Have you tried growing Gingers?

Well, we have some gingers (Roscoea) in our garden in Moray and they grow very well. They are an attrative plant and I like them.

I have Hedychium Tara and Cautleya spicata which do pretty well. The Cautleya is hardy and likes semi shade and the hedychium less hardy and may like a bit of protection depending on where you live.

I have a Hedychium and two types of Roscoea. The former needs some protection but the latter genus is quite hardy coming from Himalayan sub-alpine meadows/tree line edges.

I grow hedychium 'Tara' as well - it's supposed to be the hardiest variety and came through last winter (-8C) with a thick straw mulch over the roots

I'm growing Ginger asda vegdept in my greenhouse in a 2 gallon plastic tub. The tub is now being distorted by the plant and the ginger is sprouting from nodules above the soil level.
Anyone know when to harvest?

When it starts to die back for it's "winter" rest after about ten months from sprouting.

I obtained a Hedychium and a Cautleya spicata earlier in the season and all this advice is wonderful...thanks and thankyou Weedpatch for asking the question....:>)

Thanx, Fractal, appreciate the advice.

Please pardon my ignorance, but does talk of 'harvest' and 'sprouting nodules' mean that these are actually the plants we get the edible ginger from? What about stem ginger? Does that come from these aswell?

No, the plant we get stem and root ginger from is zingiber officinale. The Hedychiums, Roscoea and Cautleya's are ornamental gingers. You can root a root ginger (zingiber officinale) from the supermarket if you have time and patience, I have grown some in a pot before, but forgot them over Winter and they karked it!!

Weedpatch, in my case, 'harvest' and 'nodules' do indeed refer to the edible type from a piece of supermarket bought ginger. My wife had bought some fresh ginger and was about to discard a dessicated piece when I got my eye on it. I'll try growing that I thought...so I did.
I'm not sure where, when or how to harvest stem ginger.

To be honest I thought the original question from you meant edible ginger as I didn't know there was any other type.
So a big "thanks" to all the above members. I now know differently.

p.s. just had a thought. Fractal, now knowing I was talking about edible ginger, does your answer still apply?

After your helpful comments, I think I am going to try both ornamental and edible ginger.
Jungle Seeds have quite a selection and the photos are lovely, including ones you have named. I hadn't realised they were quite so varied or beautiful although I will be going for the hardier ones.
Thanks
