For those who appreciate fresh, organic produce, growing onions and garlic at home is a satisfying endeavor. Surprisingly, you can repurpose discarded polystyrene packages for this purpose.
Start by saving polystyrene boxes, especially those with lids. Mark measurements using plastic caps and cut out the polystyrene using a cutter. With the halves separated, trim the roots of small onions and cut the tips. Repeat the process with garlic.
Place the cut part of the roots into the holes made in the polystyrene and use the other half as a water saucer. Within a day, you’ll observe new roots and green shoots emerging from the onions and garlic. After about 5 days, when the roots have grown, transfer them to a larger polystyrene box with drainage holes and soil.
