Drip Irrigation for Raised Beds: A $40 Setup With a Timer (Beginner Guide)
Parts list, layout and timer settings. The one upgrade that stops beds dying in July.
Updated 2026-09-10
Why drip
Hand watering is the chore that ends most first gardens by August. A drip line on a battery timer waters at 6am while you sleep, uses less water and keeps leaves dry (fewer fungal problems).
Parts for two 4×8 beds
- Hose-end battery timer
- Backflow preventer and 25 psi pressure regulator (usually included in kits)
- 1/2 in mainline to the beds, 1/4 in drip line or soaker tape in the beds
- Emitters or inline drip tubing at 6–12 in spacing, stakes, end caps, a punch tool
Layout
Run the mainline along the outside of the beds. In each bed, lay drip lines 12 in apart lengthwise (four lines in a 4 ft bed). Containers get one 1/4 in line with a 1–2 gph emitter per pot.
Timer settings
- Spring: 20 minutes, 3 mornings a week
- Summer: 30–40 minutes daily for beds; containers may need a second short evening cycle
- Fall: back to 3 days a week
Check with your finger 2 in down: it should be moist, not wet. Adjust by minutes, not frequency.
Winter
Drain lines, bring the timer indoors, leave the tubing in place.
