Fertilizer requirements
Erlangea calycina S.Moore is a heavy feeder and requires regular fertilization. A balanced, water-soluble fertilizer should be applied every two weeks during the growing season. Avoid over-fertilizing as it may damage the plant.
Cultivation methods
Erlangea calycina S.Moore is a hardy perennial plant that requires full sun to grow. It prefers well-drained soil and can tolerate a wide range of soil types. The plant grows up to 2.5 meters in height and can spread up to 1.5 meters across, so it requires ample space to grow. Propagation of the plant can be done through seeds or cuttings.
Watering needs
The plant requires moderate watering during the growing season, especially during hot spells. However, it is essential to avoid overwatering as it can lead to waterlogging and root rot. Water the plant once a week or whenever the soil feels dry to the touch. Reduce watering during the dormant season to prevent the plant from suffering from moisture stress.
Fertilization
Fertilization of Erlangea calycina S.Moore should be done during the growing season. Use a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Fertilize the plant once a month or as required based on soil conditions. Avoid over-fertilization as it can lead to excessive foliage growth at the expense of flowers.
Pruning
Pruning of the plant should be done after the flowering season. Cut back the stems to about half their height to encourage lateral branching and promote bushy growth. Prune out any dead or diseased wood to prevent the spread of disease and to keep the plant healthy. During the growing season, pinch back the tips to promote lateral branching and bushy growth.
Propagation of Erlangea calycina S.Moore
Erlangea calycina S.Moore is a perennial plant that belongs to the family of Asteraceae. It is native to southern Africa and is commonly found growing in grasslands and along roadsides. Propagation of this plant can be done by different methods, including:
Seed propagation
The most common method of propagating Erlangea calycina is through seeds. Seeds can be obtained by collecting the mature fruits of the plant. After collecting, the seeds should be cleaned and dried before storage. To initiate germination, the seeds should be sown in a well-draining soil mix and kept moist. It is advisable to sow the seeds during spring or early summer when the temperatures are warm.
Cutting propagation
Propagation of Erlangea calycina can also be done through stem cuttings. The best time to take cuttings is during the growing season when the plants are actively growing. Cuttings should be taken from healthy plants and should be at least 10cm long. The cuttings should then be dipped in rooting hormone before planting in a well-draining soil mix. It is advisable to keep the cuttings moist and in a shaded area until they form roots.
Division propagation
Propagation of Erlangea calycina can also be done through division. This method is mostly done with mature plants that have formed clumps. To divide the plants, carefully dig up the clump and separate the individual plants. Each plant should have a well-developed root system. The divided plants should then be planted in well-draining soil and should be kept moist until they become established.
Conclusion
Erlangea calycina S.Moore is an attractive plant that can easily be propagated through seeds, cuttings, and division. Propagation of this plant requires patience and care, but the rewards are worth the effort. Choose the propagation method that works best for you and enjoy growing this beautiful plant.
