Propagation of Diplotaxis acris (Forssk.) Boiss. var. tibestica Chevassut & Quézel
Propagation of Diplotaxis acris (Forssk.) Boiss. var. tibestica Chevassut & Quézel can be done through various methods. It can be propagated through seeds or by vegetative means such as cuttings and division. Understanding the propagation methods will help in the successful growth and propagation of these plants.
Propagation through Seeds
Diplotaxis acris (Forssk.) Boiss. var. tibestica Chevassut & Quézel can be propagated through seeds. The seeds can be collected from the plant when they are ripe and sown immediately. The seeds can be sown in pots or trays filled with a well-draining soil mix. The seeds should be covered lightly with soil and watered regularly. The pots or trays should be kept in a warm and sunny location for the seeds to germinate. Once the seedlings have emerged, they should be thinned out to ensure proper growth and development.
Propagation through Cuttings
Diplotaxis acris (Forssk.) Boiss. var. tibestica Chevassut & Quézel can be propagated through cuttings. The cuttings can be taken from healthy and mature plants during the growing season. The cutting should be about 10-15 cm long and have at least two or three nodes. The leaves on the lower half of the cutting should be removed, and the cutting should be dipped in rooting hormone powder. The cutting should be planted in a well-draining soil mix and kept in a warm and humid environment till it develops roots. Once roots have developed, the cutting can be transplanted to a larger pot or directly in the garden.
Propagation through Division
Diplotaxis acris (Forssk.) Boiss. var. tibestica Chevassut & Quézel can also be propagated through division. This method involves dividing the plant into smaller sections and replanting them. The plant should be carefully dug up, and the root ball should be divided into smaller sections using a sharp knife or a garden fork. Each section should have a good amount of roots and leaves. The divided sections can be replanted in a well-draining soil mix and watered regularly. This method is best done during the early spring.
