Propagation of Manulea Dubia
Manulea dubia (Skan) Overkott ex Roessler, also known as the False Strawberry, is a perennial plant that grows up to 30 cm tall. The plant is native to the cooler regions of South America and is commonly found in the wild. The plant is primarily propagated through seeds and occasionally by division.
Propagation by Seeds
Propagation by seeds is the most common method used to propagate Manulea dubia. The plant's small seeds are easily germinated with good quality seed starting mix. The seeds should be sown on the surface of the soil, without covering them, and kept moist until they germinate. It takes around 14 to 21 days for the seeds to germinate, and the plant produces small rosettes of leaves.
After the plant begins growing, it should be transplanted into individual pots or onto the ground. The plant prefers well-draining soil and moderate moisture. The plant grows in full sun to partial shade and can thrive in a range of temperatures.
Propagation by Division
Propagation by division is a less common method used to propagate Manulea dubia, mostly due to the plant's small size. The plant can be divided into small clumps, and each clump can be potted or planted in the ground. It is best to perform the division in the early spring before new growth begins.
Dividing the plant is relatively easy and requires digging up the plant. The clump should be separated into smaller sections with roots attached and replanted. However, it should be noted that this process can be quite disruptive to the plant, and it may take several weeks to recover.
In conclusion, Manulea dubia is primarily propagated by seeds, and occasionally by division. Care should be taken when handling the plant, as it is fragile and can be damaged easily.
