Light Requirements
Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. typically grows in shaded environments with minimal direct sunlight. These plants thrive under canopy cover within forests, and should not be exposed to excessive amounts of direct sunlight.
Temperature Requirements
The optimal temperature for Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. is between 18°C to 26°C. These plants prefer a consistently warm temperature without excessive fluctuations, so avoiding areas prone to extreme temperature changes is best for their growth and survival.
Soil Requirements
Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. requires well-drained soil that is rich in organic matter. These plants prefer slightly acidic to neutral soils, with a pH range of 5.5 to 7.0. The soil must be moist without becoming waterlogged, which can cause root damage and hinder growth.
Cultivation
Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. is a tropical plant that prefers a warm and humid environment. It can be cultivated in a greenhouse or in a well-lit indoor location.
The plant requires well-draining soil that is high in organic matter. A mix of peat moss, perlite, and vermiculite is ideal for growing this plant.
Propagation can be done by seed or cuttings. Seeds should be sown in moist soil and kept warm until germination, which can take several weeks. Cuttings should be taken from healthy plants and rooted in a rooting hormone before being planted in soil.
Watering Needs
Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. requires consistent moisture but should not be overwatered. Water the plant when the top inch of soil feels dry to the touch, and ensure that the soil does not become waterlogged.
The plant may require more frequent watering during hot and dry weather or in a heated indoor environment.
Fertilization
To promote healthy growth and flowering, fertilize the plant once every two weeks during the growing season with a balanced liquid fertilizer. Dilute the fertilizer to half strength and apply it to damp soil.
Avoid fertilizing during the winter dormant period.
Pruning
Regular pruning is not necessary for Craterispermum brieyi De Wild. var. inquisitorium (Wernham) Verdc. except for the removal of dead or damaged branches. The plant may benefit from occasional pinching to encourage bushy and compact growth.
Pruning should be done during the growing season, and any cuts should be made at a slight angle to prevent water buildup and facilitate healing.
Propagation of Craterispermum brieyi De Wild. var. inquisitorium
Craterispermum brieyi De Wild. var. inquisitorium can be propagated through both seed and vegetative methods.
Seed Propagation
Seeds of Craterispermum brieyi De Wild. var. inquisitorium can be collected from mature fruits and stored in a cool, dry place until planting. The seeds require a pre-treatment of scarification to break their hard coat and enhance germination. This can be achieved by rubbing the seeds against sandpaper or by soaking them in hot water for several hours.
The seeds can be sown in well-draining soil and covered lightly with a layer of sand. The soil should be kept moist but not waterlogged. Germination can take several weeks to months, depending on the conditions.
Vegetative Propagation
Craterispermum brieyi De Wild. var. inquisitorium can also be propagated vegetatively through stem cuttings. The cuttings should be taken from the middle portion of healthy stems and should be approximately 10 cm in length. The leaves on the lower half of the cutting should be removed, and the stem can be treated with a rooting hormone to enhance root development.
The cuttings should be planted in well-draining soil and kept moist but not waterlogged. They should be placed in a shaded area and protected from direct sunlight until they have established roots. Rooting can take several weeks to months, depending on the conditions.
Disease and Pest Management for Craterispermum Brieyi De Wild. var. Inquisitorium (Wernham) Verdc.
