Temperature
Cryptosepalum exfoliatum De Wild. subsp. suffruticans grows best in a warm, tropical climate. It can tolerate low temperatures and mild frost, but prolonged exposure to freezing temperatures may damage the plant. Ideally, temperatures should range between 20 to 30°C (68 to 86°F).
Soil
The plant prefers well-draining, acidic soil with a pH range of 5.5 to 6.5. The soil should be enriched with organic matter, such as compost or peat moss, to improve its water retention and fertility. Cryptosepalum exfoliatum De Wild. subsp. suffruticans can also grow in poor soils, but it will require frequent watering and fertilization.
Cultivation methods
Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan, commonly known as African cherry, is an evergreen shrub that can grow up to 4 meters tall. It is native to West and Central Africa and is commonly grown as an ornamental plant. For optimal growth, this plant requires full sun to partial shade and well-drained soil. It is best to plant this shrub during the rainy season to help establish its roots.
Watering needs
Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan requires regular watering to thrive. This plant requires moist soil but can be susceptible to root rot if overwatered. It is best to water this plant when the top layer of soil feels dry to the touch. During hot and dry weather conditions, a more frequent watering schedule may be necessary.
Fertilization
To promote healthy growth and flowering, it is important to fertilize Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan. Fertilization should be done once a month during the growing season using a balanced fertilizer. Be careful not to over-fertilize this plant as it can lead to excessive growth and weak branching.
Pruning
Regular pruning can help maintain the shape and size of Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan. Pruning should be done in the early spring before new growth emerges. It is best to remove dead or damaged branches, crossing branches, and any other growth that detracts from the overall shape and appearance of the plant. Avoid removing more than one-third of the plant's overall growth at any one time.
Propagation of Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan
Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan can be propagated from both seeds and cuttings. However, propagation from cuttings is more commonly practiced because seeds have a low germination rate.
Propagation from Cuttings
To propagate Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan from cuttings, select healthy, mature stems during the growing season. Cuttings should be around 10-15 cm long and have at least two nodes.
Remove the bottom leaves and dip the cut end in a rooting hormone powder. Plant the cuttings in a well-draining soil mix and water thoroughly. Cover the plant with a clear plastic bag to increase humidity and reduce moisture loss. Keep the plant in a bright, warm location, out of direct sunlight. Roots should develop in 4-6 weeks.
Propagation from Seeds
Seeds of Cryptosepalum exfoliatum De Wild. subsp. suffruticans (P.A.Duvign.) P.A.Duvign. & Brenan have a hard seed coat, which needs to be scarified for germination. This involves breaking, scratching, or nicking the seed coat to expose the inner seed.
To scarify the seeds, soak them in hot water for several hours or use sandpaper to scratch the seed coat. Plant the seeds in a well-draining soil mix and cover lightly with soil. Water the soil thoroughly and keep it moist. Germination should occur in 4-8 weeks.
Propagation from seeds is more unpredictable than from cuttings, as the seedling may not be true to the parent plant.
