Introduction
Growing onions is a satisfying experience that provides you with fresh, flavorful produce all year round. If you live in an apartment or have limited space, growing onions in water is an excellent option. It is an easy and cost-effective way to grow onions without needing a garden or soil. In this guide, we will explore everything you need to know about growing onions in water, from selecting the right onion to harvest. So let’s get started!
Choosing the Right Onion
The first step to growing onions in water is choosing the right variety. Select an onion with a small to medium-size bulb, such as scallions or green onions. These onions thrive in water and grow quickly, producing green tops in just a few weeks.
Preparing the Onion
Once you have selected the onion, it is time to prepare it for growth. Trim the roots to about an inch in length, and cut the onion about an inch above the root. Place the onion in a jar or glass filled with water, with the root end submerged in the water.
Location
When growing onions in water, it is essential to choose the right location. Place the jar in a sunny window or near a bright light source. Onions require at least six hours of direct sunlight each day to grow correctly.
Watering
Onions grown in water require a consistent water supply. Change the water every few days to ensure it is clean and fresh, and the roots have enough oxygen to grow correctly.
Fertilizing
While onions in water do not require fertilizer, you can add a liquid fertilizer to the water to promote growth. Add the fertilizer according to the package instructions and avoid adding too much, as this can cause the onion to rot.
Harvesting
Harvesting onions grown in water is easy. Simply cut the desired amount of green tops above the white bulb and continue to grow the onion in the water. If you prefer to harvest the entire onion bulb, allow the bulb to grow to the desired size before removing it from the water.
