Propagation by seeds
The propagation of Argyroderma strictum L.Bolus by seeds is the most common method. The seeds should be sown in the late winter or early spring when temperatures are warm enough for the plant to germinate. The seeds should be placed on top of a well-draining mix that contains sand, perlite, and peat moss. They should be watered well and covered lightly with a clear plastic sheet to keep the humidity high. The seeds should germinate within one to three weeks.
Vegetative propagation
Vegetative propagation is another method used to propagate Argyroderma strictum L.Bolus. This method involves taking cuttings from the parent plant and rooting them. The best time to take cuttings is during the growing season in the summer. The cuttings should be taken from basal shoots that are at least two years old. The cuttings should be allowed to dry for a few days before planting them in a well-draining mix. The cuttings should be watered sparingly until they develop roots.
Division
Argyroderma strictum L.Bolus can also be propagated by division. This method is ideal for mature plants that have formed large clumps. The clumps can be carefully separated into smaller sections, making sure that each section has a portion of the root system. The divided sections should be planted in a well-draining mix and watered sparingly until they establish themselves.
Propagation of Argyroderma strictum L.Bolus may take some time, but it is a rewarding process that allows plant lovers to expand their collection and share this unique plant with others.
Disease Management for Argyroderma strictum L.Bolus
Argyroderma strictum L.Bolus is a hardy plant and generally not susceptible to many diseases if provided with the right growing conditions. However, some common diseases that may affect these plants include:

To manage root rot, avoid overwatering the plant and ensure the soil has adequate drainage. Additionally, applying a fungicide to the soil may help combat the fungal infection.
- Leaf spot: This disease shows as small, yellowish-brown spots on the leaves, which may eventually turn grey and fall off. To manage leaf spot, remove infected leaves and avoid overhead watering that can spread the disease. Apply a fungicide periodically to prevent its occurrence.
- Viral infections: Several viral infections may affect Argyroderma strictum L.Bolus, with symptoms including yellowing and distortion of leaves, stunted growth, or death of the plant. There is no cure for viral infections, and plants affected must be removed to prevent further spread.
Pest Management for Argyroderma strictum L.Bolus
Like most plants, Argyroderma strictum L.Bolus may occasionally be affected by pests. Some of the common pests that may affect these plants include:
- Spider mites: These pests are tiny and can be difficult to detect, but they are harmful to the plant. They suck sap from the leaves and cause yellowish webbing to appear on the plant. To control spider mites, regularly inspect the plant and isolate the affected plant to prevent further infestation. Apply insecticidal soap or neem oil to eradicate spider mites.
- Mealybugs: Mealybugs are also sucking insects and, if left unchecked, can cause stunted growth and death of the plant. They are usually found on stems and undersides of leaves and appear like cottony masses. To manage mealybugs, make use of a cotton swab dipped in rubbing alcohol or neem oil, and apply to eradicate these pests.
- Scale insects: Scale insects resemble tiny bumps that appear on the plant's stems and leaves. They can cause chlorosis, stunted growth, and death of the plant.
