How to Feed Sugar Water to Plants


Water is crucial to the life of the plant--without water a plant will die. Water is only of one of the components necessary in the life of a plant. The other two components required are air and soil. The combination of air, water and soil initiate a process called photosynthesis in which sugar is produced and used to feed the plant. Speeding up the process of photosynthesis by adding sugar to their water can help your plants grow faster. While sugar is beneficial to the growth of the plant, too much can be harmful so care must be taken in how much sugar is given to the plant.

Step 1

Measure 4 cups of water from a faucet into a pot. Place on a stovetop, heat on medium-high heat.

Step 2

Bring the water to boiling. Measure 1/4 cup granulated sugar and place into boiling water.

Step 3

Turn off the stove burner and remove the pot from the stovetop. Stir with a spoon until the sugar is dissolved.

Step 4

Set the pot aside until the mixture has cooled to room temperature.

Step 5

Pour the mixture into a watering can.

Step 6

Water the plants with the mixture every 3 days, using plain water on the other 2 days. Water the soil of the plants until it is well saturated.

  • An excessive amount of sugar can harm or kill your plants.
