Dichostemma zenkeri Pax prefers bright, indirect light. It grows well when placed near a south or west-facing window where it can receive bright light for around 4-6 hours a day. Direct sunlight should be avoided as it can scorch the plant's leaves.
Temperature Requirements
The plant requires warm temperatures and does well in average room temperatures of 60°-75°F (15.6°C to 24°C). It is intolerant of cold drafts and sudden temperature changes, which can cause stunted growth or leaf dropping.
Soil Requirements
Dichostemma zenkeri Pax prefers a well-draining, nutrient-rich soil. A good potting mix should be composed of a mixture of peat moss, perlite, and coarse sand. The pH should be neutral, ranging between 6.0 and 7.5. The soil should be kept moist, but not soggy, as overwatering can cause root rot and other fungal diseases.
Fertilizer Requirements
The plant also requires regular fertilization. A balanced liquid fertilizer, such as a 20-20-20, should be applied to the plant's soil every two weeks during the growing season (spring and summer). This helps to promote growth and flowering. During the fall and winter months, fertilization should be reduced to once a month.
Humidity Requirements
Dichostemma zenkeri Pax requires high humidity to thrive. It is best to place it on a tray filled with pebbles and water to help increase humidity. Also, misting the leaves regularly will help keep the plant's foliage from drying out.
Propagation Requirements
The plant can be propagated easily by dividing rhizomes in the spring. Cuttings of the plant's tubers can also be taken and planted in well-draining soil. The cuttings should be kept in a humid environment with bright, indirect light and kept moist at all times.
Cultivation methods
Dichostemma zenkeri Pax is one of the plants that can tolerate a wide range of conditions, making it easy to cultivate. The plant prefers well-draining soil and can survive in various types of soils, including sandy, loamy, and clay soils. The recommended pH range for the soil is 5.6 to 7.5. The plant grows best in partially shaded areas, but it can also thrive in full sunlight exposure. It is a low maintenance plant and does not require any special care.
Watering needs
Dichostemma zenkeri Pax requires moderate watering. Watering should be done when the soil is dry to the touch. Overwatering should be avoided because it can lead to root rot and other diseases. During the winter season, the plant requires less water as its growth slows down. Watering should be done at the base of the plant and not on the leaves to avoid fungal growth and diseases.
Fertilization
Fertilization should be done during the growing season, which is during spring and summer. A balanced fertilizer with an NPK ratio of 10-10-10 is recommended. The fertilizer should be applied once a month, and the plants should be watered immediately after application. Over-fertilization should be avoided because it can lead to the burning of the leaves and other parts of the plant.
Pruning
Dichostemma zenkeri Pax does not require extensive pruning. However, to promote healthy growth and maintain its shape, prune the plant after blooming. Remove dead flowers and yellowing leaves to encourage the growth of new foliage. Pruning can also be done to control the size of the plant, and any damaged stems should be removed. Sterilized pruning tools should be used to avoid introducing diseases.
