How to Keep Plants Watered While on Holiday

You're off for a week (or two) and the usual worry hits: will the plants survive? The good news is most of them cope far better than you think, especially if you prep your home before leaving. Here are the methods that actually work, from the simplest to the most elaborate.

First: how long will you be gone?

A weekend (2-3 days): almost no plant needs anything. Water well before you go and you're done.
A week: grouping plants plus a simple trick is enough.
Two weeks or more: you need a passive watering system or outside help.

Simple tricks (up to a week)

Group plants away from the sun

Gather all the pots in the coolest room with indirect light, away from sun-facing windows. Clustered together they create a humid microclimate and lose less water. A bathroom with a window is ideal thanks to its humidity.

A deep soak before leaving

Water until it runs out of the drainage holes and let it drain. For thirsty plants, you can sink the pot in a basin for a few minutes so the soil soaks through completely.

Cover the soil

A layer of mulch, coco coir or even pebbles on top of the soil cuts evaporation and holds moisture for several more days.

Passive watering systems (one to two weeks)

Wick or string watering

The most reliable, cheapest method. Place a container of water higher than the pot and run a cotton or felt wick from the water into the soil. The wick slowly releases water by capillary action.

Fill a bucket or jug with water.
Put one end of the wick in the water and bury it a few centimetres in the pot.
Test it a couple of days ahead to fine-tune the flow.

Inverted bottle

Fill a water bottle, make a couple of small holes in the cap, and stick it upside down into the soil. It releases water as the soil dries. Works best in medium and large pots.

Bath or basin with a towel

Lay a wet towel in the bottom of the bath and set the pots on top (no saucers). The towel keeps the base damp and the roots drink what they need. Make sure the pots have drainage holes.

Cones and ceramic systems

Terracotta cones that connect to a bottle are convenient and regulate flow pretty well. A good option if you travel often.

Checklist before you walk out the door

Move all plants out of direct sun.
Water deeply and empty leftover saucers.
Group the pots in a cool, humid spot.
Set up and test your watering system ahead of time.
Remove spent flowers and wilted leaves (they waste water).
Lower the blinds a little to reduce evaporation.

Costly mistakes

Leaving plants in full sun: they'll dry out in two days no matter what system you rig up.
Drowning them "just in case": too much standing water rots the roots — worse than being a little thirsty.
Testing the system the same day: wicks and bottles need adjusting. Set it up two or three days early.

What if I have lots of plants?

Mix methods: succulents and cacti barely need anything, thirsty tropicals deserve their own wick, and for a big collection it might be worth asking someone to pop in once. Remember that in winter the risk is minimal because plants drink very little; review our winter plant care if you're travelling in the cold.

With a little planning, you'll come home to plants as green as you left them. If one greets you looking rough, upload a photo to our AI diagnosis to find out what happened.
