About Monstera obliqua 'Sangay Form'
The Monstera obliqua 'Sangay Form' is a delicate climber originating from the montane rainforests of the Sangay region in Ecuador. Unlike more heavily perforated forms, this selection has narrow, oblong-lanceolate leaves that remain largely intact as the plant matures. It thrives in cool, humid environments with filtered light, ascending tree trunks via fine aerial roots. This locality form represents a distinct, stable expression of the species, more entire-leaved than most other obliqua forms.

Before you buy
- Genuine Monstera obliqua leaves are extremely fenestrated (70-90% hole coverage) and paper-thin/near-translucent. Thicker, less extreme fenestration is almost always Monstera adansonii
- Look for leafless exploratory stolons on the plant or cutting. True obliqua produces these before leaves; adansonii does not
- Ask the seller for the specific locality/collection origin. Reputable true-obliqua sellers can usually name it; generic 'obliqua' listings with no origin are a red flag
- Given the price involved, request close-up photos of an actual leaf held up to light before buying, not just a listing photo
Monstera obliqua 'Sangay Form' care
- Substrate
- Very open, chunky epiphytic mix: sphagnum moss, fine orchid bark and perlite. True obliqua roots are fine and easily suffocated or rotted in dense substrate.
- Watering
- Keep consistently and lightly moist; the paper-thin leaves have almost no water storage capacity and desiccate quickly, but waterlogged roots rot just as fast.
- Humidity
- 75-95% is non-negotiable. This species is essentially impossible to grow well outside a closed, humidity-controlled enclosure or greenhouse in a UK home.
- Feeding
- Very dilute liquid fertiliser (quarter strength or less) no more than once a month, since this is an extremely slow-growing plant with minimal nutrient demand.
- Repotting
- Rarely: disturb the root system as little as possible; repot only when the container is genuinely outgrown.
Common problems
Leaf desiccation / crisping
Cause: Humidity below the 75%+ this species requires
Fix: Move into a sealed cabinet or greenhouse. Open-room humidifiers are rarely sufficient for true obliqua
Stem/node rot
Cause: Overwatering combined with dense substrate or poor airflow
Fix: Repot into a very open mix, improve airflow, and reduce watering frequency while keeping ambient humidity high
Mislabelled purchase
Cause: The overwhelming majority of plants sold as 'Monstera obliqua' are actually Monstera adansonii
Fix: Verify fenestration ratio (70-90% hole coverage), leaf translucency, and presence of leafless exploratory stolons before paying true-obliqua prices
Gear for this plant
- Coir Moss Pole, 120cm (4-Pack)Coco coir totem for climbing aroids to root into as they grow upward.
- Natural Rooting Powder, 3 x 75gRooting hormone powder for stem and leaf cuttings.

- Humidity Dome, Heavy-Duty Germination KitVented propagation dome for holding humidity around fresh cuttings.
How to propagate Monstera obliqua 'Sangay Form'
- Methods
- Node cutting. Step-by-step guide
- Difficulty
- Expert Only. Demands precise humidity, temperature, and light control, often a greenhouse or grow tent. Prone to decline outside those conditions.
- Time to establish
- 6-12+ months
- True from cuttings
- Yes. Cuttings keep the cultivar's character.
- Notes
- Notoriously difficult and slow to propagate; single-node cuttings are the norm, and rot rather than rooting is the most common outcome without near-sterile, high-humidity propagation conditions (sphagnum in a sealed box or in-vitro tissue culture).
