Top 9 Kitchen Ingredients to Fertilize Your Plants


You probably know how important it is to put the proper nutrients in your plants to give them a fighting chance.

If you’re looking for ways to feed your plants without spending too much money, check out this list of top kitchen ingredients that are excellent fertilizers for plants.

Any of these can help your plants grow and thrive even if they aren’t directly from a plant. You don’t need many ingredients to keep your plants happy and healthy.

You don’t even have to buy any of them – you can use natural household items instead! Many of these also are great for human health, so there are two benefits to one action.

Seaweed Tea

Seaweed Tea is a fantastic all-natural fertilizer for your garden.

This material is high in nutrients and minerals, which are necessary for plant growth, and it also aids in the retention of moisture in the soil.

As a result, it is appropriate for drought-prone locations.

Furthermore, Seaweed Tea is efficient in controlling weeds and pests, making it a fantastic organic gardening ingredient.

Coffee Grounds are an Excellent Natural Fertilizer

You may have heard that coffee grounds make wonderful garden fertilizer, but that’s not all!

Coffee grounds are a good repellant to slugs, slugs, ants, and even cats, in addition to raising the acidity of too alkaline soils and enriching low-nitrogen soils.

To use coffee grounds in the garden, simply place a small quantity at the base of your plant or mix it (up to 15% of the total volume) with the soil in your flowerpot or planter.

And did you know that if you have rhododendrons, roses, magnolias, or hydrangeas in your garden, a little coffee grounds can change their color from pink to blue-purple?

Just give it a shot; the results will be astounding!


As you can see, beans are not just crunchy and delicious. They are also great for plants. If your soil is nutrient-poor, beans are a great way to introduce some nutrients into the ground.

They can also be helpful if you find that pests are a problem since they create a natural insecticide. You can also use beans as a mulch for your plants to help retain moisture and keep the soil warm.

If you have plants that need nitrogen, beans can help with that, too. Beans are an excellent “green manure” crop, meaning they are plants that are grown specifically to enrich the soil.

You can add them to your compost pile or let them decompose in your garden. Beans benefit from legume plants like beans, alfalfa, or clover.


Rice is an excellent food for humans, but it is also great for plants. Like beans, rice can be used as a soil amendment to help plants grow big and strong by providing nutrients and improving the soil.

If you want to use rice as a fertilizer, you can put it in a blender or food processor to grind it up into a fine powder.

If your plants are struggling to grow in poor soil, you can add rice to the area around them to help them grow more healthfully. Rice can also be mixed with water and used as a liquid fertilizer.

You can also use rice hulls, which are the outer shells of rice after the grains have been removed, as a mulch in your garden.

Organic Banana Fertilizer from Peel

Potassium, phosphorus, and calcium should be present in suitable numbers in practically all of your crops and vegetable gardens, and guess where you can readily get them?

Of course, on a banana skin!

There are two methods for making natural fertilizer from banana peels:

You can bury the banana peel by cutting it into little pieces and burying it near your plantation.

When they rot, they release all of the nutrients they contain into the earth.

You may generate liquid fertilizer from banana peels by soaking them in a large container of water for 3 to 4 days before watering your plants.

For a 5L container of water, provide between 5 and 10 banana peels.

Boiling water with No Salt

Recycling is commonplace in the kitchen.

Boiling water is an appealing feature for nourishing green plants.

Vegetable water or eggs are the only valuable sources of vitamins and minerals that are recovered after cooking if they are not salted.

The gravy is poured at the plant’s base when it has cooled.

The same is true for potato water, which naturally kills weeds when still hot.

As a result, take care to just target undesirable shoots.


Eggshells are high in minerals such as calcium, magnesium, and potassium.

Crush the shells gently and place the fragments around your indoor plants.

The eggshell fragments will continuously add nutrients to the soil.

Epsom Salt

Brine with Epsom salt, which is high in sulfur and magnesium, is perfect for rose or tomato plants, and this natural fertilizer will also make plants that have grown in poor soil happy.

To use this organic fertilizer in your home garden, simply combine 4 L of water and one tablespoon of Epsom salt before watering your plants.

Generally, the results are satisfactory!

Red Onion Skin

Red onions are commonly used in cooking to add flavor to foods.

Onion peels, which are generally tossed, are actually beneficial to plants.

Calcium, potassium, and magnesium are all found in onion peel.

The content has the ability to fertilize plants, reinforce stems, and boost disease resistance.

It is simply used by soaking the onion skin overnight and then sprinkling the onion solution on the plants.


These top kitchen ingredients make great fertilizers for your plants, but there are many other options out there, too.

If you want to use a kitchen item to feed your plants, ensure it’s organic.

Using ingredients from your kitchen is a great way to save money while still providing your indoor plants with the nutrients they need to thrive.
