Temperature Requirements
The ideal temperature range for growth and development of Crossandra subacaulis C.B.Clarke is between 18°C to 30°C. It cannot survive in areas where temperatures dip below 10°C or exceed 35°C. It is important to keep the plant away from cold drafts during winter and direct exposure to heat sources in summer.
Soil Requirements
Crossandra subacaulis C.B.Clarke prefers well-draining soil that retains moisture but is not waterlogged. A pH range between 5.5 to 6.5 is ideal. The soil should be rich in organic matter, providing the necessary nutrients for the plant’s healthy growth. It is recommended to incorporate perlite or sand to improve drainage, especially during the wet season when the soil may become waterlogged.
Cultivation
Crossandra subacaulis C.B.Clarke is a tropical perennial plant that requires temperatures between 60°F and 85°F to grow best. It thrives in well-drained soils that are slightly acidic in nature. The plant prefers bright but indirect light and can be grown indoors as well as outdoors in suitable conditions.
Watering Needs
The plant requires regular watering to keep the soil moist. The frequency of watering can be reduced during winter or when the weather is cooler. Overwatering should be avoided, as it can lead to root rot and other fungal diseases.
Fertilization
Crossandra subacaulis C.B.Clarke requires regular fertilization for healthy growth and bloom. A suitable liquid fertilizer can be applied once every two weeks during the growing season. The fertilizer should be applied at half strength, as excessive fertilization can lead to foliage burn and other problems.
Pruning
Crossandra subacaulis C.B.Clarke may require pruning to remove dead or damaged leaves and stems. Pruning can also help to shape the plant and promote new growth. It is recommended to prune the plant after the blooming season to avoid removing the buds that may develop soon after.
Propagation of Crossandra subacaulis C.B.Clarke
Crossandra subacaulis C.B.Clarke, also known as the dwarf firecracker plant, is a small shrub that produces clusters of orange-red flowers. Propagation of this plant can be done through several methods including seed germination, stem cuttings, and division.
Seed Germination
Propagation of Crossandra subacaulis by seed is relatively easy. Seeds can be collected from fully matured flowers and sown into a well-prepared seedbed. The seeds should be sown thinly and covered with a thin layer of soil. The seedlings can be transplanted to individual pots after a few weeks of growth.
Stem Cuttings
Propagation of Crossandra subacaulis by stem cuttings is the most common method. The stem cuttings should be taken from mature plants. The cuttings should be about 4-6 inches in length. Remove the leaves from the lower 2 inches of the cutting and dip the cut end in rooting hormone. Insert the cutting into a well-prepared potting mix and keep it moist. The cuttings will start to root within four to six weeks and can be transplanted to individual pots.
Division
Propagation of Crossandra subacaulis by division is done by dividing the plant into smaller sections. This method is best done when the plant is mature. Carefully lift the plant from the soil and gently separate the plant into smaller sections with a sharp knife. Each section should have a good clump of roots. Transplant the sections into individual pots and keep the soil moist until new growth appears.
