Water a Garden While Away: Seven-Day Departure Rehearsal

Use the week before travel as a live acceptance test

The safest way to prepare an existing garden-watering system is to run it exactly as intended for seven days while someone is still present to observe plants, joints and valve closure.

This is not a universal seven-day watering schedule. It is a seven-day rehearsal calendar. Longer absences need a separate capacity and failure analysis in the two-week holiday plan.

Before day one: define the normal state

List every plant group and its intended method. Photograph:

• the outside tap and controller;
• filter and regulator;
• labelled zone starts;
• final emitter or delivery point;
• normal dry paths and floor areas;
• physical shut-off position.

Record current source flow, programmes and known exceptions. Confirm current manuals are available. The rehearsal cannot detect change without a baseline.

Day 1: inspect roots and simplify groups

Check root conditions at a consistent depth. Group plants by root environment, exposure and delivery method. Move unusual portable containers into a compatible group where horticulturally safe, or plan separate manual care.

Remove empty lines and unnecessary connectors. Secure micro-tubes. Keep service points visible.

Do not decide zones by proximity alone. Use the lawn, bed and pot zoning guide when the map is unclear.

Day 2: measure delivery

Run each zone for a short fixed test. Collect representative output at near, middle and far positions. For sprinklers, use straight-sided catch containers across the area.

Correct blocked emitters, kinks and coverage gaps before changing runtime. Inspect below the soil surface after water has had time to spread.

Record actual delivery and root response. Timer minutes alone are not evidence.

Day 3: inspect every connection and closure

Watch each valve open and close. Use dry tissue on the tap inlet, outlet connections and accessible joints after closure. Repair persistent moisture.

Check paths, doors and buildings for runoff or spray. Re-route unsafe delivery. Confirm the final emitter stops as expected.

Exercise the physical water shut-off and local timer controls. Everyone authorised to respond should know them.

Day 4: run the proposed programmes

Enter conservative schedules based on measured delivery and root observations. Read every programme back to catch the wrong day, time or zone.

Run high-demand zones sequentially when combined demand would reduce pressure. Observe the complete automatic sequence. Do not add a new smart feature simply because departure is approaching.

Check current water-supplier restrictions before scheduling mains irrigation. Automation does not create an exemption.

Day 5: inspect the next-day result

Check root conditions before the next run. Look for dry final positions, saturated pots, puddling, runoff and displaced tubes.

Change only one variable per zone: runtime, frequency, emitter position or plant grouping. Record the reason. If several variables change together, the rehearsal cannot show which fixed the problem.

Review greenhouse ventilation and shading separately; outdoor rain may not reach enclosed crops.

Day 6: test recoverability

Use safe, reversible tests:

• operate each valve locally without the phone;
• confirm what happens when remote access is unavailable;
• pause and restore one zone;
• verify the gateway's normal position;
• inspect the battery indicator defined by the manual;
• rehearse physical isolation.

Do not deliberately create a leak or run a pump dry. The aim is to prove response paths, not manufacture damage.

Day 7: freeze the configuration

Run the exact departure sequence one final time. Confirm:

• correct valves open;
• representative final outlets deliver;
• valves close fully;
• paths remain safe;
• root conditions are acceptable;
• forecast and supplier notice have been checked;
• fallback access and contact details are current.

Do not make discretionary hardware changes after this run. A late adaptor or emitter has no rehearsal history.

Do not solve a late problem by hiding it

During the final week, do not double every runtime after one hot afternoon, add an untested splitter, replace all batteries without checking the manual, move the gateway to a convenient but untested socket or accept a slow leak because it lands on soil. Each action removes evidence gathered earlier.

If a safety or delivery fault appears late, fix it and repeat the affected test. When there is not enough time to establish confidence, simplify the system, move vulnerable plants, arrange direct care or close that zone. Departure time is not an acceptance criterion.

Leave an exception card

Provide a local contact where possible with:

• access arrangements;
• normal-state photographs;
• shut-off location;
• zone names matching physical labels;
• specific conditions that require intervention;
• measured rescue-watering instruction;
• your contact and an alternative.

The helper should be able to close water or deliver a defined rescue amount without learning the entire system.

For rented, shared or holiday-let property, confirm access and responsibility under the relevant agreement. Do not assume someone may enter because irrigation is running.

What remote control can and cannot do

Remote control can show recorded status, send a pause and alter a programme. It may help after a forecast change. It does not prove:

• the tap remains open;
• a valve physically moved;
• the filter is clear;
• a tube remains attached;
• the final plant received water;
• the garden has not developed a leak.

Use remote status alongside physical commissioning and human recovery.

Where Johgee fits

Johgee's four-zone RF timer can separate compatible plant groups when its published pressure, flow and radio path fit the installation.

The seven-day rehearsal applies regardless of controller brand. A smart timer does not shorten the evidence period or guarantee unattended operation.

How this guide was prepared

The former page duplicated the two-week holiday text. This revision owns the seven calendar days immediately before departure and assumes the main system already exists. It requires measured delivery, observed shut-off and a frozen final configuration, without claiming that seven days predicts all weather or removes the need for fallback access.
