I think it would the same process as for arrowroot. Perhaps look that up online and see if any instructions or advice is available?
Sorry Pollyanna, Cassava is something I'm still getting used to growing and handling, and eating. Why not just give it a go with some of your crop?
Jo Perren on the Sunshine Coast is an expert with sub-tropical veg. She's just done a free workshop at the Yandina Community Gardens which unfortunately I couldn't attend.
If you could contact Jo, perhaps via the YCG, she might be able to give you some ideas.
She cooked the coconut milk / cassava cake for us once. My goodness it was delicious.
My entire cassava crop was wasted as it went off very quickly after harvesting - something I did at the beginning of summer when the tops died off. Surprised yours are still growing. I tossed the pieces into the garden and they are regrowing all on their own without even being stuck in the ground! Tough stuff.
Let us know what/if you find out anything about your two different varieties. I only have whatever a gardening friend gave me a couple of years back - no idea which it is. To be honest it hadn't occured to me that there were different varieties! But of course there had to be like most things.
New plants are created friom cuttings of the stem, so once you've dug these up you don't need to worry about replanting these particular plants. You just start all over again with new cuttings. Or do as I did and toss them on the ground!
Oddly enough, I had a response this morning about cassava cake from a comment I left on Youtube ages ago.
5 Cups grated cassava, 2 cups coconut milk,1/2 cup brow sugar 1 tbsp vanilla ,2 tbsp. melted butter , 2 eggs , 1/2 cup condensed milk and 1/2 cup pineapple ( to make it soft ) mix well & bake ( 250) for 30 mins.or until almost cook. Then add the toppings which was cooked ahead ( Combine 2 cups coco milk , 1/2 cup brown sugar , 1/2 cup condensed milk - cook until it gets brown ). then add this to the top of half cooked cassava then baked it again until brown. Enjoy !
Have you tried Youtube for ideas of what to do with your Cassava? It's amazing how much info you find there if you take the time to hunt for the good stuff.
Jo has done three workshops that I know of so far so there should be more to come. There's hope for you yet :) I've missed the last two myself.
Keep an eye on the Yandina Community Gardens workshops or follow events on BLF as I usually keep these updated with their workshops as they do such good ones.
Hopefully you can talk/email with Jo herself for some pointers....which you can then share :D
You must be growing stuff up there at Toowoomba that we can only dream about down here on the coast. I would love to grow a stone fruit of some kind - I was reading about one suitable for sub-trop the other day but I can't remember where it was.
I've started a blog on Seed sites and fruit tree sites, so if you hear of any places selling either please let me know.
I've added Flemings :) There aren't any places in Qld that I've heard of, yet they must exist.
I was reading about these crossed fruit trees yesterday. I would love to grow a stone fruit that is truly suited to Brisbane climate. Not something that I will wait disappointing years for fruit only to find that they just aren't worth the bother.
Once you start growing some of the more unusual fruit and veg you do want to let others know about them.
Try adding them in small doses to your cooking with prominent bits of more accepted veg clearly visible. I've found roasts a good way to introduce things like Arrowroot, roasted green pawpaw (delicious and just like roasted sweet turnip) and stirfries are a good way to introduce things like Winter Melon and all those wonderful greens like Aibika, Amaranth, Egyptian Spinach, Kangkong. In salads you can introduce grated green pawpaw, Jicama, Carambolo and Yakon. I wait until the meal is over to tell people what was in it lol.
You could always start a Toowoomba sub group on the site if you can find enough people up there interested in joining you. Garden visits and seed saving get togethers? You could troll through the 1500 members and see if any others are in Toowoomba :/
My daughter Erin works up that way at Downs Heating and Cooling. Say hi if you go in :)
