Homemade drip water containers are made from recycled plastic bottles. You need a plastic bottle, dish soap, a drill and a flat rock. Choose the bottle size according to the size of the pot. This process takes under an hour.
Prepare the plastic bottle
Remove the cap from the plastic bottle. Wash the inside of the bottle and the lid with warm, soapy water. Rinse thoroughly. Drill four to six holes in the lid with a 1/4-inch drill bit. Drill additional holes if you want the water to drip faster. Drill a 1-inch hole in the center of the bottom of the bottle. Replace and tighten the cap.
Dig a hole for the bottle
Dig a hole within 8 inches of the base of the plant, being careful not to disturb the roots. Dig the hole deep enough to bury half of the bottle.
Plant the bottle
Place the bottle cap side down into the hole. Press soil around the bottle to hold it in place.
Fill the bottle with water
Fill the bottle with water using the 1-inch hole drilled previously. Place a flat rock over the hole to prevent soil from settling into the bottle. Refill the bottle when the water level gets low.
