Ways to Water Plants While Away: 7 Methods
There are more ways to water plants while away than most people realise — some bought, some improvised, some genuinely reliable and some closer to wishful thinking. This guide lays out seven realistic ways to water plants while away, explains how each one works, and ranks them so you can match a method to your trip without trial and error on your actual plants.
THE SHORT VERSION
01 · THE PRINCIPLE
What every way has in common
Every way to water plants while away is trying to solve the same problem: release a fixed reservoir of water slowly enough to last days or weeks. The ways differ entirely in how well they control that release. Methods that release based on soil moisture are reliable; methods that release on air pressure or gravity alone are erratic.
Once you see this, ranking the ways is straightforward. A terracotta spike and a buried olla release through porous clay as the soil dries. An adjustable dripper releases at a set rate. A wick draws water by capillary action at a roughly steady but unadjustable pace. Globes and bottles release on air pressure, and a pre-trip soak doesn’t release at all — it just front-loads. The best ways control the rate; the worst leave it to chance.
02 · BY TRIP
Which way suits your trip?
For a week or two with normal pots, the terracotta spike is the way — its 10–16 day reservoir matches the trip. For a mixed collection, the adjustable dripper’s per-plant tuning is the way. For large pots or three-plus weeks, the buried olla’s 20–35 day capacity is the way.
For a weekend, almost any way works, including a wick, a globe, or just a deep soak — the short duration forgives a lot. Match the way to your trip length and pots, and the choice among these seven becomes obvious rather than overwhelming.
03 · THE OPTIONS
Seven ways, ranked
Here are seven realistic ways to water plants while away, ranked by how well each controls its release.
01 · Terracotta watering spike
Most reliable
Self-regulating clay, no power. The AcquaTerra’s 17.5 oz reservoir lasts 10–16 days. The best all-round way.
02 · Buried olla
Longest lasting
A 1.25-gallon Acqua Olla waters 20–35 days — the way to go for large pots and long trips.
03 · Adjustable dripper
Most precise
The Dynamic Dripper’s valve sets flow per plant, 4 to 30 days — the way for mixed collections.
04 · Wicks, globes, bottles
DIY & short trips
A wick is a serviceable DIY way; globes, bottles, and a deep soak suit weekends but not longer trips.
The controlled-release trio — spike, olla, dripper — lead; the wick is a serviceable DIY way; globes, bottles, and a soak are short-trip compromises.1 Pick from the top and match it to your pots.
04 · THE SETUP
Setting up the most reliable way
The most reliable way for most people, the terracotta spike, sets up in about five minutes per pot. Its 17.5 oz reservoir covers 10–16 days; scale to an olla or dripper as pot size or trip length grows.
01 · Soak the spike
Submerge the terracotta in water for 15 minutes to prime the porous clay before installing.
02 · Water the pot
Give the plant a normal thorough watering first. The spike maintains moisture — it doesn’t rescue dry soil.
03 · Make the hole
Use the included wooden dibber to open a hole near the pot edge, away from the main stem and roots.
04 · Insert & fill
Seat the spike, firm the soil around it, then fill the 17.5 oz reservoir to the top.
05 · Cap & group
Close the lid to keep bugs out, then group pots together out of direct sun to slow water loss.
For longer trips
Two weeks or more? Run two spikes per pot and move plants away from windows to extend the reservoir.
05 · THE PREP
A pre-trip checklist
Whichever way you choose, these adjustments lower water demand so it lasts longer. They apply across every method.
- Move plants out of direct sun. Bright indirect light keeps plants alive without driving the rapid transpiration that empties a reservoir early.
- Lower the thermostat a few degrees. Cooler rooms transpire more slowly, so the same reservoir lasts noticeably longer.
- Group pots together. Clustered plants raise the humidity around one another, slowing evaporation from soil and leaves alike.
- Skip fertilizer before you leave. Don’t feed within a couple of days of departure; concentrated feed in drying soil can scorch roots.
- Water thoroughly on departure day. A self-watering spike maintains moisture; it works best starting from a properly watered pot.
06 · WHEN IT GOES WRONG
Troubleshooting any way
A way that emptied early was under-sized — add capacity or lower demand. A globe that clogged is behaving as globes do; switch to a spike. Soggy soil means over-supply; self-regulating ways avoid this. A wick that delivered unevenly across pots needs one reservoir per pot. Each way has a characteristic failure, and a matching fix.
There are many ways to water plants while away, but only a few control the release reliably. Terracotta spikes, buried ollas, and adjustable drippers lead; wicks are a fair DIY option; globes, bottles, and soaks are weekend compromises. Pick a way from the top of the ranking, size it to your trip and pots, and your plants are covered.
FAQ · COMMON QUESTIONS
Frequently Asked Questions
What are the best ways to water plants while away?
The most reliable ways release a reservoir slowly: terracotta spikes (10–16 days), buried ollas (20–35 days), and adjustable drippers (4–30 days). Wicks are a workable DIY way; globes, bottles, and a pre-trip soak are compromises best reserved for weekends.
What’s the easiest way to water plants while away?
A terracotta spike — pre-soak, insert, fill, done in about five minutes per pot with no power or settings. It’s the lowest-effort way that’s still reliable, releasing water only as the soil dries for one to two weeks per fill.
Is a DIY wick a good way to water plants?
A cotton or nylon wick from a water reservoir into the pot is a serviceable DIY way, drawing water by capillary action. It works for short trips and single pots, but flow is uneven when pots share a reservoir and the open water can grow algae. Spikes are more consistent.
What’s a cheap way to water plants while away?
A DIY wick or a thorough pre-trip soak costs almost nothing for short trips. For reliable longer coverage at low cost, a terracotta spike is a one-time purchase that covers 10–16 days per fill — cheaper over time than per-visit services or disposable solutions.
Can you water plants with a bottle while away?
An upturned bottle is a common improvised way, but it releases on air pressure — emptying fast in dry soil or stalling in damp. It suits a weekend at most. Fitting the bottle to a terracotta spike controls the release far better and extends it to one to two weeks.
Which way lasts the longest?
A buried olla lasts longest of the passive ways — its 1.25-gallon reservoir releases over 20–35 days. Terracotta spikes cover 10–16 days; adjustable drippers span 4 to 30 days. Globes, bottles, and wicks generally last only a few days to a week.
What way is best for a mix of plants?
An adjustable drip system, because each dripper can be tuned to its plant’s thirst — ideal when pots have very different needs. For uniform collections, multiple terracotta spikes are simpler and equally reliable since they self-regulate automatically.
Is a pre-trip soak a reliable way?
Only for drought-tolerant plants on trips of a few days. A soak front-loads water that drains and evaporates within hours to a couple of days, so it can’t sustain thirsty plants or longer trips. Beyond a long weekend, a slow-release way like a spike is needed.
