Citronella vs Meyer Lemon Plant Comparison
Compare these two plants side by side — care needs, key differences, and which is right for your home.
Citronella
Cymbopogon nardus or Cymbopogon winterianus
Citronella is a perennial clumping grass known for its distinct citrusy scent, primarily due to the presence of citronellal and geraniol in its leaves. It typically grows to a height of 3-6 feet. It's primarily grown outdoors for its mosquito-repelling properties, although the effectiveness is debated and requires crushing the leaves to release the oils. It is not naturally an indoor plant and requires very specific conditions to thrive indoors.
Meyer Lemon
Citrus × meyeri
The Meyer lemon is a citrus fruit thought to be a hybrid between a lemon and a mandarin orange. It is smaller and rounder than a true lemon, with a smoother, thinner skin that is a deep yellow-orange when ripe. The flesh is also a darker yellow and less acidic than a standard lemon. Meyer lemons are often grown for their ornamental value as well as their fruit. While they can be grown indoors, they require very specific conditions to thrive and produce fruit. They are prized for their sweeter juice and fragrant zest, making them popular in cooking and baking.

❓ Frequently Asked Questions — Comparing These Plants
Citronella
What are the light requirements for Citronella?
Citronella plants need a good amount of sunlight to thrive. Aim for at least 6 hours of direct sunlight per day for optimal growth and mosquito-repelling potency. If growing indoors, place the plant near a sunny window, preferably south-facing. If natural light is insufficient, supplement with grow lights.
How do I care for Citronella?
Citronella plants thrive in well-draining soil and prefer full sun to partial shade. Water regularly, allowing the soil to dry slightly between waterings. Avoid overwatering, which can lead to root rot. Fertilize every 4-6 weeks during the growing season (spring and summer) with a balanced fertilizer to promote healthy growth and flowering.
How do I propagate Citronella?
Citronella can be propagated through several methods. Division involves separating the plant into smaller clumps and repotting them. Stem cuttings can be taken from healthy stems and rooted in water or soil. Keikis, or baby plants, sometimes form on mature plants and can be carefully removed and potted.
Meyer Lemon
What are the light requirements for Meyer Lemon?
Meyer Lemon trees thrive in bright, direct sunlight. Aim for at least 6-8 hours of direct sunlight per day. A south-facing window is ideal, but east or west-facing windows can also work if supplemented with grow lights. Insufficient light can lead to leggy growth, reduced flowering, and smaller, less flavorful fruit. During the winter months, when natural light is limited, supplemental lighting is crucial for maintaining the tree’s health and productivity. Rotate the tree regularly to ensure that all sides receive adequate light exposure. Consider using a full-spectrum LED grow light positioned close to the tree for optimal results.
How do I care for Meyer Lemon?
Caring for a Meyer Lemon tree indoors requires attention to several key factors. First, provide at least 6-8 hours of direct sunlight per day, ideally from a south-facing window. Supplement with a grow light if necessary. Water thoroughly when the top inch of soil is dry, ensuring good drainage to prevent root rot. Use a well-draining potting mix formulated for citrus trees. Fertilize regularly during the growing season (spring and summer) with a citrus-specific fertilizer. Prune to maintain shape and remove any dead or crossing branches. Maintain a consistent temperature between 65-75°F (18-24°C) and provide adequate humidity, especially during dry winter months. Repot every 2-3 years as needed, selecting a pot only slightly larger than the previous one. Monitor for pests such as aphids or spider mites and treat promptly. Regularly rotate the tree to ensure even growth.
How do I propagate Meyer Lemon?
Meyer Lemon trees can be propagated through stem cuttings or air layering. For stem cuttings, take a 4-6 inch cutting from new growth in the spring. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in a well-draining potting mix and keep it moist in a humid environment. For air layering, make a small incision on a branch, wrap it in moist sphagnum moss, and cover it with plastic wrap. Once roots develop, cut the branch below the moss and plant it in a pot. Rooting can take several weeks to months. Provide warmth and humidity to encourage root growth. Use a rooting hormone to increase success rate. Patience is key.
