Sugar in water when repottin

[Discus]

In extreme cases, some sugar in water may help plants to recover. However, I suspect for the most part, this will tend to cause issues with bacterial/fungal growth if the sugar is not quickly removed from the plant afterwards. (i.e. replanting a plant that's still covered in sugar water).

Certainly, irrigating a potted plant with sugar water would be a very bad idea; this sugar water treatment would only be done while the roots of the plants were being soaked out of the growing medium (or perhaps even as a soak prior to the removal of old medium).

I did once soak some plants that had sat in a post office inside a box for a month in some slightly sugary water (with various other fertiliser nutrients and some superthrive); I think I used about 1 tsp of sugar per litre of water. Amazingly, only one of them died (n=3).

Given the way that culturing plants in vitro works, they're certainly capable of taking up sugars via the roots, but whether all roots are equipped with the right channels, I don't know.
