How to Feed Plants Carbonated Water


Plants appreciate carbonated water as much as human beings. In fact, plants watered regularly with carbonated water grow more quickly than plants watered with flat water. According to biologists at the University of Colorado at Boulder, carbonated water contains high levels of carbon dioxide, oxygen, phosphorus, potassium, sulfur and sodium which are all essential to plant growth. And carbonated water doesn't just feed the plants. It increases their ability to absorb essential nutrients already present in the soil, like potassium, calcium, iron, magnesium and zinc.

Step 1

Spread a 1 to 2 inch layer of organic mulch over the planting bed. According to experiments conducted at Colorado State University in the late 1980s, carbonated water increases plant yield most effectively when mulch is laid.

Step 2

Pour the room temperature carbonated water out of its container and into your watering can. Let it settle for five minutes.

Step 3

Water the plants with carbonated water. Use the same amount of carbonated water as the amount of flat water you usually use to water your plants.
