The Monstera Care Bible: Everything You Need to Know

Quick answer: Monstera deliciosa loves bright, indirect light, a well-draining chunky soil, and a deep watering when the top 1–2 inches are dry. Give it a moss pole or support, and fertilize lightly in spring/summer. For a precise schedule tailored to your window direction, pot size, humidity, and habits, use the AI Plant Doctor Tool.

Monstera at a Glance

  • Light: Bright-indirect; a few hours of gentle morning sun is fine.
  • Water: When top 1–2 in (2–5 cm) are dry; water until drainage, then empty saucer.
  • Soil: Airy mix (potting soil + perlite/pumice + orchid bark).
  • Humidity: 40–60%+ helps bigger leaves and splits.
  • Fertilizer: Diluted balanced feed monthly in growing season.
  • Support: Moss pole or trellis for stronger, fenestrated leaves.

Light Requirements

  • Best: Bright, indirect light near east/south windows with sheer curtains.
  • Okay: Medium light (slower growth, fewer splits).
  • Avoid: Harsh midday sun that causes leaf scorch.

Takeaway: More light (without burn) = bigger, more fenestrated leaves.

Watering & Soil

Watering

  • Check the top 1–2 inches; water deeply when dry.
  • Empty saucers after 10–15 minutes to prevent root rot.
  • Less frequent in winter; more frequent in summer.

Soil

  • Use a chunky aroid mix: potting soil + perlite/pumice + orchid bark.
  • Repot every 12–24 months or when rootbound.

Fertilizing & Growth

  • Spring–Summer: Balanced liquid fertilizer at half strength monthly.
  • Fall–Winter: Reduce or pause unless under strong grow lights.
  • Signs you should feed: pale leaves, slowed growth (after ruling out light/water issues).

Support: Moss Poles & Trellises

  • Monsteras are climbers—vertical support encourages bigger, split leaves.
  • Secure stems gently; keep pole slightly moist if using sphagnum.

Pruning & Training

  • Trim leggy growth to shape; propagate cuttings (see below).
  • Rotate the pot every 2 weeks for even growth.

Propagation (Water or Soil)

  1. Identify a node (bump where roots/leaves emerge).
  2. Cut below a node with sterilized scissors.
  3. Root in water (change every 3–5 days) or plant directly in moist mix.
  4. Transplant to soil when roots are 2+ inches (5 cm).

Common Problems & Fixes

Yellowing Leaves

  • Likely: Overwatering, poor drainage, or low light.
  • Fix: Let soil dry more between waterings; improve light; ensure drainage.

Brown Crispy Edges

  • Likely: Low humidity or underwatering.
  • Fix: Increase humidity; water thoroughly when soil is ready.

No Fenestrations (No Leaf Splits)

  • Likely: Insufficient light or no vertical support.
  • Fix: Increase light; add a moss pole/trellis; patience with new leaves.

Root Rot

  • Likely: Constantly wet soil.
  • Fix: Trim mushy roots, repot in chunky mix, adjust watering.

When to Repot

  • Roots circling the pot or poking through drainage holes.
  • Soil dries extremely fast or stays soggy too long.
  • Plant is top-heavy and unstable.

Tip: Size up 1–2 inches (2–5 cm) only; over-potting keeps soil wet too long.

Pests & Diseases

  • Pests: Mealybugs, spider mites, scale—treat with insecticidal soap or neem weekly.
  • Fungal issues: Improve airflow, water soil (not leaves), use safe fungicide if needed.

Monstera FAQ (2025)

How much light does a Monstera need?

6–8 hours of bright-indirect light is ideal. A bit of gentle morning sun is okay; avoid harsh midday rays.

How often should I water my Monstera?

When the top 1–2 inches are dry. Frequency depends on light, pot size, soil, and season—get a personalized schedule with our AI tool.

Why isn’t my Monstera splitting?

Usually not enough light or no vertical support. Increase brightness and add a moss pole; splits appear on newer leaves as the plant matures.

What’s the best soil mix?

An airy aroid blend (potting soil + perlite/pumice + orchid bark) to keep roots oxygenated and prevent rot.
