Monstera Adansonii Care Tips
Size & Growth
Monstera adansonii aka Swiss cheese vine has two leaf forms, like many aroids – juvenile and adult.
This vine has show-stopper foliage and a fast growth rate. Every split leaf gets covered with oval-shaped holes (fenestration).
If grown on a trellis the leaves tend to become larger. It might grow as far as 13′ feet.
When the leaves are mature, they grow as big as 20″ – 30″ inches.
According to botanists, these holes assist the plant in standing up and resisting high winds and allows light to pass through.
It’s great for smaller spaces since it doesn’t grow as big as the Monstera deliciosa.
Flowering and Fragrance
Flowering is not very common if it’s an indoor plant.
The flowers are typically tiny and are situated near the spadix.
The spathe isn’t exactly a flower, but it’s the modified version of a leaf.

How To Propagate The Monstera Adansonii Plant
To propagate a new Monstera plant, it’s best to utilize a root hormone powder with a stem cutting.
- Cut off a vine section with two nodes from the mother plant.
- Place the vine in a glass filled with water till roots emerge.

Keep in mind it takes some time for the root to emerge from the new cuttings.
Therefore, you should be patient and continuously keep them in a warm and moist area.
Bag the cutting so the moisture is sealed in. This will enhance their survival chances.
Once the root system starts forming, transfer the cutting into the soil and soon you’ll have new plants to grow up a totem.
Monstera Adansonii Pests or Diseases

Brown and yellow patches can be caused by salt build-up or alkaline water.
Regular fertilizing can cause salts to accumulate in the soil. Remedy with periodic leaching.
Flush the salts from the soil by slowly running water through the pot until the water runs out clear from the drainage holes.
