A cup of tea and two bananas.
Bananas have minerals that can promote the growth and development of plants.

Banana Fertilizer

A whole banana, including its peel, is rich in potassium. This mineral is great at promoting blooming in plants. In addition, this mineral is readily absorbed by plants once you add it to the soil.

In addition, bananas also have a high content of phosphorus so banana peels also strengthen your plants and make the photosynthesis process more efficient. As you can see, it’s completely eco-friendly.

How to Make It

  • First, cube the banana peel and place it in a pot.
  • Next, add water to it – just enough to cover it.
  • Then, place it on the stove and boil for about 15 minutes.
  • Let it cool down and then strain it.
  • Dilute it with two more equal parts of water.
  • Finally, apply it to your plants.

In addition, you can also allow the banana peels to dry and then pulverize them to use as a powder fertilizer.

Nettle Slurry Made with All-Natural Ingredients

A slurry is a fermented bio-stimulant extract that boosts plant growth and strength and reinforces its natural defenses. Nettle slurry, in particular, adds a lot of nutrients to crops. It contributes all of the nitrogen that plants need for proper growth. Besides, it’s also great as fungicide and pesticide.

How to Make It

  • First, place about two pounds of nettles in a container. Don’t include the roots.
  • Then, cut it in small pieces and let it steep for a couple of hours in about three gallons of non-chlorinated water.
  • Finally, strain the water and add it to your plants.

Wood Ash

A bunch of charred paper.
Wood ashes are also great as plant food. However, they must be from untreated wood and without chemicals. As an added benefit, they’ll keep pests at bay.

The use of wood ash as an all-natural fertilizer promotes maturity in plants, especially fruit trees. It’s also a great pesticide. However, it’s not recommended for increasing the pH of the soil.

Furthermore, keep in mind that you have to select ash from untreated, quality wood. Make sure it doesn’t contain heavy materials, chemicals or varnishes.

How to Make It

  • In this case, you simply have to dilute the ash in your irrigation system and apply it.
  • In addition, you can also place a small layer of ash around the stems (without touching them) and bury them in the ground.

Applying some of these natural fertilizers will help you avoid the use of chemical products, which are highly toxic and dangerous in many other ways. Not only that, but they’re often absorbed by the crops.
