what you need..
-large square plastic water bottle
-scissors or knife
-soil
-tack or pin
-plant
-string (optional)

Step 1: Cut the Bottle

cut the bottle so the top half (which will be the planter) is just a bit larger than the bottom half.

Step 2: Puncture Cap and Add Soil

use a tack or pin to puncture holes in the bottle cap and add a layer of soil to get ready to transplant your plant.
place the planter in the other half of the plastic bottle with the bottle cap facing downward.

Step 3: Finishing Up

Place the plant in the planter and fill with soil.
(optional) pierce the sides of your planter with a knife and attach a string to make it a hanging potter.
Now you have a semi- self watering reused planter.
Add a little green to your environment and save a little green on planters!
Have Fun!
