Every fall, as the air turns crisp and the days start to shrink, I feel that gentle nudge of gardener’s panic — the one that whispers, “It’s almost time to bring the plants inside.” Believe me, I’ve learned the hard way that waiting even a few nights too long can mean saying goodbye to a few of my leafy friends.
For many of us, deciding when to bring plants inside for winter isn’t as simple as checking a calendar. It depends on your climate, your plants’ tolerance levels, and even your home’s conditions. Some plants will shrug off a chill; others will wilt the moment temperatures dip below 50°F.
I remember my first real gardening year — I lost my favorite bougainvillea and a tender basil bush because I thought “frost warning” meant light frost. Lesson learned: nature doesn’t always give second chances! Since then, I’ve built my own “bring-in” checklist and chart to make this transition smooth and stress-free.
So today, I’m sharing my complete chart and personal guide on when (and how) to bring your plants inside for winter — from tropical houseplants to hardy perennials and everything in between. Whether you’re gardening in Zone 5 or Zone 10, you’ll walk away knowing exactly what to do — and when.

🌿 Bougainvillea: My Early Frost Heartbreak
Let me start with the one that taught me a big lesson — bougainvillea. I absolutely adore this tropical beauty for its bursts of pink and magenta. But it’s also one of the first plants to suffer when cold sets in.
One year, I waited too long, thinking, “Eh, it’s just a cool evening.” The next morning, my vibrant vine had dropped every single leaf. Now, I bring my bougainvillea inside as soon as night temps consistently drop below 50°F.
If you don’t have room for the whole plant, prune it lightly and let it rest in a sunny indoor spot or enclosed porch. A grow light can make a world of difference.
👉 Tip: Don’t overwater during winter — bougainvilleas go semi-dormant and prefer to stay a bit on the dry side.
(If you’re struggling with bougainvillea not blooming, check out my article “[Why There Are No Flowers on Bougainvillea]” — I promise it’ll help you get those colors back!)
🌼 Geraniums: Easy to Save, Even Easier to Multiply
I’ve overwintered geraniums (Pelargoniums) for years, and they’ve become a tradition in my gardening rhythm. Once nighttime temperatures dip below 45°F, I snip a few healthy stems and root them in jars of water indoors.
By spring, those cuttings turn into lush new plants — and I didn’t spend a penny on replacements. You can also store dormant bare-root geraniums in paper bags in a cool, dark place (around 45–50°F).
👉 Tip: Before bringing potted geraniums inside, trim them back by one-third and check for aphids or whiteflies. A quick rinse with neem oil solution usually does the trick.
🍋 Citrus Trees: Sunshine Lovers with Attitude
My Meyer lemon tree is basically family at this point. But oh boy — it hates cold weather. Once temps fall below 55°F, I start prepping it for the move indoors.
Citrus trees need bright light — at least 8–10 hours daily. Without enough light, they’ll drop leaves in protest. If you don’t have a sunny south-facing window, invest in a good LED grow light.
Humidity is another key — place a humidifier nearby or set the pot on a pebble tray filled with water.
👉 Tip: Don’t fertilize citrus indoors during winter dormancy. Wait until spring growth resumes.
🌈 Coleus: Bright Foliage That Hates the Cold
Coleus is pure color therapy for me. Those patchworks of lime, magenta, and burgundy make any garden corner pop — but they detest cold air.
When nights start dipping below 50°F, I take cuttings from my favorite varieties and root them indoors in water. They grow quickly and stay cheerful all winter on a windowsill.
👉 Tip: Pinch off growing tips to keep them bushy and compact. And don’t panic if older leaves yellow a bit — that’s just adjustment shock.
🌿 Basil: The Sensitive Soul of the Herb Garden
If you’ve ever lost basil overnight, you’re not alone. I swear, basil can sense a temperature drop before you even feel it.
I bring my basil pots inside when nights reach the mid-50s. Sometimes, I’ll start a new batch from seed under grow lights to ensure a steady winter supply.
👉 Tip: Trim often to encourage fresh growth, and keep your indoor basil warm — they hate drafts as much as they love sunlight.
🌺 Begonias: Low-Light Winners Indoors
Begonias transition indoors like seasoned pros — especially the rex and angel wing types. I reduce watering before bringing them in, to help them adapt to indoor humidity levels.
These plants prefer indirect light and temperatures above 60°F. You’ll notice they slow down growth in winter — totally normal.
👉 Tip: Mist occasionally and avoid soggy soil; they dislike wet feet.
🌿 Ferns: Humidity Seekers
Boston and Kimberly Queen ferns are two of my favorite porch fillers. Their fronds are lush, but they’re humidity hogs. When the thermometer reads 45°F at night, I make the move indoors.
Indoors, they’ll crave humidity. Mist daily or run a humidifier. Keep away from heater vents — dry air is their nemesis.
👉 Tip: If fronds yellow after moving inside, it’s a sign of low humidity or light shock. They’ll recover with time and moisture.
🌺 Tropical Hibiscus: The Drama Queen
Ah, hibiscus. Gorgeous, moody, and demanding. When temperatures hit 50°F, I move them inside immediately — even a light chill can trigger leaf drop.
Trim lightly, remove any pests, and place near a sunny window. They might shed some leaves after moving indoors, but they’ll bounce back with stable light and warmth.
👉 Tip: Hibiscus appreciates consistent moisture but not soggy roots. Use a self-watering pot or water deeply, then let it dry slightly.
🌵 Succulents: Quiet Survivors
Succulents are my easygoing winter guests. I bring them in only when nights dip below 40°F. Most handle brief chills, but frost will scar or kill their leaves.
I group them on a south-facing windowsill where they can bask in winter sun. Water sparingly — once every 3–4 weeks is usually enough.
👉 Tip: Rotate your pots occasionally so they grow evenly toward the light.
🌸 Orchids: Graceful Indoors
Orchids are naturally indoor-friendly but still sensitive to cold drafts. I move them away from open windows once temps drop below 55°F.
They actually enjoy stable indoor temps between 60–75°F, with bright, filtered light.
👉 Tip: Never let orchid roots sit in water. Good air circulation is key to preventing rot.
💖 Caladiums: Sleepy Beauties
Caladiums never complain — they just go dormant. When their leaves start yellowing in early October, I gently dig up the tubers, brush off the soil, and store them in dry peat moss in a paper bag.
Come spring, I replant and watch those colorful hearts reappear.
👉 Tip: Keep stored bulbs around 60°F — not in a cold garage or fridge.
🌿 Mandevilla: The Tropical Vine You Can Keep Forever
My pink Mandevilla used to be a “one-season wonder” until I learned it could overwinter indoors. Around mid-October, when nights stay below 50°F, I cut it back by half and bring it inside.
It loves bright, indirect light and benefits from a small trellis for support. By spring, it’s already shooting out new vines.
👉 Tip: Watch for spider mites in winter — a quick neem oil spray every few weeks helps prevent infestations.
🌱 Spider Plants & Pothos: Simple Transitions
These easy houseplants often spend summer outdoors, soaking up fresh air. But once temps dip below 50°F, I move them back inside gradually — first to a shaded porch, then indoors fully.
That gradual acclimation helps them avoid shock from light and humidity changes.
👉 Tip: Trim any sun-scorched leaves and rinse off dust before bringing them in.
🌴 Palms: Keep It Tropical
Areca and Majesty palms bring that resort vibe to patios — but they’re not frost fans. I bring mine in when it’s consistently below 55°F.
They do well indoors if kept humid and away from heater vents. I mist them a few times a week and use filtered water when possible.
👉 Tip: If the tips turn brown, increase humidity and reduce fertilizer.
🍅 Tomatoes: A Fun Experiment Indoors
If you grow cherry or dwarf tomatoes in pots, you can actually bring them indoors and keep them fruiting into early winter.
Move them before nights hit 50°F, and give them a strong grow light for 12+ hours a day. They’ll reward you with small but flavorful harvests.
👉 Tip: Pollinate flowers manually with a soft brush to encourage fruit set indoors.
🌤️ Helpful Notes & Expert Advice
🌡️ Know Your Zone and Microclimate
Always check your USDA Hardiness Zone and your yard’s microclimates. A south-facing porch may stay warmer longer, while open areas frost faster.
A good rule of thumb:
When nighttime lows consistently stay 5–10°F above your plants’ minimum tolerance, it’s time to act.
🪴 Acclimation Matters
Never rush the move. Give plants a transition week — move them to shaded spots before taking them inside. Sudden changes in light and humidity can shock even tough species.
🕷️ Inspect Before You Move
Before carrying anything indoors, check for pests. Wash leaves gently, inspect undersides, and refresh the top inch of soil if needed.
💧 Watering Routine Shift
Indoor winter conditions call for less water and no fertilizer. Most plants go semi-dormant and won’t need as much feeding or moisture.
☀️ Light Is Everything
If your windows face north or east, consider investing in LED grow lights. I use them on timers (14 hours on, 10 off) to mimic daylight cycles.
💨 Air & Humidity
Run a small fan on low setting near plants once a day for airflow. This prevents mold and keeps foliage healthy.
🌻 Final Thoughts: Bringing the Garden Home for Winter
Every autumn, my house slowly turns into a mini jungle again — the bougainvillea climbs by the window, citrus trees line the hallway, and ferns make the bathroom look like a tropical spa. It’s honestly one of my favorite parts of the gardening cycle.
Bringing plants inside for winter isn’t just about survival; it’s about continuing the relationship. You’ve nurtured these living things all year — and now, they get to return the favor by brightening your indoor space through the cold months.
If you’ve made it this far, I hope this guide and complete chart give you the clarity (and confidence) to bring your plants in at the right time — without panic or guesswork.
