The plant can be propagated by seeds or cuttings, with cuttings being the most common and effective method. Seeds should be sown in a seed bed and kept moist until germination.
Watering needs for Jacquinia berteroi Spreng.
The Jacquinia berteroi Spreng. plant requires moderate watering and does not tolerate drought or waterlogging. Watering should be done thoroughly but not excessively. The soil should be allowed to dry out slightly before watering again. Once established, the plant can tolerate short periods of drought.

Propagation of Jacquinia berteroi Spreng.
Jacquinia berteroi Spreng. can be propagated through different methods like cuttings, seeds, and grafting.
Propagation through cuttings
Propagation through cuttings is the easiest and most commonly used method for Jacquinia berteroi. Cuttings can be collected from healthy and vigorous shoots during the growing season. The cuttings should be 6 to 8 inches long and should have at least 3 to 4 nodes. Remove the leaves from the lower part of the cutting and dip the end of the cutting in a rooting hormone. Place the cutting in a well-drained potting mix and water it regularly. Keep the pot in a warm and humid place and within a few weeks, roots will start to form. Once the roots are well established, the cutting can be transplanted in a larger pot or in the garden.
Propagation through seeds
Propagation through seeds is another method to propagate Jacquinia berteroi. The seeds should be collected from ripe fruits and should be sown as soon as possible. Clean the seeds and soak them in water for a few hours to soften the seed coat. Sow the seeds in a well-drained potting mix, cover them lightly with soil, and water them. Keep the pot in a warm and humid place and seeds will germinate within 2 to 4 weeks. Once the seedlings are big enough, they can be transplanted in a larger pot or in the garden.
Propagation through grafting
Propagation through grafting can also be done for Jacquinia berteroi. This method is usually used to propagate cultivars and selected varieties. Grafting involves joining a selected scion with a compatible rootstock. The scion should be collected during the growing season from healthy and vigorous shoots. The rootstock should be selected based on its compatibility with the scion. The scion and the rootstock should be joined by making a slanted cut on both so that they fit together perfectly. Secure the two parts tightly with grafting tape and keep the plant in a warm and humid place until the grafts have united. Once the graft has taken, the plant can be transplanted in a pot or in the garden.
