Ginger!

get the root wash it with warm water , let it rinse untill almost dry , place in a clear plastic bag and put in a really warm place and forget about for a week .

do not overwatering or it will rott .
and make sure lots of heat

 

Are you talking of a piece from the supermarket - or an ornamental ginger?

Sal is right. I am sure that rhizomes and tubers need lots of heat to start, but don't need any water until they get rooted and some topgrowth.

 

It should grow - I have grown one before. The only problem is that it wasn't ornamental - and therefore didn't do much. I think I got bored with it after a bit.

I am currently growing a couple of ornamentals, that seem to be much bigger plants - perhaps just older. They haven't flowered yet - but I am living in hope.

 

As an olf phart and buying 'stuff' on Wednesday (as it's 10% off) from B & Q, I saw there were ginger tubers/corms for sale outside.

Cheers, Tony.
