Money Plant in Cold Weather: Will It Survive Outside?

The Fundamental Truth: Money Plant Is a Tropical Plant

Epipremnum aureum — the plant most commonly called money plant across India — originates in the tropical forests of Mo'orea island in French Polynesia. It has since naturalised across South and Southeast Asia, thriving in the warm, humid, frost-free conditions of tropical and subtropical climates.

In its native and naturalised habitats, temperatures never drop below 15°C. The plant has no evolutionary history with frost, with frozen ground, or with the cellular stress of near-freezing temperatures. Unlike truly cold-hardy plants — which have developed specific biochemical and structural adaptations to survive ice formation in and around their cells — money plant has none of these mechanisms.

This means that cold kills it at temperatures that many temperate-climate plants shrug off easily. A healthy money plant that would laugh at drought, neglect, and low light becomes extremely vulnerable to temperatures that humans might consider merely "chilly."

The practical implication for Indian gardeners is simple: if you live in a region where outdoor temperatures drop below 10°C at any point in winter, money plant cannot stay outdoors through that period without protection or will not survive. If you live in a region where temperatures stay above 15°C year-round, money plant can be grown outdoors permanently.

Money Plant Cold Tolerance: Temperature by Temperature

Above 20°C: Thriving

This is money plant's comfort zone. At temperatures above 20°C with adequate light and water, money plant grows actively — producing new leaves regularly, trailing vigorously, maintaining lush green or variegated foliage. No cold-related stress at these temperatures. This is the condition most of South India offers year-round.

15°C to 20°C: Slowing Down

At these temperatures money plant continues to function well, but its metabolism begins to slow. Growth rate decreases. The plant produces fewer new leaves per month. Water requirements drop noticeably. In most cases the plant looks healthy and maintains its foliage fully intact — it is simply operating at a reduced rate. This is a normal and acceptable condition for winter survival.

10°C to 15°C: Stressed but Surviving

This is the borderline zone. At these temperatures money plant's growth stops almost entirely. The plant enters a kind of holding pattern, expending energy only on maintenance rather than growth. Leaves may show slight discolouration or a dull appearance. The plant becomes more sensitive to other stressors — overwatering in this temperature range causes root rot much more quickly than in warm conditions, because root metabolic activity is so reduced.

Extended time at these temperatures (weeks rather than days) will weaken the plant, but does not typically kill it. A brief period at 10°C to 12°C — a few cold nights — is survivable for a healthy, established money plant.

7°C to 10°C: Cold Damage Begins

Below 10°C, genuine cold injury begins. The biological mechanisms are complex — chilling injury in tropical plants involves disruption of cell membrane function and metabolic processes, even without ice formation. Money plant exposed to temperatures in this range shows:

• Leaf discolouration — patches of yellow, pale green, or grey on the leaves
• Slow progressive wilting despite soil moisture
• Tip and edge browning that spreads inward
• A generally stressed, unhealthy appearance

Plants that experience repeated nights at these temperatures without daytime recovery in warmer conditions will accumulate damage progressively. An emergency measure of bringing the plant indoors on cold nights and placing it outdoors during warm days may preserve it through brief cold spells in this range.

Below 7°C: Serious Damage

Below 7°C, cold damage in money plant becomes severe and rapid. Cell membranes are significantly disrupted. Leaves begin to show the characteristic dark discolouration (turning very dark green, then black) and waterlogged appearance that signals cell death. Stems become limp. The damage at these temperatures is not recoverable — affected leaves will die and fall.

If a plant is exposed to temperatures below 7°C for an extended period — a full cold night outdoors — the root system in a pot may also be affected, particularly if the pot is small and provides little insulation. Roots dying from cold are as devastating as roots dying from root rot.

At or Below 0°C: Frost Damage

At freezing temperatures, water in money plant cells freezes, forming ice crystals that physically rupture cell walls. This damage is immediate and catastrophic to all exposed above-ground tissue. A money plant that spends a night at or below freezing will typically be entirely blackened and collapsed by morning — every leaf, every stem, reduced to a black, mushy mass.

The root system in the ground may survive hard frost if the ground does not freeze deeply — this depends on soil type, the depth of the root mass, and the duration of the freeze. Pot-grown money plant has much less root insulation and is far more likely to experience total root kill from frost.

Can Money Plant Be Grown Outdoors Permanently in India?

The answer depends on your city and local climate. Here is a region-by-region analysis:

Regions Where Outdoor Year-Round Growing Is Safe

Kerala (all areas): Minimum temperatures in Kerala rarely drop below 18°C even in the coldest months. Money plant can be grown outdoors year-round — on walls, fences, in gardens, on balconies — without cold risk. In the Western Ghats foothills and higher altitude areas, minimum temperatures can approach 10°C during December and January; plants in these elevated locations should be sheltered.

Tamil Nadu coastal areas (Chennai, Coimbatore plains, Madurai): Similar to Kerala in coastal areas. Winter lows stay comfortably above 18°C. Year-round outdoor growing is safe. Higher Nilgiris stations (Ooty, Kodaikanal) see temperatures that can approach freezing — not suitable for outdoor money plant.

Goa: Coastal Goa has mild winters with temperatures staying above 18°C. Outdoor growing year-round is safe.

Mumbai and coastal Maharashtra (Konkan coast): Coastal influence keeps winter temperatures mild. Outdoor growing year-round is generally safe, though occasional cold spells are possible. Plants can remain outdoors but should be monitored during cold fronts.

Andhra Pradesh and Telangana (coastal and southern areas): Coastal Andhra is suitable for year-round outdoor growing. Interior areas see cooler winters; watch temperatures below 10°C.

Regions Requiring Winter Protection or Indoor Overwintering

Delhi, Punjab, Haryana, Uttar Pradesh, Rajasthan (plains): North Indian winters are the clearest case where money plant cannot survive outdoors. Delhi regularly records minimum temperatures of 4°C to 8°C in December and January, with occasional drops close to 0°C. Any money plant left outdoors in these cities during peak winter is at high risk of cold damage or death. Bring all plants indoors by late October and return them outdoors after the risk of cold nights has passed (typically mid to late February).

Madhya Pradesh and Chhattisgarh: Inland position and altitude lead to cooler winters than the coasts. Most locations see temperatures below 10°C at night in December and January. Indoor overwintering is recommended.

Uttarakhand, Himachal Pradesh, Jammu (plains): Even in the foothills and plains of these states, winter temperatures are severe enough to kill money plant outdoors. In hill station towns (Mussoorie, Shimla), temperatures drop well below zero — money plant simply cannot survive outdoors in these areas.

West Bengal (Kolkata and plains): Kolkata winters are mild by North Indian standards (minimum around 12°C to 15°C), but brief cold waves can push temperatures to 8°C to 10°C. Money plant in exposed outdoor positions should be monitored; sheltered positions near south-facing walls are usually adequate protection in most Kolkata winters.

Interior Karnataka (Bengaluru): Bengaluru's elevated position (920 metres) gives it cooler winters than coastal areas. Minimum temperatures of 10°C to 14°C are common in December and January, occasionally lower. Money plant in exposed outdoor positions may show cold stress during the coldest weeks; sheltered positions or brief indoor protection during cold snaps is wise.

Identifying Cold Damage in Money Plant

Recognising cold damage quickly allows you to take the right corrective action. Cold damage has a distinctive appearance that differs from other common money plant problems:

Early Cold Damage (Chilling Injury)

In the first stage — from exposure to temperatures between 7°C and 10°C for extended periods — the damage may be subtle:

• Leaves that look dull, grey-green, or lacking their usual vibrancy
• Slight yellowing that does not follow the pattern of overwatering yellowing (which starts on lower leaves); cold-related yellowing may appear on any leaves, especially those most exposed
• Slightly limp or less turgid leaves despite adequate soil moisture
• Slow browning at leaf tips and edges

At this stage, moving the plant to warmth and reducing watering (never increasing it) gives the plant the best chance to recover.

Moderate Cold Damage

After exposure to temperatures below 7°C or brief exposure to near-freezing temperatures:

• Leaves turning dark — dark green to black, typically starting at tips and edges and spreading across the leaf
• Water-soaked appearance — leaves look transparent or glassy in patches
• Limp, drooping stems that do not recover with warmth
• The affected areas become mushy and soft within 24 to 48 hours

This damage is not reversible. The affected leaves and stems cannot be saved — they must be removed to prevent secondary bacterial and fungal infection from the dead tissue.

Severe Cold Damage or Frost Kill

After frost exposure or prolonged exposure below 5°C:

• The entire above-ground plant collapses — all leaves blackened, all stems limp and mushy
• The plant appears completely dead
• The root system in the pot may or may not be alive depending on pot insulation and duration of cold

In this case the question is whether the roots are alive, not whether the top growth can be saved — it cannot. The recovery procedure is described in detail below.

How to Protect Outdoor Money Plant Before Cold Weather

If you know cold weather is coming — a cold front, an unusual winter cold snap — these steps protect outdoor money plant:

The Best Protection: Move the Plant Indoors

For potted money plants, there is no more effective cold protection than bringing the pot inside before temperatures drop. A plant that is inside is simply not exposed to the cold. This is easy for small pots and requires a little effort for large ones, but it is the only completely reliable protection.

Move the plant before the cold arrives, not during it. Rapidly moving a cold-stressed plant from 5°C outdoor conditions to a warm room can itself cause some thermal shock. Ideally, bring the plant in when temperatures are expected to drop below 12°C.

Position Against a Heated Wall

If moving the plant indoors is not possible, place it against an exterior wall that receives sun during the day and retains heat — typically a south-facing wall. The wall acts as a thermal mass, releasing heat slowly through the night and keeping the immediately adjacent air marginally warmer than the open garden. This can make a meaningful difference for borderline cold snaps (temperatures briefly touching 8°C to 10°C) but offers no real protection against serious frost.

Cover with Breathable Cloth

Covering the plant with a breathable fabric — old cotton sari, hessian burlap, frost cloth — on cold nights traps the heat radiating from the soil and plant and maintains a slightly warmer microclimate around the foliage. Important: use only breathable fabric, never plastic. Plastic traps moisture and creates conditions for fungal disease; it also does not breathe and can cause temperature swings that are harmful in their own right.

The cloth must be removed during the day when temperatures rise, to allow the plant to receive light and air circulation. A cloth left on for days without removal causes etiolation and fungal problems.

Mulch the Root Zone

For potted plants, covering the soil surface with a thick layer of dry mulch — dry leaves, coconut husk fibre, bark chips — provides insulation for the root zone. Cold soil is damaging to roots even when the air above is not quite cold enough to damage leaves. A 5 cm layer of dry mulch significantly slows the rate at which cold penetrates to root depth in a pot.

Water Before a Cold Night (Not During)

Moist soil holds heat much better than dry soil — this is physics. If cold weather is expected, water your outdoor money plant the day before (not during the cold snap). This extra soil moisture acts as a thermal buffer, releasing stored heat slowly through the night. Do not water during the cold snap itself — cold, wet roots are far more susceptible to damage than cold, drier roots.

Group Plants Together

Several pots of plants grouped together create a collective microclimate that is marginally warmer than the surrounding air, as the plants transpire and the group reduces wind exposure. For large collections of outdoor potted plants, clustering them on cold nights is a practical protective measure.

How to Revive Cold-Damaged Money Plant

If your money plant has already been damaged by cold, the approach depends on how severe the damage is.

For Mild to Moderate Cold Damage

1. Move immediately to warmth: Get the plant into a warm room above 18°C as soon as possible. This stops further cold exposure and begins the recovery environment.
2. Do not water: A cold-stressed plant has impaired root function and is highly prone to root rot. Resist the urge to water. Let the soil stay on the dry side for 10 to 14 days.
3. Remove dead and damaged leaves: Using clean, sharp scissors or pruning shears, remove all blackened, mushy leaves cleanly at the stem. Dead plant tissue harbours bacteria and fungi that can spread to healthy tissue. Do not leave damaged leaves hanging on the plant.
4. Do not fertilise: The plant needs time to recover, not a nutrient load it cannot process. No fertiliser for at least 4 to 6 weeks.
5. Provide bright, indirect light: Good light supports the recovery of surviving foliage. Direct, intense sun on a stressed plant can cause additional leaf burn.
6. Monitor for root rot: Over the next 2 to 3 weeks, watch for the signs of root rot — yellowing leaves from the soil level upward, mushy base stems, foul smell from the soil. If root rot develops, treat it promptly. See our root rot treatment guide.

For Severe Cold Damage (All Foliage Blackened)

When the entire above-ground plant has been killed by frost or severe cold, the question is whether the root system is still alive:

1. Remove the plant from the pot and inspect the roots. Living roots are firm and white to cream coloured. Dead roots are brown, black, or grey, and will be soft or mushy when gently squeezed.
2. If any firm, white roots remain — even a small portion — there is hope for recovery. Trim all dead roots cleanly, dust the cuts with cinnamon powder (a natural antifungal), and repot in fresh potting mix.
3. Place in a warm, bright spot. Do not water for 7 to 10 days after repotting to let any cut surfaces dry before being exposed to moisture.
4. Then water very minimally — just enough to keep the soil barely moist, not wet.
5. Over the next 4 to 8 weeks, watch for new growth emerging from any surviving stem nodes. New leaves indicate the root system has survived and is recovering.
6. If no new growth appears after 8 weeks and the roots are entirely dead (all soft and brown), the plant is lost. Take this as a lesson in placement for next year and start fresh with a new cutting or plant.

Cold-Hardy Alternatives to Money Plant for Cold Climates

If you live in a region where cold winters make money plant management difficult, some alternative trailing or climbing plants are more cold-tolerant:

• English ivy (Hedera helix): Genuinely cold-hardy — survives frost and can be grown outdoors year-round even in North Indian winters in sheltered positions. Dark green trailing foliage with some similarity to money plant growth habit.
• Creeping fig (Ficus pumila): More cold-tolerant than money plant; can tolerate brief cold snaps down to around 5°C. Good for sheltered outdoor walls.
• Tradescantia (spiderwort): Some varieties are cold-tolerant and make attractive trailing indoor or outdoor plants in mild winters.
• Heartleaf philodendron: Slightly more cold-tolerant than money plant but still needs protection below 10°C — a modest improvement.

None of these have the same combination of ease, adaptability, and cultural significance that money plant has in Indian homes, but they are practical alternatives if consistent cold makes money plant management burdensome.

The Bottom Line on Cold Weather and Money Plant

Money plant's relationship with cold is not complicated — it is a tropical plant, it does not like cold, and it has clear limits below which it cannot survive. The confusion arises because India spans such a wide range of climates that "outdoor money plant" means something completely different in Kerala versus Delhi.

In South India and coastal regions: grow money plant outdoors year-round with confidence. In North India: treat your money plant as a plant that goes inside in winter, just like you would bring in outdoor furniture before the monsoon. In borderline regions (Bengaluru, interior Deccan, West Bengal): watch the temperature forecast and take protective action during cold snaps.

Money plant is resilient in every way except cold. Protect it from that one vulnerability and you have a plant that will reward you with years of easy, lush growth.
