Materials
Empty 2 liter bottle
Box cutter
Garden trowel

Instructions
Remove label from bottle

Cut a small slit in the bottom half of the bottle.  Put another slit on the opposite side of the first slit.

Turn the bottle upside down and put 3 medium or 5 small slits in the bottom.

Now fill the bottle with water and see how the water drips out.  It needs to be a slow drip.

Empty the bottle.

Take the bottle out to the garden and dig a wide, deep hole and bury the bottom 2/3rds of the bottle next to a plant.

Fill the bottle ¾’s full of water. And the water will slowly seep into the soil, keeping moist the soil around the plant roots.

Create as many as you want or need.

It is suggested that you fill the bottles daily, in the evening.


Second Version
Materials
2-liter or 20-ounce soda bottle. The smaller bottles work better for container plants.
something to make small holes (such as a nail, ice pick, or small drill)
a sock or nylon (optional)

Instructions
Remove label

Punch 10-15 small holes all over the bottom half of the plastic bottle, including the bottom of the bottle.

Place the plastic bottle in the sock or nylon. This prevents soil and roots from getting into the bottle and clogging up the holes.

The soda bottle irrigator is then planted in the garden or in a pot with its neck and lid opening above the soil level, next to a newly installed plant.

Thoroughly water the soil around the plant, then fill the plastic bottle irrigator with water. Some people find it is easiest to use a funnel to fill plastic bottle irrigators. The plastic bottle cap can be used to regulate the flow from the soda bottle irrigator. The tighter the cap is screwed on, the slower the water will seep out of the holes. To increase flow, partially unscrew the cap or remove it altogether. The cap also helps prevent mosquitoes from breeding in the plastic bottle and keeps soil out.
