Keep Houseplants Alive While Traveling This Summer
Summer is here, and if you’re anything like me, you’ve spent months building out a beautiful indoor jungle — only to suddenly realize you’re booked for a two-week trip and have absolutely no idea what’s going to happen to your plants while you’re gone.
I’ve been there. Last July, I came home from a ten-day road trip to find my favorite monstera drooping dramatically and two of my pothos nearly crispy at the tips. It was heartbreaking — and completely avoidable. That experience sent me down a deep rabbit hole of plant-sitting strategies, and I want to share everything I’ve learned so your summer travels don’t cost you a single leaf.
Why Summer Travel Is Especially Hard on Houseplants
Most people assume that summer — with all its warmth and light — must be great for houseplants. In some ways, yes. But for indoor plants in an apartment or condo, summer travel creates a perfect storm of stress.
When you leave, the air conditioning might run on a timer, or it might not run at all. Temperatures near windows can spike dramatically on sunny days. And without you there to water, monitor, and adjust, even the hardiest plants can suffer faster than you’d expect.
Understanding why summer travel is risky helps you build a smarter plan — not just a “fingers crossed” situation.
Step 1: Take Stock of What You Have
Before you do anything else, walk through your space and categorize your plants by how thirsty they are.
Thirsty plants (ferns, calatheas, peace lilies) need frequent water and will struggle the most while you’re gone. Moderate plants (pothos, philodendrons, monsteras) can go a week or so without attention if properly set up. Drought-tolerant plants (succulents, snake plants, ZZ plants) are your low-drama travelers — they’ll be just fine for a couple of weeks with minimal intervention.
This inventory shapes every decision you make next. Don’t try to apply the same solution to every plant; that’s where most people go wrong.
Step 2: Water Deeply Before You Leave
This sounds obvious, but there’s a right way and a wrong way to do it.
Give every plant a thorough, deep watering the morning you leave — not two days before, and not a quick splash. You want the soil fully saturated so moisture can slowly wick through the root zone over the coming days.
For your thirstiest plants, consider bottom-watering: set the pot in a shallow tray of water for 30–45 minutes so the roots absorb moisture from below. This ensures even saturation all the way through, rather than just the top inch of soil.
Avoid the temptation to overwater “just to be safe.” Soggy, waterlogged soil with no one home to check on it is an open invitation for root rot.
Step 3: Use Self-Watering Tools for Trips Over a Week
If you’re gone longer than five to seven days, a one-time deep watering probably won’t cut it — especially for your thirstier plants.
Self-watering inserts sit in the pot and draw water from a reservoir at a controlled rate. Many plant parents swear by them for medium-length trips.
Terracotta watering spikes connected to a bottle of water work on a similar principle — slow, passive drip delivery right to the root zone. They’re inexpensive, widely available, and genuinely effective for a week to ten days.
DIY wicking systems using cotton rope and a bucket of water can serve multiple plants at once. Run one end of the rope into the water source and bury the other end in the soil. It’s low-tech but surprisingly reliable.
Step 4: Move Plants Away from Direct Windows
This one is counterintuitive for light-lovers, but hear me out.
In summer, a south- or west-facing window can become a heat trap in the afternoon. Without you there to pull a sheer curtain or move a plant back, a full day of direct summer sun through glass can scorch leaves and bake soil dry much faster than usual.
Pull your plants a foot or two back from windows before you leave. They’ll get ambient light without the scorching intensity. If you’re worried about them not getting enough light during your absence, this is exactly where a grow light on a timer becomes your best friend.
Step 5: Put Your Grow Lights on a Timer
I’ll be honest — this is the strategy that completely changed the game for me.
After my monstera disaster, I set up a simple plug-in timer on my grow lights. Now, no matter how long I’m away, my plants get consistent, predictable light every single day. No more relying on variable window sun. No more worrying whether a cloudy week is going to send my tropical plants into a tailspin.
The key word is consistent. Plants don’t need more light while you travel — they need the same reliable light cycle they’re used to. A grow light on a timer replicates your regular routine automatically. Most indoor plants thrive with somewhere around 12–16 hours of light per day depending on the species, but the exact range matters less than the consistency.
If you’re already using grow lights for your indoor setup, just make sure they’re plugged into a timer before you walk out the door. If you’re not using grow lights yet, summer travel is honestly one of the best reasons to start.
Step 6: Group Plants Together
Plants lose moisture through their leaves in a process called transpiration. When you group plants together, they collectively raise the humidity around each other — creating a slightly more stable microclimate that slows moisture loss.
Push all your plants into one corner or cluster them on a table together before you leave. This works especially well for humidity-loving plants like ferns, calatheas, and orchids.
As a bonus, grouping makes it much easier for a plant-sitter to find and water everything if you do have someone coming by.
Step 7: Enlist a Plant Sitter — the Right Way
If you’re going to ask a friend, neighbor, or family member to water your plants, please don’t just say “water them every few days.” That’s how plants get drowned or ignored in equal measure.
Leave a written note (or a voice memo, or a quick video walkthrough) that covers:
- Which plants need water and how often
- How much water each plant needs — a cup? A full watering can?
- What to look for — soil should feel dry an inch down before watering again
- Which plants to leave completely alone (succulents, snake plants, ZZ plants — just tell them not to touch these)
The more specific you are, the better your plants will fare. Most willing plant-sitters are not plant people themselves — they need clear, simple instructions, not botanical jargon.
Step 8: Consider a Humidity Tray for Tropical Plants
A humidity tray is simply a shallow tray filled with pebbles and water, with the plant pot sitting on top of the pebbles (not in the water). As the water evaporates, it raises the humidity immediately around the plant.
This is a low-effort setup that can make a real difference for moisture-loving tropicals over a week or two. It won’t replace watering, but it reduces how quickly plants dry out and stress from dry apartment air — especially if the AC is running constantly while you’re gone.
A Quick Pre-Travel Checklist
Before you zip that suitcase, run through this:
- ✅ Deep-watered all plants the morning of departure
- ✅ Bottom-watered thirsty plants for even saturation
- ✅ Set up self-watering spikes or wicking systems for week-plus trips
- ✅ Moved plants back from direct windows
- ✅ Grow lights plugged into a timer and tested
- ✅ Plants grouped together for shared humidity
- ✅ Left clear written instructions for any plant sitter
- ✅ Humidity trays set up under tropical plants
You Don’t Have to Choose Between Travel and Plants
Learning how to keep houseplants alive while traveling is really about one thing: removing yourself as the daily variable and replacing you with reliable systems.
A timer on your grow lights. A self-watering spike in your fern. A clear note on the counter for your neighbor. These small setups take maybe an hour before you leave, and they’re the difference between coming home to a thriving jungle and coming home to a plant emergency.
I’ve now done week-long and two-week trips with zero casualties — and it feels so good to walk back through the door to a room full of happy, green plants. You can absolutely do the same.
