Why is my monstera not growing?

The 5 most likely causes

The cause of monstera no new growth usually narrows to one of the items below, ranked by how often we see each in Growli's diagnostic chats. Work down the list — most readers find their answer in the top two.

1. Seasonal dormancy (Likely)
   Most houseplants slow or stop growing from late autumn to early spring as light levels drop. If your monstera hasn't pushed new growth in midwinter, this is usually normal — reduce watering and stop fertilising until day length picks up again.
2. Wrong light level (Most likely)
   Monstera is a high-light plant and quickly turns leggy, pale, or stalled in low light. Move it within a metre of a south or east-facing window, or supplement with a grow light. It wants bright indirect light.
3. Root-bound in its pot (Likely)
   When roots circle the pot, water runs straight through and the plant can no longer take up nutrients. Monstera typically needs a fresh pot every 1-2 years — one size up, not several. If you can see roots through the drainage holes or the soil dries in a day or two, repot.
4. Nutrient deficiency (nitrogen or iron) (Possible)
   If monstera has not been repotted or fed in a year or more, the older leaves can yellow uniformly while the newest growth stays green — a classic sign of nitrogen depletion. Yellow leaves with green veins on new growth point to iron or manganese deficiency. A balanced liquid feed during the growing season usually resolves both.
5. Cold soil or cold water (Possible)
   Tropical plants like monstera stop growing when soil temperature drops below about 18°C/65°F. A draughty windowsill or cold tap water can stall them for weeks. Move to a warmer spot and use room-temperature water.

Why monstera in particular

Monstera is a climber, and a plant left to sprawl with nothing to climb often simply stops pushing meaningful new growth — give it a moss pole and the aerial roots something to grip and it usually resumes. New leaves that emerge small and stay entire, without the signature splits and holes, are the other tell: fenestration develops only as the plant matures under bright light, so a run of unfenestrated leaves generally means too little light, not disease.

Normal turnover, or real trouble?

Monstera keeps its own clock. Through the short, dim days of winter it often parks — no new spears, no visible progress — then wakes as light returns in spring, so an off-season lull is expected, not a fault. Even in growth, a fresh spear can sit for a couple of weeks gathering size inside its sheath before it unrolls. Genuine stalling is no new spear at all across a warm, bright growing season.

How to diagnose in 60 seconds

Run these quick checks before you change anything — the right fix depends on what you find.

• What season is it? Most houseplants pause growth from October to March in the northern hemisphere — that is dormancy, not failure.
• Tip the plant out. Roots circling the pot mean it is root-bound and stalled.
• When did you last fertilise? Plants in fresh potting mix coast for 3-6 months on built-in nutrients, then need feeding.
• Measure light with a phone lux meter app. Below 500-1000 lux at midday is too dim for most monstera.

The fix — step by step

Chase light and support before anything else. A stalled Monstera throwing small, holeless leaves is short of bright, indirect light — move it closer to a good window and give it a moss pole kept lightly damp so the aerial roots can grip and feed into it, which is what unlocks bigger, fenestrated leaves. Don't fertilise a plant that has stopped for want of light or winter warmth; feed cannot stand in for either.

This is the recovery sequence Growli walks users through for monstera with no new growth. Work through the steps in order; skipping ahead is the most common reason a plant fails to bounce back.

1. Confirm it is not just dormancy. Note the season. From mid-autumn to early spring most houseplants — including monstera — pause growth as light drops. If it is the dark half of the year, do nothing and wait.
2. Check light levels honestly. Use a free phone lux-meter app at midday. Monstera needs at least the light suggested by bright indirect light. If you are below that, move it closer to the window or add a grow light.
3. Check if it is root-bound. Tip the plant out. Roots circling tightly mean it is time to repot one pot size up in fresh mix. Don't jump multiple sizes — too much soil holds too much water and triggers rot.
4. Feed during the growing season only. Use a balanced liquid fertiliser at half strength every 2-4 weeks from spring through early autumn. Skip feeding in winter. Over-feeding a stalled plant burns the roots — undershoot rather than overshoot.
5. Be patient with recovery. Even with everything corrected, expect 4-8 weeks before monstera pushes obvious new growth. The first sign is usually a tighter, glossier new leaf rather than a dramatic size jump.

When this can't be saved

Most cases of monstera no new growth are recoverable, but a few red flags point to a plant that has gone past the point of return. If you spot any of these, consider propagating a clean cutting and starting over.

• Stems are softening and leaves are slowly dropping despite "no growth" — the plant is actively dying, not stalled.
• Roots are uniformly brown and mushy when you tip the pot — recovery from this point is rare.
• Multiple growing seasons have passed with no new growth and good conditions — the plant may be terminal.

Prevention

For monstera, the single biggest preventative is matching its native rhythm: when the top 2-3cm of soil is dry, roughly weekly, bright indirect light, and a free-draining pot with a working drainage hole. Plan a yearly repotting check in spring — refresh the top inch of soil even if the pot stays the same — and feed at half strength every 2-4 weeks from spring to early autumn. Track light with a free lux meter app every few months as the sun angle changes through the year.
