Hoya Kerrii

The Hoya Kerrii thrives in bright, indirect light, ideally placed 50 to 80 cm from an east or west facing window.

In its natural habitat in Southeast Asia, the Hoya kerrii grows beneath the canopy of rainforests, filtering light through its dense foliage. It is accustomed to bright light but never directly exposed to the scorching midday sun. Indoors, an east-facing window provides it with soft, pleasant morning light, while a west-facing window offers warm light in the late afternoon.

In winter, move your Hoya Kerrii closer to the brightest available window to compensate for the reduced sunlight. In summer, ensure that direct midday sun does not hit its fleshy leaves directly, as this can cause irreversible scorch marks on the central leaves.

Important tip 🌿The single-leaf Hoya Kerrii, often sold as a simple, nodeless leaf cutting, will never produce new stems or additional leaves: this is a botanical characteristic specific to this species. For chronic light deprivation, ourfull spectrum horticultural lampfaithfully mimics natural light and actively supports the growth of your plant.

Hoya Kerrii is considered to have low toxicity for cats, dogs and young children, but it is not entirely harmless if ingested.

Like many plants in the Apocynaceae family, Hoya kerrii contains a whitish latex in its stems and leaves. This latex can cause mild skin irritation in people with sensitive skin when handled, and mild irritation of the mucous membranes if ingested.

If a large quantity is ingested by an animal or child, mild symptoms may appear: nausea, excessive salivation, or mouth irritation. These symptoms are usually mild and temporary, but a medical or veterinary consultation is recommended as a precaution.

What precautions should be taken on a daily basis?

As a precaution, place your Hoya Kerrii in a location out of reach of young children and pets, especially cats who might be tempted to chew its thick, fleshy leaves.

With careful placement, the Hoya Kerrii can easily coexist in a home with pets and children, while preserving everyone's safety on a daily basis.

The leaves of the Hoya Kerrii 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.

The Hoya Kerrii has fleshy leaves that serve as a natural water reserve: when yellowing occurs on these thick, waxy leaves, it often indicates prolonged stress, as this species is much more tolerant of drought than of persistent excess water.

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 gentle on your Hoya Kerrii and your home.

The Hoya Kerrii 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 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 Kerrii prefers to be slightly cramped in its pot: its fine and small roots appreciate a modestly sized container, which also limits the risk of water stagnation in a substrate that is too large.

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 observe 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 this species, choose ourEnriched draining mix for climbing succulents, designed 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. 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.

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

Due to its naturally slow growth, Hoya Kerrii is not a heavy consumer of fertilizer: regular but moderate applications are more than enough to support its development and encourage the formation of its fragrant flower umbels at maturity.

A well-balanced intake promotes:

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

👉 For best results, we recommend ourHoya special concentrated liquid fertilizerFormulated to meet the specific needs of this species and support both leaf growth and flowering. Practical advice is included 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 Kerrii vigorous and healthy 💚

Water the Hoya Kerrii 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.

Thanks to its fleshy, waxy leaves, the Hoya Kerrii naturally stores water: this ability, unique to succulents, allows it to tolerate extended periods without watering much better than the vast majority of tropical houseplants. In winter, it is perfectly normal to water it very sparingly, or even not at all, for several weeks.

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 Kerrii is propagated by stem cuttings with at least one node, ideally in spring or early summer when the plant enters its active growth phase.

Why the stem with a knot is essentialA simple heart-shaped leaf cut without a node will never produce a new plant: it can survive in a pot for years without ever producing a stem or additional leaves. To obtain a Hoya Kerrii that truly thrives, it is essential to take a stem cutting with at least one node, ideally two, with one or two fleshy leaves attached. Use ourStainless steel blade pruning shears for taking cuttings without damaging the plantthe tissues, thus promoting rooting and limiting the risk of infection.

1. Take a stem cutting approximately 8 to 12 cm long, with at least one well-formed node and one or two leaves. Allow the cut end to air dry for 1 to 2 hours before placing it in the rooting medium.
2. Place the cutting in ourOur transparent pots allow you to monitor root development.filled with water or a very slightly damp substrate, ensuring that the node is fully submerged or in contact with the medium.
3. Place the cutting in a warm and bright location, out of direct sunlight, at a stable temperature between 20 and 25 °C.

To promote root development, you can also use ourlive sphagnum moss to maintain root moisturearound the node during the rooting phase. Once the roots are well developed, transplant the young plant into ourpremium substrate adapted to the needs of Hoya, very well draining and designed to dry quickly between waterings.

Important tip 🌿Hoya kerrii typically takes between 4 and 8 weeks to root, depending on ambient temperature and light. The first firm, white roots visible through the clear pot or in the water indicate that the cutting is progressing well. Avoid handling the cutting excessively during this period and maintain a slightly humid environment to encourage root development.
