How to Water Plants While You're on Vacation
Keep your houseplants alive while you're away with self-watering setups, wicks, and a few prep tricks. Learn which method fits trips of a weekend, a week, or longer.
Most houseplants tolerate a few days alone with no special effort, but longer trips need planning. The good news is that plants in pots are forgiving if you set them up correctly before leaving: the goal is to slow their water use and provide a steady, modest supply rather than a flood.
This guide covers preparation that buys time for any trip, plus specific watering methods scaled to how long you'll be gone, from a self-sufficient weekend to a three-week absence. Match the method to your trip length and you can leave without worrying.
Step by step
- 1Water thoroughly the day you leave
Give every plant a deep, complete soak so the root ball is fully charged. Let pots drain so they aren't sitting in standing water, which would cause rot in your absence.
- 2Move plants out of direct sun and group them together
Relocate plants away from bright windows and heat sources to a cooler, dimmer spot, which slows their water use dramatically. Grouping them together raises local humidity and reduces evaporation, helping them last longer between drinks.
- 3For a weekend, do nothing more
After a deep soak and a move out of direct sun, most plants are fine for 3-5 days with no further action. Drought-tolerant plants like snake plants and succulents can easily go one to two weeks unaided.
- 4For about a week, set up a wick system
Run a cotton or nylon wick from a water reservoir into the soil; capillary action draws water in as the soil dries. A jug of water set above pot level feeding wicks into several pots keeps moisture-loving plants supplied for roughly 7-10 days.
- 5For longer trips, use self-watering reservoirs
Self-watering planters, plastic globe spikes, or a deep bottom-watering tray can sustain plants for one to three weeks. Test any reservoir method a week before you leave so you know how fast it empties and can size it correctly.
- 6Arrange a backup for trips over two weeks
Beyond two to three weeks, the most reliable option is a friend or neighbor with simple written instructions: which plants to check, the finger test, and to water only when the soil is dry. Leave fewer instructions and clearer ones.
Preparation that buys time for any trip
Before any absence, water deeply, ensure pots drain freely, and move plants out of direct sun into a cooler, dimmer location. Lower light and temperature cut water use sharply, so a plant that drinks weekly in a sunny window might coast for two weeks in a shaded corner.
Grouping plants together creates a humid microclimate as they transpire, slowing the rate each pot dries out. Skip fertilizer before you leave, since you want slower, not faster, growth while you're away.
DIY wick and capillary systems
A wick system uses a strip of absorbent cotton or nylon rope running from a water reservoir into the soil. As the soil dries, capillary action pulls water along the wick, delivering a slow, self-regulating supply. One reservoir can feed several plants with separate wicks.
A capillary mat works similarly: lay an absorbent mat with one end in a water tray and set pots with drainage holes on it, and the soil wicks moisture up as needed. Both methods are cheap, effective for about a week, and worth testing before your trip.
Self-watering products and their limits
Self-watering planters with built-in reservoirs are the most hands-off option and can sustain a plant for one to three weeks depending on reservoir size. Watering globes and spikes work too but empty unpredictably; in fast-draining soil a globe can drain in a day, so always trial them first.
No passive system is foolproof for very long absences. For trips beyond two to three weeks, combine a reservoir method with a check-in from a friend, or accept that drought-tolerant species will fare far better than thirsty ones.
- Test any wick or reservoir method a week before you leave
- Drought-tolerant plants like snake plants need almost no special prep
- Move plants away from sunny windows to slow water use while away
- Write your plant-sitter simple instructions: water only if the soil is dry
FAQ
How long can houseplants go without water?
It depends heavily on the plant. Drought-tolerant species like snake plants, ZZ plants, and succulents can go two to four weeks with no water, while moisture-loving ferns and calatheas may struggle after a week. Watering deeply and moving plants out of direct sun before you leave significantly extends how long any plant can last.
Do watering globes actually work?
They can, but unpredictably. A glass or plastic globe releases water into the soil as it dries, but the flow rate depends on soil density; in loose, fast-draining mix a globe may empty in a day, while in dense soil it can last a week or more. Always test a globe in the actual pot several days before relying on it for a trip.
What's the best way to keep plants watered for two weeks away?
For two weeks, combine preparation with a passive reservoir system. Water deeply, move plants out of direct sun, group them together, and set up self-watering planters, a capillary mat, or wicks fed by a large reservoir. Test the system a week ahead so you can size the reservoir correctly, and ask a neighbor to check thirstier plants if possible.
