Watering can sprinkling water over garden plants

Most gardeners start with a hose or watering can. As the garden grows, watering takes longer every summer and the question comes up: is drip irrigation worth it?

Side-by-side comparison

Drip irrigation Hand watering
Water efficiency About 90%: water goes straight to roots 60–80%: some runs off or evaporates
Time each week Minutes once set up, none with a timer Can be hours in summer
Upfront cost Typically $50–$200 for a home garden Almost nothing
Disease risk Low: leaves stay dry Higher if leaves are wetted
Flexibility Fixed layout Water anything, anywhere
Consistency Very even Depends on the person

When drip wins

  • Vegetable rows and raised beds watered several times a week.
  • Hot, dry climates or areas with watering restrictions.
  • Gardens you need to leave for holidays.
  • Crops prone to leaf diseases, such as tomatoes and squash.

When hand watering is fine

  • A few pots or a small bed.
  • New sowings that need gentle, frequent sprinkles.
  • Gardens that change layout every season.

The best of both

Many gardeners put permanent beds on drip and hand-water pots and seedlings. A tap timer on the drip system handles the bulk of the work.

Planning a drip system

  1. Measure your rows or beds and decide how many drip lines each needs.
  2. Choose emitter spacing: about 30 cm (12 in) for close-planted crops.
  3. Check your tap’s flow so you know how many emitters one zone can run.

Our drip irrigation planner counts emitters, tubing and fittings and tells you how many zones you need. Then use the drip emitter calculator to set run times per plant and the drip flow rate calculator to check your tubing can carry the flow.
