What is lemongrass?
Lemongrass is a fast-growing tropical herb with a lemony aroma and taste. Native to India and Sri-Lanka, this herb features in many Asian dishes for its zesty flavor and aroma.

In areas that receive a lot of direct sunlight and water, lemongrass plants will grow rapidly and in thick clumps.
Potted lemongrass plants require a pot that is at least 12 inches wide. To ensure good drainage and a good root network, make sure your pot is deep enough to support your lemongrass plant.
How to propagate lemongrass?
As lemongrass grows in clumps, it is easy to propagate lemongrass plants. Here is how to propagate lemongrass by division:
- Dig up a clump of lemongrass.
- Each clump of lemongrass has leaf fans that are attached to a bulb-like base, with roots attached. Each of the bulbs with roots attached can grow into individual clumps. With a spade, you can divide your clump into pieces containing at least five or six of these bulbs attached.
- Replant the divisions immediately in new pots or in your plant beds.
- Water thoroughly and be sure to water your divisions daily.
You can also germinate your lemongrass seeds and plant them in your plant beds. However, lemongrass seeds are hard to find, as most retailers sell living planters that are to be transferred as they grow.

How quickly your lemongrass plant grows and how thick the grass is depends on the quality of your potting soil. Choose a potting soil with premixed fertilizer to keep your plants fed and healthy all year around.
Growing lemongrass in colder climates is far trickier than growing the plant under warm conditions. However, during the winter, you can still grow a single bulb in a small pot on a sunny spot or windowsill. It’s best to repot your plant in the spring, before the warm months for rapid and healthy growth.
