The plant produces flowers that are greenish-yellow and deeply divided, growing in clusters that can reach up to 20 cm in length. The fruit, known as Hog Plum, is a small drupe that measures between 1 and 2 cm in diameter, with a yellowish-green color when ripe. The fruit has a sour taste and is covered with a thin, velvety skin.
Light requirements
The plant Pacouria petersiana var. schweinfurthiana typically grows in understory conditions, meaning it thrives in shaded areas with dappled light. Direct sunlight can be too intense for this plant, causing sunscald and stunted growth. Indoors, it can be placed near a north-facing window or away from direct sunlight.
Temperature requirements
Pacouria petersiana var. schweinfurthiana grows best in warm to hot temperatures, typically between 20-32°C (68-90°F). It can tolerate cooler temperatures, but growth will slow and the plant may become dormant during the winter months. It is important to keep the plant away from draughts and cold windows.
Soil requirements
Well-draining soil is crucial for the growth of Pacouria petersiana var. schweinfurthiana. It prefers a rich, sandy soil that is slightly acidic with a pH of 5.5-6.5. The plant requires regular watering, but soil should be allowed to dry out slightly between watering to prevent root rot.
Cultivation Methods
Pacouria petersiana (Klotzsch) S.Moore var. schweinfurthiana (Hallier f.) S.Moore can be cultivated both indoors and outdoors. For indoor cultivation, the plant needs to be placed near a window that receives bright but indirect sunlight. For outdoor cultivation, it is recommended to grow the plant in a shaded area or under a tree canopy.
Watering Needs
The plant should be watered regularly, but you should not overwater it. Make sure that the pot has proper drainage holes to prevent the plant from becoming waterlogged. A good rule of thumb is to allow the top inch of soil to dry out before watering the plant again.
Fertilization
Fertilize the plant during the growing season using a balanced, water-soluble fertilizer that is rich in nitrogen and phosphorus. It is recommended to fertilize the plant every two weeks during the growing season and once a month during winter.
Pruning
Prune the plant to maintain its shape and size. Pruning should be done during the growing season. Remove any dead or yellow leaves to encourage healthy growth. Prune back any overgrown branches to promote bushier growth. You can also pinch back the tips of the stems to promote branching.
Propagation of Pacouria petersiana var. schweinfurthiana
Pacouria petersiana var. schweinfurthiana can be propagated through various methods, including seeds, cutting, and division. These methods are discussed below:
Propagation by Seeds
The seeds of Pacouria petersiana var. schweinfurthiana can be obtained from the mature fruit of the plant. Once collected, the seeds should be cleaned and sown in a good quality potting mix. The potting mix should be kept moist and placed in a warm, bright location, with temperatures above 20°C, for germination to occur. Germination can take anywhere from 1 to 3 months.
Propagation by Cuttings
Cuttings of Pacouria petersiana var. schweinfurthiana can be taken from semi-hardwood stems of the plant. The cuttings should be approximately 10-15cm long and stripped of their lower leaves. The cuttings should be dipped in a rooting hormone and planted in a well-draining potting mix. The potting mix should be kept moist, and the cuttings should be kept in a warm, bright location, with temperatures above 20°C. Rooting should occur in 2-3 months.
Propagation by Division
Pacouria petersiana var. schweinfurthiana can also be propagated by division. Mature plants can be carefully dug up and divided into smaller sections, each with its own set of roots and shoots. The new plant sections should then be planted in a well-draining potting mix and kept moist. Care should be taken not to damage the roots during the division process.
Disease and Pest Management for Pacouria petersiana (Klotzsch) S.Moore var. schweinfurthiana (Hallier f.) S.Moore
