FAQs
Long Green Onion is generally easy to care for, though some plant parents report facing challenges with growing it. Check out the reviews down below to read more about their experiences!
Water Needs
Long Green Onion prefers for the soil to dry out between waterings and should be watered regularly. Use our water calculator to personalize watering recommendations to your environment or download Greg for more advanced recommendations for all of your plants.
Sunlight Needs
Long Green Onion requires abundant, bright and direct light. Place it less than one foot from a window to ensure it receives enough light to survive 💪. Select your region to see how the current weather in your area affects the placement in your home 🏡.
Soil
Long Green Onion does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Fertilizer
Long Green Onion should be repotted after it doubles in size or once a year, whichever comes first. Fresh potting soil has all the nutrients your plant needs, so as long as it’s refreshed yearly, you shouldn’t need to use fertilizer. Remember, plants get their energy from sunlight, not fertilizer!
Growth Pattern
Long Green Onion grows vertically and new growth will emerge from the top of the plant.

I started these from the ends of green onions I got at the grocery store. All I did was stick them in some dirt and they started sprouting! Really easy to repot them.
