Hoya Serpens

The Hoya Serpens thrives in bright, indirect light, ideally placed 50 cm to 1 meter from an east or west facing window.

Native to the high-altitude Himalayan forests, it is naturally accustomed to receiving light filtered through the canopy. Direct and prolonged sunlight, especially in summer, risks burning its small, particularly sensitive, crinkled leaves. Conversely, a lack of light significantly hinders its slow growth and can compromise flowering.

In summer, move the pot slightly away from the window if the light is very intense. In winter, place it as close as possible to a source of natural light to compensate for the short days.

Important tip 🌿Avoid cold drafts and uninsulated windows in winter, as the Hoya Serpens is sensitive to sudden temperature changes. For dimly lit interiors, ourgrow light for dimly lit indoor environmentsfaithfully mimics natural light, without harmful UV rays, to maintain active growth all year round.

Hoya Serpens is considered moderately toxic to cats, dogs, and young children.

Like most plants in the Apocynaceae family, Hoya Serpens contains a natural latex in its stems and leaves. This latex can cause mild skin or digestive irritation upon prolonged contact or ingestion. Symptoms are generally mild: nausea, slight oral or digestive irritation, and are not serious in most cases.

However, if ingested by an animal or young child, it is advisable to consult a veterinarian or doctor quickly as a precaution.

What precautions should be taken on a daily basis?

Place your Hoya Serpens in a high place, out of reach of animals and young children, on a shelf or hanging in a pot. This simple precaution is enough to prevent any risk of accidental contact.

With a suitable location, the Hoya Serpens coexists perfectly in a home with pets and children, while remaining a decorative and safe plant for everyday use.

The leaves of the Hoya Serpens most often turn yellow due to overwatering, lack of light, or 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 fertilizer.
• If the yellowing is accompanied by small light spots, a dull appearance or fine webbing, it may be a mite infestation, common indoors, especially in dry atmospheres.

Thanks to its slightly succulent leaves, the Hoya Serpens naturally stores water in its foliage. Therefore, rapid and widespread yellowing is often the first sign of overwatering rather than underwatering, which distinguishes it from many other tropical climbing plants.

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, there is cause for concern if several leaves turn yellow rapidly, if the phenomenon spreads to young leaves, or if growth slows down significantly.

In case of a mite infestation, prioritize ourplant-friendly biological treatments, effective and without damaging the delicate foliage of the Hoya Serpens.

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

Repotting is necessary when:

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

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

Note that the Hoya Serpens appreciates being slightly cramped in its pot: its fine and small roots do not need much space, and a pot that is too large would promote water stagnation, risking root rot.

Choose a pot that is 2 cm wider than the old one, and which must have drainage holes. Ourtransparent pots to monitor the rootsare ideal: their transparency allows you to monitor root recovery after repotting without disturbing the plant.

Prepare a very well-draining substrate, designed to dry out quickly between waterings. We recommend ourwell-draining substrates enriched with biostimulants, designed to promote root oxygenation and healthy long-term growth. For Hoya Serpens, ourpremium substrate adapted to the needs of Hoyais particularly recommended.

1. Gently remove the plant from its pot by tapping the pot to loosen the root ball without pulling on the stems.
2. Gently loosen 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 in without burying the crown.

Important tip 🌿After repotting, water moderately to help the potting mix settle around the roots. Ensure that excess water can drain freely. Keep in mind that repotting is always a source of stress: repotting every two years is more than enough for Hoya Serpens.

The Hoya Serpens 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 fertilizing. This is a period of dormancy during which the plant produces few or no new leaves.

Hoya Serpens, as an epiphytic climbing plant with small succulent leaves, particularly benefits from a potassium-enriched fertilizer during periods of active growth, which supports both foliage vitality and flower bud formation.

A well-balanced intake promotes:

• denser, more colorful foliage
• steady growth,
• and improved plant resistance.

👉 For best results, we recommend ourliquid fertilizer formulated for Hoya, adapted to the specific needs of this family and easy to dose thanks to the included graduated pipette.

Important tip 🌿Never fertilize Hoya Serpens in a dry substrate: this could burn the plant's 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 Serpens vigorous and healthy 💚

Water the Hoya Serpens when the substrate has dried out completely, approximately every 10 to 14 days in summer and every 20 to 30 days in winter. Use room temperature water, preferably slightly hard.

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 Serpens has slightly fleshy leaves that allow it to store a small reserve of water. Unlike many tropical plants, it tolerates a slightly too dry substrate better than a waterlogged one, which very quickly leads to rot in its fine and sparsely branched root system.

Important advice:When in doubt, it's always better to wait a little longer than to overwater. Plants adapt better to underwatering than to overwatering, which quickly causes root rot.

Hoya Serpens is propagated by stem cuttings in sphagnum moss or in a very well-draining, slightly moist substrate, ideally in spring or early summer when the plant is in full growth phase.

Preparing the cuttingSelect a healthy stem with at least 2 to 3 pairs of small, round leaves and one or more well-formed nodes. Use ourStainless steel blade pruning shears for taking cuttings without damaging the plantA clean cut just below a node reduces the risk of infection and promotes root development. Remove any leaves on the lower part of the stem that would be buried.

The Hoya Serpens, with its thin stems and small, closely spaced internodes, takes root particularly well in living sphagnum moss kept slightly moist, which reproduces the humidity conditions of the high-altitude Himalayan forests from which it originates.

1. Prepare the cutting with 2 to 3 nodes, making a clean cut below the lowest node.
2. Place the cutting in ourtransparent pots to monitor root developmentfilled withlive sphagnum moss to maintain root moisturearound the stems that are currently rooting.
3. Place the pot in a warm, bright location, out of direct sunlight, at a constant temperature of at least 20°C.

Once the roots are well developed (3 to 5 cm), transplant the cutting into ourEnriched drainage mix for climbing succulents, which dries quickly between waterings and provides an ideal environment for young Hoya roots.

Important tip 🌿Hoya Serpens roots relatively slowly due to its naturally measured growth: expect to wait 4 to 8 weeks before the first well-formed roots appear. Maintain consistent warmth and avoid disturbing the cutting. The most reliable sign of success is the appearance of a new, small, round leaf at the top of the stem cutting.
