Why Is My Pothos Not Growing? (7 Common Reasons + Easy Fixes)
Pothos is famous for fast growth—so when yours seems “stuck” (no new leaves, tiny leaves, or long bare vines), it’s frustrating, especially as a beginner.
The good news is that pothos usually stops growing for very predictable reasons. Most of them are easy to fix once you identify what’s happening in your home: light, watering, pot/roots, and nutrients are the big ones.
This guide covers the 7 most common reasons pothos doesn’t grow, how to spot each one, and what to do next.
Example: “I thought my pothos was slow-growing, but it turned out it was simply too far from the window.”
First: What Counts as “Not Growing”?
Before troubleshooting, check what you mean by “not growing,” because pothos growth can look different depending on the season and variety.
Signs your pothos is truly not growing
- No new leaves for 4–8+ weeks during spring/summer
- New leaves are much smaller than older leaves
- Long gaps between leaves (leggy growth)
- Stems look healthy but don’t extend or branch
Normal slow periods
- Winter: Many houseplants slow down due to lower light and cooler temperatures.
- After repotting: Some plants pause briefly while roots adjust.
- Newly propagated cuttings: Cuttings often focus on root growth first.
If it’s winter where you live, you may not need a “fix”—you may just need patience and slightly reduced watering.
Quick Diagnosis Checklist (Fast)
Answer these questions first:
- Is your pothos close enough to a window (bright indirect light)?
- Is the soil staying wet for many days after watering?
- Does the pot have drainage holes?
- When did you last repot or refresh the soil?
- Have you fertilized during spring/summer?
- Are there pests (tiny webs, sticky residue, cottony spots)?
- Is the plant too cold or near AC/heater drafts?
Now, let’s go through the common causes.
1. Not Enough Light (Most Common Reason)
Pothos tolerates low light, but it doesn’t usually grow well in low light.
What you’ll notice
- Very slow growth
- Smaller new leaves
- Longer spaces between leaves (leggy vines)
- Variegation fading (Marble Queen/Golden turning greener)
Why it happens
Growth = energy, and energy comes from light. In low light, pothos goes into “survival mode.”
Fix
- Move your pothos closer to a bright window (bright indirect light).
- If you only have low light, consider adding a small grow light.
- Rotate the pot weekly so growth stays even.
Simple rule: If you can easily see a clear shadow of your hand near the plant (but no harsh sunbeam on leaves), that’s often a decent zone for growth.
“My pothos was about ___ feet from the window. I moved it closer and it started pushing new leaves.”
2. Overwatering (Roots Can’t Grow = Plant Can’t Grow)
Pothos often “stalls” when the roots are stressed from staying wet too long.
What you’ll notice
- Yellow leaves (especially lower leaves)
- Drooping even when soil is wet
- Fungus gnats
- Soil feels damp for many days
- Musty smell (possible early rot)
Why it happens
Roots need oxygen. Wet, compact soil holds water and blocks airflow. Stressed roots don’t absorb nutrients well, which slows growth.
Fix
- Let the top 1–2 inches of soil dry before watering again.
- Make sure the pot has drainage holes.
- Consider switching to a better-draining mix (potting soil + perlite).
- If you suspect rot, inspect roots and repot into fresh soil.
3. Underwatering (Growth Pauses When the Plant Is Constantly Thirsty)
Underwatering can also slow growth—especially if the plant repeatedly gets too dry.
What you’ll notice
- Drooping vines/leaves that perk up after watering
- Dry, crispy brown edges
- Soil pulling away from the pot edges
- Growth pauses or new leaves abort
Why it happens
Pothos can survive some dryness, but consistent drought stress makes it conserve energy.
Fix
- Water thoroughly until it drains out of the bottom.
- If the soil became hydrophobic (water runs straight through), bottom-water the pot 15–30 minutes once to rehydrate.
- Check moisture weekly and water when top soil is dry (not bone dry for days).
4. Root-Bound Plant (No Room to Expand)
Sometimes pothos slows down because it’s outgrown the pot.
What you’ll notice
- Roots coming out of the drainage holes
- Water runs through very quickly
- Soil dries extremely fast (thirsty all the time)
- Plant looks healthy, but growth is slow, or leaves get smaller
Why it happens
When roots circle tightly, the plant can’t hold moisture/nutrients as evenly, and it has less space to produce new roots that support new leaves.
Fix
- Repot into a pot 1–2 inches larger (don’t jump too big).
- Refresh soil with a well-draining mix.
- After repotting, keep the light/watering stable and give it a few weeks.
5. No Nutrients Left in the Soil (Needs Light Feeding)
Pothos is not a heavy feeder, but it can slow down if the soil is old and depleted.
What you’ll notice
- Slow growth during spring/summer, even in decent light
- Smaller leaves
- Pale-looking new growth (sometimes)
Why it happens
Potting mixes don’t provide unlimited nutrients. Over time, plants use what’s available.
Fix
- During spring/summer: use a balanced liquid fertilizer at half strength every 4–6 weeks.
- Or top-dress lightly with worm castings (optional).
- Don’t fertilize heavily in winter (many plants are slower then).
Important: Over-fertilizing can cause brown tips and stress. Start light.

6. Temperature Stress / Drafts (Growth Slows When It’s Uncomfortable)
Pothos prefers warm, stable indoor temperatures.
What you’ll notice
- Slow/no growth
- Leaves may yellow or drop if cold stress is strong
- Plant sits near a cold window in winter or under AC/heater airflow
Why it happens
Cold temps slow metabolism. Strong drafts dry the plant or shock it.
Fix
- Keep pothos away from cold drafts and vents.
- Move it a bit farther from a cold window at night in winter.
- Aim for a stable room-temperature environment.
7. Pests (Hidden Growth Killer)
Even a small pest issue can slow growth, especially over time.
What to look for (quick inspection)
- Check leaf undersides and stem joints
- Spider mites: tiny speckling + fine webbing
- Mealybugs: white cottony clusters
- Thrips: silvery scarring, distorted new leaves
Fix
- Isolate the plant
- Wipe leaves
- Treat with insecticidal soap according to label instructions
- Repeat weekly until controlled
If pests are present, don’t expect fast growth until they’re gone.
Extra: Why Your Pothos Has Long Bare Vines (Leggy Growth)
This is common and usually caused by:
- low light
- no pruning for a long time
How to fix a leggy pothos (make it fuller)
- Move to brighter indirect light.
- Prune the longest vines (cut just above a node).
- Propagate the cuttings.
- Replant cuttings back into the same pot for a bushier look.
This is one of the best “beginner wins” because pothos propagates easily.
Step-by-Step “Make It Grow Again” Plan (Simple)
If you want a clear plan, follow this order:
1. Check light first
Move closer to a bright window (bright indirect). This is the biggest driver.
2. Check soil moisture + drainage
If it stays wet too long → reduce watering frequency and improve drainage.
3. Inspect the pot
Drainage holes? Root-bound? Old soil?
4. Feed lightly (in spring/summer)
Half-strength fertilizer monthly.
5. Prune + propagate (optional but powerful)
Encourages branching and a fuller look.
FAQ
How fast should pothos grow?
In good light during spring/summer, many pothos plants produce new growth regularly (often weekly/biweekly). In low light or winter, growth can be much slower.
My pothos is alive but not growing—should I repot?
Only if it’s root-bound or the soil is poor/draining badly. Repotting without a reason doesn’t always help.
Will cutting it make it grow faster?
Pruning can encourage branching and fuller growth, but it won’t replace light. If the plant is in low light, pruning alone won’t solve “no growth.”
Why are new leaves tiny?
Usually low light or nutrient limitation (sometimes root issues). Increase light first.
Conclusion
When a pothos isn’t growing, the cause is usually simple: not enough light, watering issues, root-bound roots, or low nutrients. Start with light and soil moisture, then adjust pot/soil and feeding if needed.
If you want, tell me:
- how far your pothos is from the nearest window, and
- how long the soil stays wet after watering,
