These step-by-step instructions show you how to grow ginger root from the grocery store. By propagating the root you can grow a new plant that will also produce more ginger rhizomes (the part we eat).
You can also grow your own avocado plant from seed and grow mango using these instructions.
Growing Ginger
Learn how to use ginger root from the grocery store to grow ginger plants. Grow them as houseplants or keep them outdoors in the summer in cold climates. As the rhizomes grow and spread, you will have ginger to harvest.

What is Ginger?
Ginger (Zingiber officinale) is a tropical herbaceous perennial. If you live in a cold climate, this means you can grow it as a houseplant indoors year-round and keep it outside in the summer months, if you like.
That ginger root that you buy at the grocery store is all you need to start your own ginger houseplant.
It’s Really a Rhizome
To be more accurate, what we call ginger root is really a rhizome. Roots grow from the rhizome, but we don’t eat those. But, the common term is ginger root, so we’ll roll with it.
Ginger is used as a spice for cooking, smoothies, and some baking like ginger snaps. You might use dried ginger, ginger powder, or fresh, chopped or grated ginger.
For many years ginger was regarded as a good remedy for nausea (ginger ale), but research has not confirmed this.
The Rhizome Grows the Plant
The rhizome not only provides the spice but that’s the part we root and grow into a new plant.
As it grows, more rhizomes will form, giving you new ginger to harvest.
Some ginger growing methods soak the root overnight and then plant it. And this can definitely work.
I prefer to use the method shown below because it guarantees I am planting a viable rhizome and won’t be disappointed.
I’ll show you how to select a good candidate for rooting, how to make it sprout, and how to continue growing it as a houseplant.
And I’ve answered frequently asked questions about growing ginger here.
How to Grow Ginger Root
1 Choose Living Ginger Root
Tip: Use Organically-Grown Ginger
If you’re planning to eat your ginger, start it from an organically-grown ginger you know is food-safe.
I use ginger from the grocery store, but you can also purchase it from some plant nurseries specifically for this purpose.
Look for pieces that are firm, healthy-looking (not dry or shriveled), show no signs of damage, and have ‘eyes’ (see the circled example in the photo, above). These are the little nubs like the ones on potatoes that will grow roots under the right conditions.
You might also find a piece of ginger that is sprouting in the store: that works fine!
Start with 2 or 3 rhizomes if you want to be sure to get at least one plant.
If you want to go big, root 3-6 pieces of ginger and plant them all in one pot.
2Sprout Your Ginger Root
The arrows show nubs that will grow roots and shoots.
- Wash and dry the ginger root (rhizome) and take a few photos of it.
- Wrap it in damp (not soaking wet) cloth or paper towels and place in a plastic bag.

It is possible that your ginger root may have been treated with a growth inhibitor, but the presence of emerging buds is a good sign it will sprout.
- Stash bag in your kitchen cabinet. A temperature around 70°F (21°C) is fine. The combination of moisture and warmth will cause it to sprout.
- Set an alert on your phone to check it every three days.
3Monitor Growth
Take photos! At first it will be hard to tell the nubs are growing but you can confirm it by comparing photos along the way.
After two weeks, the roots and shoots are starting to grow.
- After approximately 7-10 days, you should definitely start seeing growth from the eyes/nubs.
- Return the ginger to the damp towel in the plastic bag until the shoots and roots are a few inches long.
Here’s mine after 4 weeks:
Growth after 4 weeks in damp paper towel and bag.
Be careful each time you unwrap and rewrap the ginger to avoid breaking any new roots or shoots.
Here it is after 5 weeks:
Growth after 5 weeks.
4Plant Sprouted Root
After 4-6 weeks, your ginger root should be ready for planting in a pot. The largest roots and shoots should be a couple of inches long. I like flower pots with saucers like these ones.
This sprouted ginger is ready for planting after 6 weeks.
The whole thing may look odd but if there’s new growth, you’re good.
In the photo (above), I know that horn-shaped growth on the right is a shoot, not a root, so I have aimed it upward in the pot.
If you are planting more than one sprouted ginger, use a nice wide pot and place them side by side with a few inches space between them for the rhizomes to expand.
Pot Size and Potting Mix
Choose a pot several inches wider than your ginger root is long. If it’s 3-inches long, use a 6 to 8-inch wide x 6-inch deep pot with drainage holes. These plants grow wider as the root spreads.
- Fill pot with houseplant potting mix (we use the words ‘potting mix’, ‘growing medium’, and ‘soil’ interchangeably here but never use garden soil), water thoroughly, and gently press soil mix down into pot.
- Plant sprouted ginger two inches below lip of pot. If you can tell which part is a shoot, aim that up. If not, the plant will sort it out as it grows.
- Cover with additional inch of potting mix and water again. All parts of the ginger should be covered.
5Ginger Plant Care
Place your ginger pot in a warm, sunny (not hot) location.
- The ideal growing temperature is higher than many of us keep our homes (75-85°F | 24-29°C). My house stays around 65-75°F (18-24°C) and it’s growing fine.
- Keep soil moist (not soaking wet).
- Like many tropical plants, ginger likes 40-50% relative humidity. Some gardeners use a drip tray filled with water to catch water spills.
In 2-4 weeks, a shoot should emerge from the soil:
Ginger plant growth two weeks after planting sprouted ginger rhizome in potting mix.
Here it is about a month later:
Ginger plant 11 weeks after putting rhizome in damp paper towel.
Six weeks after planting, my most recent ginger plant is 3-feet tall with one single stalk and 7 long, narrow leaves. It resembles a very tall, thick blade of grass.
As the plant grows, new ginger roots will develop in the potting mix.
Fertilizer
- If you’re going to eat the ginger rhizome, pick a safe, slow-release organic fertilizer suitable for food crops.
- I switch around to test different products but right now I’m using a fish emulsion in very low doses each time I water.
Harvesting Ginger
- After a few years of growth, you can harvest some of the roots once per year, leaving the rest to continue growing.
- The older the ginger root, the better the flavor.
- You can also divide the older rhizomes to create several new plants.
Outdoor Summer Care
- During warm months, you can keep your ginger outdoors in a sheltered location, avoiding blazing sun.
- Follow normal precautions when bringing it back indoors for the winter including cleaning the plant and inspecting for insects or diseases.
Frequently-Asked Questions
Yes, it is possible to roots some types of ginger from the grocery store. However, if the ginger has been treated with growth retardants, which are used to prevent sprouting in the store, it may not sprout for you at home either. There likely is not a way to check for this other than buying some and trying to sprout it.
That said, I always use grocery store ginger for mine and have never had a problem.
When you plant a ginger root (which is really a rhizome), it takes about 2-3 years for it to be mature enough to harvest. The older it is, the better the flavor.
Sprouting a ginger rhizome for planting takes a few weeks.
Ginger likes direct but not hot sun. Ginger is a tropical plant originating in the understory of a tropical forest, so it likes moisture and warmth but not direct, hot sun.
See the ginger plant care tips here.
Yes, you can grow ginger indoors year-round in Canada and outdoors as houseplant in summer. Ginger is a tropical plant, not a hardy perennial.
You do not need to soak ginger before planting. The paper towel rooting method offers all the moisture needed for ginger root (rhizomes) to sprout. If ginger is left to sit in water it will eventually rot.
To harvest ginger, dig up the rhizomes and cut off the amount you wish to use from the outer edges of the rhizome. Allow the cuts to heal for a few days then replant the remainder.
The edible part of a ginger plant is the rhizome, which is usually called the root.
Ginger is a spice. Herbs come from the leafy part of plants. Spices come from other parts of plants and trees including bark, roots, and seeds.
