We are going on vacation and I would like to know about the self-watering system for plants using gallon milk jugs. I remember something about putting rocks in the jug, poking holes and sticking it in the ground next to the plants.
You can make useful self watering planters from recycled everyday materials found at home. A wick system will keep the soil moist and your plants healthy.
To water outside plants while on vacation, simply bury a piece of yarn beside of plant and run the other end of yarn into a bucket of water. Presto! The plants will absorb water as needed. Happy gardening!
