Cultivation methods for Manulea viscosa (Aiton) Willd.
Manulea viscosa is a drought-resistant plant that prefers well-drained soils, sandy loam soil being the most suitable. It grows best in full sun and does not tolerate shade well. The plant can be propagated by seeds or cuttings, and it is a relatively easy plant to cultivate.
If cultivating from seeds, plant them in spring in a seed tray at a depth of ¼ inch. Once the plant has two sets of true leaves, transplant it into a larger pot or directly into the ground. Seedlings should be spaced about 12 inches apart, as the plant can grow to about 18 inches in height and width.
If cultivating from cuttings, take a 3-4 inch cutting from a healthy plant and remove the lower leaves. Dip the cut end in rooting hormone, plant in soil, and water thoroughly. Cuttings should be kept in a warm, humid environment.
Watering needs for Manulea viscosa (Aiton) Willd.
Manulea viscosa is a drought-resistant plant, and overwatering can lead to root rot. The plant should be watered when the top inch of soil is dry, and the water should thoroughly penetrate the soil. Watering should be reduced during the winter months, as the plant becomes dormant and requires less water.
Fertilization of Manulea viscosa (Aiton) Willd.
Manulea viscosa does not require a lot of fertilizer, but a small amount of balanced fertilizer can be applied during the growing season. Fertilize every two to three weeks with a general-purpose fertilizer diluted to half strength. Alternatively, you can use slow-release fertilizer that can last up to three months.
Pruning Manulea viscosa (Aiton) Willd.
Pruning Manulea viscosa is not essential, but trimming back dead or damaged branches can promote new growth. The plant can be cut back to about 6 inches in the fall to promote bushier growth in the spring. Pinching back the tips of young plants can encourage bushier growth and more blooms.
Propagation of Manulea Viscosa
Manulea viscosa (Aiton) Willd. is commonly known as the sticky manulea, and it belongs to the Asteraceae family. This perennial shrub is native to South Africa and is mainly propagated through cuttings and seeds.
Cuttings Propagation
The best time to take cuttings for propagation is in spring or summer. Take 5-7cm cuttings from the tips of the plant and remove the lower leaves. Dip the stem ends in rooting hormone and plant them in a pot filled with a well-draining potting mix. Place the pot in a warm and bright location, ensuring that the soil is moist but not waterlogged. After 4-8 weeks, the cuttings should have rooted and can be transplanted into individual pots. They can be planted outdoors when they have established a good root system.
Seed Propagation
Manulea viscosa can be grown from seeds, which are usually readily available. The seeds should be sown in a well-draining potting mix in spring. Sow the seeds thinly and cover them lightly with soil. Water the soil and keep it moist until germination occurs, which is usually around 2-3 weeks. Once the seedlings have grown two sets of true leaves, they can be transplanted into individual pots or planted outdoors.
Overall, Manulea viscosa is an easy plant to propagate, and cuttings are the preferred method. The plant does well in full sun and requires minimal care once established.
