Monstera obliqua vs Monstera adansonii – Care Guide
These two species are often confused, but they do not grow the same way, and they do not respond to care in the same way. Understanding this early will prevent most of the common problems people encounter.
At a Glance
- Monstera adansonii – adaptable, forgiving, suitable for most indoor growers
- Monstera obliqua – highly specialised, requires stable humidity and careful handling
Light
Both species prefer bright, indirect light. This means good natural light without direct sun on the leaves.
Monstera adansonii will tolerate lower light conditions and continue to grow, although more slowly.
Monstera obliqua is less tolerant. In poor light, it will weaken quickly. In harsh light, it will burn just as quickly. It performs best in a stable, filtered light environment such as a greenhouse or well-lit indoor space.
Watering
The two species differ most noticeably here.
Monstera adansonii should be watered when the top portion of the mix begins to dry. It is reasonably forgiving if allowed to dry slightly between watering.
Monstera obliqua should not be allowed to dry out completely. The root system is fine and delicate, and extended dryness will set the plant back quickly. At the same time, constantly wet conditions will lead to decline. The aim is consistent, light moisture.
Humidity
Monstera adansonii adapts well to average indoor humidity, although it will always perform better with increased moisture in the air.
Monstera obliqua is different. It requires consistently high humidity to remain stable. Without it, growth becomes thin, fragile, and often stops altogether. This is the primary reason it struggles in typical indoor conditions.
Growth Habit
Monstera adansonii is a climbing or trailing plant. It can be grown up a support or allowed to hang. Growth is steady, and the plant will branch and fill out over time.
Monstera obliqua does not behave the same way. It produces long, often leafless runners (stolons), with leaves forming intermittently. This is normal growth, not a sign of poor health.
Because of this, it often appears sparse compared to adansonii, even when healthy.
Potting Mix
Both species require an open, well-draining mix.
A suitable mix should allow air to reach the roots while still holding some moisture. Standard indoor plant mixes can be improved with the addition of bark, perlite, or similar materials.
For Monstera obliqua, this balance becomes more important. The mix should never remain heavy or compacted.
Temperature
Both species prefer warm, stable temperatures and should be protected from cold conditions.
Monstera adansonii will tolerate minor fluctuations.
Monstera obliqua benefits from consistency. Sudden drops in temperature can slow or halt growth.
Common Issues
- Yellowing leaves: Often related to overwatering or poor drainage
- Thin or weak growth: Usually low light or low humidity
- No new leaves (obliqua): Often a result of unstable conditions rather than a single issue
Final Notes
Monstera adansonii is a reliable, adaptable plant that suits most growers.
Monstera obliqua is not difficult in the traditional sense, but it is specific. It responds well when conditions are stable, and poorly when they are not.
If treated the same, adansonii will continue to grow. Obliqua will simply stop.
