The plant can be grown both indoors and outdoors, and it is an excellent way to add some life and color to your garden. If growing indoors, it is essential to ensure that the plant is in a well-lit area with plenty of natural light.
Watering Needs
It is vital to water Helichrysum aureum consistently to ensure it remains hydrated. The plant generally requires frequent watering, with the soil kept continuously moist but not waterlogged. Too much water can cause root rot, while too little water can cause the plant to wilt and die.
The best way to ensure that the plant is properly hydrated is to water it enough to soak the soil and let it dry slightly before the next watering.
Fertilization
Helichrysum aureum requires regular fertilization to grow vigorously and produce beautiful blooms. It is crucial to use a balanced fertilizer with a 15-15-15 NPK ratio or similar. The fertilizer should be applied during the growing season (spring and summer) at least once a month.
It is worth noting that over-fertilizing the plant can lead to rapid growth and distorted flowers.
Pruning
Pruning is essential to maintain the shape and vitality of Helichrysum aureum. It is best to prune the plant during the growing season, mainly in the summer. During this time, you can prune the plant to promote bushier growth and encourage more blooms.
It is worth noting that the plant can be cut back severely, but it should not be pruned during the winter months when the plant is dormant.
After pruning, it is essential to remove any dead or diseased leaves and branches as they can harbor pests and diseases.
Propagation methods for Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard
Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard, commonly known as the everlasting daisy, is a perennial plant that belongs to the Asteraceae family. Propagation of this plant can be achieved through various methods which include:
Seed propagation
Seeds of the Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard can be collected when the flowers have dried or from a seed supplier. The seeds should be sown during the fall season in well-draining soil, either directly into the ground or in seed trays. When sowing in seed trays, the seeds should be covered lightly with a thin layer of soil and kept moist. The seedlings should emerge after about two weeks and be transplanted to their permanent positions after they have developed their second set of true leaves.
Cuttings
Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard can also be propagated through cuttings taken in the summer season. The cuttings should be about 6-8 cm in length and taken from the plant's new growth. The cuttings should be dipped in a rooting hormone powder and planted in a well-draining soil mixture. The cuttings should be kept moist and in a shaded area until they have developed roots, which should happen after about 4-6 weeks. The newly propagated plants should be kept in a shady area for a few days before transplanting to their permanent positions.
Division
Division is another propagation method suitable for mature Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard plants. This method should be carried out during spring when the plants have not started to actively grow. The plant should be carefully dug up, and the roots separated into smaller sections. Each section should be planted in a well-draining soil mixture and kept moist. The newly propagated plants should be kept in a shady area for a few days before transplanting to their permanent positions.
Disease and Pest Management for Helichrysum aureum (Houtt.) Merr. var. serotinum Hilliard

Botrytis Blight
Botrytis blight is a fungal disease that affects the flowers and leaves of Helichrysum aureum. It causes the petals to turn brown and become mushy. To manage this disease, ensure that the plants are spaced appropriately to maximize air circulation. Additionally, avoid wetting the leaves and flowers during watering, and remove diseased flowers and leaves immediately.
Root Rot
Root rot is a fungal disease that affects the roots of the plant, causing them to turn brown and decay. It is caused by overwatering or poorly drained soil. To manage this disease, ensure that the soil is well-drained, and avoid overwatering. Additionally, remove infected plants to prevent the spread of the disease to other plants.
Pests
Helichrysum aureum var. serotinum Hilliard can also be affected by several pests. Some of the common pests include:
Spider Mites
Spider mites are tiny pests that suck the sap from the plant, causing the leaves to turn yellow and dry. To manage spider mites, use an insecticidal soap or neem oil. Additionally, prune off the infected areas and get rid of the debris around the plant. This helps to reduce the breeding sites of the mites.
Whiteflies
Whiteflies are small, white insects that suck the sap from the plant, causing yellowing and wilting of leaves. To manage whiteflies, use yellow sticky traps to trap the adults and avoid using excessive nitrogen fertilizers, as they attract whiteflies. Additionally, periodically spray the plant with a solution of water and insecticidal soap or neem oil.
Aphids
Aphids are small, soft-bodied insects that suck the sap from the plant, causing yellowing and curling of leaves. To manage aphids, use an insecticidal soap or neem oil. Additionally, prune off the infected areas and remove any weeds around the plant, which may harbor the aphids.
In conclusion, managing diseases and pests is essential for maintaining the health of Helichrysum aureum var. serotinum Hilliard. Regular inspection is necessary, and appropriate management strategies should be implemented to prevent the spread of diseases and pests.
