By chopping the bottom of an onion bulb off and planting it into soil, you can grow your own onions from cuttings. You can grow an onion from an onion bottom in 90 minutes or less if you have a bit of knowledge, patience, and lots of water. The first step is to cut off the top of the onion and plant it in a pot of soil.
You can use any type of potting soil you like, but I like to use a mix of peat moss and vermiculite. This will help keep the soil moist and prevent the root system from drying out. If you don’t have a soil mix, I recommend using a mixture of 1/2 cup of sand and 2 cups of perlite, which is a fine-grained clay that is easy to work with.
I also recommend adding a few drops of liquid dishwashing detergent to the mix to keep it from sticking to your hands while you’re working with it. The soil should be moist but not soggy, so you’ll want to make sure it’s not too wet or too dry before you start cutting.
