The volume inside a 5/8-inch hose is 0.57 gallon, and inside a 1/2-inch hose, there are 0.25 gallon of water.

The flow rate for a garden hose is between 9 and 17 gallons per minute. Depending on the type of hose, the average garden hose can be anywhere from 12 to 13 gallons.

Truth is, you can really connect any two hoses if you have the right fit to begin with – that is you just screw on the male connector of one of the hoses into the female connector of the other hose.

A drip emitter can be attached to the end of 1/4-inch-diamter supply tubing, and the supply tubing can be plugged into the 1/2-inch-diameter drip tubing by using a 1/4-inch-diameter barbed coupling. Uncoil the 1/4-inch tubing to a plant, cut that tubing and push a drip emitter into its end.

Soaker hoses work best on level ground since they don’t allow for pressure adjustment at different points along their length. The radius of coverage is not quite as broad with soaker hoses as it is with drip systems. Soaker hoses are less precise than drip systems and can’t be installed underground.

How Many Emitters are Needed? 1 or 2 emitters per plant, depending on the size of the plant. Trees and large shrubs may need more. Obviously, using two allows for a backup if one clogs up (which happens now and then, even on the best designed and maintained drip systems.)

1. Step 1: Do Your Homework.
2. Step 2: Connect to an Outdoor Faucet.
3. Step 3: Lay Out the Tubing.
4. Step 4: Install Ground Stakes.
5. Step 5: Lay Tubing Around Shrubs and Trees.
6. Step 6: Position Sprayers for Ground Cover.
7. Step 7: Close Off the Tubing’s End.
8. Step 8: Cover the Tubing With Mulch.

With drip irrigation you want the water to be immediately absorbed into the soil as it comes out of the emitter. If you can find them I recommend 2,0 l/hr (0.5 gph) emitters. These are often called “1/2 gallon per hour emitters” in the USA. If you can’t find them, then use the 4,0 l/hr (1 gph) emitters.

Limit the use of ¼ tubing to no more than 12 inches in length per run. LENGTH OF RUN LIMITS: ½ inch tubing can run up to 200 linear ft. ¼ inch tubing should not exceed 19 ft in length.

Maximum Run Length & Maximum Gallons Per Hour (GPH)

Steps:

1. Attach a pressure gauge to the end of the garden hose that’s supplying water to the irrigation system.
2. Remove one of the emitters (drip nozzles) from the irrigation tubing and attach the pressure gauge.
3. To improve water pressure and flow, divide the irrigation system into two zones.

With a drip irrigation system, don’t think “minutes”. Think: “hours”. And water deeply, but infrequently (once or twice a week). Your goal is to apply enough water to penetrate the soil to a depth of at least 8 inches, preferably more.

Using drip irrigation allows you to concentrate the moisture at the root level by using strategically looped tubes with emitters around each rose plant for optimum saturation.

1. Place a drip irrigation connector kit onto a nearby water spigot.
2. Verify that your rose bush soil is friable and well-drained.
