Sugar feed for white variegated plants= increased vigor?

Posted by jostus 6 (My Page) on

I know that variegated plants don't produce as much sugar in their leaves as fully green plants due to less chlorophyll in their leaves.

Would it then be beneficial to feed variegated plants a little bit of sugar to make up for what they can not make on their own?

jostus, it sounds so logical doesn't it?
Roots take in nutrients as ions. When salts like ammonium sulfate, potassium chloride etc. dissolve in the soil water, they break up into ions. The mineral ions in the soil water displace (hydrogen) ions on the root hairs of the plant and these are assimilated into the Xylem via the root tissues.
Sucrose (cane sugar) does not disassociate into ions. Molecules of the solid sugar bond with molecules of water and cannot be used directly by the plant.
It is similar to the idea that the application of lime to citrus trees will make the fruit less acid (sour). After all, doesn't lime reduce acidity?
Disclaimer: It has been many years since I had to recall this sort of thing.
I am acutely aware that my knowledge may be out of date.
I welcome enlightenment.

Ronalawn, Your logic makes more sense.

The plant I feed sugar to was a very highly variegated Epipremnum aureum 'Marble Queen' (more white then green)

The plant seemed to react well to the sugar.
Do you think it Is then possible the sugar was broken down by bacteria and then used by the plant simply as another carbon source?

jostus, yes! However, the process is biochemical in nature and can produce (gaseous) products which would be unwelcome indoors.
