what would sugar water do to a plant?

Answer 1

it seems to be a popular science experiment. :)
sometimes it's good in small amounts, but too much is bad. generally, plants prefer to "brew their own" sugar. except for certain parasitic plants.

here's some informative answers from the web:

"Sometimes a pinch of sugar is added to water and fed to a plant that has wilted and hasn't been watered for a while. The sugar can help the plant quickly get back to normal. However, this doesn't always work and sometimes the plant might be too far gone to save. Also, sometimes a pinch of sugar is added to the water that cut flowers are sitting in order to preserve them for a bit longer. However, sugar is not usually added to the water that is fed to normal, healthy plants."

"Part of the scientific reason plants die due to being watered with sugar water relates to osmosis. When you have a higher concentration of sugar water outside the roots than inside the plant, then water will leave the roots and thereby dehydrate the plant. There could also by a myraid of other reasons, including providing an easy, usable food source for soil microorganisms, who might proliferate and take up nutrients that would otherwise be available to the plants or the microorganisms might produce an excess of harmful gases that stunt plant growth. Also, different plant species and even different plants will react differently to varying concentrations of sugar, i.e. one plant might do fine getting a 5% sugar solution, while another one dies."

Answer 2

normally the plant will grow faster.
But if the content of sugar more than the limit.
the plant will.... die faster also.

Answer 3

it would grow extrmly fast, then probably start to eventually loose it's leaves because it doesn't need to make it's own sugar anymore

Answer 4

It'll make it grow, but it'll also attract bugs to it's root and stem area - thus getting them chewed off...ie. it may die.
