Hoya lacunosa sp. Laos

The Hoya Lacunosa sp Laos prefers bright, indirect light and should never be exposed to prolonged direct sunlight.

In its natural Laotian habitat, it grows in the partial shade of forest canopies, with light filtered through the foliage of host trees. An east- or west-facing window is ideal. In summer, move it slightly away from a south-facing window to prevent leaf scorch.

In autumn and winter, move it closer to the light source to compensate for reduced sunlight. A location that is too dark will stunt growth and prevent the characteristic fragrant blooms of this Hoya.

Important tip 🌿Avoid cold drafts near windows in winter, as these can cause the thick leaves to yellow.For rooms with low light, our full-spectrum grow light faithfully mimics natural light without harmful UV rays.

Hoya lacunosa sp. Laos is considered non-toxic to cats, dogs, and young children according to available data on the Hoya genus.

Hoyas belong to the Apocynaceae family, some members of which contain alkaloids, but the Hoya genus itself is not listed by the ASPCA as hazardous to common household pets. No highly toxic substances have been identified in this species.

However, ingesting large quantities may cause mild, temporary digestive irritation in highly sensitive animals due to the waxy texture of the leaves.

What precautions should be taken on a daily basis?

As a precaution, keep it out of reach of young children and curious pets, particularly to protect the delicate flower stalks.

This Hoya can be kept safely around children and pets, making it a reassuring choice for most households.

The leaves of the Hoya Lacunosa sp Laos most often turn yellow due to overwatering, insufficient light, or a nutrient deficiency.

• If the leaves turn yellow and become limp, the problem is generally caused by overwatering, which leads to the early stages of root rot.
• If the leaves gradually turn yellow while remaining firm and dry, the plant is often lacking light or fertilizer.
• If the yellowing is accompanied by small light-colored spots, a dull appearance, or fine webbing, it may be a spider mite infestation, which is common indoors, especially in dry conditions.

In the Hoya Lacunosa sp Laos, yellowing sometimes occurs after a sudden change in location, as this Hoya with thick foliage is particularly sensitive to sudden changes in light exposure.

Important tip 🌿One or two old leaves turning yellow from time to time is completely normal.However, you should be concerned if several leaves turn yellow quickly or if the phenomenon spreads to the young leaves.

In the event of a spider mite infestation, choose our biological spider mite control solutions, which are effective and plant-friendly.

The Hoya Lacunosa sp Laos is ideally repotted in spring, between March and May, when growth actively resumes.

Repotting is necessary when:

• roots grow out of the drainage holes,
• growth slows down,
• or the substrate compacts too quickly after watering.

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

After receiving your Hoya Lacunosa sp Laos, wait 2 to 3 weeks for it to acclimate before considering repotting, allowing the plant to adapt smoothly to its new environment. Note that Hoyas often bloom better when they are slightly root-bound.

Choose a pot 2 to 3 cm wider than the old one, which must have drainage holes. Our clear, perforated pots for observing roots after repotting are ideal: their transparency makes it easy to monitor root recovery without disturbing the plant.

We recommend our highly draining substrate formulated for Hoyas, designed for root oxygenation and healthy growth.

1. Gently remove the plant from its pot, tapping the pot if necessary.
2. Gently untangle the roots if they are very compact, without breaking them.
3. Place a layer of substrate, position the plant upright, and fill in without burying the crown.

Important tip 🌿After repotting, water to help settle the substrate. Repotting every two years is sufficient.

The Hoya Lacunosa sp Laos is fertilized every 2 to 3 weeks from March to October, with a liquid fertilizer diluted in the watering water.

From November to February, reduce fertilization significantly or stop it. This is the vegetative rest period, and the winter dryness associated with the cessation of fertilization promotes flowering in the return of spring.

A well-dosed supply promotes:

• denser and well-colored foliage,
• steady growth,
• and better plant resistance.

In the Hoya Lacunosa sp Laos, a slightly richer potassium fertilizer at the end of summer can stimulate the production of the fragrant flower umbels characteristic of the species.

👉 For better results, we recommend our liquid fertilizer specially formulated for Hoyas, easy to dose, with quickly visible results.

Important tip 🌿Never fertilize in a dry substrate: this could burn the roots. Water first, then apply the fertilizer 2 to 3 days later.

Water the Hoya Lacunosa sp Laos when the substrate has dried out thoroughly, which is approximately every 10 to 14 days in summer and every 15 to 21 days in winter. Use room-temperature water.

How do you know when to water?

The finger test remains the most reliable method: insert your index finger 2 to 3 cm into the substrate. If the substrate is dry, it is time to water.

Thanks to its thick, fleshy foliage, the Hoya Lacunosa sp Laos stores water reserves in its leaves, allowing it to tolerate periods of drought without damage, unlike tropical plants with thin leaves.

Important tip: If in doubt, wait rather than watering. Plants tolerate a lack of water better than an excess, which causes root rot.

The Hoya Lacunosa sp Laos is propagated by stem cuttings, ideally in spring or early summer when growth is active.

Preparing the cuttingTake a healthy stem with at least 2 nodes and 2 to 3 leaves, making a clean cut below a node using our stainless steel straight-tip pruning shears. Remove the lower leaves, leaving only those at the top.

1. Let the cut callus for 1 to 2 hours in the open air before planting or placing it in a rooting medium.
2. Place the cutting in our transparent propagation pots containing moist sphagnum moss, or directly into slightly moistened Hoya potting mix.
3. Place in a warm, bright location, ideally between 22 and 26°C, avoiding direct sunlight.

The live sphagnum moss is the preferred rooting medium for Hoyas: it maintains constant moisture without suffocating the roots. For transplanting, use our premium well-draining Hoya potting mix.

Important tip 🌿Rooting generally takes 3 to 6 weeks. The first roots visible through the transparent pot indicate that the cutting is ready to be transplanted.
