Appearance
Kalanchoe citrina Schweinf. has a distinctive, compact growth habit and can grow up to 12-18 inches tall. The leaves are thick, fleshy, and have a scalloped or ruffled edge. They are a pale green color and have a lavender hue on the undersides.
The plant produces bright, lemon-yellow flowers that bloom in clusters on the end of long stems. These flowers are tubular in shape and have five petals. They bloom for several weeks during the spring and summer months.
Uses
Kalanchoe citrina Schweinf. is primarily grown as an ornamental plant, as it is attractive in both foliage and flower. It is often used in rock gardens, container gardens, and as indoor plants.
Some species of Kalanchoe have medicinal uses, and Kalanchoe citrina Schweinf. is no exception. It has been used traditionally to treat headaches, inflammation, and as an antimicrobial agent. However, further research is needed to confirm the effectiveness of these treatments.
Light Requirements
Kalanchoe citrina Schweinf. grows best in bright, filtered light, although it can tolerate low light conditions. It should be protected from direct sunlight, as this can burn the leaves and cause them to shrivel.
Temperature Requirements
This plant thrives in warm temperatures, ideally between 60 and 85 degrees Fahrenheit (15-29 Celsius) during the day and no cooler than 50 degrees Fahrenheit (10 Celsius) at night.
Soil Requirements
The soil should be well-draining, with a pH ranging from slightly acidic to slightly alkaline (6.0-7.5). A typical potting mix with added perlite for drainage is suitable. It is important to avoid overwatering, as this can lead to root rot.
Cultivation
Kalanchoe citrina Schweinf. is a hardy plant that is relatively easy to cultivate. It is tolerant of a wide range of growing conditions and can be grown both indoors and outdoors.
If planting outdoors, choose a location that has well-draining soil and is exposed to partial sunlight. The plant can also be grown indoors using a well-draining potting mix.
The plant is best propagated using stem cuttings. Make sure that the cuttings are taken from healthy plants and that they are allowed to dry for a few days before planting. Once planted, the cuttings should be kept in a warm, humid environment and watered regularly until they have established roots.
Watering Needs
Kalanchoe citrina Schweinf. has moderate water requirements and can tolerate short periods of drought. When watering, it is recommended to do so deeply and infrequently, allowing the soil to dry out partially between watering sessions.
Overwatering can lead to root rot and other issues, so be sure to allow the soil to dry out before watering again. It is also important to not water the leaves of the plant, as this can lead to fungal growth.
Fertilization
Kalanchoe citrina Schweinf. does not have high nutrient requirements and can typically do well without fertilization. However, if desired, a balanced fertilizer can be applied in the spring and summer months to support growth.
Be sure to follow the package instructions carefully when fertilizing, as overfertilizing can cause damage to the plant.
Pruning
Kalanchoe citrina Schweinf. does not require frequent pruning, but occasional pruning can help shape the plant and encourage bushier growth. Pruning should be done in the spring or summer months.
To prune, use sharp, clean pruning shears to remove any dead or damaged plant material. Cut back any overgrown stems to a healthy node or leaf, being careful not to damage the plant.
Propagation Methods for Kalanchoe citrina Schweinf.
Kalanchoe citrina Schweinf., also known as the citronella plant or lemon scented kalanchoe, is a succulent plant native to Madagascar that produces fragrant lemon-scented flowers. While this plant is generally low-maintenance, it can be propagated through several methods to produce new plants.
Leaf Cuttings
One of the most common propagation methods for Kalanchoe citrina is through leaf cuttings. To do this, select a healthy leaf from the mother plant and gently twist it off, making sure to keep the entire leaf intact. Allow the leaf to dry for a few days until the cut end calluses over. Dip the cut end in a rooting hormone powder and place the leaf on top of well-draining soil. Keep the soil moist and place the cutting in indirect sunlight. Roots should begin to sprout within a few weeks, and a new plant will begin to emerge from the base of the leaf.
Stem Cuttings
Another propagation method for Kalanchoe citrina is through stem cuttings. Take a stem cutting from the mother plant that is at least 3 inches long with several leaves attached. Dip the cut end in a rooting hormone powder and place it in a pot of well-draining soil. Keep the soil moist and place the cutting in indirect sunlight. Roots should begin to sprout within a few weeks, and a new plant will begin to emerge from the base of the stem.
Offsets
Kalanchoe citrina also produces offsets, or "baby plants," that can be removed from the mother plant and planted separately. These offsets typically appear at the base of the mother plant or in the soil around it. To propagate using offsets, gently remove the baby plant from the mother plant and plant it in a pot of well-draining soil. Keep the soil moist and place the new plant in indirect sunlight.
Seed Propagation
Finally, Kalanchoe citrina can be propagated through seed. Allow the plant to flower and produce seed pods. Collect the seeds once the pods have dried and opened. Sow the seeds in well-draining soil and keep the soil moist. Place the pot in bright, indirect light and ensure a consistent temperature of around 65-75 degrees Fahrenheit. Seedlings should begin to emerge within a few weeks.
Disease and Pest Management for Kalanchoe citrina Schweinf.
Kalanchoe citrina Schweinf., also known as the lemon scented kalanchoe, is a popular houseplant known for its fragrant blooms and easy care. However, like all plants, it is susceptible to various diseases and pests. It is important to properly manage these issues to ensure the health and vitality of the plant.
Common Diseases
Kalanchoe citrina can be affected by a range of fungal and bacterial diseases, including powdery mildew, leaf spot, and bacterial stem rot. Powdery mildew often appears as a white, powdery coating on the foliage, while leaf spot causes brown spots on the leaves. Bacterial stem rot causes the stem to soften and collapse.
To manage fungal and bacterial diseases, it is important to provide proper air circulation and avoid over-watering. Remove affected leaves and stems and treat with a fungicide or bactericide if necessary.
Common Pests
Kalanchoe citrina is also susceptible to a range of pests, including spider mites, mealybugs, and scale insects. Spider mites are tiny pests that cause leaves to yellow and become speckled. Mealybugs are white, fuzzy pests that suck sap from the plant, often causing a sticky residue on the leaves. Scale insects appear as small bumps on the stem and leaves, and can cause the plant to wilt and die.
To manage pests, it is important to regularly inspect the plant and quickly remove any affected leaves or pests. Wipe down the leaves with a damp cloth and use an insecticide if necessary. It is also important to avoid over-fertilizing or over-watering, as this can attract pests.
Overall, proper care and management of diseases and pests is key to maintaining a healthy and thriving Kalanchoe citrina plant. With regular inspection and prompt action, these issues can be effectively managed to ensure the long-term health and beauty of the plant.
