What Makes Banana Peels an Excellent DIY Plant Fertilizer?

Many health experts encourage people to consume fruits and vegetables with their skins on because the real nutritional goodness is usually the most concentrated in the outer peels.

For instance, while apples are known for helping gut health, the most soluble fiber is usually only in their yellow-red skins.

However, although you cannot consume a banana’s peel to benefit from all its nutritional wonders, you can still make the most of these nutrients by feeding them to your growing, sick, unhealthy, and weak plants.

Banana Peel Fertilizer Benefits

  • A banana peel contains some of the most vital nutrients and minerals that can impact a plant’s health and improve its growth rate.
  • When you place a banana peel on the plant’s potting soil, it slowly decomposes, releasing all its packed nutrients into the soil.
  • As you water the potting mix, those rich nutrients drip deeper into the soil until they reach the plant’s roots.

DIY Banana Peel Nutrient Solution For Plants

1. Prepare Homemade Slow-Releasing Liquid Fertilizer

Since banana peels can take some time to decompose into the soil, the best way to unleash their nutritional magic is by turning them into a slow-releasing liquid fertilizer.

Finally, strain the banana peel and water mixture and collect the liquid fertilizer into a spray bottle. Spray the banana fertilizer onto the plant’s potting soil and use a garden shovel to mix it in.

To make the fertilizer even more effective, you can crush in a few eggshells and add a small amount of Epsom salt.
