Hoya Sigillatis Round Leaf

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

In its natural habitat, this epiphytic Hoya grows beneath the canopy of Borneo's rainforests, filtering light through the tree foliage. Indoors, replicating this soft yet generous light is essential to preserving the intensity of the silvery speckles on its leaves. Too much darkness gradually fades these characteristic markings and significantly slows growth.

In summer, make sure that direct afternoon sunlight doesn't reach the leaves, as their fleshy texture makes them susceptible to scorching. In winter, move the plant closer to the window to compensate for the reduced sunlight.

Important tip 🌿Avoid locations near cold drafts or radiators, which dry out the leaves and weaken the plant. For rooms with low light, ourhorticultural lamp suitable for indoor plantsoffers a full spectrum that supports the growth of Hoya Sigillatis Round Leaf all year round, without harmful UV rays.

Hoya Sigillatis Round Leaf is considered moderately toxic to cats, dogs, and young children.

Like most plants of the Hoya genus, Hoya Sigillatis Round Leaf contains a natural latex in its stems and leaves. This latex can cause skin or mucous membrane irritation upon direct contact, and mild digestive upset if fragments are ingested.

If ingested by an animal or child, the possible symptoms are generally mild: excessive salivation, slight nausea, or mouth irritation. These symptoms usually resolve spontaneously, but veterinary or medical consultation is still recommended as a precaution.

What precautions should be taken on a daily basis?

It is advisable to place the Hoya Sigillatis Round Leaf out of reach of young children and curious pets, especially on a high shelf or hanging in a planter. Avoid handling the plant without washing your hands afterwards if you have sensitive skin.

With these few simple precautions, the Hoya Sigillatis Round Leaf can absolutely coexist peacefully with your pets and children in a caring home.

The leaves of the Hoya Sigillatis Round Leaf most often turn yellow due to overwatering, lack of light, or 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.

Because of its succulent and fleshy leaves, the Hoya Sigillatis Round Leaf is particularly sensitive to excess moisture at the roots: a substrate that remains waterlogged for too long can quickly lead to diffuse yellowing, even in the absence of visible symptoms on the surface of the pot.

Important tip 🌿One or two old leaves that turn yellow from time to time is perfectly normal and 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 treatmentseffective and without damaging the foliage.

The Hoya Sigillatis Round Leaf is ideally repotted in spring, between March and May, when growth resumes actively.

Repotting is necessary when:

• The roots emerge through the drainage holes.
• Growth is slowing significantly 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 Sigillatis Round Leaf develops a fine and relatively sparse root system for a climbing Hoya, and it appreciates being slightly root-bound in its pot, which can stimulate flowering. Therefore, choose a pot only 2 cm wider than the old one, and make sure it has drainage holes. Ourtransparent pots to monitor root developmentare ideal: their transparency allows you to easily monitor the condition of the roots after repotting, without disturbing the plant.

Prepare a very well-draining substrate, specially formulated for Hoya. We recommend ourComplete range of substrates for tropical plantsDesigned to promote drainage, root oxygenation, and healthy long-term growth. For this species, choose ourEnriched drainage mix for climbing succulentswhich dries 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 untangle the roots if they are 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 and eliminate air pockets. Allow excess water to drain freely. It may take a few weeks for the Hoya sigillatis 'Round Leaf' to resume its normal growth after repotting; this is perfectly normal.

Hoya Sigillatis Round Leaf 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 Sigillatis Round Leaf benefits from a slightly higher potassium supply in spring and summer, a key period to prepare the formation of flower umbels and maintain the intensity of the silver speckles on the foliage.

A well-balanced intake promotes:

• denser, more colorful foliage
• steady and vigorous growth
• and improved resistance to environmental stresses.

👉 For best results, we recommend ourliquid fertilizer formulated for Hoyatailored to the specific needs of this family, with results visible quickly.

Important tip 🌿Never fertilize Hoya Sigillatis Round Leaf in a dry substrate: this could burn the fine roots.Water normally first, then apply the diluted fertilizer 2 to 3 days later, when the soil is slightly moist. Excess fertilizer can cause leaf burn and damage the characteristic speckling of this plant 💚

Water the Hoya Sigillatis Round Leaf when the substrate has dried out completely, approximately every 10 to 14 days in summer and every 21 to 28 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 succulent, fleshy leaves, the Hoya Sigillatis Round Leaf stores natural water reserves, allowing it to survive long periods without watering without suffering. This characteristic makes it particularly tolerant of neglect, but very sensitive to persistent overwatering. It's also best to use soft water, or let tap water sit for 24 hours before use to minimize deposits on the leaves.

Important advice:If in doubt, it's always best to wait a few extra days rather than watering too soon. Hoya sigillatis 'Round Leaf' tolerates occasional drought well, while overwatering quickly leads to root rot that is difficult to correct.

Hoya Sigillatis Round Leaf is propagated by cuttings of semi-woody stems with at least one node, ideally in spring or early summer when the plant is in full growth phase.

Stem cutting methodSelect a healthy, vigorous stem with 2 to 3 pairs of leaves. Cut just below a node, making a clean, straight cut using ourStainless steel blade pruning shears for taking cuttings without damaging the plantThis limits the risk of infection and promotes rapid rooting. Remove the leaves located on the lower part of the cutting to prevent them from rotting on contact with the rooting medium.

1. Allow the cut to air dry for 1 to 2 hours so that the plant heals slightly, which reduces the risk of rot.
2. Place the cutting in ourtransparent pots to monitor root developmentfilled with a slightly damp substrate or directly into thelive sphagnum moss to maintain root moisture, which provides an ideal environment for Hoya.
3. Place the cutting in a warm, bright location, away from direct sunlight, and maintain a constant temperature of at least 20°C.

Once the roots are well-formed and visible through the transparent pot, transplant the cutting into ourpremium substrate adapted to the needs of Hoya, very well draining and enriched to support young roots from the start.

Important tip 🌿Hoya sigillatis 'Round Leaf' typically takes 3 to 6 weeks to root, depending on ambient temperature and light levels. The first signs of success are the appearance of new, small leaves and the cutting's slight resistance when gently pulled. Avoid watering too frequently during this phase; a slightly moist but never soggy substrate is essential for successful rooting.
