Cuttings Propagation
The plant can also be propagated with cuttings from semi-hardwood. Cuttings with a length of three to six inches can be taken from the plant in summer, preferably in the morning. The cuttings should be treated with a rooting hormone and planted in pots with a mixture of sand and vermiculite. The pots should be kept in a shaded spot with high humidity until the cuttings take root.
Division Propagation
The plant can also be propagated by division. The plant is dug up and divided into smaller clumps. Each smaller clump should have some roots and a few shoots. These smaller clumps can be planted in individual pots with soil and kept in a shaded spot.
Disease and Pest Management for Anthospermum ciliare L. var. glabrifolium Sond.
Anthospermum ciliare L. var. glabrifolium Sond. is a hardy plant that is resistant to many pests and diseases. However, there are a few common problems that gardeners may encounter when growing this plant.
Common diseases
One of the most common diseases that can affect Anthospermum ciliare var. glabrifolium Sond. is powdery mildew. Powdery mildew is a fungal disease that first appears as white spots on the leaves. Over time, these spots can grow and merge, causing the affected leaves to become distorted and discolored. To manage powdery mildew, it's important to keep the plant well-ventilated and avoid getting the leaves wet when watering. A fungicidal spray can also be applied to manage the disease.
Another common disease that can affect Anthospermum ciliare var. glabrifolium Sond. is leaf spot. Leaf spot is a bacterial disease that causes small, black spots to appear on the leaves. Over time, these spots can grow and merge, causing the leaves to yellow and fall off the plant. To manage leaf spot, it's important to remove infected foliage and avoid getting the leaves wet when watering. A copper-based fungicidal spray can also be applied to manage the disease.
Common pests

Whiteflies are small, winged insects that suck the sap from the leaves of the plant, causing them to yellow and die. To manage whiteflies, it's important to keep the plant well-ventilated and avoid over-fertilizing with nitrogen-rich fertilizers. Sticky traps and insecticidal soap can also be used to manage whiteflies.
Another common pest that can affect Anthospermum ciliare var. glabrifolium Sond. is spider mites. Spider mites are tiny arachnids that suck the sap from the leaves of the plant, causing them to become dehydrated and discolored. To manage spider mites, it's important to keep the plant well-watered and avoid over-fertilizing with nitrogen-rich fertilizers. Insecticidal soap and neem oil can also be used to manage spider mites.
