Hoya Black Cat (Meredithii IML 3576)

The Hoya Black Cat (Meredithii IML 3576) thrives in bright, indirect light, ideally placed 50 to 100 cm from an east or west facing window.

In its natural habitat, this Hoya grows as an epiphyte under the canopy of Borneo's rainforests, where the light filtered through its foliage is intense but never direct. Indoors, recreating these conditions ensures dark, well-developed foliage. In winter, move the plant closer to a window to compensate for the reduced light.

A south-facing window can be suitable provided that a thin curtain is placed between the glass and the plant, especially between May and September when the sun is strongest.

Important tip 🌿Prolonged lack of light slows growth and can prevent this Hoya from flowering. If your home is naturally dim, ourfull spectrum horticultural lampfaithfully mimics natural light and effectively supports growth, without harmful UV rays for the foliage.

The Hoya Black Cat (Meredithii IML 3576) is considered to be of low toxicity to cats, dogs and young children, but its milky sap may cause mild irritation.

Like most Hoya species, this one produces a white latex when a stem or leaf is injured. This latex can irritate mucous membranes and sensitive skin, both in animals and in young children who might chew the leaves.

If leaves are ingested or the sap comes into contact with them, mild symptoms such as slight oral irritation, nausea, or excessive salivation may occur in animals. These symptoms are generally not serious, but veterinary consultation is recommended if they persist.

What precautions should be taken on a daily basis?

As a precaution, it is advisable to place the Hoya Black Cat (Meredithii IML 3576) out of reach of climbing cats and young children, especially when pruning or handling the plant.

With proper placement, this Hoya can coexist easily with your pets in a caring home.

The leaves of the Hoya Black Cat (Meredithii IML 3576) turn yellow most often due to overwatering, lack of light or 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 Black Cat (Meredithii IML 3576) has particularly fleshy leaves that naturally store water: a substrate that remains wet for too long is the main cause of yellowing in this species, much more so than in Hoyas with finer foliage.

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 safe for your home.

The Hoya Black Cat (Meredithii IML 3576) 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.

This species appreciates being slightly cramped in its pot: a container that is too large retains excess moisture and slows down the drying of the substrate, which is particularly risky for this Hoya with roots sensitive to water stagnation.

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 check root recovery and the condition of the roots after repotting, without having to disturb the plant.

Prepare a very well-draining substrate designed for Hoyas. We recommend ourwell-draining substrates enriched with biostimulantsdesigned to promote drainage, root oxygenation, and healthy long-term growth. In particular, ourpremium substrate adapted to the needs of Hoyaensures rapid drying between waterings, essential for this species.

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 in without burying the crown.

Important tip 🌿After repotting, water moderately to help the potting mix settle around the roots. Ensure that excess water drains freely. Repotting every two years is sufficient to ensure healthy and balanced growth.

The Hoya Black Cat (Meredithii IML 3576) 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.

The Hoya Black Cat (Meredithii IML 3576) is a moderately growing Hoya whose flowering can be stimulated by a regular supply of fertilizer rich in phosphorus and potassium at the end of the growth period: a dosage adapted to this species promotes the formation of flower peduncles without weakening the fleshy foliage.

A well-balanced intake promotes:

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

👉 For best results, we recommend ourliquid fertilizer formulated for HoyaEasy to dose, with fast visible results. Practical tips are 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 Black Cat (Meredithii IML 3576) vigorous and healthy 💚

Water the Hoya Black Cat (Meredithii IML 3576) when the substrate has dried out completely, approximately every 10 to 14 days in summer and every 20 to 25 days in winter. Use room temperature water.

Thanks to its thick and fleshy leaves, the Hoya Black Cat (Meredithii IML 3576) naturally stores water reserves that allow it to tolerate prolonged periods of drought: this storage capacity specific to succulent Hoyas makes it a species particularly sensitive to excess water, much more so than to a lack of it.

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 Black Cat (Meredithii IML 3576) is propagated by stem cuttings with at least one node, ideally in spring or early summer when the plant is in full growth phase.

Preparing the cuttingSelect a healthy, vigorous stem 8 to 12 cm long, with at least two nodes and one or two leaves. Make a clean cut just below a node usingOur pruning shears have a straight point for a clean cut.A sharp stainless steel blade reduces the risk of infection and promotes rapid rooting. Allow the base of the stem to air dry for 1 to 2 hours to close the wound before planting.

Cutting propagation steps:

1. Prepare the cutting and let it heal for a few hours in the open air.
2. Place the cutting inour transparent pots for cuttingsfilled with a slightly moist substrate: their transparency allows you to easily monitor root development without disturbing the plant.
3. Place in a bright, warm location (22 to 26 °C), out of direct sunlight, and maintain a slight moisture in the substrate without excess.

You can also root the cutting inlive sphagnum moss to maintain root moisturewhich offers excellent oxygenation while preventing waterlogging. Once the roots are well-formed, transplant into ourEnriched drainage mix for climbing succulents, ideal to support the development of this young Hoya.

Important tip 🌿Hoya Black Cat (Meredithii IML 3576) typically roots in 3 to 5 weeks, depending on temperature and light. The first roots visible through the transparent pot and the appearance of a new leaf are key signs of successful propagation. Avoid overwatering during this phase: overly moist substrate is the main cause of rooting failure for this fleshy-leaved species.
