Keep Plants Alive While on Vacation
Going away? A complete guide to keeping houseplants and garden plants alive while you're on vacation - from a weekend to a month.
A holiday should be relaxing - not spoiled by guilt about thirsty plants or the dread of coming home to a row of crispy corpses. The good news: with a little preparation, most plants happily survive a trip, and even a long absence is manageable.
This guide covers every length of trip, indoors and out. Match the plan to how long you’ll be away.
First: Prepare Before Every Trip
Whatever the length of your trip, do these the day before you leave:
- Water everything thoroughly. Give every plant a deep, complete soak so it starts your trip fully hydrated. If you are unsure how much each plant really needs, our watering calculator can help you gauge it.
- Move houseplants out of direct sun. Direct sun dries soil fast and stresses unattended plants. Shift them to bright indirect light - even drought-lovers. A plant in lower light uses far less water.
- Group plants together. Clustered plants create a shared humid microclimate and slow each other’s drying. Group them in your most stable, draught-free room.
- Don’t fertilize before leaving. You don’t want plants pushing thirsty new growth while you’re gone.
- Do a quick pest check. A small problem can become a big one over weeks - deal with it before you go.
- Remove flowers and any dead/yellowing leaves - they’re a drain on a plant’s resources.
For a Weekend (1-3 Days)
Easy. A thorough watering before you leave is genuinely all that’s needed for almost every houseplant. Move them out of direct sun, group them, and go. Drought-tolerant plants (the snake plant, ZZ plant, succulents, pothos) won’t even notice. Don’t overthink a short trip - and definitely don’t “pre-load” with extra water, which just risks root rot.
For 1-2 Weeks
Now you need a watering aid for thirstier plants. Drought-tolerant plants still cope on a single soak; for the rest, choose one of these:
The bathtub / sink method
Lay a towel in the bath or a sink, run a shallow layer of water, and stand pots (with drainage holes) on the towel. The towel wicks moisture up into the soil. Works well for a cluster of moisture-loving plants for one to two weeks. Use a bathroom with some natural light.
Self-watering: globes and wicks
- Watering globes / spikes - a water-filled bulb pushed into the soil releases water gradually. Cheap, decent for a couple of weeks. Test them a few days before your trip - release rates vary.
- The wick method - run a strip of cotton or capillary “rope” from a reservoir of water (a jug, a bottle) into the plant’s soil. Water travels along the wick as the soil dries. Reliable and easy to DIY. Set one up per pot, test it beforehand.
Self-watering pots
If a plant already lives in a self-watering pot, just fill the reservoir - it’ll manage one to two weeks easily. For thirsty plants you may consider potting them up into self-watering pots before a trip.
The mini-greenhouse trick
Group plants and loosely cover them (or a tray of them) with a clear plastic bag or cover, not sealing it tight. This traps humidity and dramatically slows water loss. Keep it out of direct sun - sun plus a sealed bag cooks the plants.
For 3+ Weeks (Or Frequent Travel)
For long trips, combine methods - and seriously consider help:
- A plant-sitter is the gold standard. A friend, neighbour, or family member who pops in to water is more reliable than any gadget. Leave clear, simple written instructions per plant (“water these three when the soil feels dry; leave the rest alone”) - vague instructions lead to overwatering by a well-meaning helper.
- An automatic drip irrigation system / timer. Small indoor drip kits on a timer, or DIY bottle-drip systems, can keep plants going for long periods. Set it up and test it for several days before you leave.
- Combine a self-watering setup with a sitter who visits once or twice as a backstop.
- Accept some losses. For a very long absence, a few delicate, thirsty plants may not make it. Prioritise - make sure your favourites and your toughest plants are well covered.
For the Outdoor Garden
Don’t forget the garden:
- Mulch thickly. A deep mulch layer dramatically slows soil drying - the best single thing you can do for garden beds.
- Water deeply right before you leave.
- Containers are the vulnerable ones - they dry out fastest. Group outdoor pots together in shade, move them off hot paving, and set up drip irrigation on a timer or ask a neighbour to water them. Pots can’t survive a hot week alone.
- An outdoor tap timer + drip/soaker hose can run the whole garden automatically - ideal for frequent travellers.
- Harvest ripe vegetables and fruit before you go so they don’t spoil or over-mature.
- Ask a neighbour to water containers and pick crops - offer them the harvest in return.
What NOT to Do
- ❌ Don’t drown plants “to compensate.” Overwatering before a trip causes root rot - you may come home to a plant killed by too much water, not too little. Water thoroughly once, normally.
- ❌ Don’t leave plants in direct sun. It accelerates drying and stress.
- ❌ Don’t rely on an untested gadget. Globes, wicks, and drip systems vary - always test for a few days before you depend on one.
- ❌ Don’t give vague sitter instructions. “Look after my plants” invites overwatering. Be specific, per plant.
Quick Reference
| Trip length | Plan |
|---|---|
| Weekend (1-3 days) | Water well, move out of sun, group - done |
| 1-2 weeks | Above + wicks, globes, towel-in-bath, or mini-greenhouse for thirsty plants |
| 3+ weeks | Plant-sitter with written notes, and/or drip system on a timer; combine methods |
| Outdoor garden | Mulch deeply, water deeply, group pots in shade, drip timer or a neighbour |
Frequently Asked Questions
How long can houseplants survive without water?
It varies hugely. Drought-tolerant plants (snake plant, ZZ plant, succulents) easily survive 2-4 weeks. Thirsty plants and ferns may struggle after a week. A thorough watering plus moving plants out of sun covers most plants for a week or more.
How do I water plants while on vacation?
For short trips, one deep watering is enough. For 1-2 weeks, use wicking systems, watering globes, the towel-in-bath method, or a loose plastic cover to slow drying. For longer trips, use a drip system on a timer and/or a plant-sitter.
Can I leave my plants for 2 weeks?
Yes - drought-tolerant plants on a single deep watering, and thirstier plants set up with a wick, globe, self-watering pot, or the bathtub method. Move all plants out of direct sun and group them first.
Should I water my plants extra before leaving?
Water them thoroughly once - but don’t drown them. Overwatering “to compensate” causes root rot; you can return to a plant killed by too much water. One normal, deep soak is correct.
What about my outdoor garden while I’m away?
Mulch thickly, water deeply before leaving, and group containers in shade off hot paving. Set up a drip system on a tap timer or ask a neighbour to water pots - outdoor containers can’t survive a hot week unattended.
