Growth Conditions of Athanasia calva Hutch.
Athanasia calva Hutch., commonly known as the Kalahari Crown, has very specific growth conditions that should be met to ensure its proper growth and development. The following are the recommended growth conditions for Athanasia calva Hutch.:
Light Requirements
Athanasia calva Hutch. requires full sunlight exposure to thrive. The plant should be placed in an area where it can get at least 6 hours of direct sunlight daily. Lack of enough sunlight may result in stunted growth and a weak immune system.
Temperature Requirements
Athanasia calva Hutch. is a heat-loving plant that prefers warm temperatures. It thrives well in temperatures ranging from 20 to 30°C. Temperatures below 15°C can cause damage to the plant's leaves and slow down its growth. To ensure optimal growth, avoid exposing the plant to chilly and frosty weather conditions.
Soil Requirements
Athanasia calva Hutch. thrives in soils that are well-drained and rich in nutrients. The plant prefers sandy soil with a loamy texture. The pH of the soil should be between 6.0 and 7.5. The plant is also tolerant to salty soils but prefers slightly acidic to neutral soils.
Athanasia calva Hutch. is drought-tolerant but requires regular watering during the growing season. Overwatering should be avoided as it can lead to root rot and other related problems. Applying organic fertilizers during the growing season can boost the plant's growth and overall health.
Cultivation
Athanasia calva Hutch. is a perennial plant that's native to Tanzania. To cultivate it, you should start by picking a good spot with sufficient sunlight and well-draining soil as the ideal growing conditions. You can plant the seeds directly in the soil during the summer months when temperatures are warm. Ensure that you cover the seeds with a thin layer of soil, and water them immediately after planting. The germination period is usually around seven to ten days, and the plant will continue growing throughout the year.
Watering
You should water the Athanasia calva Hutch. plant frequently during the growing season, particularly when temperatures are high. Ensure that you provide enough water to the plant without soaking the soil. This plant is drought-resistant, although it can die back considerably during prolonged drought periods. Therefore, ensure that you maintain an adequate level of soil moisture. However, during the winter or dormant period, limit watering significantly.
Fertilization
Athanasia calva Hutch. plant prefers growing in soil that's rich in organic material. Adding organic fertilizers like aged manure can help establish healthy growth habits. You can also use a balanced, slow-release fertilizer during the growing season to provide the necessary nutrients that your plant requires.
Pruning
Athanasia calva Hutch. does not require significant pruning, although deadheading spent flowers may encourage additional blooming. Additionally, cutting the plant back to a third of its initial size in the late summer or early autumn encourages new growth in the coming year. You can also trim any broken, or dead branches to maintain the plant's shape and health.
Propagation of Athanasia calva Hutch.
Athanasia calva Hutch., commonly known as Wolkbreuk, is a perennial herb that belongs to the Asteraceae family. Propagation of Athanasia calva Hutch. can be done through various methods which include:
Seed Propagation
Seed propagation is the most common method of propagating Athanasia calva Hutch. This method involves collecting mature seeds from a healthy and mature plant. The seeds should be collected when the plant begins to dry out and drop them. Once the seeds are collected, they should be cleaned and treated to remove any pathogens that may be present. Seed treatment can be done by soaking the seeds in a fungicide solution for up to 24 hours.
The treated seeds should then be sown in seed trays or pots. The soil mix should be well-draining and should contain equal parts of compost, sand, and garden soil. The seeds should be lightly covered with soil and kept moist until germination occurs. Germination should take between 14 to 21 days.
Vegetative Propagation
Varieties of Athanasia calva Hutch. can also be propagated vegetatively. This method involves cutting a stem or leaf from a mature plant and replanting it to form a new plant. This method is commonly used to propagate Athanasia calva Hutch. cultivars with desirable characteristics.
The cutting should be taken from a healthy plant that is not producing flowers. The cutting should be 10-15cm long and should contain at least one node. The cutting should be dipped in rooting hormone powder to enhance root development. The cutting should be planted in a well-draining soil mix and kept moist until roots appear.
Division Propagation
Division propagation is another method of propagating Athanasia calva Hutch. This method involves dividing a mature plant into smaller sections and replanting them to form new plants. This method is recommended for older plants that may have lost their vigor or become overcrowded.
The plant should be dug up and carefully divided into smaller sections, each containing a healthy root system. Each section should be planted in a well-draining soil mixture and watered thoroughly until established.
Propagation of Athanasia calva Hutch. can be done using any of these three methods. However, seed propagation is the most preferred method since it offers a higher success rate and is less labor-intensive.
