Unroll the drip tubing out on the grass in a sunny location to warm up and help you straighten it. Run the pipe from your outdoor tape or to a hose that is attached to the tap. Loop the drip tubing around the palm tree at a distance of 6 to 8 inches away from the trunk. Cut off the excess tubing leaving a spare 4 inches at the end.
Use the shovel to dig a trench along the path of the drip tubing from the hose tap around the palm tree. Make the trench at least 1 inch deep. Fit the tubing into the trench and hold it at intervals with soil staples.
Screw a hose splitter onto the exterior tap or end of a hose attached to the tap. This will allow you to use a hose at the same time you are using the drip system. Connect the end closest to the hose tap with a valve assembly. Remove the nut and put the valve on the tubing and tighten over the entire thing with the nut.
Punch a hole in the supply line that is around the base of the palm tree and insert an emitter. These will just push into the hole. Make holes every 2 inches around the palm and put an emitter into each one.
Insert feeder lines in the same manner. Punch holes and insert 1/3 inch feeder lines cut to a length of 10 to 12 inches between every emitter. The plastic tubing will close up around the lines. Dig small channels to fit the feeder lines in. These should radiate out away from the palm tree to water its peripheral roots.
Fill in all the trenches and channels. Test the system by turning on the water for 30 minutes. Look for damp spots under the tree that will indicate the system is working. You need to provide as many gallons per week of water as your tree would need in a nursery pot size. For instance if it would fit in a 25-gallon container it needs 25 gallons of water.
Calculate how much water you give each time. Count the number of emitters you installed and multiply by 10. That is how many gallons of water you will administer per hour every time you turn on the system.
