For any gardener, learning how to propagate a citronella plant is especially fulfilling since it blends practical expertise with the joy of creating life from a single cutting. Citronella has long been praised for its beauty and peaceful presence, and it is well-known for its vivid green leaves and crisp, lemon-like scent. Regardless of your preference for tall grass or scented geraniums, propagation makes it possible to produce more of these fragrant plants for almost nothing.

Choosing a healthy mother plant is the first step in the procedure. Pick one with lots of leaves and robust, green stalks. Cut a 4- to 6-inch portion off a non-flowering stem with clean, sharp pruning scissors. Taking cuttings early in the morning, when the plant is at its hydration peak, is incredibly beneficial since it maximizes water retention and reduces stress on the new cutting. At least two nodes should be present in the cutting because these are where roots and leaves will eventually appear.

Remove the majority of the leaves after taking the cutting, leaving only two at the top. Because it stops the cutting from losing too much moisture through transpiration, this procedure is especially helpful. Reduce the size of the remaining leaves to around half if they are huge. As the plant concentrates its energy on root development, you can help it conserve water by decreasing the surface area.
Before planting, immerse the recently cut end into a rooting agent for quicker results. Natural hormones included in rooting chemicals, which are very effective growth stimulants, promote the production of roots. Even though they are optional, they can greatly accelerate the rooting process and raise the likelihood of success. After coating, put the cutting in a tiny pot with moist potting mix that drains well; for best aeration, use a mixture of peat and perlite.
Place the pot where it will receive bright, indirect sunshine. The young cutting may wilt before it develops roots if it receives too much direct exposure. New roots should start to grow in two to three weeks. Pull the cutting gently to see how it's progressing; if it resists, roots have formed. Move the young citronella plant into a bigger pot or straight into the garden once the roots are secure.
Citronella plants require a minimum of six hours of sunshine per day to flourish. They thrive outdoors year-round in USDA zones 9b through 11 and grow especially well in warm, temperate areas. They can still be enjoyed as annuals or overwintered indoors by a sunny window in colder climates.
Watering is crucial to the process of multiplication and upkeep. The soil should be continuously moist but never waterlogged throughout the early stages of growth. Citronella geraniums can withstand drought rather well once they reach maturity, but frequent watering keeps the foliage looking lush and healthy. Before watering, always inspect the soil; if the top inch seems dry, it's time for a watering. However, one of the few problems that can rapidly jeopardize the effectiveness of propagation is root rot, which can result from overwatering.
Additionally, frequent pruning keeps the plant bushy and compact. Removing lanky stems promotes new growth and improves the scent in general. Pruning your citronella plant responsibly will make it fuller and more fragrant; many seasoned gardeners find this method to be incredibly useful for preserving vigor.
Citronella is a family favorite due to its link with insect repellent. It's crucial to emphasize, though, that the plant itself doesn't effectively deter mosquitoes unless its leaves are crushed to release the essential oils. Even so, the impact is moderate and transient. Most commercial repellents are based on citronella oil, which is extracted from citronella grass rather than the geranium. Because of their smell and elegant leaves, both varieties of citronella are still prized ornamental plants.
Cymbopogon nardus, the scientific name for the actual citronella grass, needs to be propagated by a somewhat different process called root division. To do this, a mature clump of grass must be dug up and divided into smaller pieces, making sure that each part has a robust root system. Replanting the divisions in loamy, nutrient-rich soil and giving them regular watering is recommended. The grass is perfect for large gardens or outdoor borders because it can reach an astounding six feet in height.
Filtered sunlight is frequently the best for growing citronella grass. In warmer climates, filtered exposure helps avoid leaf scorch, even though the plant can withstand direct light. Citronella grass grows very well in large containers for gardeners in colder climes. The plant will continue to flourish if these containers are brought indoors before the onset of frost.
A growing interest in sustainable gardening across society has led to a recent boom in the propagation and maintenance of citronella plants. Compared to purchasing new plants, propagating plants from cuttings is significantly more economical and environmentally friendly. It also reduces waste and strengthens the bond between gardeners and their surroundings. It symbolizes a subtle but significant move toward independence, one that many home gardeners and proponents of green living also follow.
Unexpectedly, social media sites like Instagram and TikTok have played a significant role in this comeback. Numerous novices have been encouraged to start growing citronella by videos that demonstrate propagation methods, which range from transplanting to cutting care. Horticulture aficionados and influencers frequently emphasize how easy and fulfilling the process can be, stressing that perseverance and patience produce incredibly beautiful results.
Similar tendencies among environmentally aware celebrities who advocate for sustainability and natural living are reflected in this shift toward home propagation. Environmentally conscious celebrities like Emma Watson and Shailene Woodley have openly promoted plant-based pastimes as a way to practice mindfulness and self-care. With its mild scent and soothing aesthetic appeal, the citronella plant is a wonderful complement for this expanding way of life.
For those who like to add personal touches, trying different plant placements and combining citronella with herbs that go well together, like basil, lavender, or rosemary, can result in garden arrangements that are both aesthetically pleasing and fragrantly pleasant. Additionally, these pairings draw pollinators like butterflies and bees, which gives any green area a boost of vitality.
