Hoya Silver Dollar

The Hoya Silver Dollar thrives in bright, indirect light, ideally placed 50 to 100 cm from an east or west facing window.

In its natural Asian habitat, it grows under the canopy of tropical forests, filtering light through its dense foliage. This filtered exposure is what needs to be replicated indoors: bright light without direct sunlight hitting its silvery leaves, which could discolor or burn them.

In summer, move it slightly away from south-facing windows. In winter, move it closer to the light source to compensate for the decrease in natural light and maintain steady growth.

Important tip 🌿Insufficient light is the primary cause of failure to flower in Hoya Silver Dollar. Insufficient light also slows stem growth and gradually dulls the silvery sheen of the leaves.For dimly lit rooms, ourfull spectrum horticultural lampfaithfully imitates natural light, without harmful UV rays, to maintain beautiful vitality all year round.

The Hoya Silver Dollar is considered moderately toxic to cats, dogs, and young children.

Like most plants in the Apocynaceae family, Hoya Silver Dollar contains a latex in its stems and leaves that can cause irritation of the mucous membranes if ingested or through prolonged skin contact. While not severely toxic, reasonable caution is advised, especially with young children and curious pets.

If ingested by an animal, symptoms such as mild vomiting, excessive salivation, or digestive irritation may appear. These symptoms are usually benign, but it is advisable to contact your veterinarian as a precaution.

What precautions should be taken on a daily basis?

Place your Hoya Silver Dollar in a high location or in a room that is difficult for animals and young children to access, for example on a shelf or suspended in a pot.

With a few precautions for placement, this climbing plant with silvery foliage coexists perfectly in a home with animals and children, without serious risk provided that normal supervision is maintained.

The leaves of the Hoya Silver Dollar most often turn yellow due to overwatering, insufficient light, or a nutrient deficiency.

• If the leaves turn yellow and become soft or translucent, the problem usually stems from excess water causing the beginning of root rot.
• If the leaves gradually turn yellow while remaining firm and dry, the plant often lacks light or nutrients.
• If the yellowing is accompanied by small light spots, a dull appearance or fine webbing on the stems and the underside of the leaves, it may be a mite infestation, common in dry atmospheres.

The Hoya Silver Dollar, with its fleshy and waxy leaves, naturally stores water reserves: a yellowing of the lower leaves accompanied by a soft wilting is therefore often a sign of overwatering, well before symptoms become visible on the surface.

Important tip 🌿One or two old leaves turning yellow from time to time is perfectly normal: it is part of the plant's natural cycle.On the other hand, you must act quickly if several leaves turn yellow at the same time, if the phenomenon affects young shoots, or if the stems soften at their base.

The Hoya Silver Dollar is ideally repotted in the spring, between March and May, when growth actively resumes.

Repotting is necessary when:

• The roots emerge through the drainage holes.
• Growth is slowing despite good exposure.
• or that the substrate compacts too quickly after watering.

As a general rule, repotting every 2 years is sufficient for an adult plant.

The Hoya Silver Dollar appreciates being slightly cramped in its pot: its fine and compact roots develop their network better when they have limited space, which also promotes flowering rather than just vegetative growth.

Choose a pot 2 to 3 cm wider than the old one, and make sure it has drainage holes. Ourtransparent pots to monitor the rootsare ideal: their transparency allows you to easily check the root condition after repotting, without disturbing the plant.

Prepare a very well-draining substrate, specially designed for Hoya.We recommend ourwell-draining substrates enriched with biostimulantsdesigned to promote drainage, root oxygenation, and healthy long-term growth. For Hoya Silver Dollar, choose ourEnriched drainage mix for climbing succulents, designed to dry quickly between waterings.

1. Gently remove the plant from its pot by tapping the pot to loosen the root ball without pulling on the stems.
2. Gently untangle the roots if they are very compacted, without breaking them.
3. Place a layer of substrate at the bottom of the pot, position the plant upright, then fill with substrate without burying the crown.

Important tip 🌿After repotting, water moderately to help the substrate settle around the roots. Ensure that excess water drains freely.Repotting every two years is more than enough: the Hoya Silver Dollar flowers better when its roots are slightly constrained.

The Hoya Silver Dollar should be fertilized every 2 to 3 weeks from March to October, with a liquid fertilizer diluted in the watering water.

During autumn and winter, from November to February, significantly reduce or stop fertilization. This is a period of dormancy during which the plant produces few or no new shoots.

The Hoya Silver Dollar benefits from a slightly potassium-rich fertilizer during the flowering period: this supply promotes the formation of peduncles and the quality of fragrant umbels, in addition to good light.

A well-balanced intake promotes:

• denser foliage with a pronounced silvery sheen,
• regular growth of twining stems,
• and better resistance to seasonal fluctuations.

👉 For best results, we recommend ourliquid fertilizer formulated for Hoya, designed to support growth and flowering with a graduated pipette for precise and safe dosing.

Important tip 🌿Never fertilize Hoya Silver Dollar in a dry substrate: this could burn its fine roots.Water normally first, then apply diluted fertilizer 2 to 3 days later, when the soil is slightly moist. Regular but moderate fertilization will keep your Hoya Silver Dollar vigorous and healthy 💚

Water the Hoya Silver Dollar when the substrate has dried out completely, approximately every 10 to 14 days in summer and every 21 to 30 days in winter. Use room temperature water.

How do I know when to water?

The finger test remains the most reliable method: insert your index finger into the substrate to a depth of 2 to 3 cm. If the substrate is dry, it's time to water. If it's still damp, wait a few more days.

The Hoya Silver Dollar has fleshy, waxy leaves that allow it to naturally store water reserves: this epiphytic adaptation gives it good drought tolerance, but makes it particularly vulnerable to overwatering, which quickly rots its roots. Use soft or filtered water to preserve the silvery sheen of its foliage.

Important advice:When in doubt, it's always better to wait a little longer than to overwater. The roots of the Hoya Silver Dollar tolerate a dry substrate between waterings much better than prolonged overwatering.

Hoya Silver Dollar is propagated by stem cuttings with at least one node, ideally in spring or early summer when growth is active.

Stem cutting methodSelect a healthy, vigorous stem 10 to 15 cm long with at least one node and two well-formed leaves. Make a clean cut just below a node using ourStainless steel blade pruning shears for taking cuttings without damaging the plantA clean cut reduces the risk of infection and promotes rooting. Allow the cut to heal for 30 to 60 minutes in the open air before planting the cutting, which is an important consideration for Hoya species with latex.

1. Prepare the stem by removing the leaves located below the node intended to enter the rooting medium.
2. Place the cutting in ourtransparent pots to monitor root developmentfilled with ourlive sphagnum moss to maintain root moisturewhich maintains constant moisture around the knot without risk of rot.
3. Place the set in a warm and bright location, away from direct sunlight, ideally between 22 and 26°C.

Once the roots have formed and are clearly visible through the transparent pot, transplant the young cutting into ourpremium substrate adapted to the needs of Hoya, very draining and enriched with biostimulants to support the first weeks of autonomous growth.

Important tip 🌿Hoya Silver Dollar typically takes 3 to 6 weeks to root, depending on the ambient temperature and the vigor of the cutting. The first signs of success are the appearance of new leaves or small shoots at the nodes, indicating that the roots are well established. Maintain consistent warmth and avoid drafts throughout this period.
