Drip irrigation for a terrace garden
By Devendra K Jha · updated 2026-09-27
A terrace garden with a tap is well suited to a tap-fed drip kit on a timer. Run the main line along the pot rows, give each pot its own dripper, keep water away from the terrace waterproofing, and use the timer's delay or skip setting through the monsoon.
Check the water source first
Most terraces have a tap fed from the overhead tank. Pressure from an overhead tank is usually enough for a drip kit. If the tap only has supply at certain hours, set the timer inside those hours.
Lay out the pots for the tubing
Arrange pots in rows along the parapet or on stands so one main line can run past all of them. Shorter runs of tubing water more evenly than one long snake across the terrace.
Protect the terrace
Keep pots on stands or trays so water does not sit on the terrace surface, and check that no dripper is left pointing at the floor. Standing water on a terrace can damage waterproofing over time.
Through the seasons
| Season | What to change |
|---|---|
| Summer | Longer runs, early morning, shade net for tender plants |
| Monsoon | Skip or delay on rain days; check drainage holes are clear |
| Winter | Shorter or less frequent runs |
