Hoya Erythrina

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

In its natural habitat in Borneo, it grows as an epiphyte under the canopy of tropical forests, filtering light through the upper foliage. Indoors, this principle is replicated: bright light without direct sunlight intensifies the red coloration of its characteristic veins, while preserving the integrity of its waxy leaves.

In spring and summer, move it slightly away from the windows if there is intense sunlight. In autumn and winter, move it closer to the light source to compensate for the decrease in natural light. A northeast orientation is also suitable if the room is bright enough.

Important tip 🌿Prolonged lack of light dulls the veins of Hoya erythrina and significantly slows its growth. Also avoid cold drafts near windows in winter, which weaken its stems.For interiors with limited sunlight, ourgrow light for dimly lit indoor environmentsfaithfully mimics natural light, without harmful UV rays, to keep the Hoya Erythrina healthy all year round.

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

Like most plants in the Apocynaceae family, Hoya erythrina contains a slightly irritating latex in its stems and leaves. This latex can cause skin irritation upon prolonged contact, and mild digestive upset (nausea, vomiting, excessive salivation) if accidentally ingested.

The toxicity level remains low and serious cases are extremely rare. Nevertheless, caution is still advised, especially with curious young children or pets that might be tempted to chew on the plants.

What precautions should be taken on a daily basis?

Place your Hoya Erythrina in a high position, on a shelf or wall bracket, out of reach of pets and children. This precaution is all the easier to implement since its climbing stems adapt very well to being positioned at a height.

If ingested, consult a doctor or veterinarian as a precaution. With careful placement, the Hoya Erythrina thrives indoors, even with pets.

The leaves of the Hoya Erythrina 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 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 thick and slightly fleshy leaves, the Hoya Erythrina accumulates water reserves, which makes it particularly vulnerable to overwatering: yellowing of the leaves is often the first visible sign of a substrate that has remained too wet for too long.

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 non-aggressive to the waxy foliage of Hoya Erythrina.

The Hoya Erythrina 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.

The Hoya Erythrina develops a compact and fairly fine root system, typical of epiphytes: it slightly appreciates being cramped in its pot, which can delay the need for repotting compared to other tropical plants of similar size.

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 monitor the root condition and recovery after repotting without disturbing the plant.

Prepare a well-draining and aerated substrate, specially designed for Hoya.We recommend ourwell-draining substrates enriched with biostimulantsDesigned to promote drainage, root oxygenation, and healthy long-term growth. In particular, consider ourEnriched drainage mix for climbing succulentsformulated to dry quickly between waterings.

1. Carefully remove the plant from its pot, tapping the pot if necessary 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 with substrate without burying the crown.

Important tip 🌿After repotting, water the plant to help the potting mix settle around the roots and eliminate any air pockets. Ensure that excess water can drain freely.Repotting is always a source of stress for the plant. Repotting every two years is more than enough to ensure balanced growth of the Hoya Erythrina.

The Hoya Erythrina is 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 Hoya Erythrina slows its growth and requires virtually no additional nutrients.

The Hoya Erythrina particularly benefits from a slightly potassium-rich fertilizer in spring, which not only promotes the development of its characteristically veined foliage, but also prepares its stems to produce future fragrant flower umbels.

A well-balanced intake promotes:

• denser foliage with better-colored veins,
• regular stem growth,
• and better overall plant resistance.

👉 For best results, we recommend ourliquid fertilizer formulated for Hoya, with a graduated pipette for precise dosing and quick visible results.

Important tip 🌿Never fertilize Hoya Erythrina 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 keeps your Hoya Erythrina vigorous and healthy 💚

Water the Hoya Erythrina 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.

Thanks to its slightly fleshy and waxy leaves, the Hoya Erythrina is able to store a small reserve of water in its blade, which gives it a natural tolerance to temporary lack of water, while making it very sensitive to prolonged overwatering.

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 fresh or slightly damp, wait a few more days. Use soft water, ideally filtered or left to stand for 24 hours before use, to protect the epiphytic roots of the Hoya Erythrina.

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 Erythrina is propagated by stem cuttings with one or two nodes, ideally in spring or early summer when growth is most active.

Method by stem cutting in sphagnum moss or substrateSelect a healthy Hoya Erythrina stem with at least one well-developed node and one or two leaves. Remove any leaves directly below the node to prevent rot. Make a clean cut just below the node with ourStainless steel blade pruning shears for taking cuttings without damaging the plant: a clean cut promotes root growth and limits the risk of infection.

1. Allow the cutting to air dry for 1 to 2 hours before placing the cutting in place, which reduces the risk of rot.
2. Place the cutting in ourtransparent pots to monitor root developmentfilled with ourpremium substrate adapted to the needs of Hoyaslightly moistened.
3. Place the set in a warm, bright location but out of direct sunlight, at an ideal temperature between 22 and 26 °C.

To promote optimal rooting, you can wrap the base of the node withlive sphagnum moss to maintain root moisturebefore planting the cutting in the substrate. The Hoya Erythrina, whose thick leaves act as a natural reserve, tolerates the rooting phase well without drying out too quickly, making it a relatively pleasant species to propagate from cuttings for Hoya enthusiasts.

Important tip 🌿Hoya erythrina typically takes 4 to 8 weeks to establish roots, depending on the ambient temperature and season. Monitor the substrate moisture carefully, avoiding overwatering during this period. The first signs of successful rooting are the appearance of new leaves or shoots at the node, indicating active root development.
