Appearance
The plant has a prostrate or ascending growth habit and grows to a height of 10-80 cm. It has a taproot system with many lateral roots. The stem is woody and branches multiple times near the base. The leaves are opposite, pinnate, and glabrous. The leaflets are elliptical to ovate and have a smooth margin. The plant produces small, yellow flowers that are about 1 cm in diameter. The fruit is a woody, 5-angled capsule with sharp spines and contains several seeds.
Uses
Tribulus alatus Delile var. monodi Maire has been used in traditional medicine for its diuretic, antiseptic, and aphrodisiac properties. The plant is also used as a natural remedy for various ailments such as hypertension, urinary tract infections, and inflammatory diseases. The seeds of T. alatus are used as an ingredient in traditional dishes in North African and Middle Eastern cuisines. In addition, the plant has been studied for its potential use in the treatment of cancer and as a natural insecticide.
Light Requirements
Tribulus alatus Delile var. monodi Maire thrives in full sunlight exposure. The plant requires a minimum of 6 hours of direct sunlight per day to grow fully. Low light conditions or shade would reduce its growth rate and overall vigor. Therefore, it is essential to plant the species in a location with maximum sunlight exposure.
Temperature Requirements
The plant can tolerate a wide range of temperatures, but it grows best in warm temperatures between 20°C to 35°C. However, the species can withstand temperatures as high as 50°C or as low as -4°C. If grown in temperatures outside its optimum range, growth rate and germination success reduce. It is important to note that temperature fluctuations or extreme temperature changes could harm the plant, leading to stunted growth or even death.
Soil Requirements
Tribulus alatus Delile var. monodi Maire typically thrives in sandy or loamy soil that is well-drained, slightly acidic and has moderate fertility. The species can tolerate a wide range of soil pH, from 5.5 to 7.5. However, poorly drained soils or soils with high clay content can lead to waterlogging and root rot, leading to the plant's death. It is best to plant the species in a well-drained soil with occasional fertilization to provide the necessary nutrients and ensure optimal growth rate.
Cultivation methods
Tribulus alatus Delile var. monodi Maire thrives well in well-draining soil with a neutral pH level. The plant is drought-tolerant and prefers a warm and sunny environment for optimal growth. It is best grown through direct sowing of seeds outdoors after the danger of frost has passed. Alternatively, you may start indoors in pots and transplant once the seedlings are at least four inches tall.
Watering needs
As a drought-tolerant plant, Tribulus alatus Delile var. monodi Maire requires minimal watering. Water the plant deeply every two to three weeks in the absence of rainfall. Reduce watering during the off-season when the plant is dormant.
Fertilization
Tribulus alatus Delile var. monodi Maire requires minimal fertilization. A slow-release fertilizer applied once during the beginning of the growing season is sufficient to provide the necessary nutrients for the plant to grow optimally.
Pruning
Tribulus alatus Delile var. monodi Maire does not require extensive pruning. Remove any dead or diseased leaves and stems as necessary. To encourage bushier growth, pinch the growing tips of the plant when it is young to stimulate lateral branches.
Propagation of Tribulus alatus Delile var. monodi Maire
Tribulus alatus Delile var. monodi Maire, commonly known as the puncture vine or caltrop, is a hardy shrub that is native to the Mediterranean region. It has a bitter taste and has been used for medicinal purposes for centuries. Propagation of this plant is relatively easy, and it can be done through several methods such as seeds, softwood cuttings, and division.
Propagation by Seeds
Propagation by seeds is the most common and effective way to grow Tribulus alatus Delile var. monodi Maire. Collect the ripe seedpods from the plant and let them dry in a warm, dry place. Sow the seeds in a seed tray or small pots filled with well-draining soil, and cover them with a thin layer of soil. Water the seeds gently and keep them in a warm, sunny spot. In about two to three weeks, the seeds will germinate. Once the seedlings are large enough, transplant them into larger pots or into the ground.
Propagation by Softwood Cuttings
Tribulus alatus Delile var. monodi Maire can also be propagated by softwood cuttings. Take a softwood cutting from the plant during the growing season, making sure to avoid any flowers or buds. Remove the leaves from the lower part of the cutting, leaving a few leaves at the top. Dip the cutting in rooting hormone and plant it in a pot filled with well-draining soil. Water the cutting and place it in a warm, sunny spot. In about one to two months, the cutting will form roots. Once the roots have formed, transplant the new plant into a larger pot or into the ground.
Propagation by Division
Tribulus alatus Delile var. monodi Maire can also be propagated by division. This method is best done in the springtime. Dig up the plant and carefully separate the roots into several sections, making sure that each section has some roots and shoots. Replant each section in a pot or in the ground, and water it well. Keep the new plants in a warm, sunny spot and make sure to water them regularly until they are established.
Disease and Pest Management for Tribulus alatus Delile var. monodi Maire
Tribulus alatus Delile var. monodi Maire, a popular medicinal plant, is susceptible to different diseases and pests, which can affect its growth and productivity. Here are some of the common diseases and pests that affect it and ways to manage them:
Diseases
1. Bacterial diseases: Bacterial diseases such as leaf spot, blight, and canker are common in Tribulus alatus Delile var. monodi Maire. These diseases are characterized by a watery lesion or a yellowish-colored area on the leaves. They can be prevented by the application of copper-based fungicides or by removing the affected parts of the plant.
2. Fungal diseases: Fungal diseases such as powdery mildew and rust are common in Tribulus alatus Delile var. monodi Maire.

Pests
1. Aphids: Aphids are common pests that affect the growth of Tribulus alatus Delile var. monodi Maire. These pests suck the sap from the leaves, resulting in stunted growth and yellowing of the leaves. They can be prevented by spraying the plant with neem oil or insecticidal soap.
2. Spider mites: Spider mites are another pest that affects Tribulus alatus Delile var. monodi Maire. These pests cause the leaves to become yellow and dry, resulting in stunted growth. They can be prevented by spraying the plant with water or by using a miticide.
3. Whiteflies: Whiteflies are also common pests that affect Tribulus alatus Delile var. monodi Maire. These pests feed on the sap of the leaves, causing them to turn yellow and fall off. They can be prevented by the application of insecticidal soap or by removing affected leaves.
In conclusion, effective disease and pest management is vital for the successful cultivation of Tribulus alatus Delile var. monodi Maire. A combination of cultural, biological, and chemical measures can be used to control the different diseases and pests that affect the plant and ensure its optimal growth and productivity.
