Hello I've just been given a huge bag of Jerusalem artichokes. No problems in using them but I want to keep some tubers to plant out at then of winter /spring. Can anyone tell me how to store them until then.

Plant a few them out now. As sunflowers, they are prettier in a north facing spot. They'll be fine as long as they get a bit of water. Be warned they can be quite invasive over a couple of year period if you're not careful.

Google how to store them.

Do you think I could grow these in the Wairarapa? We have frosts to about -5 in winter.

I’ve seen them growing in a few Wairarapa gardens - not sure if people water them but I’ve also seen them growing along side the Ruamahanga under one of the bridges so I guess it should be fine!

Hi I bought some Jerusalem Artichoke tubers on trade-me a few months back and they have been dormant in the ground since about June. I am in Auckland, and the spot they are in is sheltered and sunny. NOTHING has come up yet. Should I worry?

Try checking here before planting anything. You planted early winter instead early spring. This is what happens when people plant out of season. If you had a wet winter they may be rotten. Dig around the tubers to see how they are.

Hi Roy Jerusalem Artichoke is great for diabetics. It is ALWAYS better to eat the real thing than rely on tablets or capsules. Tablets have no 'life force' and are basically a way for the pharmaceuticals to make money so they can increase their profits and distribute dividends to shareholders. There is no money in real food for big pharma so grow your own plants. They are very easy to grow and are extremely good for you. For numbness and tingles incorporate good quality salt into the diet eg himalayan or celtic sea salt. Salt allows the electrical signals or spark of information travel throughout every cell in the body via the nervous system. The salinity and mineral component of good salts is the same as our blood. AVOID table salt - it is a chemical substitute.
