Light Requirements

Helichrysum asperum var. glabrum requires full sun exposure for optimal growth. It can tolerate partial shade but its flowering may be reduced. It is best to plant it in areas exposed to sunlight for at least six hours a day.

Temperature Requirements

This plant is native to the dry and arid regions of South Africa and is able to tolerate a wide range of temperatures. It can withstand temperatures as low as 20°F (-6°C) and as high as 100°F (38°C) provided that it is planted in a well-drained soil.

Soil Requirements

Helichrysum asperum var. glabrum thrives in well-drained soils that are sandy or gravelly. It can tolerate poor soil conditions and is drought-resistant but it is susceptible to root rot if the soil is too moist. The pH level of the soil can range from neutral to slightly acidic and does not require heavy fertilization.

Cultivation Methods

Helichrysum asperum (Thunb.) Hilliard & B.L.Burtt var. glabrum Hilliard, also known as the smooth everlasting, is a hardy plant species that grows well in sunny locations with well-draining soil. Growers are encouraged to plant the smooth everlasting in gardens, window boxes, and small containers for easy management.

It is best to cultivate the plant in areas with optimal temperatures of 20 to 25°C. The soil pH should be slightly acidic, ranging from 6.0 to 7.0.

Watering Needs

As a hardy plant, the smooth everlasting does not require excessive watering. Gardeners should water the plant when the soil is dry to the touch. Over watering may cause root rot, so ensure that you do not place the plant in standing water.

During dry spells, provide the plant with deep watering, which ensures that the roots can absorb water from deeper soil layers.

Fertilization

Smooth everlasting plants do not require frequent fertilization, and gardeners should only use a balanced fertilizer once or twice a year during active growth periods. Avoid over-fertilizing as this may cause many problems such as the formation of heavy foliage but poor flowering.

The ideal fertilizers consist of a balanced blend that includes equal parts of nitrogen, phosphorus, and potassium. If you are environmentally conscious, consider using natural options like compost or grass clippings as fertilizers.

Pruning

Pruning is an essential part of managing Helichrysum asperum (Thunb.) Hilliard & B.L.Burtt var. glabrum Hilliard plants. Growers should prune the plant after flowering, which stimulates growth and enhances the appearance of the plant.

During pruning, focus on removing dead, diseased, and damaged stems. Additionally, cutting back the leggy stems encourages better bushier growth and good flower production.

Propagation Methods for Helichrysum Asperum (Thunb.) Hilliard & B.L.Burtt var. Glabrum Hilliard

Helichrysum asperum (Thunb.) Hilliard & B.L.Burtt var. glabrum Hilliard, commonly known as the Cape Gold plant, is a South African native shrub that belongs to the Asteraceae family. Propagation is the process of multiplying a plant to obtain more individuals with the same genetic makeup. Helichrysum asperum can be propagated by seeds, cuttings, and layering.

Propagation by seeds

Propagation by seeds is one of the simplest and most common methods of propagating Helichrysum asperum plants. The Cape Gold plant produces small, black, and light seeds that are easy to harvest and plant. To propagate by seeds:

• Collect seeds from a healthy and mature plant. The seeds should be dry and dark.
• Clean the seeds properly to remove dirt, debris, and other particles.
• Sow the seeds in a planting medium with good drainage. The seeds should be buried shallowly and the soil should be kept moist.
• Place the planting container in a well-lit area, but avoid direct sunlight.
• Germination should occur in about two weeks.

Propagation by cuttings

Propagation by cuttings is another common method of propagating Helichrysum asperum plants. Cuttings should be taken from a healthy and mature plant to obtain a genetic copy of the original plant. To propagate by cuttings:

• Select a healthy stem from the plant and cut a 10-15 cm section below the node.
• Remove the leaves from the bottom half of the cutting.
• Dip the cut end of the cutting in a rooting hormone powder.
• Plant the cutting in a soilless media, such as perlite or vermiculite.
• Keep the soilless media moist and place the cutting in a well-lit area with indirect sunlight.
• Roots should start to develop in about two weeks.

Propagation by layering

Propagation by layering is a less common but effective method of propagating Helichrysum asperum plants. This method involves burying a low-growing stem of a mature plant into the ground to allow it to develop roots. To propagate by layering:

• Select a low-growing stem of the plant and bend it towards the ground.
• Make a small wound on the stem of the plant and dust it with a rooting hormone.
• Bury the wounded section of the stem into the soil and cover it with soil.
• Keep the soil moist and wait for roots to develop.
• After the roots have developed, cut the stem from the parent plant and transplant it to a new location.

Disease Management

Helichrysum asperum var. glabrum is relatively resistant to many common plant diseases and can tolerate several environmental stressors. However, there are certain fungal and bacterial infections that can harm the plant, such as:

• Botrytis blight
• Leaf spot
• Rust
• Powdery mildew

To manage these diseases, it is important to maintain good sanitation practices. Remove any infected plant parts and dispose of them properly. Avoid overhead watering, and ensure good air circulation around the plant. Fungicides may also be required, but it is important to follow the manufacturer's directions closely.

Pest Management

Helichrysum asperum var. glabrum is relatively pest-resistant, but several insects and mites may still cause damage to the plant. Some common pests include:

• Aphids
• Spider mites
• Thrips
• Whiteflies

To manage these pests, start with a gentle blast of water to dislodge them from the plant. Beneficial insects, such as ladybugs or lacewings, can also be introduced to help control populations. Insecticidal soaps or oils may be necessary, but again, it is important to follow the manufacturer's instructions carefully.
