses, bury a banana (or simply the peel) in the hole alongside the rose. As the rose grows, bury bananas or peels from them into the top layer of the soil. Both of these ways will offer the much-needed potassium that plants need for optimum growth.
11. Blackstrap Molasses

Blackstrap molasses is a great way to get a variety of nutrients that plants need. Carbon, iron, sulfur, potassium, calcium, manganese, copper, and magnesium are some of them. This is a great natural fertilizer since it feeds good bacteria that maintain the health of the soil and plants.
Blackstrap molasses can be combined with another all-purpose fertilizer to be used as fertilizer. One cup each of alfalfa meal and Epsom salts is a nice combo to use. After dissolving this mixture in four liters of water, add one tablespoon of blackstrap molasses on top.
Or just combine compost tea with blackstrap molasses. Wait until the compost tea has steeped before doing this.
12. WOOD ASH (found in your fire pit or fireplace)

Calcium carbonate and potassium are beneficial for plant growth. Wood ash can be used for this; all you need to do is sprinkle the nutrient-dense powder onto your soil to replenish the calcium and potassium.
Charcoal is bad for your plants; therefore, please don’t use it on lighter fluids. The greatest choice for producing wood ash for plants is hardwood. It is crucial to understand that plants that prefer acid do not do well with ashes. Because ashes are alkaline, they can make the soil more alkaline.
13. Gelatin

Your garden soil needs fertilizer if it is really poor and weak. You can obtain a good amount of nitrogen from gelatin powder as well as from fertilizers.
Just one package of gelatin should be dissolved in one cup of boiling water; three cups of cold water should then be added. Pour this solution straight over the soil surrounding your plants once a month.
14. MANURE

Cow manure is an excellent source of all-important healthful nutrients. It is a common organic fertilizer. If you need a quick boost for your growing plants, you can also use poultry manure instead of cow manure.
Mostly poultry manure is given to the soil after harvest and before a second planting; it works very rapidly on the soil for organic growing.
15. WEEDS AND GRASS CLIPPINGS
