I ordered some Yams which arrived about 3mnths ago. I have put them in the fridge until I found out when was the best time to plant them. We are on the Gold Coast. Many Thanks Rachel Rushton

I ordered & received some Yams this week & wondered when is the best time to plant them. We are on the Gold Coast. Many thanks Rachel Rushton

You really are sub-tropical not temperate - it runs all the way down the coast to Sydney, unless you are in the mountains in from the coast. This website says plant by the end of November. It also says grows like potatoes. - a good time to grow potatoes in this ZONE is plant April/May. Try then.

I've dug most of my yams so the grass grubs don't feast on them. I've cleaned and dried them. How can I now store them so they don't wither?

Store them in damp sand in a cool dark place. The damp sand (not too damp) will stop them from withering and the cool dark spot will stop them from sprouting for quite a while.

will these grow in Michigan

Yams/oka need about 5 months to grow before harvesting. They can be planted when the soil reaches about 17 degrees C (a bit over 60 degrees). if you can fit these requirements you should be right. Harvest them after the leaves have started to die down to give them the most opportunity to make size.
