Materials to make your Onion Tree.
- Onion sprouts (you can experiment with seeds).
- Plastic bottle (The size is up to you).
The procedure is very simple.
1. We take the onion sprouts (small bulbs) or onions that we have on hand and remove the peel. We leave them overnight soaking in water. Before this it is necessary to prepare any plastic bottle.
2. To do this, we cut the neck of the bottle, then we make holes around our bottle.
3. Next, we take the earth and we create layers of onion and earth.
4. That's it.
