Cultivate onions in a greenhouse with recycled plastic bottles
Growing onions in a greenhouse can be an excellent way to produce fresh and tasty vegetables throughout the year. In addition, using recycled plastic bottles, you can help preserve the environment. Rooted in sand, onions can grow quickly and in a healthy way.
Materials required:
- Recycled plastic bottles
- Onions
- Sand
- Water
- Scissor
Steps to grow onions in a greenhouse with recycled plastic bottles:
1. Cut the top of the plastic bottles, making sure to keep the lower part wider. Drill small holes in the bottom to allow water to drain.
2. Fill the bottles with sand on a height of about 10 cm. Moisten the sand slightly to give it an ideal consistency for onion growth.
3. Plant the onions in the sand, spacing them about 10-15 cm. Make sure the bulbs are inserted slightly into the sand, while allowing the leaves to pass on the surface.
4. Water the onions regularly to keep the sand moist, but not wet. Roots of onions will quickly grow in sand for water and nutrients.
5. Place the bottles in a greenhouse or place well exposed to sunlight. Onions need at least 6 hours of sun a day to develop properly.
6. Monitor the growth of onions and continue to water them regularly. You can also add natural fertilizer to promote stronger growth.
7. Harvest your onions once they have reached a satisfactory size. You can enjoy fresh and ecologically cultivated onions.
