Propagation of Arctotis Rogersii
Arctotis rogersii, commonly known as Rogers' Arctotis, is a beautiful, fast-growing plant with eye-catching flowers. The plant is native to South Africa and is mostly grown in home gardens, conservatories, or as a border plant. It can be propagated through different methods as described below.
Propagation through Seeds
The easiest and most common method of propagating Arctotis rogersii is by using seeds. The seeds should be sown in a well-draining potting mix and placed in a well-lit area at a temperature of around 18-25°C. It is essential to keep the potting mix moist but not waterlogged. The seeds should germinate within two to three weeks, and once the seedlings have reached a size of approximately 6-8 cm, they can be transplanted to larger containers or directly into the garden beds.
Division
Another way of propagating Arctotis rogersii is by division. It involves separating an established plant into several portions, each of which can grow independently. To begin the process, dig up the plant and carefully separate its roots into smaller chunks using a sharp and clean knife. Each portion that has roots should have a few shoots above the soil surface. The divided plants should then be immediately replanted in well-draining soil in separate containers or directly into the garden beds.
Cuttings
Arctotis rogersii can also be propagated using stem cuttings. The best time to take stem cuttings is during the spring/summer season. Choose a strong stem with no flowers or buds, and cut a section that is around 7-10 cm in length. Remove any leaves from the bottom part of the cutting, leaving only two or three at the top. Dip the cut end into rooting hormone powder and place it in a well-drained rooting medium. Keep the potting mix evenly moist and place the cutting in a shaded area until roots develop. Once the roots are established, transplant the plants into individual containers with fresh potting mix or directly into the garden beds.
Overall, Arctotis rogersii is an easy-to-grow plant that can be propagated through seeds, division, and stem cuttings. By following these methods, you can easily increase your stock of this beautiful plant.
Disease and Pest Management for Arctotis Rogersii (Benson) M.C.Johnst.
