There is one vegetable that has started to take pride of place in my kitchen. That is Lemongrass. The reason for this is that it is a staple ingredient of a lot of Thai and Chinese dishes, which I love. Buying Lemongrass is very expensive. To save money, I decided to grow it myself. I found it very easy to grow, and so will you.

Lemongrass, or Citronella, as it is otherwise known, is a tall perennial grass originating from Asia. It is easy to grow from the lemongrass stalks you can buy at supermarkets. It has a mild citrus or lemon scent that fills the house when used to cook.

Grow Lemongrass from the Supermarket at home.

One of the easiest ways to grow Lemongrass is from stalks from your supermarket. There are a few things to check when purchasing these Lemongrass stalks. Each must be in good condition, feel solid, and have some basal plate attached at the bottom. It is this basal plate that will produce roots.

When you are ready, get a glass jar, put around an inch of water in the bottom, sit the Lemongrass into this water, and leave it on a south-facing window sill. Change the water every few days. Around two weeks later, little roots appear from the basal plate. Once these are long enough, you can plant them into a pot of soil.

Allow the plants to establish and plant them out after the last frost date in your area. In very dry times, ensure you water your lemongrass regularly. To learn more about this procedure, check out the video below, where I show you all the steps to follow this process.

Grow Lemongrass At Home – The Easy Way

Grow Lemongrass From seed at home

Lemongrass from seed is straightforward. However, it needs to be started early in February as this will give the plants time to establish before they are put into their permanent homes.

Sow thinly into seed starter mix and cover with a fine layer of vermiculite, this will stop the light from getting to the seed but allow the seed to germinate quickly. Place this into a propagator to germinate. Coming from tropical Asia, it requires 17˚c or 62˚f to germinate. When seedlings are big enough, transplant them to their pots and grow until the last frost passes.

Is Lemongrass hard to grow?

As you have just read in the last two processes, Lemongrass is extremely easy to grow. Follow a few tips to ensure you have a good crop when needed.

  • At least 17˚c or 62˚f to germinate
  • Keep warm during the seedling stage
  • Provide plenty of water when growing
  • Place in a bright sunny position
  • Feed with a high-nitrogen feed
  • Ensure soil is well-draining soil

What are the growing conditions for Lemongrass?

I wanted to cover some of the growing conditions for lemongrass even though I have touched on it throughout the blog.

  • Sow into seed pots or trays in early Feb
  • It is not frosted tolerant, so it will need to be taken indoors if temperatures drop below -9˚c or 48˚f.
  • Feeding is not normally required. However, High nitrogen liquid feed can be used if the plant requires it.
  • Plant out plants with a spacing of 2 ft. These can get big
  • It can be a companion planted with Basil, Corriander or Echinacea
  • Harvesting leaves the stalks to become thick and only removes the outer part of the plant.
  • End of summer, divide the plant and put them into pots. Place on a sunny windowsill or conservatory to grow through winter
  • If the plant struggles, check the soil drainage as this can kill these plants if they get waterlogged.

Can Lemongrass survive the winter?

Lemongrass is the only hardy down to -9˚c or 48˚f. if your area has temperatures that drop below this, you would be much better off taking them indoors. If you can not dig them up or do not have the room, take a small split from the main plants and take this indoors through the winter as a backup should your main plants die.

How do you protect Lemongrass in the winter?

Leaving lemongrass out throughout winter is not an option unless you’re in a tropical region. Instead, dig it up and place it into a box or pot. Cut back the foliage to around 3 inches above the roots. Keep the plants cool and dark in a frost-free environment.

A garage with a window would be an ideal location. Do not allow the plants to freeze at any point. Water once every 6 to 8 weeks during winter to prevent the root system from drying out completely. In early spring, awaken the plant by bringing it out into the light and watering it as normal.
