Does Lemon Grass Come Back Every Year: Growing Tips
Does Lemon Grass Come Back Every Year?
Yes, lemongrass is a tender perennial that can come back every year if it is properly cared for.
However, it cannot tolerate cold weather and frost, so in USDA zones 8b and 9, it should be brought indoors.
Lemongrass requires full sun and well-drained soil, and should be planted 24 inches apart in the ground or in pots with a minimum diameter of 12 inches.
It needs a minimum of six hours of light per day and should be watered daily to prevent dehydration.
Lemongrass can be harvested when it reaches a height of 12 inches and a stem base thickness of at least 0.5 inches.
While it can be grown in containers, it does not do well as a strictly indoor plant due to lack of light.
If growing lemongrass over winter, it should be lifted in early autumn, potted up, and grown in a greenhouse with a minimum temperature of 45°F.
It can also be grown from seed and will be ready to harvest 75-100 days after sowing, continuing to grow until the first hard frost in fall.

Lemongrass: A Tender Perennial Requiring Proper Care
Lemongrass, also known as Cymbopogon citratus, is a tender perennial plant that has the potential to come back every year if the right care is provided. However, it is important to note that lemongrass cannot tolerate cold weather and frost, making it necessary to bring the plant indoors in USDA zones 8b and 9 during the winter months.
To ensure the longevity of lemongrass, it needs to be grown in an environment that provides full sun and well-drained soil. Lemongrass requires a minimum of six hours of light per day, making it ideal for placement in a sunny spot in your garden or balcony. Additionally, it is crucial to provide adequate watering to prevent dehydration, ensuring that the soil is consistently moist.
The Importance Of Indoor Protection In Cold Weather
Lemongrass is a plant that is sensitive to cold weather and frost, so it needs to be protected indoors during the winter months. If you live in USDA zones 8b and 9, it’s crucial to bring lemongrass indoors to prevent damage from freezing temperatures.
When moving lemongrass indoors, it is recommended to lift the plants in early autumn and pot them up. Choose a pot with a minimum diameter of 12 inches to give the plant enough space to grow. Place the potted lemongrass in a greenhouse or a well-lit area with a minimum temperature of 45°F to maintain its optimal growth conditions.
Sunlight And Drainage: Key Factors For Lemongrass Growth
Sunlight and proper drainage are key factors that contribute to the successful growth of lemongrass. Lemongrass requires full sun to thrive, meaning it should be placed in an area that receives direct sunlight for at least six hours each day. This ensures the plant receives sufficient light energy for photosynthesis and overall healthy growth.
Moreover, well-drained soil is essential for lemongrass. It thrives in soil that allows excess water to drain away, preventing waterlogging which can lead to root rot. Before planting lemongrass, ensure the area has good drainage by incorporating organic matter or creating raised beds if needed. Proper drainage ensures the roots are not sitting in water, promoting a healthy and robust lemongrass plant.
Planting And Spacing Guide For Lemongrass
When planting lemongrass, it is important to consider the appropriate spacing to allow each plant to grow and flourish. Whether you choose to grow lemongrass in the ground or in containers, proper spacing is crucial for optimal growth.
In the ground, lemongrass should be planted 24 inches apart to allow adequate space for the plant’s growth habit. This spacing provides enough room for each plant to fully develop and expand without competing for resources.
If growing lemongrass in containers, it is recommended to plant one plant per pot with a minimum diameter of 12 inches. This allows ample space for the plant’s root system and ensures that it has enough room to grow and establish itself.
- Plant lemongrass 24 inches apart when growing in the ground.
- Plant one lemongrass plant per pot with a minimum diameter of 12 inches when growing in containers.
Watering And Harvesting Tips For Healthy Lemongrass Growth
Proper watering is essential for healthy lemongrass growth. It is important to provide consistent moisture to the plant, as lemongrass can quickly become dehydrated. Water the plant regularly, ideally daily, ensuring the soil stays moist but not waterlogged. This will help prevent the plant from drying out and promote healthy growth.
When it comes to harvesting lemongrass, timing is crucial. Once the lemongrass reaches a height of 12 inches and a stem base thickness of at least 0.5 inches, it is ready for harvest. Gently cut the stalks near the base, leaving enough of the plant to allow for regrowth. Harvesting can be done throughout the growing season, ensuring a continuous supply of fresh lemongrass until the first hard frost in fall.
Lemongrass is a tender perennial that can come back every year with proper care. While it requires full sun and well-drained soil, it cannot tolerate cold weather and frost. By bringing lemongrass indoors during winter, providing adequate sunlight and drainage, and following proper planting and spacing guidelines, you can ensure a healthy and bountiful lemongrass harvest. With these tips, you can successfully grow lemongrass year after year in your garden or containers.

Frequently Asked Questions
Will lemongrass regrow?
Yes, lemongrass has the remarkable ability to regrow. By cutting all the leaves down to 10cm (4in) from the base in autumn, you can ensure that it will resprout in spring. This technique is especially handy for those who have limited indoor space during the colder months. Alternatively, cutting back in early spring, before new growth starts, can also promote regrowth of lemongrass. So, whether you’re looking to save space or encourage new growth, lemongrass is resilient and capable of regrowing.
What is the lifespan of a lemongrass plant?
Although lemongrass is a perennial plant, it generally thrives for approximately four years before its vitality declines, necessitating a complete harvest and subsequent replanting. In culinary traditions from Southeast Asia and India, the leaf bases, known as stalks, are commonly utilized to add flavor to various dishes. Moreover, the tender core of young shoots can be cooked and enjoyed as a delectable vegetable.
How do you preserve lemongrass?
To preserve lemongrass for extended periods, freezing is an excellent method. To do this, start by removing the leaves and root ends from the stalks, and then freeze the whole stalks on a cookie sheet. Ensuring space between them is essential to prevent them from freezing together. Once frozen, transfer the stalks into a freezer-proof container. Likewise, sliced lemongrass can be frozen following the same procedure. This freezing technique retains the vibrant flavor and aroma of lemongrass, allowing it to be readily available for use in future culinary endeavors.
Can lemongrass grow without sunlight?
While lemongrass thrives in full sun and requires an ample amount of water and nutrient-rich soil, it is possible for it to grow in limited sunlight. Although it may not reach its full potential without adequate sunlight, lemongrass can still grow and survive in partially shaded areas. In such conditions, it may require extra care and attention to ensure that it receives enough water and nutrients for optimal growth. However, if you are aiming for a robust and flourishing lemongrass plant, providing it with ample sunlight is highly recommended.
