Giant Rhubarb Q's

I purchased some Giant Rhubarb seed from ebay about 4 or 5 weeks ago. I now have 6x 4-5cm shoots groing very nicely. I currently have them all in a single 6ltr pot. My question is, are these too small/fragile to now move to their owns pots? or should i let them establish themselve more?
Im expecting these to grow rapidly and intend to plant them in the garden next year. Which would be the best month to plant them in the ground? and also how far apart should i plant these as i know the grow LARGE?

Thx Wayne

P.S. not sure if i should have posted in the Tropical section or not?

 

I can't find a lot with a quick 'google' except this, http://www.gardeninglife.ca/articles/article/grow-your-own-gunnera/ but you may have time for a bit more searching. If, by 'giant rhubarb' you mean Gunnera Manicata which grow to about 4m, I'm thinking that eventually you're going to need a pot considerably larger that 6 ltrs. :hehe:

 

Hi

Took some pics of our giant rhubarb which i thought you may like to see. Can't really comment on whether you should plant this yet, but i can confirm it grows very fast and i regularly cut stems off. Also read that it requires a lot of water.

 

Cheers for the link Fidgetsmum

Cracking pictures there will! Mine are now 10-12cm now and growing fast!!!

Thanks, just been reading about slow release fertilizer that you can use such as this product, may give this ago, but I haven't done anything special for mine other than a good watering every evening.

Not a bad idea, i might try these myself.
Yes i had read that they need plenty of water, and i also water mine each evening. I hope mine turn out as nice as yours my friend.

are they edible?

 

I think some of the Gunnera species are edible but not sure about this one.

 

im pretty sure they are inedible an can cause irritation if ate

i use to have one, sitting in a bucket of water

i may be wrong on this but im pretty sure its a bog plant, hence why you generally see it planted next to ponds an things
