Monstera care guide
Monstera deliciosa
Also known as: Swiss cheese plant, Split-leaf philodendron
Pets and children
Considered toxic
Leaves and stems hold calcium oxalate crystals; chewing brings mouth pain, swelling, drooling, and vomiting, so keep it out of reach and consult a veterinarian, or a doctor for a child, if any is eaten.
How often to water Monstera
- Spring–Summer (Mar–Sep)
- Every 7 days
- As a guide, water thoroughly two to three days after the topsoil dries; in midsummer it dries faster, so shorten the gap.
- Autumn (Oct–Nov)
- Every 10 days
- The soil dries more slowly as it cools; wait about three to four days after it dries before watering.
- Winter (Dec–Feb)
- Every 14 days
- Growth stops, so water lightly about a week after the soil dries and keep misting the leaves as a guide.
Light and placement for Monstera
Bright shade to a window with sheer-curtain light is generally right; strong midsummer sun scorches the leaves, and a dim spot gives leaves without splits.
Overwintering Monstera
Overwintering guide: 5°C (41°F) or above
Move it to a bright spot indoors once nights fall below about 10°C; it tolerates around 5°C, but pull it back from the cold glass at night and out of the heater's draft.
Fertilizing and repotting Monstera
Fertilizer
During growth from May to September, give slow-release pellets about every two months or diluted liquid feed roughly every two weeks, and nothing from autumn on.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Monstera
- Overwatering rots the roots and the lower leaves turn yellow.
- Direct summer sun scorches the leaves, leaving brown patches.
- In a dark room it grows leggy, with long stems and small leaves.
Tips for growing Monstera
- Guide the aerial roots to a stake or into the soil instead of cutting them; the plant steadies and the leaves grow larger.
- Wiping the large leaves with a damp cloth clears dust and lets them catch more light.
- If the stems get too long, cut them back from May to July; the cuttings root in water.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
