However, the ideal soil pH for Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz growth is between 6.5 and 7.5. The soil should also be fertile with good water-holding capacity to allow the plant roots access to the nutrients it needs and to prevent wilting in hot weather conditions.
Cultivation Methods
Erucastrum arabicum var. schimperi is a hardy plant that thrives well in a warm and dry climate. It is best to cultivate the plant during the early spring season when the temperatures are mild. The plant can grow well in most types of soil, but it requires well-drained soil with a neutral pH of 6.0 to 7.5. Till the soil to a depth of 10-12 inches before planting.
Watering Needs
The plant does not require a lot of water. However, during the initial growth stage, the plant requires consistent watering to establish itself. Afterward, it only requires occasional watering, especially during long periods of drought. Overwatering can lead to root rot, so it is important to allow the soil to dry out between watering sessions.
Fertilization
When cultivated in fertile soil, the plant does not require a lot of fertilization. However, it is beneficial to add some organic matter or compost to the soil before planting. This adds nutrients to the soil that the plant can easily absorb. It is also recommended to apply a light application of nitrogen fertilizer during the early growth stages.
Pruning
Erucastrum arabicum var. schimperi does not require much pruning. However, removing dead or yellowing leaves can help to stimulate new growth and prevent the plant from wasting energy on dead foliage. It is also advisable to remove any spent flowers to encourage the development of new blooms. Prune the plant in the early spring before new growth begins.
Propagation of Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz
Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz is typically propagated by seeds or cuttings. The plant is easy to propagate and can be done throughout the year.
Seed Propagation
Seeds of Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz can be sown directly into the garden or started indoors. The best time to sow the seeds is during the fall or winter months when temperatures are cool and moist. If sowing indoors, start seeds in early spring. Seeds should be sown shallowly and should be kept moist until they germinate, which typically takes 1-2 weeks.
Seedlings should be transplanted once they have developed their first true leaves. They should be spaced at least 6 inches apart and planted in a well-draining soil. Water regularly until the plant is established.
Cutting Propagation
Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz can also be propagated by cuttings. This method is particularly useful if you want to produce plants with the same characteristics as the parent plant. Take cuttings in the spring or summer months when the plant is actively growing. Use a sharp, sterile pair of shears to take a cutting that is 3-6 inches long. Remove any lower leaves and dip the cut end of the stem in rooting hormone before planting in a well-draining soil. Keep cuttings moist and out of direct sunlight until they have formed roots, which typically takes 2-3 weeks.
Once the cutting has roots, it can be transplanted into a larger pot or into the garden. Water regularly until the plant is established.
Disease and Pest Management for Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz

This plant is prone to certain diseases and pests, which can weaken its growth and affect its yield. Therefore, proper disease and pest management are necessary to ensure the health and vigor of this plant.
Common Diseases
Anthracnose: Anthracnose is a fungal disease that affects the leaves, stems, and seeds of the plant. It causes circular, reddish-brown lesions with distinct borders. To manage anthracnose, remove and destroy infected plant parts, and avoid overhead watering. Fungicides can also be used in severe cases.
Downy Mildew: Downy mildew is a fungal disease that affects the lower leaves of the plant. It causes yellowish patches on the upper surface of the leaves and a white or grayish mold on the lower surface. To manage downy mildew, remove infected leaves immediately, and avoid overhead watering. Fungicides can also be used to control the disease.
Powdery Mildew: Powdery mildew is a fungal disease that affects the leaves, stems, and flowers of the plant. It causes a white, powdery coating on the plant surface. To manage powdery mildew, remove and destroy infected plant parts, and avoid overhead watering. Fungicides can also be used in severe cases.
Common Pests
Aphids: Aphids are small, sap-sucking insects that can deform the leaves of the plant and cause yellowing, stunted growth, and wilting. To manage aphids, spray the plant with a gentle stream of water to dislodge them, or use insecticidal soap or neem oil to control their population.
Cabbage Loopers: Cabbage loopers are green, inchworm-like larvae that can chew holes in the leaves of the plant and cause defoliation. To manage cabbage loopers, handpick the larvae and destroy them or use Bacillus thuringiensis (Bt) to control their population.
Cutworms: Cutworms are dark-colored caterpillars that live in the soil and feed on the stem of the plant, causing it to wilt and eventually die. To manage cutworms, create physical barriers around the plant stem and use insecticidal bait to control their population.
In conclusion, managing disease and pests is important to maintain the health and growth of Erucastrum arabicum Fisch. & C.A.Mey. var. schimperi (Boiss.) O.E.Schulz.
