Natural Fertilizer Recipe Disclaimer

The recipes shared here are what we use in our own gardens.  One of the drawbacks of using homemade fertilizers is that the NPK ratios are not accurate.  You can use these for more of a long term way of building soil. They are safe to use in moderate amounts throughout the growing seasons.  You will still need to use other slow release fertilizers such as bone meal, blood meal, greensand, etc as they are much easier to dial in the correct amounts of NPK.  We also use other water soluble fertilizers such as fish fertilizer and other organic means.  Now that we got that out of the way, let’s see what recipes you garden superheroes can make.  We provided the average NPK ratios with each recipe as a guide.

Homemade Fertilizer Recipe #1Homemade Fertilizer

  • 1 Cup Coffee Grounds (2- 0.5- 0.5)-primary usage is for Nitrogen.
  • 20 Banana Peels (0-3-42)- 1 peel has a ton of Potassium
  • 20 Eggshells (1.2-0.4-.1) – Great source of calcium
  • 0.5 lbs Epsom Salts – Used as a balancer that has magnesium and sulfur

Sprinkle about 2-3 tablespoons around each plant every few weeks.

Instructions & Prep notes for this recipe

You can source coffee grounds from your own spent coffee grains or from Starbucks.  I would not recommend using unused coffee grounds as it can be acid forming.  We like to source our coffee grounds from star bucks in large amounts.  You can dump bags of it into your compost piles and also use some of the grounds to make our homemade fertilizer.  It is ideal to save about 20 banana peels to have enough.   You can store the peels in the freezer to keep them from spoiling until you are ready to process the. The eggshells are rinsed with water and also stored in a bag in the freezer.

You want to make sure that you dry the banana peels, coffee grounds, and eggshells in your oven at about 150 degrees.  You are not cooking them, but rather drying up the peels, grains and shells of the water content.  This dried natural fertilizer will keep much longer once the water content has been removed.  The banana peels will take the longest to dry such as 5-6 hours.  You want them to be almost brittle or leathery like so that they  can become a powder when you blend them.  The optimal way would be to use a food dehydrator as you may know some older ovens may not go as low as 140 degrees.

Next, you will need to use a coffee grinder or blender to pulverize all the ingredients to have a powder.  It is ideal to store this powder in a tupperware or some other airtight container.  You can sprinkle this homemade fertilizer directly around your plants in the garden.  Another option is to mix this up with compost tea to use as a water soluble fertilizer.
