“A wine bottle works best for this purpose because it’s both sturdy and capable of holding a large amount of water.
“However, any bottle with a small mouth will also work just fine.
Start by pouring water into the bottle, making sure to leave a few inches at the top.
Then cover the opening with your thumb and turn the bottle upside down.
The experts advised: “At the base of the plant where you water, shove the upturned bottle inside the soil, remove your thumb just before doing that.
“For the bottle to stay fixed, push the neck several inches below the soil’s surface so it remains stable.”
