The cells inside each plant are miniature factories that produce a sugar known as glucose for energy. This sugar is the byproduct of photosynthesis. Additionally, when you purchase cut flowers, some florists give you a packet that contains glucose and citrus to feed the flowers and help preserve them and hold off wilting. You can make up your own sugar water at home to feed plants in order to boost their blooming and growth.
Fill a saucepan with 4 cups of water. Bring to a boil.
Add a quarter-cup of sugar to the water. Stir while still boiling with a spoon until dissolved. Then remove the still-boiling water from heat and allow to cool.
Add the solution to a watering can. Water plants with sugar water twice monthly by tipping the sugar water into the plant pot until the soil is as saturated as a wrung-out sponge.
Save your sugar water in the refrigerator when not in use. This will retard the growth of bacteria.
