Light Requirements
Helichrysum arussense Chiov. requires full sunlight for optimal growth. The plant needs at least six hours of direct sunlight every day. If grown indoors, it is recommended to keep the plant near a south-facing window or provide artificial lighting to simulate sunlight.
Temperature Requirements
The plant thrives in warm temperatures. The ideal temperature range for Helichrysum arussense Chiov. is between 20 °C to 30 °C (68 °F to 86 °F). The plant can tolerate temperatures up to 40 °C (104 °F) but may require additional watering during hot summer months.
Soil Requirements
The plant prefers well-drained soil that is rich in organic matter. The soil pH should be between 6.0 to 7.5. For best results, mix compost or organic matter with the soil before planting. Helichrysum arussense Chiov. can tolerate slightly acidic or alkaline soils.
The plant requires moderate watering and can withstand short periods of drought. Overwatering can lead to root rot and other fungal diseases. It is recommended to water the plant once a week or when the top inch of soil has dried out.
Cultivation Methods
Helichrysum arussense Chiov. thrives in well-draining soils with a pH of 6.0 to 7.5 and an altitude of 1,800 to 2,000 meters above sea level. Propagation can be done through seeds or vegetative propagation. Seeds can be sown in seedbeds during the rainy season, while cuttings are best taken from mature plants. The plants should be placed in a sunny location with good air circulation.
Watering Needs
Helichrysum arussense Chiov. requires adequate water during the rainy season but must be watered sparingly during the dry season. Over-watering can lead to root rot, while under-watering can cause stunted growth and reduced flower production. Watering should be done in the early morning or late evening hours to reduce water loss due to evaporation.
Fertilization
Helichrysum arussense Chiov. requires a balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Fertilization should be done once a month during the growing season, starting from the second month after planting. Over-fertilization can lead to excessive foliage growth and reduced flower production.
Pruning
Pruning Helichrysum arussense Chiov. helps to promote bushy growth and increase flower production. The plants should be pruned at the beginning of the rainy season to remove dead branches and promote the growth of new shoots. Pinching off the tips of young plants helps to encourage branching and increase flower yield.
Propagation of Helichrysum arussense Chiov.
Helichrysum arussense Chiov. can be propagated through several methods, including seed propagation, stem cutting propagation, and division propagation.
Seed propagation
Seeds for Helichrysum arussense Chiov. can be collected from the plant after blooming. The seeds should be sown in a well-draining soil mix and kept consistently moist until germination. Germination can take up to a few weeks. Once the seedlings have developed true leaves, they can be transplanted to their permanent location.
Stem cutting propagation
Stem cuttings from Helichrysum arussense Chiov. can be taken from a healthy parent plant during its active growth phase. The cuttings should be approximately 4-6 inches long and stripped of the lower leaves. The cuttings should be dipped in a rooting hormone and planted in a well-draining soil mix. They should be kept moist and in a humid environment until root development occurs. Once roots have developed, the new plant can be transplanted to its permanent location.
Division propagation
Helichrysum arussense Chiov. can be propagated by dividing the parent plant. This method is best done in the early spring before active growth begins. The parent plant should be dug up and carefully divided into sections. Each section should have its own root system and healthy top growth. The divided sections should be transplanted into their own location with well-draining soil and kept consistently moist until established.

To manage spider mites, you can spray the plant with a mixture of one-part alcohol and two parts water. You can also increase the humidity around the plant by misting it regularly.
2. Aphids
Aphids are small insects that can cause distortion and curling of leaves as they feed on the sap of plants. To manage aphids on your Helichrysum arussense Chiov., you can spray the plant with a mixture of one-part dish soap and nine parts water.
