Care at a glance

Know your plant

Spots Mysteriosa is a Monstera deliciosa selection. [1]

Monstera deliciosa climbs with aerial roots. Juvenile leaves can be unbroken; the familiar holes and edge divisions develop as the plant matures. [2]

Light and placement

Choose bright indirect light and leave room for climbing growth. If a position changes, increase exposure gradually rather than putting indoor-grown foliage straight into strong sun. [3]

Watering

  1. Allow the upper mix to dry a little before another thorough drink. [3]

  2. Water thoroughly, then empty the saucer. [5]

Soil and pot choice

Use an open, well-drained mix. Choose a container stable enough for the canopy and its climbing support; a very large pot can remain wet too long. [4]

Use a pot with drainage holes. [6]

Temperature and humidity

A warm room and moderate humidity suit indoor Monstera. Keep leaves away from cold drafts; a humidifier can help in very dry air. [3]

Feeding

Feed during active growth at the product label rate; pause when growth slows. [7]

Repotting

  1. Check crowded roots and the stability of the support during active growth. Move to a modestly larger pot when needed and secure the pole before arranging the roots around it. [4]

  2. Keep the original planting depth; settle fresh mix around roots and water in. [8]

Propagation

  1. Choose a healthy piece of stem with a node and, ideally, an aerial root. Cut below the node so that the cutting includes stem tissue, not just a detached leaf. [2]

  2. Root the stem in moist propagation medium, keeping its leaf above the surface. Pot it individually after roots develop. [9]

Pruning and growth

Tie climbing stems gently to a support. If the plant outgrows its space, shorten the stem during active growth; renewed shoots may initially carry smaller, less divided leaves. [4]

Seasonal indoor care

As daylight weakens, review the window position and rotate the pot for even exposure. [12]

In winter, keep the rootball just moist and reduce watering as growth slows. Resume regular feeding when new growth becomes active. [11]

Children and pets

Safety

Monstera foliage can irritate the mouth if eaten. Wear gloves when pruning and keep the plant beyond children’s reach. [3]

Monstera species contain calcium oxalate crystals that can cause oral irritation, drooling or vomiting when pets chew them. [13]

Human poisoning (U.S.): 1-800-222-1222. Medical emergencies: 911. [14]

Pet poisoning: veterinarian; ASPCA 888-426-4435 (consultation fee). [15]

Similar plants

Monstera adansonii is smaller than Monstera deliciosa, with smaller leaves. Both species climb using aerial roots. [16]
