Hoya Pubicalyx Silver Spot

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

In its natural Philippine habitat, this epiphytic vine grows under the canopy of tropical rainforests, benefiting from abundant filtered light without ever receiving direct sunlight. Indoors, replicating these conditions is essential to ensure that the silvery speckles on its foliage remain vibrant and contrasting.

In summer, move it slightly away from the window to avoid direct afternoon sunlight. In winter, move it as close as possible to the light source to compensate for the reduced sunlight and maintain proper growth.

Important tip 🌿Prolonged lack of light leads to leggy stems, dull foliage, and a lack of flowering. For rooms with insufficient lighting, ourhorticultural lamp suitable for indoor plantsoffers a full spectrum that faithfully mimics daylight, without harmful UV rays.

Hoya Pubicalyx Silver Spot is considered moderately toxic to cats, dogs, and young children.

Like most members of the Apocynaceae family, it contains a natural latex in its stems and leaves. Prolonged skin contact or ingestion of this latex can cause mild irritation of the mucous membranes, nausea, or temporary digestive upset.

The symptoms observed are generally mild and limited to slight oral or gastric irritation. They do not pose a serious danger to a healthy adult, but may be more bothersome to young children or small animals.

What precautions should be taken on a daily basis?

Place your Hoya Pubicalyx Silver Spot out of reach of pets and small children, high up on a shelf or hanging in a cachepot.

These simple precautions will allow you to fully enjoy the beauty of this tropical vine with complete peace of mind on a daily basis.

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

• If the leaves turn yellow and become limp, 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.

The Hoya Pubicalyx Silver Spot has slightly succulent leaves that naturally store water: localized yellowing on the oldest leaves is often a sign of overwatering rather than disease, and deserves to be monitored as a priority.

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 respectful of your home.

The Hoya Pubicalyx Silver Spot 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 down.
• 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 pubicalyx Silver Spot actually appreciates being slightly root-bound: its compact roots often encourage flowering. Don't choose a container that's too big.

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 system without disturbing the plant.

Prepare a well-draining and aerated substrate, specially designed for Hoyas. We recommend ourwell-draining substrates enriched with biostimulantsDesigned to promote drainage, root oxygenation, and healthy long-term growth. For this repotting, choose ourEnriched drainage mix for climbing succulentsformulated to dry quickly and effectively nourish Hoya roots.

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. However, ensure that excess water can drain freely through the drainage holes.Keep in mind that repotting is always a source of stress for the plant. Repotting every two years is sufficient to ensure healthy and balanced growth.

Hoya Pubicalyx Silver Spot 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 Pubicalyx Silver Spot is particularly sensitive to excess nitrogen, which promotes abundant foliage at the expense of fragrant flowering: opt for a balanced fertilizer specially formulated for Hoya, rich in potassium to stimulate the flower umbels.

A well-balanced intake promotes:

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

👉 For best results, we recommend ourHoya special concentrated liquid fertilizerDesigned to support foliage growth and flowering. Practical advice is printed directly on the back of the label and on the product information sheet, for simple and hassle-free use.

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

Water Hoya Pubicalyx Silver Spot 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.

Thanks to its slightly succulent leaves, the Hoya Pubicalyx Silver Spot naturally stores a reserve of water in its foliage, allowing it to tolerate periods of drought without damage: it is always better to wait a little too long than to water too soon.

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.

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

Nodal stem cutting methodSelect a healthy, vigorous stem at least 10 to 15 cm long, with two to three nodes and a few leaves. Remove the lower leaves to leave the lowest node(s) bare, as this is where the roots will form. UseOur stainless steel blade pruner for a clean cut, made just below a node: a clean cut limits the risk of infection and promotes rapid rooting.

1. Allow the cut to air dry for 30 to 60 minutes to slightly close the wound, which is recommended for latex plants.
2. Place the cutting inOur transparent pots allow you to monitor root development.filled with clean water at room temperature or in thelive sphagnum moss to maintain root moisture, which offers a slightly humid and well-ventilated environment particularly suited to Hoya.
3. Place the cutting in a warm and bright place, out of direct sunlight, at a temperature of at least 20°C.

Once the roots are well developed, transplant the cutting into ourpremium substrate adapted to the needs of Hoya, very draining and formulated to dry quickly between waterings.

Important tip 🌿Rooting of Hoya pubicalyx 'Silver Spot' generally takes 3 to 6 weeks, depending on temperature and light. The first sign of success is the appearance of new leaves at the top of the cutting, indicating that the roots are sufficiently established to support growth. Avoid disturbing the cutting during this period; patience is key to successful propagation of this tropical vine.
