It thrives in well-drained soils, full sun, and moderate temperatures, and can tolerate drought conditions. The best cultivation method for this plant is through seed propagation.
To propagate by seed, it is advisable to sow the seeds in early spring when the soil is warm. Before planting, ensure the soil is well prepared by tilling, and removing all weeds and debris. Sow the seeds at a depth of 2-3 cm apart and cover them evenly with soil. Water the seeds well and maintain adequate moisture levels during the germination period.
Watering Needs for Medicago arabica (L.) Huds. ssp. inermis Ricker
Medicago arabica (L.) Huds. ssp. inermis Ricker is drought resistant, but watering is still necessary to ensure healthy growth. Watering frequency will depend on the prevailing weather conditions and the soil type. Sandy soil requires more frequent watering than clay soil, which retains moisture for longer periods.
For newly planted seedlings, water regularly and maintain evenly moist soil. As the plants mature, reduce watering, and allow the soil to dry slightly between watering sessions. Avoid overwatering as it can lead to root rot and other fungal diseases.
Fertilization of Medicago arabica (L.) Huds. ssp. inermis Ricker
To maintain healthy plant growth, fertilization is essential. Apply nitrogen-rich fertilizers in early spring, preferably organic fertilizers, to ensure slow and steady growth. Quick-release fertilizers can lead to rapid growth, which leaves the plant vulnerable to pests and diseases.
Apply fertilizers according to the manufacturer's instructions, and avoid over-fertilization. Over-fertilization can lead to excessive foliage growth, which reduces plant vigor and can lead to an increased incidence of pests and diseases.
Pruning of Medicago arabica (L.) Huds. ssp. inermis Ricker
Pruning medick is not a necessity, but it can help control the plant's growth and maintain its shape. Pruning is best done in late winter or early spring, just before the plant starts actively growing.
Use clean, sharp pruning shears to remove dead or damaged branches and stems. Remove all suckers growing from the base of the plant to ensure proper air circulation and light penetration. Pruning can also be done to remove any overgrown branches, but avoid removing more than a third of the plant to avoid stunting growth.
