So, I immerse the chopped-edge of onion in small amount of water. Within couple of hours or maximum a day, I see fresh white roots emerging from the sides. I then plant in some soil. The second picture shows the green onion plants growing from such chopped off edges. Garlic plant growing from store-bought organic garlic clove; one of the potato in the potato-bag was budding. So, I put it in the soil, and couple of days later a potato plant is growing.
But, my prized possessions are the leeks that I am growing from chopped-off edges. While cooking leeks, we all throw away the edge which has the roots. Instead of throwing them away, I put them in the soil, and within couple of days a plant emerges. And, they grow fast!!! This whole plant has grown from that tiny edge within two weeks. Soon, I have to transplant them outside or in bigger containers and need to start putting soil around it to blanch the lower portion.
So far, I am growing onion, leek, garlic and potato from store-bought items. Now, I hear you. You will tell me that the store-bought potato might have some disease and that will affect my garden. I have not had such bad luck so far (touch-wood). I also believe that if you take care of soil, respect nature, love and caress and talk to your plants and don't use chemicals, no such accidents will happen. That has been my experience so far. But, who knows? I might be wrong as I am still a novice gardener. Re-using such store bought items and throw-away parts not only helps in sustainability but also in saving :-). Sweet potato slips can also be grown in similar ways - by hanging a sweet potato in water -- but no luck so far. Grrrrrrrrrrr.........
Do you have any ideas/advice/suggestions for growing food from store-bought items?
