Temperature Requirements
The Combretum imberbe is heat-tolerant and can withstand high temperatures of up to 45°C. It grows best in warm regions with an average temperature of 25-30°C. However, it can tolerate moderate cold temperatures of up to -5°C during the dormant season.
Soil Requirements
This plant is highly adaptable and can grow in different types of soil. However, it thrives well in well-drained sandy or loamy soils with a pH range of 6.0-8.0. The soil texture should be moist but not waterlogged as the plant is susceptible to root rot in waterlogged soil.
It is essential to ensure that the plant receives sufficient water during the early stages of growth, but once established, it can tolerate drought conditions for short periods.
Overall, the Combretum imberbe Wawra var. truncatum (M.A.Lawson) Burtt Davy is a robust and highly adaptable plant that can flourish in different growing conditions, provided that it receives adequate sunlight, moderate temperatures, and well-drained soil.
Cultivation Method
The Combretum imberbe Wawra var. truncatum (M.A.Lawson) Burtt Davy is a drought-resistant plant that thrives in well-draining soil. The plant needs a warm to hot climate for optimal growth and should be planted in full sun, although it can grow well in partial shade.
The plant is typically propagated via seeds, which should be sown in a nursery before being transplanted to the main field. It is recommended to add organic matter to the soil before planting, such as compost or well-rotted manure, to improve soil fertility and water retention.
Watering Needs
The Combretum imberbe Wawra var. truncatum (M.A.Lawson) Burtt Davy is a drought-resistant plant and does not require a lot of water. It is essential to water the plant regularly during its initial growth period, typically during the first year after planting. After that, the plant can survive on rainfall and occasional watering during extended dry periods.
Fertilization
The Combretum imberbe Wawra var. truncatum (M.A.Lawson) Burtt Davy is not a heavy feeder and does not require a lot of fertilization. Fertilizers containing nitrogen and phosphorus can help improve the plant's growth, but excess application can lead to too much vegetative growth and less flowering. It is recommended to apply fertilizer during the early growth period and only if the soil lacks necessary nutrients.
Pruning
The Combretum imberbe Wawra var. truncatum (M.A.Lawson) Burtt Davy does not require frequent pruning. Prune the plant only to remove damaged or dead wood. Additionally, remove any suckers that grow from the base of the plant to maintain its shape and size. Pruning should be done during the plant's dormant period.
Propagation of Combretum imberbe Wawra var. truncatum
Combretum imberbe Wawra var. truncatum can be propagated with seeds or cuttings.
Propagation from Seeds
Fresh seeds should be collected from mature fruits and soaked in water for 24 hours to soften the seed coat. The softened seeds are then sowed in well-draining soil and covered lightly with soil. They should be kept moist and in a warm location with partial shade until germination occurs. Germination can take anywhere from 4-8 weeks.
Propagation from Cuttings
Combretum imberbe Wawra var. truncatum can be propagated from semi-hardwood cuttings taken from actively growing shoots. Cuttings should be taken from healthy parent plants, and the leaves should be removed from the bottom half of the cutting. The cuttings should be treated with rooting hormone and planted in well-draining soil. The cuttings should be kept moist and in a warm location with partial shade until new growth appears.
Propagation by cuttings may be slower than propagation by seeds, however, it has the advantage of producing clones that are identical to the parent plant.
