How To Make Self Watering Planters

I’ve been wanting to make these for a long time. Since I don’t often have plastic pop bottles lying around the house, it took a while to gather enough supplies. I made three or four of these a week ago and they are a definite success. The soil stays moist without any extra watering from me.

The basic idea is that you fill the bottom part of the planter with water, have one side of the yarn resting in the water, while the other reaches up into the soil. You won’t need to water them every day, simply refill the reservoir when it gets low.

Supplies you will need in addition to a medium-sized plastic pop bottle:

  • hammer
  • screwdriver
  • scissors
  • yarn

Instructions:

  • Start by cutting the pop bottle in half. I like to keep the top half (the one with the cap) longer than the bottom so there is a lot of room for growth.
  • Poke a hole in the cap of the bottle with a screwdriver and hammer. This is the most difficult part. As you can see in the above photo, my screwdriver is stuck to the popcap.
  • Thread a piece of yarn through the pop bottle cap so that there is an equal amount of yarn on either side.
  • Put the top end of the bottle inside the bottom part of the bottom with the cap facing down.

  • Fill the bottom portion with water. This is your reservoir
  • Fill the top portion with dirt and plant your seeds! Make sure that the yarn is buried partway up the bottle so the moistened yarn will reach up to the roots.

You can also put starts in these. I’ve currently got radish, sage, dill and carrots growing!
