Don’t pollute with plastic soda bottles. Take a few seconds and make a self watering planter. It is so easy and tested by me. Just cut the top off. Loosen the cap.
Flip it upside down and shove it back in the bottle. Before this you can cut the sides of the top you cut off to make it go down easier. Some people add a string between the inverted top and soil mixture for wicking, but it is not really needed. I love these easy self watering planters. Listen to podcast episode 15 for details!
