Kalanchoe obtusa Engl. is also used in traditional medicine and is believed to have medicinal properties, such as anti-inflammatory and anti-tumor properties. The leaves are also used in cooking and added to salads to give them a sour taste.
Light Requirements
The Kalanchoe obtusa plant prefers bright, indirect sunlight. Direct sunlight should be avoided as it can damage the plant's leaves. It can tolerate low light conditions, but it may affect the flowering of the plant.
Temperature Requirements
The ideal temperature for Kalanchoe obtusa ranges from 60 to 75 degrees Fahrenheit. Temperatures below 50 degrees Fahrenheit can be harmful to the plant. It is important to keep the plant away from cold drafts.
Soil Requirements
Kalanchoe obtusa prefers well-drained soil that is slightly acidic to neutral. The soil should be moist but not waterlogged. Adding organic matter to the soil can help improve drainage and fertility. The plant can also grow well in containers with good drainage holes.
Cultivation methods for Kalanchoe Obtusa Engl.
Kalanchoe Obtusa Engl., also known as 'Feltbush,' is an attractive indoor succulent that is accustomed to growing in rocky, well-drained soil. It is a hardy plant that thrives in tropical or subtropical regions, and its best cultivation practice is through vegetative propagation using stem cuttings or division.
When propagating through stem cuttings, the stem's lower part must be allowed to dry out for at least two days to reduce the risk of rotting. You can then plant the cuttings in a potting mix made up of coarse sand, peat, and perlite.
The potting soil should be moist but not waterlogged, and should be positioned in a bright location and warm temperature. You can transplant the kalanchoe, once it has developed roots, into a pot or container that is at least 8 inches in diameter.
Watering needs for Kalanchoe Obtusa Engl.
The kalanchoe prefers moderate watering, which means you should water it thoroughly, then let the soil dry out between each watering session. Make sure you do not over-water it because it is prone to easily rot if it remains damp for long periods.
The rule of thumb is to water your kalanchoe when the soil's top layer is dry to the touch. Irrigate the potting mixture, allowing the excess water to drain through the drainage holes at the base of the container to prevent the kalanchoe's roots from becoming waterlogged.
Fertilization of Kalanchoe Obtusa Engl.
For optimum growth, feed your kalanchoe once every two weeks with a balanced liquid houseplant fertilizer. The feed should be mixed as instructed on the package and applied to the damp soil.
Reduce the frequency of fertilizer application during the winter months, allowing the plants to slow down or become dormant.
Pruning Kalanchoe Obtusa Engl.
Generally, pruning is not essential for kalanchoe plants, but you can prune them to maintain their shape and size if you wish. Use sharp, sterile scissors to prune back kalanchoe branches when they become overgrown or too leggy. Cut back to a node where new growth can emerge.
You may also want to remove any dead flowers or leaves from the kalanchoe to encourage bushier growth and keep the plant looking tidy.
Remember to always wear gloves when pruning because the kalanchoe's sap can cause allergic reactions in some individuals.
Propagation of Kalanchoe Obtusa Engl.
Kalanchoe obtusa Engl., commonly known as the Velvet Leaf Kalanchoe, is a popular indoor succulent. Propagation of this plant is relatively easy, and it can be propagated using several methods. The preferred propagation methods are:
Leaf Cutting Propagation
Leaf cutting propagation is a common method of propagating Kalanchoe obtusa Engl. Take a healthy leaf from the plant and cut it close to the stem using a sharp knife. Allow the leaf to air dry for a day or two until the cut calluses over. After this, plant the callused end of the leaf in well-draining soil or rooting mix. Keep the soil moist, but not wet, and in a warm, bright location with indirect sunlight. In a few weeks, new roots will start to grow, and a new plant will develop from the leaf. When the plant has developed enough, transplant it to a new pot.
Cutting Propagation
Cutting propagation is another effective method of propagating Kalanchoe obtusa Engl. Using a sharp and clean knife or scissors, cut a stem of the plant near the bottom or at a leaf node. Remove the lower leaves from the cutting, leaving only a few on top. Dip the end of the cutting in rooting hormone powder and plant it in well-draining soil or rooting mix. Keep the soil moist, but not wet, and in a warm, bright location with indirect sunlight. In a few weeks, roots will start to form, and new growth will emerge at the top. After this, transplant it to a new pot.
Division Propagation
Division propagation is also possible for Kalanchoe obtusa Engl. During the plant's active growth phase, remove the plant from the pot, and gently tease the soil away from the roots. Separate the plant into smaller sections, ensuring each section has a few leaves and roots. Plant each new section into a new pot with fresh, well-draining soil. Water lightly, and keep in a warm, bright location with indirect sunlight. In a few weeks, new growth will appear, indicating that the plant has rooted.
Overall, Kalanchoe obtusa Engl. propagation is quick and straightforward. With a little patience and the correct conditions, you can have a beautiful new plant in no time.
Disease and Pest Management for Kalanchoe Obtusa Engl.
Kalanchoe obtusa Engl. is a beautiful succulent plant that is widely grown for its attractive foliage and colorful flowers. Like all plants, it is prone to attacks by pests and diseases in certain conditions. Proper care and timely intervention can help prevent and control these problems.
Common Diseases of Kalanchoe Obtusa Engl.
1. Root Rot: Kalanchoe obtusa Engl. is susceptible to root rot caused by waterlogging or soil that is too wet. Symptoms include wilting, yellowing of the leaves, and brown, mushy roots. To prevent root rot, ensure proper drainage, avoid overwatering, and use well-draining soil. In case of infection, repot the plant in fresh soil and prune off any diseased roots.
2. Powdery Mildew: Powdery mildew is a fungal disease that appears as a white or grayish powder on plant leaves, stems, and flowers. It thrives in warm, humid conditions. To prevent this disease, avoid overhead watering and crowding of plants. If your plant is infected, remove the affected parts and apply a fungicide.
3. Mealybugs: Mealybugs are common pests that attack Kalanchoe obtusa Engl. They are small, white insects that suck sap from the leaves and stems, causing yellowing and stunted growth. To control mealybugs, mix a solution of soapy water and apply it to the plant using a cotton ball or a soft brush. Repeat after a few days if necessary.
Common Pests of Kalanchoe Obtusa Engl.
1. Spider Mites: Spider mites are tiny creatures that are barely visible to the naked eye. They spin webs on the leaves and suck sap from the plant, causing yellowing and browning of the foliage. To control spider mites, spray the plant with water to wash off the webs and use a miticide.
2. Scale Insects: Scale insects are small, oval-shaped insects that attach themselves to the plant and suck sap from it. They leave behind a sticky residue that attracts ants and causes the leaves to turn yellow and drop off. To control scale insects, use a cotton ball soaked in alcohol to remove them from the plant. Use insecticidal soap to prevent further infestation.
3. Aphids: Aphids are small insects that pierce the plant's leaves and suck out the sap, causing curling and yellowing of the foliage. They are usually found in large numbers on the new growth of the plant. To control aphids, remove infested leaves and spray the plant with a jet of water. Alternatively, use an insecticidal soap or a systemic insecticide.
By taking proper care of your Kalanchoe obtusa Engl. and keeping an eye out for signs of pests and diseases, you can help keep it healthy and beautiful for years to come.
