– Citronella Grass vs. Lemongrass: Appearance
Citronella plants and lemongrass look very similar, especially for the ones who do not know the difference. However, if you look closely, there are visible differences between the two. The citronella plant has blade-shaped leaves that are wider than the lemongrass leaves.
These leaves are also tinged with red or magenta color close to the base of the plant. Lemongrass, on the other hand, has a green base and leaves. It is easier to distinguish between mature plants of these species than younger ones.
Lemongrass grows as big as two feet tall and spreads four feet wide, while citronella plants can reach up to six feet height and spread four feet wide.
– Mosquito Repellents
When it comes to the ability to fight mosquitoes, Lemongrass takes the lead. That explains why all the products that you see that are labeled as natural mosquito repellents are made from lemongrass essential oils.
On the other hand, citronella is also used as a mosquito repellent. The plant is grown in gardens and sold massively during summers in nurseries and plant shops. Citronella plants look good on patios as potted plants and become a good addition to landscapes.
Both plants are used for making the essential oil that repels mosquitoes. Lemongrass oil requires repeated applications to be most effective. It must not be applied directly to the skin, which is why the oil is added to lotions and creams and applied every hour.
There is a difference between lemongrass and citronella propagation. Lemongrass is grown easily in pots from the stalks brought from the market. These fresh stalks are soaked in water until they begin to root after two to four weeks. They are then transplanted into the garden.
Existing plants are multiplied by separating the baby plants from the base of the mature plant. Lemongrass likes to grow in full to partial shade and in loamy, rich soil. It is hardy in zones 10 to 11 but can be easily grown as a houseplant in other regions with proper care.
Citronella grass grows by division method too. It can be propagated through a mature plant that is two to three years old. Choose a healthy plant for division in the fall season.

Geraniol and citronellol is a chemical found in citronella plants, and these are antiseptics. This makes the citronella oil antiseptic too and perfect for use as disinfectants.
