Monstera Seasonal Care: Exactly When to Repot, Fertilise and Reduce Watering — Month by Month
Monstera Seasonal Care: A Month-by-Month Guide
Monstera deliciosa is not a plant that wants the same treatment year-round. Like most tropical aroids, it operates on a distinct seasonal rhythm — pushing hard through spring and summer, then pulling back as the days shorten. Get the timing right and you get a plant that produces large, deeply fenestrated leaves on an almost predictable schedule. Get it wrong and you end up with yellow leaves in winter and a root-rot problem that started back in November when you kept watering on the summer schedule.
If your monstera is showing yellow leaves, the pattern and position of the yellowing points to the cause — see the full diagnostic guide.
This guide breaks monstera seasonal care into twelve monthly checkpoints, giving you a clear action list for every stage of the year. Whether you’re managing a juvenile cutting or a mature specimen with a well-established climbing structure, the seasonal approach is the same — the scale just differs.
Spring Monstera Care (March–May)
Spring is the most consequential season for monstera. After two to three months of near-dormancy, the plant is ready to grow — and how you respond in March through May will set the tone for the entire year.

March: Coming Back to Life
The change is subtle at first. Somewhere around late February or early March, you might notice a tightly furled new leaf emerging from the centre of the plant — the first sign that the growth engine is switching back on. This is your cue to begin transitioning out of winter mode.
Watering: Increase frequency gradually. If you’ve been watering every 14–21 days over winter, move to every 10–14 days in March as the soil starts drying out faster with improved light levels. The key is still to let the top 3–4 cm dry before watering again — don’t jump straight back to summer frequency.
Feeding: Resume fertilising, but at half-strength for the first application. A balanced liquid fertiliser (20-20-20 or a dedicated houseplant feed) applied once in mid-March gets the plant used to nutrients again without overwhelming it. Full-strength fortnightly feeding starts in April.
Repotting assessment: March is the optimal moment to check whether your monstera needs a larger pot. Lift it gently and check for roots circling the bottom or escaping through drainage holes. Spring repotting gives roots the entire growing season to establish in fresh substrate — repotting in autumn or winter delays this by six months. See the complete process in our houseplant repotting guide.
Pest check: New growth is soft and vulnerable. Spider mites, thrips, and scale insects all target the youngest leaves first. Examine the undersides of any unfurling leaf with a magnifying glass or your phone camera before it fully opens. Catching an infestation in March is a ten-minute job; missing it until May turns it into a month-long battle.
April: The Growth Flush
April is when monstera puts on its most dramatic show. In good conditions — bright indirect light, temperatures above 18°C, consistent moisture — a healthy plant can push a new leaf every three to four weeks at this time of year.
Feeding: Establish the fortnightly feeding routine. Apply a liquid fertiliser with an NPK ratio that includes moderate potassium (promotes root strength and disease resistance) as well as nitrogen for leaf development. Follow label rates — monstera doesn’t benefit from overfeeding, which can cause salt build-up and brown leaf tips.
Moss pole and support: If your plant is producing aerial roots and leaning, April is the time to add or extend a moss pole. The aerial roots on a climbing monstera aren’t decorative — they supply moisture and nutrients when in contact with a moist substrate, and they allow the plant to produce progressively larger leaves as it gains height. Secure new stems loosely with soft plant ties; don’t force them.
Watering: Monitor closely. As temperatures climb and the plant’s transpiration rate increases, the soil will dry out faster than it did in March. Check every five to seven days and water when the top 3 cm are dry.
May: Spring Peak
By May, your monstera should be in full spring mode — ideally producing one new leaf per month minimum, with juvenile plants possibly moving faster.
Getting the timing right is half the battle — see monstera seasonal care.
Watering: In many UK and northern European homes, May marks the transition to the summer watering schedule: checking every five to seven days, watering when the top 3 cm of soil are dry. In hotter rooms or south-facing positions, this may already mean watering every seven to ten days.
Light adjustment: Increase light exposure gradually as the sun strengthens. A monstera that’s spent winter close to a north-facing window may be ready to move to a brighter east or west-facing position. Avoid sudden exposure to direct sun — leaves will scorch.
Pest monitoring: Continue weekly checks on new growth. May also brings fungus gnats as outdoor soil-borne insects become active — if you see small flies hovering near the compost, allow the top layer to dry more thoroughly between waterings and consider yellow sticky traps.

Summer is the monstera’s peak performance window. Given enough light and consistent care, this is when it produces its largest, most elaborately fenestrated leaves.
June: Full Growth Mode
Watering frequency: In typical indoor conditions at 20–25°C, most monstera will need watering every seven to ten days. The exact interval depends on pot size, substrate composition, and room temperature — use the top-3-cm-dry rule rather than a fixed calendar. Always water thoroughly until it drains from the bottom, then empty the saucer after 30 minutes to prevent waterlogging and the root rot that follows.
Fertilising: Continue the fortnightly schedule established in April. Don’t increase the dose in summer — consistency matters more than intensity. If the leaves are dark green and regularly sized, the current regime is working.
Outdoor acclimatisation: Monstera can be moved outside in summer once night temperatures stay reliably above 15°C. Choose a sheltered position with bright shade — beneath a pergola, on a north-facing patio, or under a large tree canopy. Direct summer sun will cause rapid, irreversible bleaching of the leaves. Start with a few hours of morning shade-light, then extend exposure over two weeks. Outdoor placement increases humidity, discourages spider mites, and tends to produce notably larger leaves.
July: High Summer Maintenance
Leaf cleaning: Dust accumulates on the large, waxy leaves through spring and early summer, reducing photosynthetic efficiency by up to 30% (Penn State Extension). In July, wipe each leaf with a damp microfibre cloth — top and underside. This doubles as a pest inspection. Do not use leaf shine products, which block stomata.
Propagation window: June through August is the ideal propagation period. Monstera propagates most reliably from stem cuttings taken just below a node (the point where a leaf meets the stem) with at least one aerial root attached. Place in water or moist sphagnum moss in a warm, bright position — roots typically appear within three to six weeks in summer, compared to ten to twelve weeks in winter. This is also the best time to experiment with related aroids like philodendron, which propagate using the same method.
Watering: In hot weather (above 27°C) or very sunny rooms, your monstera may need watering every five to seven days. Increase checking frequency rather than watering on a fixed schedule.
August: Preparing for the Slowdown
August is the last full month of peak growth. Begin thinking about autumn transition.
Final summer feed: Continue fortnightly fertilising through August. September will mark the start of the feed reduction, so August’s last application is the final full-strength dose of the season.
Last propagation window: If you’ve been planning to propagate, August is your last reliable opportunity for fast root development. Cuttings taken in September will still root but considerably more slowly.
Outdoor plants: If your monstera is outside, begin monitoring night temperatures from mid-August. Below 15°C at night triggers the move indoors — don’t wait for a single cold snap to catch you off-guard.
Autumn Monstera Care (September–November)
Autumn is a transition period, not a sudden halt. The goal is to slow everything gradually — watering, feeding, interventions — rather than making abrupt changes that stress the plant.
September: Winding Down
Feeding: Reduce fertilising to once a month in September. Growth will visibly slow as daylight hours shorten and temperatures drop — the plant needs fewer nutrients when it isn’t actively building new cells.
Watering: Extend the interval between waterings. If you’ve been watering every seven to ten days in summer, move to every ten to fourteen days in September. The soil will dry more slowly as temperatures drop and growth slows.
Bring outdoor plants in: Move any summered-outside specimens back indoors before night temperatures drop below 12°C. Below this threshold, monstera begins to show cold stress — leaf margins darken and growth stalls. Allow two to three days of gradual indoor re-acclimatisation by placing near a door before moving to a final indoor position. Inspect for pests before bringing inside: spider mites in particular hitchhike in from outdoor positions.

October: Steady Reduction
Feeding: Apply one final monthly feed in early October, then stop feeding entirely until March. Applying fertiliser in winter to a dormant plant encourages weak, etiolated growth and risks fertiliser salt burn on roots that aren’t actively growing.
Watering: Move to a check-every-ten-days schedule, watering only when the top 4–5 cm are dry. In a cool room (below 18°C), this may mean watering every fourteen to eighteen days.
Repotting — last chance: Avoid repotting after October. Roots are slowing down and won’t establish in new substrate until spring. If your plant is very pot-bound and you missed the spring window, wait until March rather than risking root disturbance going into winter.
For planting dates in your area, check pruning monstera tools.
November: Winter Preparation
Feeding: No fertilising from now until March.
Position check: As central heating switches on, assess your monstera’s position. Radiators and underfloor heating create warm, dry air currents that desiccate leaves and dry out compost faster than ambient temperature would suggest. Move the plant at least one metre away from any heat source. Check that it isn’t sitting in a draught from a frequently opened window.
Last propagation attempt: If you want to take a cutting before the growing season ends, do it before the end of November. Cuttings taken in December or January will root very slowly and are more vulnerable to rot in the low-light, cool conditions.
Winter Monstera Care (December–February)
Winter is the period when most monstera problems are created. The most common mistakes are watering too frequently (because the schedule hasn’t changed) and overfertilising (because growth has stalled and owners assume the plant needs more). Winter success means doing less, not more.
You might also find reasons monstera drooping and diagnose helpful here.
December: Minimal Intervention
Watering: Allow the top 5 cm of soil to dry completely before watering. In a standard living room at 18–20°C, this typically means watering every 14–21 days in December. In a cooler room or north-facing position, it could stretch to three weeks or more. The danger signal is not “it’s been two weeks” — it’s the soil still feeling damp when you probe with a finger or bamboo skewer. Overwatering in winter is the primary cause of root rot in monstera; if you’re ever in doubt, wait another three days.
Feeding: None.
Humidity: Central heating reduces indoor humidity to 20–35% in many homes, well below the 50–60% monstera prefers. Signs of low humidity include crispy leaf margins and browning leaf tips. Options include a humidifier (most effective), pebble tray with water beneath the pot (modest effect), or grouping plants together. Misting the leaves directly is largely ineffective — the moisture evaporates within minutes and does not reach the roots or increase ambient humidity.
Watering mistakes cause more damage than most pests — monstera has brown tips: causes has the details.
January–February: Maximum Patience
Watering: Continue the minimal winter watering schedule. If your home is heated to above 20°C consistently, soil will dry faster — check every ten days and adjust accordingly.
Light maximisation: January and February are the lowest-light months of the year in the northern hemisphere. Clean the leaves thoroughly with a damp cloth to remove any dust accumulated since the autumn — even a thin layer of dust meaningfully reduces light absorption. If your monstera has been pushed to a darker corner, now is the time to move it to the brightest available position.
Spring and fall planting each have advantages — monstera brown tips covers both.
No repotting: Resist the temptation to repot if you notice roots at the drainage holes. February feels like the start of spring, but wait until March when growth is actively beginning before disturbing the roots.
Monitor for pests: Spider mites thrive in warm, dry winter conditions. Check the undersides of leaves monthly. Early detection means a simple wipe-down with neem oil solution; a missed infestation over two winter months means a major problem by spring.
Fenestration Development Timeline
One of the most common questions about monstera seasonal care relates to fenestration — the distinctive splits and holes that make monstera leaves recognisable. Understanding when and why they develop changes how you interpret your plant’s progress.
Juvenile phase (0–2 years): Young monstera produce entirely solid, unfenestrated leaves. This is normal and not a sign of poor care. Juvenile leaves are heart-shaped and can look almost identical to some philodendron species — a source of frequent misidentification. If you’re unsure which plant you have, the monstera vs philodendron guide covers the key differences.
First fenestration (typically 2–3 years with adequate light): The first splits usually appear at the leaf margins rather than as interior holes — the leaf edge becomes irregular or “lobed” before true internal perforations develop. Adequate light is the critical variable: a monstera kept in dim conditions may stay juvenile-looking for five years or more, while the same plant in bright indirect light will fenestrate on schedule.
You might also find monstera not flowering helpful here.
Full fenestration (3–5+ years): Mature plants receiving good light produce leaves with deep marginal cuts and multiple interior holes. Leaf size also increases substantially — a well-established climbing monstera on a moss pole can produce leaves exceeding 50 cm in diameter.
Seasonal impact on fenestration: Leaves produced during spring and summer — when light and nutrients are most available — are typically larger and more elaborately fenestrated than those produced in autumn. Winter-produced leaves (if any appear at all) tend to be smaller and sometimes revert to simpler form, even on mature plants. This is entirely normal and reverses with the return of good growing conditions in spring.
| Age | Expected Leaf Form | Key Requirement |
|---|---|---|
| 0–1 year | Solid, heart-shaped | Normal juvenile stage |
| 2–3 years | Lobed margins, first perforations | Bright indirect light |
| 3–5 years | Full splits and holes | Climbing support, consistent feeding |
| 5+ years | Very large, deeply fenestrated | Moss pole contact, adequate pot size |

FAQ
Why are my monstera leaves yellow in winter?
Winter yellowing is almost always caused by one of three things: overwatering (the most common cause — roots sitting in wet soil in cold, low-light conditions), a sudden drop in temperature from a cold draught, or too much nitrogen fertiliser applied too late in the year. Check the roots — soft, brown, mushy roots indicate root rot that needs addressing immediately. If roots look healthy and white, adjust your watering frequency and ensure the plant isn’t near a cold window.
Should I mist my monstera in winter?
Misting provides only brief, localised humidity that evaporates within minutes and doesn’t meaningfully raise ambient humidity where the roots and stomata are. It can also leave water droplets that cause fungal spotting on leaves in low-light, low-airflow winter conditions. A humidifier near the plant, or a pebble tray filled with water placed beneath the pot (without letting the roots sit in water), are more effective alternatives.
How often should I water my monstera in summer vs winter?
In summer (June–August), most indoor monstera need watering every seven to ten days in a typical home. In winter (December–February), this extends to every fourteen to twenty-one days. These are guidelines, not fixed schedules — always check the top 3–5 cm of soil before watering rather than following a calendar. Soil drying time varies with temperature, pot size, and light levels.
My monstera hasn’t grown at all this winter — is something wrong?
Probably not. Monstera naturally slows or stops visible growth between November and February in the northern hemisphere as light levels drop. This is normal seasonal dormancy and doesn’t indicate a problem with care. As long as existing leaves look healthy and roots are firm and white, the plant is simply waiting for spring. Focus on keeping conditions stable — consistent temperature, minimal watering, no feeding — rather than trying to push growth with extra fertiliser or more water, which will cause more harm than good.
Can I repot my monstera in autumn?
It’s not recommended. Repotting in autumn disrupts the root system just as the plant is entering dormancy, and the roots won’t be able to establish in new substrate until spring. Wait until March for the ideal repotting window. If the plant is extremely pot-bound and the situation is urgent, repot in early September at the latest — enough growing time remains to settle before winter begins.
Why did my monstera produce a leaf with fewer holes than usual?
Leaves produced in autumn or winter often have simpler fenestration than summer leaves — less light and reduced nutrient availability mean the plant has less energy to invest in complex leaf architecture. This reverses as spring arrives. On younger plants, a sudden reduction in light (moving the plant to a darker position) can cause a similar regression in leaf complexity regardless of season.
