Light Requirements
The plant Cleome kalachariensis (Schinz) Gilg & Gilg-Ben. thrives best in full sunlight. It requires at least six hours of direct sunlight per day to grow optimally. It can withstand partial shade, but the blooms tend to be fewer and smaller than those grown in full sunlight.
Temperature Requirements
The ideal temperature range for the growth and development of Cleome kalachariensis (Schinz) Gilg & Gilg-Ben. is between 20°C to 30°C. The plant can tolerate high temperatures up to 40°C, but it can get easily stressed if exposed to extremely low temperature. The plant does not tolerate frost and requires protection during the winter season in colder regions.
Soil Requirements
Cleome kalachariensis (Schinz) Gilg & Gilg-Ben. grows best in well-drained loamy soils with a pH range of 6.0 to 7.5. The soil texture should be light and airy to allow for proper root development. Heavy clay soils can be unsuitable for this plant as they retain water and can cause root rot. The plant requires moderate watering as it cannot tolerate drought conditions. Addition of organic matter to the soil can help improve soil fertility and aeration.
Cultivation
Cleome kalachariensis can be grown either from seeds or stem cuttings. It requires well-drained soil and a sunny location to thrive. The plant can withstand high temperatures but cannot tolerate frost. It is recommended to plant the seeds at least 6-8 weeks before the last expected frost. If grown indoors, use grow lights for optimal growth.
Watering Needs
Cleome kalachariensis requires moderate watering during the growing season. Do not allow the soil to dry out completely, but also avoid overwatering. Overwatering can cause root rot and damage the plant. Water the plant deeply once or twice a week, depending on the weather conditions and soil type.
Fertilization
Cleome kalachariensis requires regular fertilization to promote healthy growth and blooming. Use a balanced fertilizer with equal parts nitrogen, phosphorus, and potassium. Apply the fertilizer every 4-6 weeks during the growing season. Avoid over-fertilization, as it can cause the plant to produce more foliage than blossoms.
Pruning
Cleome kalachariensis does not require pruning. However, if the plant becomes too leggy or tall, you can pinch back the tip of the stems to encourage bushier growth. Deadheading spent flowers can also promote more blooming. Remove any damaged or diseased leaves and stems promptly to prevent the spread of infection.
Propagation of Cleome kalachariensis (Schinz) Gilg & Gilg-Ben.
Cleome kalachariensis (Schinz) Gilg & Gilg-Ben., commonly known as the Kalahari spider flower, is a beautiful and exotic perennial plant that is native to southern Africa. Propagation of this plant is relatively easy and can be achieved by using the following methods:
Seed Propagation
The most common and easiest way to propagate Cleome kalachariensis is through seed propagation. Seeds of this plant can be directly sown outdoors in the spring or fall. Before sowing the seeds, ensure the soil is well-draining and mildly fertile. Sow the seeds at a depth of 2-3mm, water them well, and cover them with a thin layer of soil. The seeds will germinate within 7-21 days and will develop into small seedlings in a few weeks.
Cuttings Propagation
Cleome kalachariensis can also be propagated using cuttings. However, it is important to note that this method has a lower success rate than seed propagation. Take stem cuttings from a healthy plant, ensuring that the cuttings are 3-4 inches long. Remove the leaves from the lower half of the cutting, dip the cut end in rooting hormone, and place the cutting in a well-draining potting mix. Water the cutting regularly and cover it with plastic to create a humid environment. Roots will start to form in 3-4 weeks.
Division Propagation
This propagation method involves dividing the roots of an established plant. Dig up the plant and gently separate the roots into two or more sections, ensuring that each section has a good amount of roots and foliage. Then, plant each division into its own container with well-draining soil and water it thoroughly. Keep the newly transplanted divisions in a shady location for a few days and gradually move them to a sunnier location.
Propagation of Cleome kalachariensis can be a fun and rewarding experience, and by utilizing these methods, anyone can enjoy its beauty in their garden or home.
