Plants don't read your flight itinerary, but most houseplants will happily survive a week or two away with a little preparation. The strategy depends on how long you'll be gone.

- Water thoroughly a day before you go — not the morning of, so excess can drain.
- Move plants out of direct sun into bright, indirect light. Less light = slower water use.
- Group plants together so they raise each other's humidity.
- Remove dead or dying leaves so energy and water go to healthy growth.
- Don't fertilize before leaving — you want slow growth, not a growth spurt.
- Skip the pruning — fresh cuts lose water faster.
3-5 Days
The pre-trip prep above is usually enough. Succulents, snake plants, and ZZ plants don't even need that — a week of dryness is nothing to them. Just move them out of harsh sun.
1-2 Weeks
- Wick watering: thread a cotton or nylon cord from the soil through the drainage hole into a container of water below. Capillary action keeps the soil lightly moist. Test it a few days before you leave.
- Self-watering stakes or bottles: the spike-and-bottle systems work well for larger pots.
- Humidity tray: a shallow tray of water and pebbles under moisture-loving plants (ferns, calatheas) — pot sits on the pebbles, not in the water.
- The bathtub trick: for a cluster of moisture lovers, put a folded towel in the tub, wet it, place pots on it, and leave the curtain mostly closed. Works for up to a couple of weeks.
2+ Weeks
Wicks and trays stretch things, but a houseplant-sitting friend with a one-page instruction sheet is the honest answer. List each plant, where it lives, and its exact watering note ("only when the top 2 inches are dry", "don't water at all"). Most people over-water other people's plants — clear instructions prevent that.
What Never to Do
- Leave pots standing in deep water — that's root rot for almost everything except truly aquatic plants.
- Move plants into a dark room to "slow them down" — they'll drop leaves and decline.
- Over-water 'to be safe' right before leaving — wet feet + closed windows = rot and mold.
Before you go, run any plant you're unsure about through the AI Planter analyzer — the care plan tells you exactly how drought-tolerant it is.
