In Pakistan and Iran, it is used for its beneficial effects on the digestive system, such as constipation relief and stomachache prevention. In Saudi Arabia, people use it as a traditional cure for diabetes. The plant extract has also proven antitumor activity, antipyretic activity, and antihyperglycemic activity and can be utilized in the formulated herbal drug. Besides, the plant is also used for landscaping purposes due to its attractive and unique appearance. Moreover, the plant's leaves and stems contain saponins, which are natural detergents that can act as soaps when mixed with water. Therefore, in some regions, the locals use it as a soap substitute for cleansing their clothes.Growth Conditions for Zygophyllum retrofractum Thunb.
Zygophyllum retrofractum Thunb., also known as Persian Silk Plant, is a drought-tolerant and heat-loving succulent plant that thrives in arid and semiarid regions. This plant is native to Asia, specifically China, Japan, Korea, Mongolia, and Russia.
Light
Zygophyllum retrofractum requires full sun exposure to grow and flower. It can tolerate partial shade, but it may affect its growth and flowering. Therefore, it is advisable to plant this species in a sunny location.
Temperature
This plant is well adapted to high temperatures and can tolerate both extremely hot and cold temperatures. The optimal temperature range for its growth is between 20-25 °C, but it can also withstand temperatures as low as -30°C and as high as 60°C.
Soil Requirements
Zygophyllum retrofractum grows best in well-draining, sandy, or gravelly soils. It can also tolerate poor soils, including those with high salinity or alkalinity levels. The pH range for planting this species is between 6.0-8.5. It is crucial to provide good drainage because it is susceptible to root rot under waterlogged conditions.
It is essential to note that this plant has medicinal properties that have been used in traditional medicine for various ailments. Its stems, leaves, and roots contain bioactive compounds that are beneficial to human health, such as anti-inflammatory, antioxidant, and antidiabetic properties.
Cultivation Methods
Zygophyllum retrofractum Thunb., commonly known as the spineless bean-caper, is a shrub that belongs to the family Zygophyllaceae. This plant species is prevalent in arid regions, including sandy and stony deserts.
When cultivating this plant, ensure that you plant it in a well-drained soil type that has a pH between 6.0 and 8.5. Zygophyllum retrofractum thrives best in areas with full sun exposure and a warm climate with temperatures ranging between 20 and 40°C.
Watering Needs
Watering is vital in the cultivation of Zygophyllum retrofractum. The plant requires sufficient water to establish root systems and attain the desired growth rate. For optimal growth, water this plant once every two weeks until it is well-established. However, after the plant attains maturity, it can survive on natural rainfall without the need for supplemental watering.
Fertilization
In addition to regular watering, fertilization plays a crucial role in the growth and development of this plant. Zygophyllum retrofractum requires a balanced fertilizer that supplies essential nutrients such as nitrogen, phosphorus, and potassium. Apply a slow-releasing fertilizer at the beginning of the growing season and repeat it every three months. Avoid over-fertilization as it can lead to the accumulation of salts, thus affecting the soil's pH level.
Pruning
Zygophyllum retrofractum does not require pruning to attain the desired growth. However, pruning can be necessary if the plant is growing in a space-limited area. Pruning should be done in the early spring, before the plant starts to produce new leaves and shoots. Remove the dead branches, diseased or damaged stems, and any suckers that sprout at the base of the plant.
Propagation of Zygophyllum retrofractum Thunb.
Zygophyllum retrofractum Thunb. can be propagated through sexual and asexual means.
Sexual Propagation
The plant can be propagated through seeds. The plant produces a capsule containing four to eight seeds. After the capsule has ripened and dried, the seeds can be collected and sown in a well-drained soil mix. The seeds should be sown at a depth of about 0.5 cm and kept moist until germination. Germination usually takes place within two to three weeks.
Asexual Propagation
Zygophyllum retrofractum Thunb. can also be propagated vegetatively through stem cuttings. The best time to take the cuttings is during the summer when the plant is actively growing. The cuttings should be taken from the tips of non-flowering shoots and should be about 10 cm in length. The lower leaves should be removed, and the cuttings should be dipped in rooting hormone before placing them in a well-draining rooting medium. The plants should be kept in a warm, humid environment until they produce roots, which usually takes about six to eight weeks.
Once the cuttings have rooted, they can be transplanted into individual pots and grown until they are ready to be planted in the ground. It is important to keep the new plants well-watered until they are established.
Disease Management
Zygophyllum retrofractum Thunb. is not typically prone to disease, but certain environmental conditions such as high humidity and poor soil drainage can contribute to fungal infections like root rot and powdery mildew.
To manage fungal infections, it is important to improve soil drainage by amending the soil with sand or gravel and ensuring that the plant is not overwatered. Fungicidal sprays can also be used, but it is best to avoid chemical treatments if possible and opt for natural remedies like neem oil or a mixture of baking soda and water.
Pest Management
While Zygophyllum retrofractum Thunb. can generally tolerate pests, there are a few common insects that may cause damage to the plant. These include whiteflies, spider mites, and mealybugs.
To manage pests, a first line of defense is to regularly inspect plants and remove any visible pests by hand. A strong spray of water can also be used to dislodge pests like spider mites. For heavy infestations, natural pesticides like insecticidal soap and neem oil can be used. It is important to follow instructions carefully when using any kind of pesticide and use them sparingly to avoid harming beneficial insects and pollinators.
