The plant prefers slightly acidic soil with a pH range of 5.5-6.5. It is recommended to mix perlite or sand with the potting soil to improve drainage and prevent root rot.
Cultivation of Cissus crusei Wild & R.B.Drumm.
Cissus crusei Wild & R.B.Drumm. is a tropical plant that prefers warm and humid conditions. It is best grown in well-draining soil with a slightly acidic pH. The plant requires bright, indirect sunlight for optimal growth.
To cultivate Cissus crusei, start by selecting a well-draining pot or container. Ensure that the soil is moist before planting the cutting, which should be approximately 4-6 inches long. Cover the container with plastic or place it in a clear plastic bag to create a humid atmosphere around the cutting. Additionally, place the pot in warm, indirect sunlight.
Watering Needs
The water requirements of Cissus crusei depend on various factors, including the humidity level, temperature, and soil type. Overwatering or underwatering is harmful to the plant's growth. Therefore, it is essential to water the plant when the soil feels dry to the touch. When the plant is in an active growth phase, it may require more frequent watering.
However, it is crucial to avoid waterlogging or allowing the plant to sit in standing water for an extended period. This can cause root rot and the eventual death of the plant.
Fertilization
Cissus crusei responds positively to regular fertilization. Adding a balanced fertilizer every four to six weeks during the growing season encourages healthy growth and helps the plant produce more foliage. However, during the dormant season, fertilizer application should be limited or stopped altogether.
It is advisable to dilute the fertilizer before applying it to avoid causing damage to the plant's roots. Additionally, always follow the manufacturer's instructions when fertilizing the plant.
Pruning
To maintain the plant's shape and promote bushy growth, pruning is necessary. Prune Cissus crusei regularly by cutting back the straggly stems to the desired shape and size. The ideal time for pruning is during the spring or early summer when the plant is actively growing.
Additionally, removing any dead, diseased, or damaged parts promotes the plant's overall health and prevents the spread of diseases and pests.
Propagation of Cissus crusei Wild & R.B.Drumm.
Cissus crusei Wild & R.B.Drumm. can be propagated through several methods including by seeds, stem cuttings, and air layering.
Propagation by Seeds
Seeds of Cissus crusei can be sown during spring or summer seasons in well-draining soil mixed with organic compost. The seeds can be sown at a depth of 1 cm and watered regularly. It takes about 2-4 weeks for germination and the seedlings can be transplanted to individual pots once they grow two to four leaves.
Propagation by Stem Cuttings
The stem cuttings of Cissus crusei should be about 10-15 cm long and should have two to three nodes. The cuttings can be taken during the growing season and the lower leaves should be stripped. The cuttings should be dipped in rooting hormone and planted in well-draining soil. The soil should be moist and kept in a shady and humid place until the cuttings develop roots. It takes about 4-6 weeks for the roots to develop and the rooted cuttings can be transplanted to individual pots.
Propagation by Air Layering
Air layering is a method of propagation where a stem of the plant is induced to form roots while still attached to the mother plant. It involves wounding a section of a stem and covering it with moistened sphagnum moss and wrapping it with plastic. The moss should be kept moist and roots will start growing from the wounded area after a few weeks. Once the roots are well developed, the new plant can be cut from the mother plant and transplanted to individual pots.
