How To Regrow Crops From Kitchen Leftovers

When people think of farming or growing crops, they mostly imagine it on a large scale or think about raising capital to buy seeds to plant. They rarely consider growing crops from the kitchen leftovers.

Pause for a minute and reflect back to the random moments where you would throw out the water containing the seeds of pepper or tomatoes and they start sprouting up from that same spot. As little as they would bring up, these plants/produce do really come in handy.

Each year, 1.6 billion tons of food worth about $1.2 trillion are lost or go to waste. That is, unbelievably, one-third of the total amount of food produced globally (Bcg 2018). Food wastage is a very important issue globally and we all have a responsibility to put an end to it every way we can.

This article will highlight a list of the crops that can be grown from kitchen leftovers and how you can easily grow them yourself.

This is the most commonly grown fruit made from scraps or leftovers. Instead of unconsciously throwing away the seeds from tomatoes just anywhere, be intentional this time. Find a small space with fertile soil or get the soil in a bowl, place in a place with good sunlight, pour the seeds on it and watch the plant begin to sprout up. After 3 or 4 days, you will notice the roots beginning to appear along with new leaves. Be sure to water your plant daily.


This just requires one clove of ginger. Find one with the roots and plant it facing down in a pot with soil. Place pot in a place with direct access to sunlight at all times.

If you prefer to buy the whole pineapple fruit and do the peeling and cutting yourself at home, then this is for you (and anyone else planning to try). All you need to grow your own pineapple is the head/top of the fruit. There are two methods of planting.

  1. You can plant directly to the ground or in a pot with soil, and place in a spot with good sunlight. Take time to water the plant regularly to keep the soil moist.
  2. You can also plant first in a container with water. For this, hold the pineapple crown with small sticks above the water to prevent it from being submerged. Change the water regularly to avoid molds. After 6- 8 weeks, the roots would begin to appear and then you can transfer from the water to a pot with light soil mix. It is quite easy to plant and just requires patience as pineapple takes a couple of years or more to fully form.
