For vegetable gardens, we suggest the following two options:

Option 1: Drip line with 1 GPH dripper every 18″. This system can last for 7-10 years
Option 2: Drip tape with drippers every 12″. This system can last for 3-5 years

Option 1: Using dripline with PC drippers every 18″
Our suggestion is to use 1/2″ drip tubing as the main line and run the drip tubing perpendicular to the vegetable garden beds or rows. Near each row or bed of vegetable cut the 1/2″ drip tubing and add a 1/2″ tee. Into the tee connect the 1/2 drip line with 1 GPH drippers every 18″ (model B18100) and layout the drip line close to the row or at the center of the vegetable bed. After the installation is complete, turn the water supply on and flush the line, then use a hose end to close the end of the drip line and the drip tubing. Pressurize the system again and make sure that the system is working with water flowing from all the drippers along the drip line; confirm that there are no leaks. This system can be used for a vegetable garden with any numbers of rows for a total flow rate of up to 220 GPH

If you have more than one bed spread around the garden, you can control the flow on each bed by adding a ball valve. To the 1/2″ tee connect a section of 1/2″ drip tubing and run it into the bed. Connect a 1/2″ ball valve into the drip tubing, and from the ball valve continue with the 1/2″ drip line inside the bed and repeat for each additional bed.

See the list below with what we think are the best steps to help you to install this system. Please be aware that all installation applications are different. If you do not find the exact information that pertains to your application, send us an email with what you like to do for your particular situation. All our drip hoses and fittings are UV resistant, and are good for above-ground installation.

Parts suggestion:

  • Optional: Hose End Timer (low flow), model BO9D or BO92A. Connect to the faucet.
  • 3/4″ FHT back flow device #10. Connect to the controller, or if a controller is not used, connect to the faucet. The backflow protects the system from contaminated water re-entering the water supply.
  • 3/4″ FHT screen filter with 155 mesh #13. Connect the filter to the backflow device. The filter is used to protect the drippers from plugging. The filter screen needs to be removed for cleaning from time to time.
  • 3/4″ FHT 25 PSI pressure regulator #4. Connect the pressure regulator to the filter.
  • 3/4″ FHT swivel adaptor #18. Connect the swivel adaptor to the pressure regulator.
  • 50, 100, 200, or 500′ roll of 1/2″ drip tubing, models B35, B36, B39 or B37. Connect to the swivel adaptor and layout the drip tubing perpendicular to the vegetable garden beds or rows.
  • Tees 1/2″ x 1/2″ x 1/2″ (if needed) #19. Used to split the 1/2″ tubing if needed near each row or bed.
  • Ball valve #64. Add to each bed, if needed ,to give you a complete control for each individual bed (optional).
  • 100′  dripline, model B18100, with 1-GPH drippers every 18″. Connect the drip line to the to the drip tubing using the tee and layout the dripline near the vegetable rows.
  • 1/2″ coupling (if needed) #17. To connect two pieces of 1/2″ drip tubing or dripline
  • 1/2″ hose ends #71 (pack of 1) and #55 (pack of 5). After you install the 1/2″ drip line and the drip tubing, turn the water on and flush the line, then close the end of the 1/2″ drip line, pressurize the system, and make sure that the system have no leak.
  • 1/2″ stake #60 (pack of 1). Use to hold the 1/2″ drip tubing and drip line into the ground. Place as needed.
  • Plugs (if needed) #56 (pack of 10). If any holes on the 1/2″ drip tubing or drip line you can use the plug to close the hole.

Option 2: Using a drip tape with dripper every 12″
This suggestion is for installing a drip system in a vegetable garden with any numbers of rows for a total flow rate of 220 GPH (same as with drip line)

The best way to install drip tape for a vegetable garden, is using the drip tape with a 1/2″ drip tubing as the main line. The drip tape is thin walled drip line with drippers every 12″ with a flow rate of 80 GPH per 100′. The best installation method is to use the 1/2″ drip tubing as the main line perpendicular to the vegetable rows. Near each row connect the drip tape to the drip tubing using the drip tape reducer connector. If the bed has more than one vegetable row with spacing between each row of more than 10″, then install the drip tape between two rows. You can use the drip tape above or below the ground with up to 10 rows, each 30′ long

Parts needed:

  • Optional: Hose End Timer (low flow), model BO9D or BO92A. Connect to the faucet.
  • 3/4″ FHT back flow device #10. Connect to the controller, or if a controller is not used, connect to the faucet.
  • 3/4″ FHT screen filter with 155 mesh #13. Connect the filter to the backflow device.
  • 3/4″ FHT 25 PSI pressure regulator #4. Connect the pressure regulator to the filter.
  • 3/4″ FHT swivel adaptor #18. Connect the swivel adaptor to the pressure regulator.
  • Tees 1/2″ x 1/2″ x 1/2″ (if needed) #19. Used to split the 1/2″ tubing if needed near each bed.
  • Near each row, punch a hole in the 1/2″ drip tubing and insert a drip reducer connector #29 (pack of 2). Connect the drip tape to the connector, and run the tape along each bed.
  • Drip tape model ST100R or drip kit model ST100 with 100′ of drip tape. Connect the drip tape to the to the drip tape connector and layout the drip tape near the vegetable rows. After you install the drip tape, turn the water on and flush the line.
  • Close the end of the drip tape using drip tape end #28 (pack of 2). Close the end using the connector, pressurize the system and make sure that the system working to your satisfaction and the system has no leak.
  • Punch #51 or #52 (pack of 1). Use the punch to punch the holes in the drip tubing for insertion of the connectors.

Turn the system every day for about .45 minutes to 1 hours depending on your location and the soil type. After a week check the soil, the health of the plants, and adjust the watering time as needed.
