Why Grow Spring Onions from Scraps?

Step-by-Step Guide to Growing Spring Onions from Scraps

What You’ll Need

Spring onions (store-bought or leftover)
Water or potting soil
A glass or container (if using water)
Sunny windowsill or garden spot

Step 1: Prepare Your Scraps

Start by cutting the spring onions about 1-2 inches from the base. Make sure you have some roots attached; this is crucial for regrowth. You can use green onion scraps from your meals or purchase a bunch specifically for regrowing.

Step 2: Choose Your Growth Method

You can grow spring onions either in water or soil. Both methods are effective, so choose what works best for you:

Water Method: Place the white bulb ends in a glass of water, ensuring the roots are submerged while the green tops remain above water.
Soil Method: Plant the bulb ends directly into a pot filled with potting soil, leaving the green tops exposed.

Step 3: Provide Proper Care

For both methods, keep your spring onions in a sunny spot. If you’re using water, change it every few days to keep it fresh. If using soil, water lightly, ensuring the soil stays moist but not soggy.

Step 4: Watch Them Grow

Within a week, you should start to see new green shoots emerging. As they grow, they’ll become taller and more vibrant. You can trim the green tops as needed for cooking, allowing the bulbs to continue growing.

Step 5: Harvesting

Once your spring onions reach about 6-8 inches tall, they are ready to be harvested. Simply cut off what you need above the white bulb, and they will continue to grow more shoots. You can enjoy fresh spring onions over several weeks!
