The plant prefers well-drained soil that remains moist throughout the growing season. It does well in acidic soils with a pH range between 5.5-7.5. A mixture of organic compost and loam soil provides the ideal environment for healthy growth. Additionally, the soil should be rich in nutrients since this plant is known to be a heavy feeder.
Cultivation
Dombeya cincinnata K.Schum., commonly known as tropical rose mallow, is a warm-weather plant native to Africa. It is a tree that can grow up to 20 meters tall. When cultivated outside of its native environment, it can be grown in gardens or in containers. It requires a well-draining soil and a location that receives full to partial sunlight.
Watering needs
When watering Dombeya cincinnata K.Schum., it is essential to keep the soil moist. Water the plant regularly during the dry season, and reduce watering during colder months to avoid over-saturation. Avoid over-watering, which can cause root rot and harm the plant.
Fertilization
Dombeya cincinnata K.Schum. is a heavy feeder, so regular application of fertilizer is essential for optimal growth. A balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium is ideal. Apply fertilizer once every two weeks during the growing period.
Pruning
To maintain a proper shape and promote healthy growth, it is essential to prune Dombeya cincinnata K.Schum. after flowering. This will also help to remove any dead, damaged, or diseased branches. Pruning should be done before new growth appears in the spring.
Propagation of Dombeya cincinnata K.Schum.
Propagation of Dombeya cincinnata K.Schum. is generally done through seed or stem cuttings.
Propagation through Seeds
Seeds from mature pods can be collected in the late summer or fall and kept in a cool, dry place until the following spring, when they can be sown in a well-draining potting mix. The seeds should be barely covered with soil and kept moist until they germinate, which can take up to 2 months. Once the seedlings have developed a few sets of leaves, they can be transplanted to individual pots and grown under bright, indirect light until they are large enough to transplant outdoors.
Propagation through Stem Cuttings
Stem cuttings can be taken from mature plants in the late spring or early summer. Choose a stem that is at least 15cm long and has several nodes. Remove the leaves from the lower half of the stem and dip the cut end in rooting hormone powder. Plant the stem in a well-draining potting mix, water thoroughly, and cover with a plastic bag to create a humid environment. Keep the soil moist and place the cutting in a bright, indirect light. After a few weeks, new growth should appear, indicating that the cutting has taken root. At this point, the plastic covering can be removed, and the cutting can be transplanted to a larger pot or directly into the garden.
