Hi, How do we go about ordering some seed yams? What's the best time for our area to start planting? We live in Moore Park Beach, just north of Bundaberg. What sort of soil do they grow in? We have sandy loam and grow red sweet potatoes, but would love to try our hand at yams if they grow here. Thank you,

In the notes here it says they are grown similar to potatoes which would include Sweet Pots. Look on the internet for sellers. The diggers club or ebay have them. As long as the soil is friable and you add compost/fertiliser etc you can grow most things. A good time to plant potatoes in Bundy is in May so you could plant any time from now. I'm at Coral Cove the other side of Bundy. Mike Logan - phone if you like.

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.
