Alocasia Scalprum

Alocasia Scalprum thrives in bright, indirect light, ideally placed 1 to 2 meters from an east or south-facing window, protected from direct sunlight by a light curtain.

In its natural habitat in Borneo, this aroid grows under the dense canopy of the tropical rainforest, where the light is filtered and diffused. Indoors, these conditions should be replicated by avoiding any exposure to direct sunlight, particularly between May and September, which would cause irreversible burns to its leathery, glossy leaves.

In autumn and winter, move the Alocasia Scalprum slightly closer to the light source to compensate for the reduced sunlight. An east-facing position is ideal year-round to benefit from soft, consistent morning light.

Important tip 🌿Avoid cold drafts and sudden temperature changes near windows in winter, as Alocasia Scalprum is particularly sensitive to them.For naturally dark interiors, ourfull spectrum horticultural lampfaithfully mimics natural light, without harmful UV rays, to maintain steady growth all year round.

Alocasia Scalprum is toxic to cats, dogs and young children, due to the presence of calcium oxalate crystals throughout its plant tissues.

These microscopic crystals, called raphides, are released upon contact with mucous membranes during chewing or swallowing. They cause intense and immediate irritation of the mouth, throat, and digestive tract, which can lead to excessive salivation, difficulty swallowing, vomiting, and localized swelling of the lips or tongue.

The toxicity of Alocasia Scalprum is common to the entire genus Alocasia: no part of the plant, neither the leaves, nor the rhizome, nor the stems, is edible in its raw state without processing.

What precautions should be taken on a daily basis?

Keep Alocasia Scalprum out of reach of young children and pets, either on a high shelf or in a room accessible only to adults. If ingested, consult a doctor or veterinarian immediately, specifying the plant involved.

With simple placement precautions, the Alocasia Scalprum can perfectly well coexist peacefully in a home with children and animals.

The leaves of the Alocasia Scalprum most often turn yellow due to overwatering, insufficient light, or a nutrient deficiency.

• If the leaves turn yellow and become soft, the problem usually comes from excess water which causes the beginning of root or rhizome 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.

Alocasia Scalprum tends to naturally sacrifice its oldest leaves when producing new shoots, a phenomenon that is particularly pronounced in winter during its semi-dormant phase.

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 suitable for houseplants.

Alocasia Scalprum is ideally repotted in the spring, between March and May, when growth actively resumes.

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.

Alocasia Scalprum develops a fleshy, compact rhizome that quickly fills the entire pot, which can accelerate the repotting schedule for young plants in the active growth phase.

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 observe root recovery and the condition of the rhizome after repotting, without having to disturb the plant.

Prepare a well-draining and aerated substrate, specially designed for tropical aroids.We recommend ourComplete range of substrates for tropical plants, and more specifically ourwell-draining substrate for Monstera and Araceae, enriched with biostimulants to promote healthy recovery after repotting.

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. Inspect the rhizome and remove any soft or necrotic parts.
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 substrate settle around the roots and eliminate air pockets. Ensure that excess water can drain freely.Repotting is always a source of stress for Alocasia Scalprum: avoid handling it unnecessarily in the following weeks to promote a rapid recovery.

Alocasia Scalprum 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.

Alocasia Scalprum sometimes enters a marked dormancy phase in winter, which may temporarily lose several leaves: in this case, suspend all fertilizer application until the visible resumption of new spring growth.

A well-balanced intake promotes:

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

Important tip 🌿Never fertilize Alocasia Scalprum in a dry substrate: this could burn the roots and rhizome.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 Alocasia Scalprum vigorous and healthy 💚

Water Alocasia Scalprum when the substrate has dried out completely, approximately every 8 to 12 days in summer and every 14 to 20 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.

Alocasia scalpum stores water reserves in its fleshy rhizome, allowing it to tolerate short periods of drought without visible damage to its foliage. However, this characteristic also makes it particularly vulnerable to overwatering, which quickly leads to rhizome rot that is difficult to reverse.

Important advice:When in doubt, it's always better to wait a little longer than to overwater. Alocasia Scalprum tolerates slight drought well, but it doesn't tolerate constantly soggy soil.

Alocasia Scalprum is propagated by rhizome division, ideally in spring, at the time of annual repotting when the plant is in full growth.

Rhizome divisionUnlike climbing aroids, Alocasia scalpum does not produce stems with aerial nodes that can be propagated from cuttings. Its propagation relies exclusively on the separation of rhizomes or bulbils (small secondary bulbs) that develop naturally at the base of the mother plant. Use ourStainless steel blade pruning shears for taking cuttings without damaging the plantin order to make a clean cut between sections of the rhizome, thus limiting the risk of infection and promoting rapid healing.

1. Carefully remove the plant from its pot and identify the well-formed cloves or rhizome sections, showing at least one visible growth point (bud or young rolled leaf).
2. Separate each section with your clean pruning shears and let the cut dry in the open air for 30 to 60 minutes before planting.
3. Install each section in ourtransparent pots to observe root developmentwhich allow the development of the new root system to be monitored without disturbing the young plant.

Use ourEnriched substrate suitable for aerial rootsWhen installing the divisions, ensure that the growth point remains slightly above the substrate surface. Keep the substrate slightly moist but not soggy, in a warm room above 20°C, away from drafts.

Important tip 🌿Rooting a divided Alocasia Scalprum typically takes 3 to 6 weeks, depending on the size of the rhizome and the ambient temperature. The first sign of success is the emergence of a new leaf from the growing point. Avoid watering too frequently during this phase, as the rhizome is susceptible to rot until the new roots are well established.
