Yes, you can put pothos outside in the U.S., but the answer depends on your climate—year-round outdoor growth is limited to USDA zones 10–12, while gardeners everywhere else can move potted pothos outdoors for the warm months and bring them back in before frost.
Pothos (Epipremnum aureum) is a forgiving houseplant, but its tropical origins mean it has real limits when it comes to outdoor life. One wrong placement in full sun or one cold night can ruin weeks of good growth. The good news is that the rules are simple: shade, warmth, and a pot with drainage holes cover most of what you need to know. This article walks through exactly when pothos can go outside, what it needs once it’s there, and how to bring it back indoors without shock.
Which U.S. Climate Zones Can Grow Pothos Outside Year-Round?
Pothos is a tropical perennial that survives winter only where the ground never freezes. In the lower 48, that means year-round outdoor planting is restricted to the warmest parts of Florida, southern California, Hawaii, and coastal Texas. Gardening Know How and Epic Gardening both confirm that pothos is hardy in USDA zones 10 through 12[1][2].
If you live in zone 9 or below, you have two practical choices: keep your pothos in a container and move it outdoors for the growing season, or treat it as a warm-weather annual that dies back with the first frost. The container route is the more popular one, and it works anywhere summer nights stay above 60°F.
What Temperature Range Can Outdoor Pothos Tolerate?
The plant’s comfort zone is 65°F–85°F, and it starts suffering below 60°F[3]. The Sill notes that pothos prefers to stay above 50°F and cannot handle cold[3]. For practical U.S. gardening, that translates to a hard rule: do not leave pothos outside when nighttime temperatures are forecast to drop below 55°F, and never take a chance with frost.
In many northern states, that means the outdoor window runs from late May through early September. In the transition weeks at either end, keep an eye on the overnight low—a single dip to 40°F can blacken the leaves.
Light Requirements for Pothos Outdoors: Shade Is the Rule
Despite being a houseplant that tolerates low light indoors, outdoor pothos needs the opposite treatment: shade to partial shade, or the bright indirect light found under a tree canopy or on a covered patio[1][4]. Direct afternoon sun burns the leaves quickly, turning them pale or crispy within hours[5][6].
The Sill says pothos can handle bright indirect light up to morning direct sun[3]. If you only have a full-sun spot, put the pothos in a location that gets direct light only in the early morning (before 10 a.m.) and shade for the rest of the day. A sheer curtain or a nearby taller plant that filters the sun works well.
| Light Condition | Result for Pothos | Best Placement |
|---|---|---|
| Full direct sun (6+ hours) | Leaf burn, yellowing, curled edges | Avoid |
| Morning sun, afternoon shade | Healthy green growth | East-facing porch or under a tree |
| Filtered/bright indirect light | Strong variegation, compact growth | Covered patio, north side of house |
| Deep shade | Leggy stems, smaller leaves | Minimal—only if no other option |
Watering and Soil: Two Changes for Outdoor Life
Outdoor pothos dries out faster than indoor pothos. Wind, heat, and sun exposure pull moisture from the soil more quickly, so you need to check the pot every 2–3 days in summer and water when the top inch of soil feels dry[5]. Plant Addicts notes that during hot, dry stretches, daily watering may be necessary[5]. Indoors, The Sill recommends every 1–2 weeks; outdoors, that rhythm roughly doubles in frequency[3].
Use a pot with drainage holes and a well-draining potting mix[3][5][6]. ProFlowers warns against letting roots sit in water, and Plant Addicts specifically advises not leaving saucers under outdoor pots because standing water attracts mosquitoes[5][6]. If the pot has a built-in saucer, remove it for the season or empty it after every rain.
How to Harden Off a Pothos Before Moving It Outside
Taking a houseplant straight from a dim living room into the outdoor sun is a recipe for shock. Plant Addicts recommends a gradual transition: start with 1–2 hours in a fully shaded, sheltered spot (like a covered porch), then increase exposure by an hour every day over a week[5].
- Day 1–2: Place in full shade, protected from wind.
- Day 3–4: Move to a spot with morning sun only.
- Day 5–7: Move to its permanent outdoor location (filtered shade).
The after the full week, the leaves should not show any yellow or brown patches. If they do, the plant needs another few days in a shadier spot before you call it settled.
Fertilizer, Pruning, and Growth Habits Outdoors
Outdoor pothos can grow aggressively in favorable conditions—its vines can extend several feet over a single summer, especially if it gets regular fertilizer. The Sill recommends feeding bi-weekly or monthly during spring and summer with a balanced, water-soluble fertilizer at half strength[3]. Patch Plants similarly advises once a month at half strength[7]. Stop fertilizing by September as growth slows for fall.
Prune to control length or encourage branching by cutting just above a node—the bump where a leaf meets the stem[3][8]. Outdoor vines tend to trail over the pot’s edge; if you want a bushier plant, pinch off the growing tips every 4–6 weeks.
Bringing Outdoor Pothos Back Inside for Winter
For gardeners in zones 3–9, the pothos must come inside before the first frost, or when nighttime lows are projected below 55°F[5]. Epic Gardening notes that in cooler temperate climates, pothos can be used as an annual, a greenhouse plant, or moved inside during cold weather[2].
Before bringing it back indoors, inspect the plant and soil for pests—aphids, spider mites, and mealybugs are common outdoor hitchhikers. Rinse the leaves and top inch of soil with a gentle spray of water, then isolate the plant from other houseplants for two weeks to confirm you haven’t brought bugs inside. Cut back any leggy or damaged vines to keep the plant compact through winter.
| Step | Timing | Key Detail |
|---|---|---|
| Move indoors | Before first frost or night lows under 55°F | Err on the early side |
| Pest inspection | Immediately before bringing inside | Check leaf undersides and soil surface |
| Rinse treatment | One time before moving | Gentle water spray on leaves and topsoil |
| Quarantine period | 14 days | Keep away from other houseplants |
Five Mistakes That Kill Outdoor Pothos Fast
- Full sun: Even a few hours of direct afternoon sun can scorch the leaves beyond recovery[5][6].
- Cold exposure: Neglecting to check the overnight low is the single most common reason outdoor pothos dies[1][2][5].
- Overwatering: Frequent outdoor watering is necessary, but roots sitting in water still rot. Drainage holes are non-negotiable[3][6].
- Poor soil or no drainage: Garden soil or a pot without holes guarantees standing water and root disease[3][5][6].
- Skipping the harden-off: Moving a plant straight from indoors to an outdoor spot, even a shady one, often causes leaf drop[5].
