Bio-compost – Did You Know You Can Make Your Own Bio-composts From Your Kitchen Cabinet


The best time to fertilize your pot mixture or garden is before planting. I would suggest that before planning the basic crops to be planted or designing your vegetable garden, you need to build up a good microbial growth in your planting mixture.

We have already discussed in detail about the nutrients that you need to supplement the plant with for best growth of organic veggies. They are Nitrogen, Phosphorous, Potassium, Calcium and other micronutrients. So when you are going to look for organic waste to compost you would from now on look for what exactly is present in it.

For a thumb rule, just remember that anything that is originating from cowdung is rich in nitrogen. We would be discussing about the various other organic wastes you could successfully turn into fertilizer. You just need to remember this – the nutrients you get from the vegetable or fruit or any other food is what the plant is going to get too.

So with no further ado – let me go to the first source of plant nutrition which I have always promoted wherever I go – Banana Peel.

Bio-compost – Did You Know You Can Make Your Own Bio-composts From Your Kitchen Cabinet

  1. Banana Peel For Your Organic Veggies

Now, don’t look so surprised and I know your first thought Oh My God! I have been throwing away those banana peels everyday. Let bygones be bygones, begin today and here is how you are going to use those banana peels from today.

The very long procedure is – chop those banana peels, loosen the soil around the plant and bury the chopped peel, a little lower because you don’t want getting the fermenting smell of microbes working overtime.

Over, Just That?

Yes – it’s just that, after you consume a banana, chop the peel and bury in a pot or under a plant of your choice. Now take turns on every pot, give atleast a week before adding another peel to a pot.

What Do Banana Peels Do?

Bananas provide following nutrients to plants.

  1. Potassium – Potassium helps the plant in growing fast, resists pests and diseases, important for fruit development and also strengthens stems. Thus if you have fruiting veggies like tomato or stems like onions, make best use of your banana peels.
  2. Phosphorous – Helps in germination and viability of seeds, root and shoot growth, flowering, pollination and fruiting. Oops, isn’t that all that is required for some beautiful vegetable growth?
  3. Calcium – We call Calcium the ‘Trucker of all Minerals’ because calcium gives all the strength needed for the root and shoot tips to push and grow out.

And all this you could provide your veggies by not throwing away the waste banana peel.

So what next – Egg Shells!

  1. Egg Shells as Fertilizer

Egg Shells?  Why , How? Wait let me explain.

Egg shells, the ones you throw after you make the bulls eye or peel off from the hard boiled eggs provide nitrogen, phosphorous and calcium to the plant.

Nitrogen helps in making your plants green and healthy. Others you already know – right?

How To Use Egg Shells

Powder the egg shells and directly sprinkle around your growing veggies. This is helpful particularly in the rainy season, because calcium easily gets washed away.

Note- Personally I would prefer boiling the egg shells, drying and then grinding them to a soft powder. This you can store for any period of time without having the need to be concerned about them getting contaminated.

  1. Coffee and Tea Remnants as Fertilizer

So what do you do after you infuse tea or coffee, throw the remnants away?

I know that is what exactly everyone else does too. So here is what you need to do, especially if you have rose plants and tomatoes or any kind of berries. Dry the remnants and sprinkle around the plant.

You would get some great berries and the flowering is boosted.

  1. Epsom Salt

Epsom salt gives good amount of magnesium and sulphur to plants, these micronutrients are always deficient to the plants. So for your pot all you need to do is, add a teaspoon of Epsom salt to 1 litre of water. Put it in a spray bottle and spray on your plant.

  1. Themor Karaisal or Cocomilk

This is something you cannot uses straight away. When you have some sour buttermilk, add equal quantity of coconut milk and tender coconut water. The ratio is 1:1:1, and let this to ferment in an earthern pot for a week. You can then uses this mixture as biofertilizer after diluting with water in the ratio of 1:10 and spray.

I always recommend this as a soil treatment or soil preparation mixture for raising the good bacteria before panting.

  1. Amritha Karaisal or Amrith

This is a mixure of cowdung, cow urine, jaggery and water, needs to be fermented for 24 hours and then diluted. This works like Amrith on the soil. I know it is difficult for you to get this done at your place and hence Simple Indian Mom has come up with ready made Amrith for you. You can contact me to get them.

  2. I cant help feeling guilty, Menaka. I consume all these things and my heart breaks to throw it all away. I cleared my verandah of plants because of the pigeon menace. Now we’ve covered it with a net, but the plants are not back. Loved the post. Must seriously think of pots now.
    (Where is the banner?)

  3. Organic manure is the best! I used to have a little garden back when I was at home and we only used bio compost and the results were pretty good. Thanks for such an informative post.

  4. I did not know that it was this simple to create compost. I actually have been wasting so many peels, eggs shells and tea leaves! Thanks for the valuable tips.

  5. Great post! We bought a big composter years ago, but I never got the hang of what to put in and stopped using it. I’m going to give it another go 🙂

  6. Once again a very interesting and informative article. What a pity my balcony is only 3 ‘ x 5 ‘ and barely holds my wash stand

  7. Thanks for an informative and insightful post, Menaka. I must use banana peels, egg shells and tea for a few plants that I have in my balcony!

  8. This is such a useful tip.
    I usually waste the banana and butter milk .
    Let me try these on my plants .
    Very informative, good going

  9. The waste water from RO has no much nutrients in them, however, when we use other organic fetilizers there is no problem in using it to irrigate the plants.

  10. Yes! I’ve seen about bananas and egg shells in a few videos and they work wonders to the plant!

    I too am going to inculcate this in the plants in my garden ask the gardener to do 😛

    Thanks for sharing the information!

  11. I use my kitchen waste to make bio fertiliser but honestly I don’t segregate the coffee grinds from the eggshells. Doing that would be a full time job. So I put it all together and use it.

  12. Good tips. My mausi used to make such compost at home for her kitchen garden.
    It is recommended to use the waste water from RO for watering plants. Do you advise it?
