If you’re starting from zero, read my post with all the instructions for building a raised garden bed.

Starting Simple: The Easiest Way to Water a Garden

I’ll be honest—I’m no gardening expert. I grew up in the desert, where even the weeds struggle. A watering system wouldn’t have fixed all that.

But now that we’re in Omaha, where plants basically volunteer to grow, I decided it was time to fulfill my green-thumb dreams. Installing a drip line system felt intimidating at first, but it ended up being one of the simplest DIY projects I’ve tackled.

Top 5 Reasons to Install a Drip Irrigation System for Raised Beds

Five reasons you should install a drip system for watering raised garden beds:

#1. Stop setting alarms to stand in the sun with a hose—unless you really want to cosplay as a Victorian gardener every morning.

#2. Plants thrive with consistent watering = bigger, better harvests.

#3. Your neighbors do not want to water your garden while you’re on vacation. Trust me.

#4. It uses 30–50% less water than hand watering.

#5. It’s easier than you think—ours took less than half a day!

Step-by-Step: How to Install a Drip Irrigation System for Raised Garden Beds

Step 1: Find the Nearest Water Source for Your Garden

Start by identifying the closest water source to your raised beds. Ours are tucked along the side of the house behind a fence, but distance isn’t a deal-breaker—just plan your tubing accordingly. This is the first step in any drip irrigation system for beginners.

Step 2: Install a Hose Splitter for Drip Irrigation Access

If you’re limited on hose bibs like we are, attach a hose splitter to make room for your DIY watering system for vegetable gardens. This lets you run both a regular hose and your irrigation line from the same spigot.

Step 3: Build the Main Line with Poly Tubing

We DIY’ed our own “hose” using 1/2-inch poly tubing since both ends were just open. I slid an adjustable clamp onto one end, then used a lighter to gently heat the tubing—just enough to soften it. That made it easier to press the hose adapter in nice and snug.

Once it was in place, I tightened the clamp with my drill to lock it down. Just like that, we had our custom hose, which we connected to the splitter as the start of our main irrigation line.

Step 4: Use Elbow Joints to Navigate Corners

To turn corners with your tubing, use a pair of sharp garden shears to make clean cuts where needed.

Insert an elbow fitting at each turn—these thread directly into the tubing and form a watertight seal.

Our main line had to turn a few corners, so we used a lot of elbow joints. We secured the tubing to our house using pipe straps.

Step 5: Connect a Timer to Automate Your Watering

We knew we didn’t want to manually turn the water on and off every day, so adding a programmable timer was a must.

I cut the poly tubing near our side gate (where I wanted the timer to hang), then attached a female irrigation adapter. The timer screwed right on, and from there I added a backflow preventer, a male adapter, and more poly tubing to keep the system moving toward the garden beds.

This step turns your drip setup into a low-maintenance dream, and it’s especially helpful during summer travel or busy weeks.

Step 6: Split the Main Line to Water Multiple Beds

We’ve got two garden beds, so the main line needed to split into two. I cut the line close to the corner of the first bed and set it aside. Then I dug a shallow hole underneath the corner of the bed for the tubing to run through.

Hot tip: do this before your garden beds are full of soil and plants. Digging under them later? Not as fun.

Step 7: Run Tubing Through the Garden Beds

Now comes the part where you connect the tubing through your raised beds. I took a long stake and drove it down through the top of the garden bed until it touched the ground. That gave us a nice, clean path for the tubing.

We fed the poly tubing down through the top hole and back up through the trench on the other side to meet the main line. To help the tubing turn smoothly and avoid kinks, I added an elbow fitting right where the tubing needed to bend. The fewer kinks, the better your flow—trust me.

Step 8: Use a T-Connector to Branch the Drip Line

Now that you’ve got tubing running through the first garden bed, it’s time to split the main line and send water to the second one. We used a T-connector to do this. One side of the T went to the tubing we’d just pulled through the bed, and the other side was prepped to continue to bed number two. These connectors grip the tubing easily and securely.

We then attached another length of poly tubing to the open end of the T, which would run to the second raised bed.

Step 9: Extend Tubing to the Second Bed

For the second bed, we basically repeated the same process: we dug a small trench near the corner of the bed, then drove a long stake straight down through the top of the bed to the ground. That created a clean path for the tubing to pass through.

We snaked the tubing down through the top hole and back up through the trench, connecting it to the tubing from the T-connector. At the base, we added another elbow to help it turn without kinking. Once everything was connected, the groundwork was basically done!

Step 10: Secure the Header Line Inside the Beds

Now we added another elbow joint at the top of the tubing so it could lay flat along the topsoil. This created the header line—the main line that would run through the bed and feed all the smaller drip lines.

We ran the tubing along the top of the soil, used landscape stakes to hold it down, and added an end cap clamp at the end of each line to keep water pressure strong.

Step 11: Add Drip Tubing + Emitters to Water Each Plant

Time to water those plants! I used a hole punch tool to punch holes into the header line, then cut lengths of 1/4-inch drip tubing that could reach each plant.

One end of the tubing went over a drip coupler and was inserted into the hole; the other end went over a drip emitter. We used stakes to hold each line in place near the base of the plants.

If you need to run tubing to multiple plants from one hole, use a T-connector. And if you accidentally punch an extra hole (which I definitely did), goof plugs will save the day.

Final Touches

Once everything was connected, we buried the poly tubing 4–6 inches deep to protect it from sun damage and avoid any tripping hazards. When you’re done, your drip irrigation system will quietly do its job while you sit back and enjoy your thriving raised bed garden.

Smart Watering Tips for Raised Bed Gardens

• Water early in the morning to reduce evaporation.
• Set your timer based on your local climate and season.
• Check for leaks, blockages, or dead batteries regularly.
• Use rainwater if possible—it’s better for your plants.
• Consider adding a rain gauge or sensor to avoid overwatering.
