Propagation is done mainly through seeds or stem cuttings. The best time to sow seeds is in the spring after the last frost. Germination can take up to three weeks, and the seedlings can be transplanted to their permanent location after six to eight weeks. Alternatively, you can take stem cuttings in the late summer or early fall, root them in a rooting hormone, and transplant them in spring.
Watering Needs
Helichrysum nudifolium (L.) Less. var. oxyphyllum (DC.) Beentje is drought-tolerant and doesn’t require much water. However, it would be best if you watered the plant during its early stages of growth. Once the plant is established, it can survive on occasional rainfall. Overwatering can be harmful to the plant as it prefers well-drained soil.
Fertilization
Helichrysum nudifolium (L.) Less. var. oxyphyllum (DC.) Beentje doesn’t require much fertilizer. You can fertilize the plant once a year during the early spring, just before the growing season begins. Use a slow-release organic fertilizer or a balanced granular fertilizer. Avoid over-fertilizing the plant as it can cause excessive foliage growth at the expense of flowers.
Pruning
Pruning your Helichrysum nudifolium (L.) Less. var. oxyphyllum (DC.) Beentje is necessary to encourage bushier growth and more flowers. You can prune the plant in mid-summer by cutting back about a third of its height. This will stimulate the plant to grow more lateral branches, leading to a fuller and more rounded shape. Deadheading the spent flowers will encourage the plant to produce more blooms.
Propagation of Helichrysum nudifolium var. oxyphyllum
Helichrysum nudifolium var. oxyphyllum can be propagated through various methods such as:
Seed Propagation
Seeds from mature plants can be collected and sown in trays filled with seed raising mix or directly into the garden bed. The ideal time for sowing seeds is in spring or autumn. Seeds should be covered with a thin layer of soil and watered consistently. Germination usually occurs within 2-3 weeks.
Cuttings Propagation
Softwood cuttings can be taken during spring from non-flowering stems. The cuttings should be about 8-10 cm in length and stripped of any leaves on the lower half. Dip the cuttings into a rooting hormone and insert them into a pot filled with a well-draining propagation mix. Water the cuttings and keep them in a humid spot with indirect light. Rooting should occur within 3-4 weeks.
Division Propagation
The plant can also be propagated through division during spring. Using a sharp knife or shovel, the plant should be divided into sections, each with its own roots and stem. Each section should be transplanted into a new pot with fresh soil mix. Water the new divisions and grow them until they are established before transplanting into the garden bed.
