Monstera acacoyaguensis aka Monstera Acacoyaguensis

Monstera acacoyaguensis is a moderate-maintenance houseplant. It requires bright indirect light (though it tolerates full sun outdoors in its native range), consistent moderate watering with the top quarter to one-third of soil allowed to dry between waterings, and high humidity. It is a fast grower that needs a sturdy support structure such as a moss pole. Regular pruning, spring repotting as it becomes root-bound, and occasional leaf cleaning are part of routine care.

Adult leaves of M. acacoyaguensis have petioles 40-65 cm long and ovate blades reaching 60-85 cm long by 35-45 cm wide, with distinctive fenestrations from the midrib. As a climbing vine in the genus Monstera, it can reach up to 20 m in height in native habitat. Indoors, growth is substantially more contained, typically 1.8-2.4 m, and the fast growth rate means the plant can outgrow its pot within a few seasons.

Monstera acacoyaguensis is a tropical species that prefers warm temperatures of 15-29°C (60-85°F). It is frost-tender, hardy outdoors only in USDA hardiness zones 10-12. In cooler climates it must be grown as a houseplant and protected from temperatures below about 15°C, which the genus tolerates only briefly.

No notable scent has been documented for Monstera acacoyaguensis — neither its glossy foliage nor its rarely-produced inflorescence is described as fragrant in available botanical sources.

The inflorescence of M. acacoyaguensis consists of a light yellow to cream spathe (25-30 cm wide, 25-35 cm tall) enclosing a yellow cylindric spadix (1.5-2 cm wide, 18-22 cm long). The spathe is unusually persistent for the genus, remaining intact for approximately 20 days, compared to the 2-3 day lifespan typical of most Monstera flowers. Flowers are rarely produced when the plant is grown indoors.

Monstera acacoyaguensis is a distinct species from Mexico and Belize, and should not be confused with M. lechleriana, a South American relative that grows at higher altitudes and shows a different fenestration pattern. The broader Monstera genus contains dozens of species, including the widely cultivated M. deliciosa. No named cultivars or varieties of M. acacoyaguensis are recorded in the consulted sources.

This species is native to lowland tropical forest in southern Mexico and Belize and can be grown outdoors in frost-free climates (USDA zones 10-12). Unusually for the genus, it thrives in full sunlight outdoors. In cooler regions it must be kept as a houseplant or brought indoors before temperatures drop below 15°C.

Prune Monstera acacoyaguensis to manage its size and encourage bushier growth. Remove long, trailing stems and any dead or damaged leaves with clean, sharp tools. Pruning is best done in spring or early summer when the plant is actively growing. Aerial roots can be trimmed or directed onto a support structure rather than removed entirely.

Repot in spring when the plant becomes root-bound — typically every 1-2 years for actively growing plants. Choose a pot one size larger and use fresh well-draining, loamy soil rich in organic matter. Ensure the new pot has good drainage. After repotting, water thoroughly and place in bright indirect light while the plant acclimates.

Wipe the large, leathery leaves with a damp cloth to remove dust, which can inhibit photosynthesis and make the plant more susceptible to spider mites. Clean both surfaces of the leaves. Avoid leaf-shine products, which can clog stomata.

Monstera can be propagated by stem cuttings — take a cutting with at least one node and one aerial root, allow the cut end to callus briefly, then place in moist soil or water until roots develop. Stem tip cuttings root faster than those without growing tips. In the genus, plants grown from cuttings produce fruit in 3-4 years, versus 6-8 years from seed.

Yellowing leaves in Monstera most commonly result from overwatering; the soil should be allowed to dry partially between waterings. Other causes include insufficient light, nutrient deficiency, or root rot from poor drainage. Check soil moisture before watering and ensure the pot drains freely.

Brown leaf tips and edges typically indicate low humidity, underwatering, or salt accumulation from fertilizer. Monstera prefers high humidity; in dry indoor environments, use a humidifier or a pebble tray with water. Flush the soil periodically to prevent salt build-up.

Drooping or wilting leaves in Monstera usually signal either underwatering or, paradoxically, overwatering with consequent root rot. Check soil moisture: if the soil is bone dry, water thoroughly; if it is soggy, allow it to dry out and inspect roots for rot. Heavy, unsupported stems can also droop — provide a moss pole or trellis for support.

Leaf drop in Monstera is typically caused by cold drafts, sudden temperature changes, or severe underwatering. The plant is tropical and sensitive to temperatures below 15°C. Avoid placing it near air conditioning vents or cold windows in winter.

Monstera is a fast-growing genus under optimal conditions. Slow growth usually indicates insufficient light, low temperatures, underwatering, or being severely root-bound without repotting. Providing a support structure for climbing, bright indirect light, and warm temperatures will encourage vigorous growth.

Monstera is susceptible to spider mites (especially in low humidity), scale insects, mealybugs, and fungus gnats (from overwatering). Root rot can develop in waterlogged soil. Inspect the undersides of leaves regularly and treat infestations early with insecticidal soap or neem oil. Maintain adequate humidity to deter spider mites.

The inflorescence of M. acacoyaguensis consists of a spathe and spadix typical of the Araceae family. Pollination in Araceae is generally carried out by insects (beetles and flies attracted to the spathe), though no species-specific pollinator data was found for M. acacoyaguensis. Indoor plants are unlikely to be pollinated.

The ripe fruit of fruiting Monstera species (most notably M. deliciosa) is edible and tastes like a cross between banana and pineapple. All other parts — leaves, stems, roots, and unripe fruit — contain calcium oxalate crystals and are toxic if consumed fresh. Cooking or drying neutralizes the crystals. M. acacoyaguensis is not commonly reported as producing edible fruit in cultivation, and indoor plants rarely flower or fruit.

No medicinal uses are recorded for Monstera acacoyaguensis or for the genus Monstera in authoritative databases. The medicinal rating for the genus is 0/5 per PFAF.

Aerial roots of Monstera species are traditionally used for basketry, rope-making, furniture construction, and weaving in parts of Central and South America. The primary use of the genus, including M. acacoyaguensis, is ornamental — as a houseplant prized for its dramatic fenestrated foliage.

Monstera Acacoyaguensis’s native range is Central America.

Monstera Acacoyaguensis should be watered regularly, allowing the soil to dry out between waterings.

Monstera Acacoyaguensis loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.

To ensure optimal growth, the Monstera Acacoyaguensis prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

The Monstera Acacoyaguensis does not demand additional humidity levels. Water is mostly absorbed by the roots of plants, rather than their leaves, and the best way to provide humidity to your plants is through watering the soil.

Once the Monstera Acacoyaguensis has doubled in size or after a year has passed, it should be moved to a new pot. By replacing the soil with fresh potting soil containing all the vital nutrients, your plant will receive all the sustenance it needs, negating the requirement for fertilizer. It's important to remember that plants get their energy from the sun, not fertilizer.

No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.

During the wintertime, it is common for Monstera Acacoyaguensis plants to go dormant and their growth rate may slow down. Therefore, the amount of waterings should be spaced out more.
