The plant produces small flowers that are yellowish-green in color and are not the main attraction of the plant. Here are the typical growth conditions for Dorstenia scabra var. longicaudata:
Light Requirements
Dorstenia scabra var. longicaudata prefers indirect bright light or partial shade. It can tolerate full sun but not for extended periods, as too much sunlight can scorch the leaves. The plant can be grown in a north-facing window or outdoors under the shade of other plants.
Temperature Requirements
This plant thrives in warm temperatures ranging from 20°C to 30°C. It can tolerate low temperatures of up to 10°C, but this should only be for a short period. Extreme temperatures should be avoided as it can lead to stunted growth or death of the plant.
Soil Requirements
The preferred soil for Dorstenia scabra var. longicaudata is well-draining soil with good aeration and a slightly acidic to neutral pH level. The soil should contain a good amount of organic matter and perlite or sand to help with drainage. Avoid using heavy soils that retain too much water as this can cause root rot.
Watering Requirements
Water the plant when the soil is dry to the touch. The frequency of watering will depend on the temperature and humidity in the growing location. Overwatering should be avoided, as it can cause the leaves to turn yellow and fall off. Ensure that there is good drainage to prevent waterlogging.
Fertilizer Requirements
Feed the plant with a balanced fertilizer every four weeks during the growing season, from spring to summer. It is recommended to use a liquid fertilizer with a lower nitrogen content as high nitrogen levels can cause weak stems and leaves. Fertilizer should be avoided during the winter months when the plant is dormant.
Cultivation
Dorstenia scabra (Bureau) Engl. var. longicaudata Engl. can be grown outdoors in a tropical climate or indoors as a houseplant. It prefers well-draining soil and requires bright, indirect light to grow properly. The plant can be propagated by cuttings or seeds, but cuttings tend to be more successful.
Watering Needs
The watering needs of Dorstenia scabra (Bureau) Engl. var. longicaudata Engl. vary depending on the season. During the growing season, the plant should be watered once a week or when the top inch of the soil feels dry. In the dormant season, the plant can be watered sparingly, only when the soil has completely dried out. Overwatering can lead to root rot, so it is essential to allow the soil to dry out between waterings.
Fertilization
Dorstenia scabra (Bureau) Engl. var. longicaudata Engl. benefits from monthly fertilization during the growing season. A balanced, water-soluble fertilizer can be used at half strength to avoid over-fertilization. Fertilization can be skipped during the dormant season.
Pruning
Dorstenia scabra (Bureau) Engl. var. longicaudata Engl. does not require extensive pruning. However, if the plant is grown outdoors, it may need occasional pruning to maintain its shape. Pruning should be done during the growing season, using clean, sharp pruning shears. Any dead or diseased leaves or stems should be removed promptly to maintain the plant's health.
Propagation of Dorstenia scabra var. longicaudata
Dorstenia scabra var. longicaudata can be propagated through a few different methods, including seed and stem cuttings.
Seed Propagation
Seeds of Dorstenia scabra var. longicaudata can be obtained from mature fruits that are allowed to fully ripen and then split open. The seeds should be cleaned of any attached pulp and soaked in water for a few days to help soften the seed coat. After soaking, the seeds can be planted in a well-draining seed-starting mix.
The pots should be placed in a warm, bright location and kept consistently moist until the seedlings emerge, which can take several weeks. Once the seedlings have grown large enough to handle, they can be transplanted into individual pots and cared for in the same way as mature plants.
Stem Cutting Propagation
Dorstenia scabra var. longicaudata can also be propagated by stem cuttings. Cuttings should be taken from mature stems that are at least 4 inches long and have several leaves attached. Cuttings should be made using a clean, sharp knife and then allowed to dry for a day before being planted.
The cuttings should be planted in a well-draining potting mix and kept consistently moist. It may be helpful to cover the pot with a clear plastic bag to help maintain humidity and encourage rooting. After several weeks, the cuttings should begin to develop roots and new growth. At this point, the plastic bag can be removed and the plants can be cared for in the same way as mature plants.
