Drip tape is the go-to irrigation for long vegetable rows. It is inexpensive, quick to lay and delivers water evenly along the whole row. Knowing how to install drip tape correctly, from choosing the right thickness and emitter spacing to building a header and closing the ends, makes the difference between a system that runs smoothly all season and one that leaks, kinks or waters unevenly. This guide covers each step.
For the overall drip system, see our guide on how to set up drip irrigation. For a broader vegetable garden plan, see drip irrigation for vegetable gardens.
Why use drip tape?
- Low cost per foot compared with heavier tubing, which matters for large gardens.
- Fast installation: unroll, connect and pin.
- Even watering along long rows.
- Dry foliage, reducing leaf diseases common with overhead watering.
- Water efficiency, since water goes to the root zone with little loss.
- Easy seasonal setup, laid in spring and removed in fall.
What drip tape is
Drip tape is a thin-walled, flat tubing with emitters built in at regular intervals. It lies flat when empty and rounds out when pressurized. It is used widely on farms and market gardens, and works just as well in large home vegetable gardens with straight rows.
Drip tape vs drip line
| Feature | Drip tape | Inline drip line (tubing) |
|---|---|---|
| Wall | Thin, flat when empty | Thick, round |
| Lifespan | Often one to a few seasons | Many seasons |
| Cost | Low per foot | Higher per foot |
| Pressure | Low; needs regulation | Low to moderate; needs regulation |
| Best for | Long, straight vegetable rows | Beds, borders, permanent plantings |
Choosing drip tape
The right tape depends on your soil, crops and whether you plan to reuse it.
| Spec | What it means | How to choose |
|---|---|---|
| Wall thickness (mil) | Thicker tape is tougher and lasts longer | Thin for one season; thicker for reuse |
| Emitter spacing | Distance between built-in emitters | Closer for sandy soil and dense crops |
| Flow rate | Water output per emitter or per length | Lower flow suits clay and long rows |
| Diameter | Width of the tape | Match fittings to the tape size |
For a home garden, a moderate wall thickness with emitter spacing of around 8 to 12 inches suits most crops. Use closer spacing in sandy soil or for densely planted crops like carrots and greens.
When to install drip tape
Lay drip tape after preparing beds and before or right after planting or transplanting. Installing it first makes it easy to plant along the line and avoids damaging young plants. For direct-seeded crops, lay the tape before sowing and run it briefly to moisten the seed row. For transplants, lay tape first and plant next to the emitters.
Parts you need
- Drip tape
- A header: solid poly tubing running across the ends of the rows
- Drip tape fittings: start connectors, couplings, tees and end closures sized for your tape
- A hole punch for the header, if your start connectors need it
- A faucet head assembly: backflow preventer, filter and pressure regulator suitable for drip tape
- Stakes or soil pins
- Scissors or a sharp knife
For the faucet end, see our guide on the drip irrigation head assembly.
How to install drip tape step by step
Step 1: Prepare the beds
Good preparation protects thin tape from damage. Shape and smooth the beds or rows before laying tape. Remove sharp rocks and sticks that could puncture thin tape.
Step 2: Lay the header
Run a header line of solid poly tubing along the end of the rows, a short distance from the bed edge. Connect it to the water supply through the head assembly.
Step 3: Install start connectors
Space the connectors to line up with the center of each row. Punch a hole in the header at the center of each row and insert a drip tape start connector, or use connectors that thread into a header fitting. Many connectors include a small valve so you can shut off individual rows.
Step 4: Attach the tape
Slide the end of the drip tape onto the start connector and tighten the locking collar or ring. Make sure the emitters face up.
Step 5: Lay the tape along the row
Lay tape in the cool part of the day if possible; warm tape stretches, then shrinks when it cools. Unroll the tape down the row, keeping it straight and without twists. Place it near the plant line, or between two plant rows if they are close together. Pin it in place with soil staples every few feet.
Step 6: Flush the lines
Before closing the ends, turn on the water and let it run until it comes out clear.
Step 7: Close the ends
A secure end closure is what keeps pressure in the row. Fold the tape end back on itself a couple of times and secure it with an end closure, a short sleeve of tape or a figure-eight fitting, or use a dedicated end plug.
Step 8: Test and mulch
Walk every row while the water is on. Run the system, walk each row and check for leaks, kinks and dry spots. Cover with a light mulch to protect the tape from sun and reduce evaporation.
Surface vs shallow burial
Most home gardeners lay drip tape on the surface and cover it with mulch. It stays easy to check and repair, and there is less risk of soil being drawn into emitters. Some growers bury tape very shallowly to protect it from sun and tools, especially in long-season crops. Deeper burial makes repairs harder and is generally best left to systems designed for it. Our guide on how deep to bury drip line compares the options.
Using drip tape with plastic mulch
Many vegetable growers lay drip tape under plastic mulch film for crops such as tomatoes, peppers, melons and squash. The film warms the soil, suppresses weeds and reduces evaporation, while the tape delivers water underneath. Lay the tape first, flat and straight along the bed, then lay the film over it and secure the edges with soil. Cut planting holes carefully so you do not slice the tape.
Running drip tape at the right pressure
Drip tape needs low pressure. Too much pressure can split tape or blow off fittings, and too little leaves the far end of long rows dry. Use a regulator rated for drip tape and keep rows within the manufacturer's maximum length for the tape's flow rate.
How long to run drip tape
Run time depends on the tape's flow rate, row length and how much water crops need. Calculate total flow for each row, then work out how long it takes to deliver the water needed. Our guide on how long to run drip irrigation explains the calculation and how to check soil moisture.
Layouts for different crops
Single rows of large plants such as tomatoes, peppers and squash: one line of tape along the plant row, close to the stems.
Double rows of crops such as beans or lettuce planted in two lines: one line of tape down the center, between the plant rows, works in many soils.
Wide beds of greens or carrots: two or more lines of tape per bed, spaced so the wetted areas overlap.
Sandy soil: use closer emitter spacing and keep tape near plants, since water spreads less sideways.
Clay soil: use lower-flow tape and longer, less frequent runs so water soaks in without puddling.
Common mistakes
- Emitters facing down, inviting sediment to clog them.
- Twisted tape, which kinks and blocks flow.
- Rows longer than the tape's rated maximum, leaving the far end dry.
- No pressure regulator, causing split tape and blown fittings.
- Skipping the flush before closing ends.
- Running over tape with tools or wheelbarrows.
- Leaving tape exposed to strong sun all season without mulch.
- Not checking for pests such as rodents or insects that chew tape.
Drip tape in raised beds
Drip tape can work in raised beds, but inline drip line is often easier for short runs because it holds its shape and is more durable. If you use tape in raised beds, run a header across one end and lay short lengths down the bed. Our guide on drip irrigation for raised beds compares options for beds.
Planning quantities
Measure each row's length and count the rows. Total tape needed equals rows multiplied by length, plus a little extra for end folds and repairs. Count start connectors (one per row), couplings for repairs, end closures and the header length. Check the total flow of all rows against your water supply and regulator ratings. If it is too high, split the garden into two zones.

Repairing drip tape
Small punctures from tools or animals are common. Cut out the damaged section and join the ends with a drip tape coupling. Keep a few couplings in your toolkit.
Troubleshooting drip tape
Far end of the row is dry: the row may be too long for the tape's flow, the pressure may be too low or the filter may be clogged.
Tape will not round out: pressure is too low, or a kink or fold is blocking flow near the start.
Water spraying from a split: pressure may be too high, or the tape was damaged; repair with a coupling and check the regulator.
Connector leaking at the header: the hole may be too large or the connector not fully seated. Replace it or use a goof plug and punch a new hole nearby.
Uneven wetting along the row: some emitters may be clogged. Flush the line by opening the end.
End-of-season care
- Flush the tape before removing it.
- Lift tape carefully, roll it up and store it out of the sun if you plan to reuse it.
- Discard thin tape that is brittle or damaged.
- Drain and store the head assembly indoors in freezing climates.

The bottom line
To install drip tape, choose a tape with suitable thickness and emitter spacing, lay a solid header across the row ends, connect a length of tape to the header for each row with emitters facing up, pin it straight along the row, flush and close the ends. Run it at low, regulated pressure, mulch lightly and repair punctures with couplings. Lift and store reusable tape at the end of the season.
Frequently Asked Questions
How do I install drip tape?
Run a header line across the end of the rows, connect a length of drip tape to the header for each row with emitters facing up, lay it along the row, then fold and secure the far end.
Should drip tape emitters face up or down?
Usually up, so sediment settles away from the emitter openings. Follow the manufacturer's guidance.
What pressure does drip tape need?
Drip tape runs at low pressure, typically lower than standard drip tubing. Use a pressure regulator rated for drip tape and follow the manufacturer's range.
Can drip tape be reused?
Thicker tape can often be reused for several seasons if handled carefully. Thin tape is usually used for a single season.
Should I bury drip tape?
Lay it on the surface under mulch, or bury it very shallowly. Burying too deep makes it harder to inspect and repair.
