DIY organic fertilizers from ordinary things

Organic fertilizer is great for your plants. Using organic fertilizer can help ensure a healthy environment for you and your plants.  Unfortunately, it can be expensive.  The solution is to use one or all of these DIY organic fertilizers from ordinary things.

DIY organic fertilizers from ordinary things

There are lots of things that you use in your everyday life that will make great organic fertilizer.

Tea Bags as fertilizers

So many people love to start their day with a nice cup of tea.  So teabags would be a great DIY fertilizer.  But what do you do with the tea bags?

DIY organic fertilizers from ordinary things

Well, there are a few ways that your old tea bags can benefit the garden.

Tea has a great balance of micronutrients that can benefit most plants.

Most importantly, tea contains Tannic Acid, which has been shown to immobilize some metals like aluminum that find their way into soil and water.  This will play a major part in keeping the roots safe from these metals.

The PH of tea is low, in the 5.4 – 5.6 range.  This will help balance your soil if it is higher than the 7.0 range that most plants like.

To use as organic fertilizer.

Sprinkle used tea leaves around your plant’s soil, staying a couple of inches from the base.  Do this once a month or on your regular fertilizing schedule.


Put your used tea bags into your compost bin.  They will add great micronutrients.

Please note that some tea bags contain a small amount of plastic. Check with the brand you like to find out if they do.  Even if they use plastic, you can still empty the tea bag’s contents into the compost pile the discarded the bag.


Cats hate tea! So sprinkling tea around your plants can help keep gas from invading your planters or garden.


DIY organic fertilizers from ordinary things: coffee grinds

I love coffee!  I use an empty coffee can to store my used grounds.  It usually takes me less than a week to fill the can up.  When the can is full I dump it into my compost bin.  This may be the easiest of the DIY organic fertilizers for ordinary things.

Coffee is considered a “green” in your compost bin because it is high in nitrogen, almost 2%.  Just like tea, coffee contains lots of needed micronutrients like magnesium, calcium, and potassium.

Brewed coffee grounds are typical PH neutral, so they will not affect the PH in your soil.  Un brewed coffee is acidic, so only use un brewed coffee on acid-loving plants.

coffee as fertilizer

To use as fertilizers.

You can add coffee sprinkled directly around your plants, and beware that too much or too thick a layer directly on the soil can slow any water getting to your plants.  So for direct applying, over mulch or other dryer materials works best.


Add coffee to your compost pile.  Worms love coffee!  So, in addition to the nutrients, you are adding, you are making your worms very happy!


Worms love coffee, but pests like snails and slugs don’t, so coffee can control naturally pests.

Eggshells as organic fertilizers

Eggs shells are a wonderful addition to any organic garden, and these shells are certainly an ordinary thing that makes a great organic fertilizer.  But you have to use eggshells, right, or you will miss out on all that nutrition.

The shell is typically very high in calcium carbonate, about 95%, with a lot of phosphorus and magnesium, about 3% of each.  Shells also contain trace elements like iron and copper.

The problem can come into play when you discover that the eggshell doesn’t break down in the garden or the compost bin as fast as most other things.  Because of this, adding eggshells whole or crushed to your compost bin or garden does not allow the release of all that good stuff, and you have to release the nutrients from the shell in another way.

The only easy way to get the nutrients from the shell to your garden is to dry and gird them up.  This is not the easiest DIY organic fertilizer for ordinary things, but it is great for your plants.  It is also the best way not to waste the nutrients in eggshells.

How to use ground up eggshells as fertilizers

It is easy to make eggshell powder.

  1. Rinse the shells with water,
  2. place them in a baking pan or cookie sheet
  3. place them in an oven at no higher than 300 degrees.  *180 degrees in just a few seconds will kill any salmonella.
  4. when they are dried, take them out to cool
  5. grid them in a coffee grinder or food processor

The eggshell-powered will store well in a mason jar or add it directly to your compost pile or garden.

Bonus…or maybe not…

Lots of people believe that you can put crushed up eggshells around your plants for two benefits :

1. release nutrients …we now know that’s not true.

2. the sharp shell pieces will stop slugs and snails from getting to your plants…there is a lot of great research that disproves that theory.  So the bottom line is eggshell is a great fertilizer, but only if you take a little time to make them plant-friendly.

DIY organic fertilizers from ordinary Bananas

Bananas are another ordinary thing that can make a great organic fertilizer.

The banana peel contains a lot of potassium, a vital nutrient to promote health stems, flowers, and fruit.  They also contain a lot of calcium which is important to help prevent end rot in tomatoes.

To use as organic fertilizers

you can throw your peels into your compost pile


you can put the peels into a container of water for about a week.  Then use the water as part of your normal watering process


My favorite….put the peels in the blender with enough water to cover then liquify them.  Use the liquid banana peels as a quick boost to your flowering fruits and vegetables.

Ordinary Aquarium Water as an Organic fertilizers

Using aquarium water is one of the best and easiest ways to keep your plants happy.  This is an easy DIY organic fertilizer for ordinary things if you have a fish tank.

I love aquaponics.  You don’t need a whole aquaponics system to enjoy the benefits of science.  You need a fish tank….and fish!

Fish poop water has most of the nutrients that any plant needs to be happy.  The water is very high in nitrogen, so your green leafy plants will like it best.  This high level of nitrogen is the reason why you often see algae growing on tank walls.

To use fish water,

simply water your plants with the old fish water when you change your tank water.


add a cup or so of fish water to your plant water every week,

or hand your plants over the top of the tank allowing the roots to be submerged.

It is just that easy!
