Pro Tips
Mulch over drip line. It keeps soil cool, reduces evaporation, and hides the aesthetic "spaghetti" effect.
In Utah's alkaline water, mineral deposits can clog emitters. Clean the system once a season (late summer) by flushing with extra water.
Group plants by water need. Tomatoes and peppers don't need to share a line with lettuce if lettuce needs more frequent water.
A simple soil moisture meter ($10) saves guessing. Check at 8 AM. If soil is above 50% moisture, skip that day.
Drip irrigation is easiest to install before plants are large. If retrofitting an established garden, lay lines carefully around roots.
Soaker hoses work but clog faster than emitter drip. If budget is tight, use soaker; if you want low maintenance, use drip emitters.
Warnings
Don't skip the pressure regulator. Drip emitters are designed for 20 PSI. At 60 PSI, they'll spray instead of drip.
Don't leave the system running all day. Over-watering roots cause rot and disease, especially in Utah's cool springs. 20–30 minutes 3–4 times per week is usually enough.

Frequently Asked Questions
Do I need a pressure regulator?
Yes. Without one, drip emitters spray instead of drip. It's the single most important component, and it costs $10–15.
How often should I water?
In Utah spring (cool, moist soil), 20 minutes 3x per week is often enough. In summer (hot, fast evaporation), 30 minutes 5–6x per week. Check soil moisture before increasing—over-watering is the #1 cause of root disease.
Can I add fertilizer to the drip line?
Yes, with a fertigation system (an injector that dissolves fertilizer into water). If you're new to drip, start simple. Add fertilizer as a separate soil application.
What happens in winter?
Drain the system before the first hard freeze. Open all valves and run water through to clear tubing. Blow out with an air compressor if you have one. Coiled drip can be stored in a bucket and reused next year.
