Hoya Lacunosa Mint

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

In its natural habitat in Southeast Asia, it grows as an epiphyte under the canopy of tropical rainforests, where light is filtered by the foliage. Indoors, replicating these conditions promotes dense, pearly foliage and regular flowering. It is essential to avoid direct sunlight, which causes irreversible scorch marks on its small, fleshy leaves.

In winter, move the plant closer to the window to compensate for the reduced light. In spring and summer, a light curtain is enough to filter the most intense rays on a south-facing window.

Important tip 🌿Prolonged lack of light results in a lack of flowering and progressive etiolation of the stems. For dimly lit rooms, ourhorticultural lamp suitable for indoor plantsfaithfully imitates natural light and allows your Hoya Lacunosa Mint to remain vigorous all year round.

Hoya Lacunosa Mint is considered non-toxic to cats, dogs, and young children according to available data from the ASPCA.

Unlike other popular houseplants, Hoya lacunosa 'Mint' does not contain significant amounts of calcium oxalate or alkaloid compounds known to be harmful. It produces a slight latex when the stems are cut, which may cause mild skin irritation in people with sensitive skin, but this is not serious.

If large quantities of leaves are ingested, mild nausea or digestive upset may occur in animals due to the fleshy nature of the foliage. This is a temporary discomfort and not a serious case of poisoning.

What precautions should be taken on a daily basis?

As a precaution, it is advisable to place the Hoya Lacunosa Mint out of reach of cats, who might be interested in its small leaves or trailing stems. Young children, who are drawn to plants, will be safer if the plant is placed up high.

Overall, Hoya Lacunosa Mint remains one of the safest climbing plants to welcome into a home with pets or children, subject to a few common-sense precautions.

The leaves of Hoya Lacunosa Mint 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 on the stems, it may be a mite infestation, common in dry atmospheres.

Since Hoya Lacunosa Mint is a light succulent plant, its fleshy leaves serve as a natural water reserve: repeated overwatering is the most frequent cause of yellowing in this species, as its fine roots do not tolerate prolonged asphyxiation well.

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 Lacunosa Mint 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 despite favorable conditions.
• or that the substrate compacts too quickly after watering.

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

Note: Hoya Lacunosa Mint prefers to be slightly root-bound, as a container that is too large retains moisture for too long and promotes root rot. Choose a pot only 2 cm wider than the old one.

Choose a pot with drainage holes. Ourtransparent pots to monitor the rootsare ideal: their transparency allows you to observe root regrowth without disturbing the plant.

Prepare a very well-draining substrate designed for Hoyas. We recommend ourComplete range of substrates for tropical plants, in particular ourEnriched drainage mix for climbing succulentsformulated to dry quickly and nourish the roots deeply.

1. Gently remove the plant from its pot by tapping the pot to loosen the root ball without pulling on the stems.
2. Gently untangle the roots if they are compacted, without breaking them.
3. Place a layer of substrate at the bottom, position the plant upright and fill in without burying the crown.

Important tip 🌿After repotting, water moderately to help the potting mix settle around the roots. Then wait until the potting mix is ​​completely dry before watering again, as freshly repotted roots are more sensitive to excess moisture.

The Hoya Lacunosa Mint 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 plant slows its leaf growth and prepares for its next flowering.

Hoya Lacunosa Mint particularly benefits from an enriched supply of potassium during the flowering period, as this element promotes the formation of the fragrant umbels characteristic of the species.

A well-balanced intake promotes:

• denser, more colorful, pearly foliage
• steady growth of climbing stems,
• and a more abundant, fragrant bloom.

👉 For best results, we recommend ourliquid fertilizer formulated for Hoya, designed to support both leaf growth and flowering, with a graduated pipette for precise dosing.

Important tip 🌿Never fertilize Hoya Lacunosa Mint in a dry substrate: this could burn its fine roots.Water normally first, then apply diluted fertilizer 2 to 3 days later. Regular but moderate fertilization will keep your Hoya Lacunosa Mint vigorous and blooming profusely 💚

Water the Hoya Lacunosa Mint 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.

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.

Like all Hoyas, Hoya lacunosa 'Mint' has semi-succulent leaves that naturally store water, allowing it to tolerate periods of drought without suffering. This characteristic makes it much more sensitive to overwatering than underwatering. Use soft water, as mineral deposits can gradually dull the pearly sheen of its foliage.

Important advice:When in doubt, it's always better to wait a little longer than to overwater. The roots of Hoya Lacunosa Mint rot quickly if subjected to prolonged excess moisture, especially in winter when the plant is dormant.

Hoya Lacunosa Mint is propagated by stem cuttings in water or in a light and well-draining substrate, ideally in spring or early summer when vegetative vigor is at its maximum.

Selection and preparation of the cuttingChoose a healthy stem with at least 2 to 3 well-formed nodes and 2 pairs of leaves. Remove the leaves from the lowest node, which will be submerged or buried in the substrate. UseOur stainless steel blade pruner for a clean cut, just below a node, in order to promote rooting and limit any risk of infection.

Steps to successfully propagate Hoya Lacunosa Mint from cuttings:

1. Take a cutting of 8 to 12 cm with at least 2 nodes, make a clean cut with disinfected secateurs, and let the wound dry for 30 minutes before placing it in its rooting medium.
2. Place the cutting inOur transparent pots allow you to monitor root development.with temperate fresh water or in a slightly moist substrate, ensuring that the lower node is in good contact with the medium.
3. Keep the cutting in a warm and bright place, out of direct sunlight, at a stable temperature between 20 and 25°C.

Once the roots have developed in water (4 to 6 weeks), transplant into ourpremium substrate adapted to the needs of Hoya, very well-draining, to allow the young, fine roots to establish themselves without risk of suffocation. You can also root directly inlive sphagnum moss to maintain root moisture, which maintains a constant humidity level around the nodes during rooting, a method that is particularly effective for this small species with thin stems.

Important tip 🌿Hoya lacunosa 'Mint' produces roots in 3 to 6 weeks, depending on the ambient temperature. Success is confirmed when new, small leaves begin to appear at the top of the cutting, a sign that the root system is active. Avoid pulling on the stem to check for rooting: the transparency of the pots will give you all the necessary information without disturbing the plant.
