A week or two away shouldn't mean coming home to crispy basil and a sad balcony. The video above demonstrates several easy DIY self-watering systems you can build in minutes, and this guide walks you through the steps and the planning around them. It's written for Greek summers — homes, holiday rentals, and hotels alike — where heat and wind can dry a pot out fast.
Why Greek summers are hard on plants
Between June and September, strong sun, low humidity, and the Meltemi wind pull moisture out of soil far quicker than in spring. A pot that needs water every three days in May can need it daily in August, so a system that works elsewhere may not stretch through a Greek heatwave.
The fix is rarely a single gadget. It's a combination: move plants out of the worst sun, slow down evaporation, and add a steady water source. Get those three right and most plants will coast through a one- to two-week absence.
Match the method to how long you're gone
For a long weekend, a deep soak and some shade are often enough. For one to two weeks you'll want a drip or wick system, or self-watering reservoirs. Beyond two to three weeks, nothing beats a real person — a neighbour, cleaner, or your property manager — checking in once or twice.
If you run a holiday rental or hotel, build watering into the changeover routine so greenery on terraces and in lobbies always looks cared for, never wilted, between guests.
Five ways to water plants while you're away
- 1
Group, shade, and soak before you leave
Cluster pots together in a shadier, wind-sheltered spot — clustered plants create their own humid microclimate and dry out slower. Move sun-lovers out of all-day direct light if you can. Then water everything deeply the morning you leave so the soil is fully saturated as your buffer starts.
- 2
Build an upside-down bottle drip feeder
Fill a plastic bottle with water, pierce two or three small holes in the cap, then invert it firmly into the soil of a medium or large pot. Water seeps out slowly as the soil dries. Test the flow a day or two early: too fast and you'll need fewer or smaller holes, too slow and you'll add one more.
- 3
Set up a wick from a water reservoir
Run a strip of cotton rope or an old shoelace from a jug of water into each pot, burying one end a few centimetres in the soil. Capillary action draws water along the wick at a steady trickle. Keep the reservoir slightly higher than the pots and shaded so the water doesn't overheat or evaporate.

Try a capillary mat or sink-tray method
For several small indoor pots, line a tray or the bottom of a bathtub with a towel or capillary mat, soak it, and stand the pots on top. They sip moisture up through their drainage holes. Keep the room out of direct sun and the towel damp by leaving a shallow film of water in the tray.
- 5
Automate it or ask a person
For longer trips or a whole terrace, a cheap battery timer on a drip line is the most reliable option — set short, frequent cycles for hot weather. For absences over two to three weeks, arrange a neighbour, cleaner, or your Domakihub provider to check in, top up reservoirs, and catch any plant that's struggling.

FAQ
- How long can plants survive without watering in summer?
- In a Greek summer, most potted plants last two to four days after a deep soak before stress shows, and sun-exposed pots can dry within a day. A bottle drip or wick system typically extends that to one or two weeks; beyond that, plan for someone to top up the water.
- Will an upside-down water bottle really work?
- Yes, for medium and large pots. The trick is the hole size: a couple of small pinholes in the cap give a slow, steady release over days. Always test the flow rate a day or two before you leave and adjust the number of holes so the bottle doesn't drain in hours.
- What's the most reliable option for a holiday rental or hotel?
- A battery-powered drip timer on the irrigation line, combined with someone on the ground. The timer handles daily watering automatically, and your cleaner or property manager confirms terraces and lobby plants look healthy between guests — so greenery is never a wilted first impression.
