When attempting to identify one of these plants it is vitally important to remember that it is difficult to distinguish from a Monstera Adansonii. Even professional botanists and gardeners can be deceived into thinking one is the other because they are just so similar, especially when they are young. A few key identifiers to assist in identifying one plant from the other are:

  • Monstera Obliqua leaves are narrow, while Monstera Adansonii leaves are more oval or arrow-shaped
  • Monstera Obliqua leaves have more holes than leaf tissue, while Monstera Adansonii leaves have more leaf tissue than holes
  • Monstera Obliqua leaves have a paper-thin texture, while Monstera Adansonii leaves have a slightly rougher texture

How to Grow Monstera Obliqua from Seed

Typically, these plants are grown from stem cuttings rather than from seedlings.  To grow a Monstera Obliqua from seed, follow these steps:

  1. Purchase seeds from a reputable seller
  2. Soak the seeds in water for 24 to 48 hours
  3. Fill a container with a seed starting soil mix
  4. Plant the seeds in the soil mix
  5. Water the soil so that it is moist but not soggy
  6. Place plastic wrap over the top of the container
  7. Set the container in a warm spot that gets plenty of bright, indirect sunlight
  8. Once sprouts appear above the soil level, acclimatize them to open air
  9. Once the plants are established, move them to a more permanent plant container

How to Propagate Monstera Obliqua

The ideal method for propagating any Monstera plant is via stem cuttings. The steps for doing this are as follows:

  1. Using a sterile cutting utensil, cut off a healthy stem that includes a leaf and a node
  2. Pull off any leaves that are near the bottom of the stem
  3. Place sphagnum moss or potting soil directly on the stem’s node
  4. Moisten the soil with water
  5. Set the plant in a warm spot with bright, indirect sunlight
  6. Water the plant when the top inch of soil is dry
  7. Roots should appear on the plant after a few weeks
  8. Replant the stems in a medium of coco coir until it is more established

Monstera Obliqua Growing Conditions

It is necessary to keep this tropical plant in a place where the humidity levels are at least 85% and the temperatures range between 70 and 85 degrees Fahrenheit.  Since this combination is not a favored environment for most humans, it may be best to supply heat and humidity to this plant via a plant humidifier or a pebble tray.

How to Plant Monstera Obliqua

It is a good idea to repot these plants every few years. This will provide the plant with new, fresh soil that contains nutrients for healthy growth.  The steps for repotting a Monstera Obliqua are:

  2. Create a hole in the soil for the plant to set inside
  3. Carefully remove the plant from its current container
  4. Gently dust off any excess soil from its roots
  5. Set the plant into the hole in the new container
  6. Spread the soil around so that the plant is secure in its new container

  8. Set it in a warm spot with indirect sunlight

Monstera Obliqua Potting & Soil

This type of plant should be potted in soil that is well-draining but able to hold moisture. The soil should contain peat moss, compost, worm castings, bark, and pumice. It is recommended to inquire about the seller’s potting soil mix when the plant is purchased. This is the best way to ensure that the soil is exactly what the plant requires.

Monstera Obliqua Water Requirements

This type of plant needs moist, but not soggy soil and humidity in its air at all times. Its leaves are delicate and should not be allowed to dry out. Setting it next to an air conditioner vent will also cause it to dry out and severely damage the plant.

  • It is being sold by a private collector
  • It is priced extremely high (3 to 4 figures)
